A Advanced Septic & Construction ServicesExcellentA Advanced Septic & Construction Services4.8 Based on 2358 reviews fromSee all reviews review us onRobin HealeyRobin Healey ★★★★☆ I need to have my septic tank pumped and made an appointment with the office. They were able to come out rather quickly and they respond quickly on the phone as well. They gave me some good advice on how to maintain my system as well as give me prices for installing risers for my system since there is fill over my tank. They are very professional and I will definitely use them again for all my septic system needs!Claire RainerClaire Rainer ★★★★★ Such a great experience. We were new to septic life and their office was so friendly and helpful, and they sent a crew out the next day. The guys that showed up taught us all about the system we had, and were super nice, which was worth every penny. Thanks so much for the help!Mindy DowningMindy Downing ★★★★★ This company has some of the best customer service! From the first phone call to the last service and payment! Every thing was explained to me and all questions answered! Never seem like you are pestering them! I would highly recommend them without question!Jamie FarnamJamie Farnam ★★★★★ The customer service, from the initial phone call to the completed job, was outstanding. I called them at 6:30pm and they had professional, knowledgeable Techs at our house within 30-45 minutes. This company made a very stressful situation so much easier! Highly recommend!Samuel GeresuSamuel Geresu ★★★★★ Following my online review, I reached out to "A Advanced Septic & Construction." I'd like to express my gratitude to the office staff for their kindness and respectfulness. Our experience with the technician team, Thomas, and his partner last week was exceptional. Their careful attention to detail and clear explanations of the work left us thoroughly impressed. We are extremely satisfied with their service and would wholeheartedly recommend them to others.KellyKelly ★★★★★ We had our drain field tested, cleaned out and repair work done. Marcus and Eliseo did fantastic job! They spent time ensuring it was done correctly and explained everything thoroughly along the way! I highly recommend A Advanced Septic!LOIS NOBLELOIS NOBLE ★★★★★ Great team approach! Andrew and Alexander did a great job for us. Quote was clear, on time. Alexander came out and quickly found our septic to put in riser. Andrew came out the next day to pump and replaced baffles. Worked in the rain and gave us a clear understanding of our system. Thanks for a job well done!Bree McCartyBree McCarty ★★★★★ We called around two 4 different companies and decided on A Advanced. They were not the cheapest option out of the 4. But the price difference was a difference of 20 bucks. What I liked is they were up front with all the fees. They also were able to be out to our house within the time frame given.They had great communication, and once they arrived very professional. Pumping septic systems is not glamorous work. But, they got the job done, and were so helpful. They even send you pictures of what was done. So, you can keep for your records.walt danielwalt daniel ★★★★★ Eric was the most professional and knowledgeable about his job. So helpful and explained everything ahead of time to not blind side us with extra expenses before he proceeded with the job. He is a 5 star employee and would highly recommend this company for all your septic needs🤩brian iardellabrian iardella ★★★★★ My wife and I contacted “A Advanced Septic & Construction” because we had a backup in our septic line. Eric Hawkins came right out, and from the moment we met him he was a pleasure to deal with. He resolved our issue right away, explained to us what caused it and was straightforward about potential future issues to keep an eye on. Eric was very informative, down to earth and a great guy to speak with. Thank you for all of your help Eric. And on a personal note…thank you for your service in the military! We will definitely use “A Advanced Septic & Construction” in the future. And we highly recommend “A Advanced Septic & Construction” to anyone who may have septic issues too. Thanks again Eric for all of your help.jer jerjer jer ★★★★★ Cory H n Chris H n Guillermo did a fantastic job over here at the Golden Rose Park today. My place was backed up n bubbling out of the shower. They diagnosed the issues, there was multiple, and then they put there professional skills to work to fix the problem. Now I have worked with a few contractors on this place but none was more professional and spot on with the plumbing n septic system here. They explained to me in detail what others have installed wrong and talked to me all the way through about my drain issues and which septic tank was actually servicing my place. I would say that all 3 deserve recognition and a raise for what they accomplished today considering the age of this place and the mess they walked into. I would recommend this crew for any project and will use your company for the next phase of my plumbing issues, fixing what others have installed wrong. Thank you guys again. Jerry W.Wendy CordovaWendy Cordova ★★★★★ Recommend by a friend this place is the best for septic we’ve ever experienced. Christopher was awesome today an his partner. Very professional an informative not to mention great personality. Will definitely use them again. 😊.Michael MeshewMichael Meshew ★★★★★ We had a septic emergency late in the evening. We frantically called several septic services but nobody would come help. Luckily, A Advanced was available and sent Andrew to help us. He was kind, patient and highly knowledgeable. He went above our expectations by explaining every step of the process, answered our questions, and was able quickly resolve our issues. In, out, done. I would highly recommend Andrew and A Advanced to anyone needing septic services.Gail MaestasGail Maestas ★★★★★ Cody did a fantastic job digging to, and pumping out my septic tank. Thomas and Eliseo did a beautiful job installing risers and covers. The team at A Advanced are courteous, reliable, and knowledgeable. I will recommend them to everyone from now on.Karen. Lindgren.Karen. Lindgren. ★★★★★ I can’t say enough about Advanced Septic. I called because my septic wasn’t pumping and they came out promptly to help. Came to find out that not only did the pump break but there were rocks blocking the manifold to the drain field. They had it up and running in no time! I’m very appreciative of them all. They’re definitely the people who you want to call! Thank you Kaylee, Pedro and Cody! You are lifesavers. 🙏🙏Shanna PlotnerShanna Plotner ★★★★★ We called A Advanced Services for an emergency septic pump and Cody Letavec the technician showed up promptly as promised. My husband had dug up the tank which saved some time, but Cody was friendly, professional and courteous. Definitely worth every penny spent.Leah HendrickLeah Hendrick ★★★★★ Always excellent customer service from the scheduling team and from the service team. The service team is professional and very friendly. Have had them out a few times over the years and they always are very helpful and get their work done efficiently.Luann KlimaLuann Klima ★★★★★ We were recommended to you from our friends who had extensive work done and they could not have been happier. We agree!Christopher was a really great guy and could not be happier with your service. Anyone who needs anything septic related done, this is the place. I will be happy to recommend your company to anybody who needs their septic serviced as you were recommended to us. It’s hard to find exceptional customer service but Your company has managed to do just that. Shout out to Kayley as well who took my original call and answered my many questions. We appreciate you all.Cybill BellCybill Bell ★★★★★ What a wonderful experience after a horrible one with FLOHAWKS. DON'T EVER USE THEM.They were pleasant and professional, which made it so nice. Arrived EARLY and had my problem fixed in 2.5 hours. Cody was FLAWLESS. He was courteous, informative and efficient. The best part? All done reasonably priced. THANK UUUUUUU 😊John DonaldsonJohn Donaldson ★★★★★ A Advanced were a great choice. Their tech Cody showed up within an hour and was courteous and professional. He went above and beyond and has to work extra hard to get the problematic lids off which were under a low porch so he had to get on his stomach to work on prying the lids off. He cleared the intake clog and the tank didn't actually need to be pumped. I appreciate his great honest service.Unapologetic Human MaleUnapologetic Human Male ★★★★★ Really appreciate them being able to get me scheduled the same day. James was great at answering my questions and advising me for the future. As a technician myself in a different trade I really respect the prices where exactly what I was told and no weird upsales!Angela CastroAngela Castro ★★★★★ I just had my septic system serviced.The Technicians were very professional, nice and focused on there task at hand. The lead Technician explained what was going on and suggested what would be best only once I asked. I feel like I received real good serviceDuncan JonesDuncan Jones ★★★★★ Josiah and Gustavo came out emergency basis as soon SAME DAY at 8pm. Thank you to dispatch who was extremely helpful as well. Transparent pricing, quote up front. Positive attitudes on site, friendly and very communicative with lots of feedback about our septic system condition. In and out in about an hour and back to normal after 100% full septic tank and jetter clean out due to clogged line. They were in no hurry to leave until all systems tested successful and simultaneously and waited for my all clear to leave. Would have them out again in a heartbeat and an A+ experience.

They were very friendly and informative answering all of my questions.I called that morning andthe team got me scheduled same day and kept me updated by text and calls throughout the day until they arrived and took care of our needs early eveningDefinitely would recommend them!Michael TulipMichael Tulip ★★★★★ Great service, Professional. On initial service call they responded same day, drained tanks to identify the issue as pump failure, ordered all part's and scheduled electricians who responded in two days and had new pump installed and operating in less than 2 hours. Excellent service from all involved. I will use them again!!!ChrisChris ★★★★★ We had a great experience with A Advanced Septic Services/team last week. The office people were friendly and prompt. The technicians contacted us within the same day. We are very pleased with the services the technicians provided. A special thank-you to Brian Sorensen, and Andrew Cushman, who worked long hours in the rain to fix the clogs and tree roots in our main drain. They were very thorough and professional. They took great care and explained the work thoroughly to us. The final bill is reasonable. We are very happy with their work and would strongly recommend them to everyone.Leanne PusateriLeanne Pusateri ★★★★★ I had scheduled riser replacement work done on a Monday. They got there early, got the work done, and tried to put the lawn back together the best they could!! 3 days later the septic alarm went off (Thurs night). I contacted the office to get someone out to check the situation Friday and get it fixed so the house wouldn't be out of water for the weekend. Well, 4pm went by, 6pm, 8pm went by. By that time I figured I was screwed. Around 8:30pm I got a call from a technician. They were on there way and about 5 minutes out. Yes, they came to my house just before 9pm, did the work in about 30 minutes and were on their way. I was, and am, so grateful that they did that. Thank you again.Kate HurzelerKate Hurzeler ★★★★★ They came out late in the evening around 7:00 p.m. The technicians were polite and helpful. They showed me how my system works and answered all my questions. Are septic had a leak they were able to fix on the job that night. I'm very grateful for their serviceDoyle CampbellDoyle Campbell ★★★★★ My tank alarm went off on a Sunday morning. Not knowing what the problem was. I started reaching out to septic companies. Many had open 24hrs on there add. A Advanced was the only one out of 6 companies that was VERY professional and quick on coming out. Luis Rodriguez was my technician that came out. He was very professional, polite, and respectful. He walked me threw the steps and throughly explained everything to me. I strongly recommend this company. It is ran like a family owned business and not a big corporate company.J SinclairJ Sinclair ★★★★★ I called multiple companies to have my septic tank pumped. This company was the only one that asked if there was back up into the house. When I said yes they immediately said they will have a person out as soon as possible to take care of the problem.The gentleman (James) called to let me know he was on the way. They sent a text with his picture and a little background on him.I would recommend this company to anyone.Thank you for a great end to a crisis.Robert DenisonRobert Denison ★★★★★ Great service and very good customer service. Both crews that came out were excellent. Our pump went out on a Friday night at 10 pm. Monday the tanks were pumped and Tuesday the pump was replaced and all is good.Edward KnollEdward Knoll ★★★★★ Excellent service, way above average.Rob was most helpful and answeredAll my questions. I give him an A+ forWork ethic and friendly attitude. I highlyRecommend them.Alexander MyersAlexander Myers ★★★★★ Called them at 7pm on thanksgiving day due to my septic system backing up. The person I spoke to was very knowledgeable and professional and explained the rates with me. I received a text message with the technicians photo and a ETA of arrival. The technician arrived that same night and found my filter was clogged and explained everything to me and replaced my septic filter. He didn’t charge me to pump the tanks due to it not being necessary. Replaced my filter and my septic system has been working great since. Additionally the price the technician gave me was lower than what they charged! I would definitely recommend this company! They are very responsive/ professional and fair in price I will definitely be reaching out to them in the future when my septic system needs to be pumped!!!Mike McAfeeMike McAfee ★★★★★ We had an issue we were trying to diagnose as a plumbing or septic problem in our home. We called them and after a few questions and checking a couple things they suggested, it became clear we needed the septic addressed first. They said they could get someone out that day and maybe in the next four hours. Within an hour, someone was there and an hour after that, the problems were resolved and I knew a lot of more about our septic system. I don't leave online reviews often, but the service and expertise we received made we want to let them and others know that this is a good company to call and work with.Matt BarnesMatt Barnes ★★★★★ Scheduling an appointment with A advanced services was quick and easy.Unfortunately they missed their arrival window and we had to reschedule. I understand things come up, especially emergency service calls that may pull a technician away, but they made sure to take care of me for the inconvenience which I really appreciated.Their technician James came out for the next appointment and he was great to work with. Very knowledgeable and communicated everything that was going on with my system.I’ll definitely call A advanced again when future septic needs come up. Thanks again James!FreakFreak ★★★★★ Very easy to work with. I knew what I was to except, payment wise, before the technician showed up. This is the first time I have had septic, and first time servicing. I did not know the location of my tanks but the tech located and dug out the covers before I heard back from my realtor. The tech was very thorough, took pictures and provided me with pointers. I attempted to tip him a little, but he refused…I insisted though! I’m not into smelling my own stench much less others. I’m going to be a repeat customer. Thanks folks!J HirataJ Hirata ★★★★★ Had a new septic installation and removal of the old system. A-advanced knows this process inside and out. Take comfort in knowing there is no job too big or small they can't handle. I would use them again and highly recommend.David ThompsonDavid Thompson ★★★★★ Really great customer service. The worker who came out to my place did so on an emergency call. They had to drive nearly two hours to get to my residence and wound up working late in the dark. They were polite and friendly the entire time and really helped us out. I really appreciate the extra effort they made to solve our issue. Furthermore, they were so pleasant despite the long drive and long hours for an unfortunate situation. I couldn't be more pleased with the service.Thanks so much specifically to Harmen. Serious rock star.Smoochie pooSmoochie poo ★★★★★ I don’t typically take the time to write a review, but this company deserves a raving review. The people that work here are honest, knowledgeable and didn’t try to sell me on things I didn’t need. From beginning to end everything was smooth and stress free. Cody, Ahkeem, and Taylor a huge thank you for all that you did for me! Definitely a customer for life.Rod CassidyRod Cassidy ★★★★★ In June of 2020 A Advanced Septic came out to our place for a Drain Field Rehab. Prior to that service, we had been nervous anytime we had company. Would the system hold up, even though we were careful with extra toilet flushing and showers?The techs arrived right on time, were personable and efficient, and got right to work. Days and weeks after the rehab, we could see that the system was working well.Now in August of 2023, after several family reunions, we continue to be impressed with our well-functioning system.We wholeheartedly recommend A Advanced Septic for excellent communication and effective A+ service!Margo PenaMargo Pena ★★★★★ Andrew was incredibly courteous and professional. This was probably the most thorough cleaning/maintenance service we have had for our septic tank. I really appreciated his recommendations for how to best continue to keep our ~50YO septic system functioning well.Jessica BerryJessica Berry ★★★★★ ATTENTION MANAGEMENT OF A ADVANCED SERVICES!Our technician Christopher Hale was AMAZING! Give this man a raise!We originally scheduled for 2-7 pm today. When I scheduled I had mentioned we were in a rush to get this done due to the selling of our home. This man called me and said ‘hey can I come earlier’. Of course you can! He showed up within the new time frame of 20 - 25 minutes from the time of the phone call. He was super fast at getting everything done! He had to dig in this super hot weather and still was amazing at the end of it! 10/10 would 100% recommend not only this company but also this technician! A Advanced Services you have a great tech here! Great job! And thank you again Chris! You’re a rockstar!Jessica HouckJessica Houck ★★★★★ Matthew and his trainee came to my home today to pump and inspect my system for sale. This is my second service with A Advanced and just as before they were professional and informative. I chose your company a few years back on the recommendation of a neighbor and I am so glad we did. Everything was explained thoroughly before and during service. No unnecessary services or fees were introduced. I would and will continue to use this company mostly because they are honest and that is a quality that I value!Perla OwensPerla Owens ★★★★★ I clicked on the first septic company that came up in my search and I am glad I did. I called in the morning and made an appointment. After going back and forth with my husband telling me we were fine, he cancelled our appointment. He then called back and rescheduled realizing we did need someone to come out. The tech that was supposed to come out had went home because we had cancelled. Luckily Luis was standing there when we called again, and was asked if he could do the job. He agreed. We are very grateful and thankful he did. He came out andwas very informative about our whole system. Luis was very friendly and didn't mind both of us asking him questions. He has a great sense of humor, so it made the whole stinky process more bearable. We want Luis to come back next time we have to have the tank emptied!But I don't want to leave out the gals in the office. They were all very knowledgeable and friendly as well!! Thank you so much for a good experience in a very Sh!!ty situation 😉Mike MattilaMike Mattila ★★★★★ I had advanced Septic come out to my home to solve the problem with my alarm going off on my septic system. The first tech that came out isn't the reason I'm writing this review, he was quick to tell me what was wrong and would talk over the top of me while I was explaining what was happening. When he left he said everything is back to where it should be and I said Ill see you tomorrow because the alarm is going to go off again tomorrow. Sure enough it did I called back and they were quick to send someone out again. Brian Chapin looked at the control box, pulled the cover off of the pump tank and within 30 seconds said, "There's the problem the float has come loose and is floating in the tank" Within about 15 minutes he had the float pole pulled up re-attached the float and even replaced the zip ties on the other floats with metal pipe clamps. He tested the system and what do you know its working perfectly. Brain also pulled the filter and clean it out, checked the solids tank and suggested we get it pumped which we will do. Brian was the Service Tech we are all hoping we get whenever we need any kind of service work performed. He listened to everything I had to say, explained everything he was doing, was well versed in his trade, but most of all I felt completely confident that he was the right man for the job. He even helped me with making sure that I was not billed any additional charges for his work that day. Even though day 1 technician didn't fix the problem, I'm still giving them 5 stars for the way they handled this call. Brian is the technician every company wished they had. Advanced Septic....take care of this man!!!Rich JohnsonRich Johnson ★★★★★ Septic System Replaced: After having a new replacement septic system designed, I sent the design to three different companies, and I have to say that A Advanced Septic & Construction was excellent to work with from the estimation process through the construction and installation. They were very responsive during the estimation process and took the time to walk me through all the options and decisions which I greatly appreciated given the cost of a new system. Likewise, the installation process was great. Good communication and very approachable. The final cost was inline with the estimate plus some unforeseen challenges; however, the final cost met my expectations.Greg BurrowsGreg Burrows ★★★★★ Very happy with this company. Very trustworthy. They are clearly hiring good people and training them well in customer service. Friendly, honest, explained things clearly and offered options without pressure. Will happily use them again and recommend them highly.Carm De La CruzCarm De La Cruz ★★★★★ A Advanced Septic came out promptly, were VERY knowledgeable, implemented a stress test and got us going to sell our house! This was after we paid roughly 4 times for the same test and a “repair” from another septic company that could not give us any hope or options when they failed to find the problem and repair it. Absolutely recommend this company as the first one to go to!!!Our tech, Christopher Hale was great! He broke everything down for us and saves us further sleepless nights!Alex AguilarAlex Aguilar ★★★★★ Sunday! 12:00 AM! Father's Day!Family in town visiting!!Had a septic back-up, called A Advanced Septic. Originally made appointment set for next afternoon, but then they were able to find/send technicians to be at my house within 30 minutes of me calling!!Greatly appreciate the the speedy help Maxi (dispatching) and the guys for taking care of us. Could have been very messy and embarrassing!Thank you A Advanced Septic!Amanda WillardAmanda Willard ★★★★★ A Advanced Services is the best! The customer service is excellent! They scheduled a septic inspection the next day, showed up early by request and the two gentleman were professional, polite, and a wealth of knowledge. I often don’t leave reviews, however this company and its employees deserve the recognition for excellence!McKenzie MillerMcKenzie Miller ★★★★★ Great company to work with! We had to have a routine septic tank inspection required by the county and I had reached out to a few different places. A Advance was quick to contact me back and super helpful answering all my questions. Their pricing is fair and we were able to get a next-day appointment. When the tech arrived, he was friendly, communicative and everything went quick/smooth. We will definitely recommended A Advance Services to anyone and will be using them again when we need our septic pumped.Ryan BishopRyan Bishop ★★★★★ After an alarm in the middle of the night, called our regular plumbing service who directed us to this business. They actually answered on a Sunday said they'd send a technician out that same day. Ran a little later than was originally promised, but it was hailing that day. Tech came out, diagnosed the problem quickly, did some maintenance and upkeep of the septic system, and was done in less than 45 minutes. He was also gracious in answering my questions since septic systems were new to me. Very courteous and professional!Morgan DeHanMorgan DeHan ★★★★★ Awesome customer service, called with a few questions. Was not sure if I was going to need their services but they gladly answered my questions. Called them back once I figured out I did need to have my septic system pumped, they were able to have someone out in less than 2 hours. Josh the service tech came out and was nice and very professional, will definitely be using A Advanced Septic in the future.Jude KrugerJude Kruger ★★★★★ I am so impressed and thankful for the quick job Jeremy did on my shower drain and the cost was more than fair. Having no idea of what was clogging my drain up he knew just what to do and within minutes the problem was solved. I highly recommend A Advanced Septic & Construction, you won't regret it. If I could I'd give them a 10 star rating!!!Angela GoldsmithAngela Goldsmith ★★★★★ We had an alarm on our septic system early in the morning. They came out that day. Figured out the air compressor for the system had died and found an unrelated water leak under the house. The got a new compressor quoted and ordered for us and installed it a few days later. Highly recommend them! All of their people were pleasant and professional. Reasonable pricing too.Carolyn MitchellCarolyn Mitchell ★★★★★ Called for a septic pumping appointment and was able to have one scheduled for later that same day, even on a Saturday! Pricing was competitive to other quotes received, but timeliness and professionalism from A-Advanced is what set them apart from the rest. They showed up, did the job, were kind and conversational. Would highly recommend!!!! The other reviews on here speak truth as well.Andrew JohnsonAndrew Johnson ★★★★★ I called them on a recommendation from a Niehbor. They were able to come to my house same day. Jacob and Luis are extremely professional and found the problem immediately. They walked me through what needed to be repaired and got it done quickly and thoroughly. A Advanced was upfront and clear about pricing which was reasonable. Thanks to Aurora for helping get this visit set up in a timely manner. Happy customer hereJennifer TorresJennifer Torres ★★★★★ The pump went out on our septic system and we had this confirmed on a Friday. We had just had our inspection a few weeks prior and weren’t due for pumping yet for likely another year, but because the pump went out suddenly, we needed pump service on that Friday. The guys that came out, Matt and Justin, they did a very nice job for us and my husband enjoyed chatting with them. They weren’t able to replace the pump then due to not having the part with them, so I called the office and they were able to schedule us for Sunday morning. Joe called to let us know he was on his way and when he arrived, we were so impressed with his manners and positive attitude. He made sure we understood everything he was about to do before getting started, made sure he addressed any questions or concerns we had, and then went right to work. He installed the new pump and did all the necessary testing for us and gladly, our new pump was covered under warranty and we had a really good outcome. When Joe finished our install, he spent a few minutes talking with us about our system and shared a lot of great information with us. It’s clear to us that he is extremely knowledgeable, personable, and goes the extra mile for his customers to feel at ease and have a positive experience while he’s there and to feel really good about the work he performed once he’s gone. Joe is definitely a shining star and deserves to be recognized as such. Also worth nothing, the two individuals who answered the phone when I called in were extremely professional and courteous, particularly the gentleman working that Friday when I called upset that we weren’t able to change the pump the same day. He stayed calm and polite throughout the call, and while I can’t recall his name, I will say, he did a beautiful job of representing the company and also deserves recognition because I wasn’t the easiest person to deal with at that moment (I apologize). Lastly, thank you to Adell for being so kind to us and explaining things so nicely and for doing your very best to make us feel valued and heard.Ben JonesBen Jones ★★★★★ Can't say enough about this company or the technician who serviced my septic. I spoke with Courtney in the office who was very helpful and friendly to get me scheduled for a septic pumping. James came out and couldn't have been more friendly or knowledgeable. They send a picture of the technician with a bio so you know who to expect. He took the time to explain how the system looked and tips on how to maintain it going forward. James was Very professional and fast. I won't go any place else next time I need any sort of septic pumping, inspection or repair. Wonderful experience and I would highly recommend to anyone.Justin MorrowJustin Morrow ★★★★★ Last week our toilets backed up. My wife is pregnant and uses the restroom often. The same day we called we had a service team out addressing the issue. They were very polite and professional and explained the process and what needed to be done to correct the issue. Greatly appreciate their fast response time and very professional approach. Highly recommend this company and their people.Rachel GrimmRachel Grimm ★★★★★ We had Joe out to evaluate our septic tank to see if the issues we were experiencing were serious. Joe was very kind, patient and informative. He was also very careful to make sure everything was closed up before he left so my dogs would be safe. It seems like a little thing but so many contractors have left gates and doors open and unintentionally endangered my beloved pets.Bill LeifBill Leif ★★★★★ Great company to work with!! In the last stages of getting her house ready to sell so she could move into a retirement home, my mom-in-law found she needed a whole new septic system, and a complex one on a very challenging lot. Brian at Rise Septic Design came up with a design and he recommended working with A Advanced. Rob, Tyson, Miranda, Roslyn, and the rest at A Advanced were very helpful, doing not only the installation but handling the title paperwork with the County for a very reasonable cost. A key thing I can say is that there were the typical complications during construction, and Rob and Tyson were very professional in working with me to come up with solutions and keep the job moving. It was a pleasure to work and the whole crew, the system was approved by King Co, and the house is now sold.James “j” McCauleyJames “j” McCauley ★★★★★ From the Saturday evening emergency septic pump, to the drain field evaluation and rehab 10 days later. The technicians, office staff, sales reps and everyone my wife or I spoke to were amazing. Thomas and his coworker who did the Septic pumping were friendly and courteous. Ryan, who did the initial site visit for the Septic rehab answered, or returned, all my calls in a timely manner. Taylor who did a second site visit for mapping out all that needed done. Eliseo and his coworker who worked straight through the day to get the Drainfield rehab completed. Lennie, in the office who spoke to my wife and assured her of everything. A fantastic company, personable and friendly. 10/10 would work with again.Elena FernandezElena Fernandez ★★★★★ I called A advanced septic and construction services because my septic alarm was going off. I called their 24 line at 2am because it was going off at that time and I panicked.They were very nice about telling me that they would send someone that same day in the morning once I told them what was going on (I wasn’t getting backed up water into my house so I knew it was ok)I called other companies that also had a 24 hour number and no one answered even when their website said they were already opened. A-advanced called me back at about 6 am that they had a technician ready and would be on the way. They were very clear about pricing and steps.The technician got here, talked to us and explained everything. I felt very confident and comfortable with their work by this time because they explained everything after an inspection , the technicians were very knowledgeable, Their prices were also very good. They were out of my property very quickly and took care of the problem. I had my septic pumped because I had waited too long to clean out my filter and it could damage more things. I will definitely be recommending A-advanced to my neighbors and family members. Thanks A-advancedKarlee BrimmageKarlee Brimmage ★★★★★ Doug came out to pump my septic tank and he was very friendly very knowledgeable. And he did the job great. But his personality won me over.. this man is amazing and should be told so by his company too. He represented his company in a very positive good way. And I'd recommend this company and most definitely ask for Doug again.Tom ByrnesTom Byrnes ★★★★★ I recently had an issue where my downstairs toilet was backing up. I removed my septic tank lids and saw my solids tank was full - due to my not having the system pumped them out in way too long. I called some septic companies for an emergency cleaning, but all were booked at least a week out. One of the septic companies said A Advanced might be able to come out that day. I called A Advanced at 11:30 AM and they said they could make it out between 2:00 and 7:00. The technician Dillon arrived at 3:15 and after apologizing for what he was about to see, I showed him the disastrous tank. He didn't even blink an eye, although I am sure he wanted to back up the truck and go back to their yard. Dillon went straight to work and after an hour plus of cleaning he had our tanks completely empty. Dillon saved the day. It cost more for the emergency clean out, but it was well worth it. Dillon did a great job and left a clean job site. I really appreciated that A Advanced was able to make it out the same day. So, Thanks Dillon and thanks A Advanced., I would recommend A Advanced to anyone needing a septic cleaning.Marc DivinaMarc Divina ★★★★★ Both John and Ahkeem were professional and also personable. They did a great job at explaining the situation and giving clear precise answers to any questions I had. They were both knowledgeable. They also did a very thorough job in the data available and making sure my contact information was correct. They fixed my issue in a efficient matter. It was a great experience and wouldn’t hesitate to call them back. Five star experience. Thanks guys.Buy AmericanBuy American ★★★★★ A Advanced Septic is great.Scheduling the work was easy. Those who worked the phones were very friendly and knowledgeable. Matthew did a fantastic job on site, though I slowed him down with all my talking, and counting out the cash. (We had some laughs) I wish him well.This is the second time we have hadA Advanced Septic to our home, both techs were top notch. I'd have A Advanced Septic out next time, if I wasn't moving to Florida.Kimberlee KochKimberlee Koch ★★★★★ Septic inspection and Septic pumpFrom the first phone call I was very impressed, I was calling around for pricing but after calling 6 other places, the phone was answered and they were on it.I was recommended to them by calling Hart, Good call! Thank you!The person that did our work knew his stuff! Much appreciated, he was very professional and did what he needed to do to get his work done ✔Happy Friday.... we do need other work, dang it but also good to know. We will be working with you again soon. Thanks again KimTara HTara H ★★★★★ Really professional and incredibly helpful customer service.We called around for quotes to pump our septic system, I was walked through the process and all the fees. No ‘hidden” charges and was even told about a current coupon they had going. I actually called two other companies including who we had used before but was drawn back to Advanced, how nice they were, how quick they could fit us in and how comparable to other companies they were.Service techs came out on time after a phone call and text giving us a heads up they were on their way and WHO would be showing up. While pumping the technician let us know our septic was actually a 2-chamber system, that we only had uncovered one lid and asked if we knew where the other access lid was (even offered to dig for it but since we weren’t sure and they do charge to dig we declined) and told us how to find out more about our system.We were a little skeptical since we had the system pumped 6 years ago and that company never said a word. After digging through Pierce County records we found it WAS a 2 chamber system, where the lid was and called Advanced back to pump the other side. When I called I barely had to say anything, just who I was and they brought up all previous notes and knew what I was calling about.Since we had already paid for septic pumping they only charged us a service call and pumping per gallon! The other company six years ago didn’t even notice and didn’t pump both sides! We could have had a major problem in a few years and this was all avoided by Advanced's attention to detail. We sure appreciate it and will definitely only call them in the future.Rodger WrightRodger Wright ★★★★★ Emailed company for a bid like at 7:30 at night and by 8 that night Adam called me and gave me a straight forward bid. I was digging up my own lids to save money and he was more than helpful in directing me where to dig and said not to hesitate if I needed and further information. Scheduled a routine septic tank pump out for the following Monday. Sheldon & Dillon called me 30 minutes before arrival and gave me a heads up they were on their way. These guys went right to work and got the job done. True professionals. Would not hesitate to use this company again.Catherine BudingerCatherine Budinger ★★★★★ Jeremy was very respectful, responsive and professional. He spent a lot of energy diagnosing the problem and worked hard to find a solution. We appreciate his attention to safety and that he cleaned up after finishing. He made sure his charges were fair and not overwhelming, explaining everything to us clearly. Definitely will call him if we have any other issues in this future.Christopher WimsattChristopher Wimsatt ★★★★★ We’ve had nothing but a positive experience with these folks over the last couple of years. Everyone ranging from the phone operators to the on-site service guys have been totally professional and personable. A really cool feature they provide is a text message with the name and picture of the service technician who will be providing the service for you.Definitely recommend them.Adrianna HuttonAdrianna Hutton ★★★★★ A Advanced Septic was referred to us by our realtor to perform the essential pumping and inspection required by our county. Adam with Advanced was very responsive with the first interaction and was quick to give us a quote. Their pricing was very reasonable and was much less compared to others. Adam was patient with the process we had to go through with payment and was willing to jump on a call whenever we had questions. Our Technician was on time the day of service was quick and even let us know how much digging would be and let my husband help out to save us a little money. Overall I would recommend A Advanced Septic to anyone.Barbara BitettoBarbara Bitetto ★★★★★ We asked for an estimate to replace a sewer pipe at our home.Ray BrassardRay Brassard ★★★★★ A Advanced Septic was able to schedule the job for a quick completion, way faster than the other septic companies I called. Sid E. and Brandon showed up and worked efficiently on a pretty difficult locate and dig out job during the heat of the day. They busted their butt to get the job done as quick and safe as possible. Sid did a great job of keeping me updated on the process and there were no surprises when the job was done. I highly recommend Sid, Brandon, and A Advanced for all of your septic needs.js_loader
