"Was able to locate lids for septic tank and dug them up (3). Very friendly gentleman. I will be having him check and open the drain field so my septic system will work like it is supposed to. Would highly recommend him for any problems that you may have with your septic system"

"You need to hire A Advanced Septic if you need work done! So these are the specifics: 12" Riser and lid installed, 24" Riser and lid installed, tank repealed which included digging down and around the septic tank, exposing the tank below line penetrations, per and clean tank surface, sealed inlet and outlet penetration into tank, applied Jet-set to tank bottom and seam, remove and re-seal riser assemblies, wrap exterior and top of tank with moist barrier, and then back-filled the whole area. And this is the rest of the story: My husband just died in December 2020. Of course everything went wrong after that. We had heavy rains and my sump pump overflowed into the basement - our living area. It seems that the previous owner did NOT direct the drain for the sump pump into the septic tank - and we still have to find out where it drains to. But anyway, the floor flooded (laminate flooring), all the rugs were damaged, the walls soaked up water, and all of that has to be fixed. While the plumber was working on the sump pump he looked at the septic tank and found that it needed resealing - because the previous owner did a do-it-yourself- fix with a cheap septic pump and illegal modifications. The septic tank had to be pumped PLUS the septic pump had to be replaced - to the tune of $3,000.00. But because the tank had to be resealed so it wouldn't happen again, they could not guarantee the pump if there were more heavy rains before the re-sealing was done. Bob Larson Plumbing, LLC called A Advanced Septic to help me and they sent Travis out to look at the situation and write up an estimate; the following week they were here fixing everything. They can't fix my basement floor or walls or correct where to drain the sump pump, but it is such a relief to know that the septic tank is not going to fail the next time it rains! The technicians were knowledgeable, timely, efficient and friendly. I am so grateful for the work they did, especially at a very high stress time for me having just lost my husband and then the flood in the house and then the septic tank pump not working."

"They quickly assessed the situation, gave a reasonable quote, and were very proficient and professional. My condo unit was under contract and a water leak caused by another unit needed to be repaired asap and they did it. Also kept me well informed."

"We got our working tank water heater replaced, it was 14 years old so about end of life. Due to COVID they asked for photos via text message, gave quote for exact product, suggested that expansion tank is on wrong side (we never knew), came on time, got the products, fixed the expansion tank and were done in less than 2 hours. Asked to clear the garage, maintained social distance, job perfectly done."

"Very professional and quick. Came out next day and gave estimate. Then found right tank and installed following day. Very good job of explaining, cleaning up. Always arrived when they said they would. Excellent communication from office and worker. Expensive, at the high end of Google range of estimate, but we were leaking and the timeliness mitigates cost."
