"He did an excellent job replacing our septic tank. He solved a difficult problem with a huge boulder that was blocking the move of the tank. Also was very careful not to damage the rest of the yard during installation. Overall, job well done. Quality job at a fair price."

"DEFINITELY RECOMMEND! Joe and Denise are very nice and easy to talk to. They listen to what you need and made sure you understand the plan before they do anything. We asked for extra work and are very accommodating. With regards to work itself, they took their time to do it right. With us, we had a last minute change of septic tank size and Joe was so nice to accomodate us. They did an excellent job with our septic system and will definitely recommend them. We also feel like we gain a friend!"

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."
