I am putting my house on the market and have an old gravity flow septic system that had an usual design. I tried contacting other services, but they kept coming up with delays. Finally, I found James, and I'm soooo glad I did.
Within two days of contacting him, he called and came out; remarkably friendly and personable AND he started work that very day, locating my tank inspection covers that required a great deal of digging. During the entire time, he was teaching me all sorts of things about sanitation systems, tree roots, soils, etc.
I had expected that getting this old system up to standards was going to be vastly expensive, but James explained to me what I needed, and what I didn't. He really loves his work, and he came back and installed risers and a new Distribution box in circumstances that were above and beyond the average system, with no complaints at all. In fact, he seemed to enjoy the challenge. He never found any of my questions annoying or unanswerable. He got the system fixed in a short period of time for a very, very reasonable cost. If it was possible to give him six or seven stars, he'd get them. Great work, very satisfied.
