    This has been one of the easiest most painless fixes my house has had. Matt is running a tight shift and does wonderful work also offered an extremely cheap cheaper option than anybody else even presented to us.

    I would not refer this company for anything. He came out bid a job and half ass did the job. Didn’t even complete the job and told us we had to pay him more money to complete a job he was already paid to do. As I look at his reviews he seems to have a track record of this. He will be hearing from my attorney.

    After struggling with septic tank issues, and multiple other flakey providers, Matr came to the rescue. He came to assess the situation, and immediately seemed knowledgeable about the root cause of the issue rather than the other vague responses we had be told by other people with other companies. Within the week or so he was able to come out and install the fix that we needed. It has been about a month now and we have not had any issues at all.

    Update 8/25/25 Had another more reputable company come out and do what this guy neglected to do during install...ANCHOR IT. Cheaper is never better but in this case 20 grand wasn't enough to insure a proper installation. Buyer beware. Paid over 20 grand for a brand new system and not even a year later it has come out of the ground and the owner refuses to fix it. Talked to another septic service and the said it should have been anchored down to prevent it from coming out of the ground. The owner is very argumentative offering only excuses and blaming the property owner for the situation.
