Do not go with this contractor unless you want to replace your leech field, he replaced my moms rental property 2 years ago, and now the system is backing up, so they called him out and he said we need another new leech field... again.
We used him last year, and he told me I needed a new leech field, well we tried to get back ahold of him for 2 weeks. Finally got ahold of him, the system worked fine for about 2 months and it kept backing up. We could not get ahold of him for another week, we had to use him for warranty purposes, so we finally got ahold of him and he kept rescheduling, so we were out of a sewer system until he came (which was a week).

Bottom line, don’t use him
