"Matt did an excellent work and I am very happy! It’s been at least two weeks and no issue from my water heater - no leaks. He was very responsive and he cleaned his work. It is not easy to find someone who can do both in replacing the damaged walls and installing the water heater. I hesitated at first how much he was charging for it was very affordable. It wasn’t a scam and he did an excellent work."

"US Trench less was referred to me through a friend. I called US Trench less and explained the situation I had in my backyard. US Trench less came out the next day and ran the diagnostic TV scope where we were able to see how bad of shape my pipes were in. US Trench less was able to come out and start working the very next day. The entire job was done in less than 4 days which was amazing considering how quickly they began working. US Trench less was honest, very trustworthy, knowledgeable, and prompt with my situation. I would highly recommend their work!"
