CTC came in and did a small-medium size remodel in my rental. They didn’t play the change order game and they stayed within budget. They will be my go to contractor now, wish I would have figured this out a little sooner.

I had a problem with the clear coat finish peeling on the exposed beams at my residence. I called CTC for help. Not only did they refinish the beams in a timely manner, they went back to the original clear coat manufacturer and asked for an inspection. The manufacturer determined that the wrong product was used originally and that they would cover the cost of the new product at NO charge. On top of that, CTC came up with an affordable solution to protect the top of the beams into the future. That's what I call exceptional service!
