I met Walt recently, at an impromptu stop for re-fueling. He was kind and greeted me very well. It was a very nice gesture and I just want to thank him for that. If everyone at the company is like that, I will be very happy to establish work with them. All the very best!

Marc was very helpful as he came out an looked at what we wanted done but he wasn't able to do it in our time frame so he was very helpful at helping us find someone that could do the project in our time frame. We was very grateful for all the help an suggestions. We will definitely check back if we decide to do more. Thanks again Marc!!

CTC converted the master bathroom shower to zero clearance. I was nervous about the project and has already turned down a separate contractor because they made me feel uneasy about how it would get done. CTC impressed me from the beginning with confidence and professionalism. They didn’t let me down. The project went perfect and everything turned out just the way they said. It was even done early. I will definitely use them again for the next project.

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!

CTC just finished my home addition and bathroom remodel. We had a couple special order items we couldn’t decide on that delayed the project and CTC had a very collaborative “can do attitude” the whole way through the project. We were happy to have their guidance through the duration of our project! Highly recommend.

We have worked with CTC for 3 years now, specifically Mike Thorn. Their team starting with Mike, down to the project managers, superintendents, and construction crews are responsive, thorough, and a pleasure to work with. This is a family owned business that will get the job done right. Recommend this company for any residential remodels, new construction, commercial TI's or commercial new builds.
