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 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.

Cliff Thorn's crew were exceptional. We were impressed with their professionalism and speed. They did trim work around all our floors and doors and had beautiful suggestions. It dressed up our house a lot and saved us so much time and effort to use their services. We will definitely use them again for future home remodeling.

CTC came and installed LVP flooring throughout my entire house. I knew that it was a very large job and I was very confident that they would be able to handle it, My expectations were exceeded with the outcome! The staff at CTC are extremely friendly and easy to work with. Thank You Cliff Thorn Construction for everything that you do and for my beautiful floors!

CTC did a great job with a recent roof repair at my home. Job was done quickly and jobsite was completely clean, once the work was done.

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 love my mom and she is a self confessed persnikety consumer.: (per·snick·et·y; pərˈsnikədē/requiring a particularly precise or careful approach.) Mom had a flood in her basement... CTC construction came to the rescue. Cliff and his team did a fantastic job and delighted one tough customer, my mom. Thank you for helping my mom and doing a great job on the repair and remodel. The basement is now mom's favorite room in the house.
