If we could give them a rating of 6 stars we would! Over the past 5 years we have had Cliff Thorn Const. do 3 major remodels in our home, our living room, kitchen and laundry/bathroom. Every job was done perfectly! They were timely in the work and did an excellent job with minimal inconvenience to us. The living room was our first project. After about 3 years we noticed our carpet had some bumps in it. We called Cliff and they immediately came out to assess the problem determining it needed to be restretched. Within 1 week they had someone come out, at no charge, and restretch the carpet. The gentleman that did the work asked us if we realized how rare that was after that amount of time to have the construction company stand behind their work and not charge us. Thank you Cliff and all of your staff.

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.

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.

I had a utility sink/dog-wash station installed in my laundry room. I LOVE IT!! CTC did a super job! Everyone was so nice and helpful. I couldn’t have asked for a better experience. Jake worked with me to stay within my budget, Amy helped me pick out tile and James was always there checking in to see how the progress was going. The sub contractors were all very respectful when they came in and out of the house. They knew what they were doing. They were efficient, got in and out quickly and everthing works and looks great!
