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!

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 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.

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.

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.

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!

AmyLynne and Jake were very impressive from the very beginning. They explained the process in detail and were accommodating to our schedule. Jeff and Connor had the difficult job of demo of the glass and tile shower and the outdated flooring, a little loud, of course, but done in only one day and not a bit of trash left behind. Jeff continued with sheet rock, texture, painting, and flooring. We could not have been happier with Nathan and Guillermo and their work with the cultured marble. Dave, Ethan and Julian were awesome plumbers. James and then Kirk were always checking on progress and making sure materials were where and when they were needed. The floor-to-ceiling sheeting to protect the side room and counters was especially appreciated. The floor from outside to the work site was also protected. There was one unanticipated "hiccup" for the need for a new water shut off valve that was handled very quickly and professionally. This project was not only completed on time but ahead of schedule. We were very pleased with the process and the final result. There was not one single thing that we needed to do. Our bathroom was clean and move-in ready. Every CTC employee and sub-contractor involved with our project was a joy to work with.

I can't say enough about Cliff Thorn Construction. They came and did some renovations in our home. Not only was their work amazing, but they CLEANED UP after themselves and all the gentlemen that came in and out with the different aspects of the job were so nice and respectful. I will only use them for any future reconstruction or construction. Thanks Cliff for your helpfulness and for your team.
