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.

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.

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 Jeff and Connor had the difficult job of demo of the glass and tile shower and the outdated flooring, a little loud, of course, but done in only one day and not a bit of trash left behind.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 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!

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.

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.

Working with Cliff Thorn Construction has been a fun experience. We primary worked with Stephanie, and her communication was top notch -she is direct with how we can handle drop off and pick up and what needs to be done. She is professional, friendly, and reliable, which has made the whole process of creating embroidery shirts for the company truly fun. The professionalism extends to everyone at the company, everyone is so nice and helpful. We highly recommend Cliff Thorn Construction and will definitely be working with them from now on.
