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.

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.

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 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!

Great company. Did siding work, door replacements, trim and gutters. All were done on time, on budget with great communication through the entire process. Will be using this company again for further renovations to my property.

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.
