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.

I've been dealing with CTC and other General Contractors from Yakima to Spokane for over 15 years. I'm a subcontractor that has dealt with the positives and negatives with just about every GC around. CTC has been top notch in all areas.

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.

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.

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 Jeff and Connor had the difficult job of demo of the glass and tile shower and the outdated flooring, a little loud, of course, but done in only one day and not a bit of trash left behind.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

We had our shower remodeled from tub insert to full tiled walk-in shower with glass door. CTC was the only company to reply to our inquiries. They were great to work with. We had a rough idea on cost before we started and CTC roughly matched that price. We did have a change due to a plumbing issue but everything stayed on schedule. Whole project was done in less than 2 weeks (minus the glass) . CTC was great at communication, through thier builder app. I greatly appreciated the builder/customer expectations form as part of the contract. I even got Christmas cookies when I dropped off one of the checks.

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 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!
