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.

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.

The entire CTC team is a pleasure to work with and their work stands out because of their genuine care for the customer and craftsmanship put into the projects they work on. Would recommend them any day!

I had a problem with the clear coat finish peeling on the exposed beams at my residence. I called CTC for help. Not only did they refinish the beams in a timely manner, they went back to the original clear coat manufacturer and asked for an inspection. The manufacturer determined that the wrong product was used originally and that they would cover the cost of the new product at NO charge. On top of that, CTC came up with an affordable solution to protect the top of the beams into the future. That's what I call exceptional service!

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.

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.

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.

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!

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.

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.
