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.

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!

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.

Triston is a pleasure to work with. Well organized. I had the pleasure of working with Triston in his role as Construction Superintendent, and I can confidently say he brought a high level of professionalism, leadership and attention to detail to every phase of the project Triston consistently demonstrated strong project management skills, ensuring work stayed on schedule and met quality standards, even under tight deadlines and complex conditions. His ability to coordinate subcontractors, manage crews and maintain clear communications across all levels of the job site played a key role in keeping operations running smoothly. What stood out most was Triston pro active approach to problem-solving. He didn’t just wait for issues to arise-he anticipated them, planned accordingly at the forefront. His deep understanding of construction processes and codes made his a reliable point of contact for both the field team and upper management. Triston leads by example, sets a high standard, and earns the respect of everyone on-site. I would highly recommend him for any role requiring strong leadership, technical expertise, commitment to excellence in field.
