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.

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 Jeff and Connor had the difficult job of demo of the glass and tile shower and the outdated flooring, a little loud, of course, but done in only one day and not a bit of trash left behind.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

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.

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!
