KDT Construction, Ltd.
Green Building Companies in Denver
Average rating: 5 out of 5 starsOctober 18, 2025
“I recently hired KDT Construction to remodel my home after my prior contractor was virtually incommunicado and two months late from even starting. I could not be happier with the results from KDT. From start to finish, the team was professional, reliable, and incredibly skilled. They listened carefully to my ideas, offered helpful suggestions, and delivered exactly what I envisioned—on time and within budget. Their attention to detail and craftsmanship truly stand out. Every aspect of the remodel, from the design to the finishing touches, reflects quality and care. The crew was respectful of my home, kept the workspace clean, and communicated clearly throughout the process. It’s rare to find a contractor who combines such professionalism with genuine pride in their work. I highly recommend KDT Construction to anyone looking for a trustworthy contractor who delivers beautiful results. I’ll definitely be turning to them again for future projects.”

“We have many good things to say about Jeremy and his crew. He has done work on three of our homes now. This year he completed a garage addition with a remodel of the existing garage into livable space. The results are fantastic and better then we imagined. This also included a new covered deck on the back side of the garage to give us three season use. One of the many things we appreciate about Jeremy and his crew and the subcontractors (electrician, excavator, tile) he uses is how meticulous they all are. We started our project during the covid shut down This added a new level of staying on time and on budget. With the other properties he has worked on for us, the work was completed as expected. As far as staying on budget, he was on budget with the items that I didn’t change along the way. The few times that it was clear that there would be an increase in cost from the estimate, he addressed it as soon as he knew there was a cost change. Most times the changes were based on the labor for the finish materials I selected. For this project I didn’t select the finish materials until after the project started, specifically the type of tile for the new interior space and the decorative tile for the exterior of the new garage. In these cases we were happy to pay the increase in labor costs. There were also cost changes to building materials, which was part of the supply chain issues with material shortages. Jeremy and his crew were most respectful of the fact that we continued to live in our home during construction and the covid quarantine. We had three adults working from home and communication was great to let us know when any of the subcontractors needed to get into our living and working space and how much time they would need. We can enthusiastically recommend Jeremy without reservation.”
Cillessen Construction Company
Green Building Companies in Denver
Average rating: 5 out of 5 starsJanuary 31, 2019
“We hired Cillessen Construction to install windows and siding for our home addition in Evergreen, Colorado. The job required experienced and knowledgeable professionals, as the house is 30 feet high on the west side and has numerous angles and slopes. Heath and his crew accomplished each task in the installation with expertise. They offered many insights on not only what would look nice, but what would be practical as well. We enjoyed working with Heath and his highly professional and courteous crew.”
