I have had an opportunity to use Colorado Rockies Windows and Doors to install a French Door and 2 sliding windows in my home. They did a great job on the project. They were prompt and efficient and the Marvin windows and door they installed are excellent. I had one minor interior trim issue and immediately came back out and fixed the problem. Buddy LaFemina is an excellent owner who does what he says, when he says he will do it.

Buddy was the consummate window professional! I had been talking to several window replacement companies including Renewal by Anderson and ran across Colorado Rockies Windows & Doors' ad in the Summit Daily. I had grown frustrated with the lack of follow-through with the other window companies and our winter was coming with snow actually coming in last year through one of my old windows! So time was of the essence. I phoned Buddy who gave me the option to send in my approximate window measurements to get an initial feel for costs. He then came by and walked me through the colors, options, brands

We replaced 46 windows & 2 doors with Marvin Ultimate windows on a very difficult site overhanging a cliff. We needed to use pump-jack scaffolding and a 75 ton crane because of the size of some of the windows and the difficulty of access, and despite the real installation challenges, the installation team did a great job and always maintained a super positive can-do attitude. Also, the initial recommendations by Buddy were spot on in terms of new configurations, he really knows his stuff. I highly recommend this team, they are thoroughly professional and provided a quality installation at fair
