Window Replacement Frederick, CO
Frederick • Windows • Siding • Doors

Replacement Windows in Frederick.
Built for Prairie Wind.

In Frederick, open-sky exposure means stronger wind, intense sun, and hail season that can test older seals and exterior materials sooner than expected. Your windows, siding, and doors should work together as a tight exterior envelope that reduces air leakage, improves indoor comfort, and helps protect your home during wind-driven storms. If you’re dealing with drafts, uneven temperatures, or skyrocketing utility bills, upgrading your exterior systems can deliver noticeable comfort and long-term efficiency.

Windows for America was a great company to work with. If you haven't experienced a window sales event in your home, get ready - window salesmen are like used car salesmen on steroids. However, from that point on, the company was fantastic. My wife had some anxiety about letting people into our house for two weeks during the installation process, but both installers, Jeff and Aaron, were true craftsmen and gentlemen. They never left an opening unfinished and installed all windows before they went to lunch or even took a break. Additionally, they cleaned up after themselves each day. I never found a piece of aluminum or a screw left behind. We had over 30 Edison windows installed, and they are beautiful. Although there was a miscommunication over some patio windows, Matt and the office staff were able to provide a very fair solution. These guys took great care of our home. I highly recommend New Windows for America. Additionally, we live on a golf course and lost a casement window during a high school tournament. Within 4 weeks, Sheila ordered the replacement window and Jeremiah had it installed. Thanks for your amazing service

Three months ago, we replaced 23 windows. The salesman explained the process thoroughly in a way that was easy to understand.The windows were installed without marking or damaging any of our trim! Two days ago, our furnace needed repair and we were without heat for over 12 hours. It just happened to be on a day where the outside temperature fell to 34°. Even though we went overnight with no heat, it was 60° in our home the next morning, due to the great quality of the windows! And did I mention that they look beautiful as well!!!
