Still Windows

Average rating: 5 out of 5 starsAugust 12, 2022
“This was one of the most pleasant experience I have had with a company in many years. I reached out to this company for window installing service. I met with the representative David he came over listened to what I needed, he made some suggestions. He gave me a commitment as to when the work could be done, we agreed . The team showed up introduced themselves - they looked over the situation and got right after it. They had "Drop Cloths" - All kinds of other coverings to protect my furniture -floor- These gentleman installed the windows quickly in a professional manner. They cleaned up all their leftovers. The windows look better than I expected. I'm impressed. Awesome job Thanks guys”

Alpen High Performance Products
Custom Window Companies in Thornton
Average rating: 5 out of 5 starsMay 26, 2016
“Alpen provides outstanding performance / value. Alpen's windows make a significant difference to the building envelope - and comfort for the occupants. While you can save energy (operating costs) by using Alpen's windows and doors, the comfort afforded is the reason to purchase them. Note also the sound ratings are also exceptional. If you live in a noisy area (traffic, airport, train tracks, etc), Alpen windows will significantly reduce the noise levels inside the building. And finally, the fiberglass frames are exceptional for longevity/durability and low maintenance.”

Gravina's Window Center of Littleton
Custom Window Companies in Thornton
Average rating: 5 out of 5 starsJune 18, 2015
“This is the second window-replacement project Gravina's Window Center has completed for me. The first was in 2009 and based on my total satisfaction with that job I used them again earlier this year for the remaining windows in my home. Every person at Gravina's was without fail extremely professional, friendly, competent, respectful and very careful inside my home during the installation. I particularly enjoyed working with a local family-owned business. I recommend Gravina's Window Center without reservation to anyone seeking high quality windows, flawless installation and top-notch service.”
Mountain View Window & Door

Average rating: 5 out of 5 starsMarch 29, 2013
“I am a contractor and purchased quality windows from Mountain View Window and Door company and hired them to install for my remodel project. They are a new supplier for me and are very friendly and timely in their quotes and ordering, as well as providing a professional and friendly installation team. I also purchased interior doors from them which I had my own trim team install. I will work with them on upcoming orders in the near future.”
