Colorado Window Source Reviews

"It has been about 8 years and we are still very happy with the quality of the windows. They have lowered our cooling costs dramatically in the summer months and have lowered our heating bills by about 20% ( could have been more if we had all 27 windows replaced) in the winter. When we close our windows, our house is very quite and comfortable. I have recommended Colorado Window Source to a few friends who used them to replace their windows in Denver. Colorado Window Source sent me a $200 check to say thanks for the referrals. I highly recommend Colorado Window Source to my friends and people that I meet who mention they need replacement windows."

"Good Customer Service, prompt service, good personal attitude."

"Best Windows, best price for what we get & Great Installers!"

"The rep and installers were very warm and professional. We enjoyed working with them and plan on replacing the rest of our windows with Colorado Window Source."

"Excellent response, updates on service time to expect person, very professional. Very pleased with emergency call out."

"Colorado window source put in all new windows and patio doors on my house and I love them!!!! The whole process was easy. Chris came out and gave us a great price, the they came and measured and then installed them perfectly. Could not be happier with them. I would HIGHLY recommend them for anything!"

"Excellent company to work with. Honest, timely and cleaned up afterwards.  Colorado Window Source had the best price for the product and the team was great to work with-from the initial salesman, Steve, to the installer, Jim, and his crew. I would recommend this company."

"If you need windows, call these guys. Colorado Window Source gave me a good deal on the windows. The price was right, they were on time, and they did a great job."
