"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."
