George C., Summit County, CO
When I noticed that the double pane windows in my townhome of 20 years were failing, and my furnace was working overtime to maintain the desired temperature within my home, I decided it was time to replace them. After looking at a number of contractors, I decided to do business with Gregory Door and Window. They provided expert guidance in helping me select Andersen E Series windows and sliding glass doors. They handled the installation of the windows and doors in a very professional manner. I have found the Andersen E series to be very efficient. They help reduce my utility bill by as much as 30 percent.
