Installment of home replacement windows
From first contacting window company, received very quick response, and was able to schedule a quote with salesperson. Company continued to update by email or text message with status of installation date. I was able to contact installer department to schedule a date that I would be available. Greatly appreciate this! Installation day was wonderful - due to installers within timeline window, explained the process before starting, and agreed to complete one room first, so that my dogs would be comfortable. As they completed installing the first window, they asked me if I would like to observe. They completed all installed replacement windows in the time frame that they had given to me. They also took time out to clean up any mess from review old and installing new windows. Plus, they worked me thru - opening, closing, locking, all parts of windows, screens. At this point I am very pleased with the windows and service.

Install was done poorly first visit
Install was done poorly first visit. Had to have service techs come out 2 more times to fix issues. Felt job was rushed and didn’t give the attention and time that they should have. Would not recommend Window Nation for a sliding glass back door.

Best deal on high quality product and service
For our family this was the best deal providing a major upgrade of our old home with very high quality windows. I really appreciated how the cost of the project was efficiently and honestly determined. A selling point for us was that the installers would replace any old bad wood that needed to be replaced, and on that they delivered. The installation was surprisingly quick, and done by courteous professionals doing beautiful work.
