“They arrived on time. They worked efficiently but faster than I imagined. They even made it look like I got two new awning windows in the basement by wrapping the exterior of both. Every window looks great! The supervisor was really nice. He even fixed an awning over one of the upstairs windows. Thank you so much!”

“We were very pleased with the communication of every step. Window Nation made this a very easy process from Nowell working within our budget, having the windows measured or window way ahead of schedule and installed weeks before their estimated time. Everyone was on time, respectful of our hour and was very efficient and professional at their job.”

“I had to go through the bad experience and complain for it to get fixed, so no, I wouldn't recommend that to others. It was also difficult to be "heard" by the people I was complaining to. It felt that they could talk down to me and get away with it because I myself am not a window installer. They did end up correcting issues, and getting me the product I wanted, but it was only after damage to my home and complaints that it got corrected.”

“The finance department keeps hounding me. I could have paid for amount in full, but they offered me a 6 month cash payment option. I probably will not pay in full until they come back and fix the rotted out window frames.”

“The contractors did good work. They didn't really explain much, just showed up, knocked out the work, and left. They were mostly clean, but I found some trash and construction debris around my property afterwards. I was more disappointed that over half my windows had some kind of manufacturing defect that wasn't obvious at first, but noticeable upon closer inspection. Scratches or blemishes between panes and ripped screens, plus one window is difficult to close. I will work through the warranty process but 50% is a pretty bad success rate.”
