“They did a good job, and they were efficient in coming. Also, they cleaned up after they finished doing the process. I was pleased, and I didn't have to say anything to them.”

“I asked for copies of all my documents and I haven’t received them. Customers service needs to be improved.”

“We recently had two sliding patio doors installed but have reported several issues to customer service. First the door handles that were installed were not the colored we ordered. We order the Oil rubbed bronze handles and one door was installed with a silver handle while the other was installed with a black handle. After going back and forth with the customer representative they have ordered the correct handles but will not be shipped until 11/25/25. In addition, the lower patio door was missing outside plugs to cover the screws. This same door is also extremely hard to lock, and we are unable to use for fear of not getting it to lock again. Finally, the caulk that completed around the door was done poorly and needs to redone. We have supplied pictures to WN Representative.”

“The patio door we received was shorter than the frame. When we contacted customer service, they tried to convince us that this was normal. It was not what we were promised. We were supposed to get a custom door that fits the frame. We did not get the exact fit.”

“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.”
