Windows and installation great; No receipt, No written copy of the lifetime guarantee; no written product brand or composition.

Air is coming in around my window. It needs to be resealed.

They look great and seem to work very well

I am 100% totally satisfied with my Window Nation windows. I would highly recommend Window Nation to any potential homeowner that may be in the planning stages for replacement windows.

Installers worked well together and explained when we had questions.

the grids in the windows do not line up with each pane. there were large spaces that needed to be filled in on a few of the windows. Giving me the impression of lack of quality from measuring to construction and installation. Not correcting the large gapes and only covering them up shows lack of concern for quality and commitment.

I would absolutely recommend this company to anyone even my own family!! They are outstanding!!

The installer said they were going to replace a window. Have not heard back yet.

Sales process

It has been a lengthy process with a few hiccups, however my windows are in an I am enjoying them.

Installation crew was very professional

Window Nation was very efficient and knowledgeable. It is early, but it appears that they did a good job.

Quality and salesmanship detail

I would highly recommend window nation Greenville to anyone looking to replace the windows in their home or office. I am very satisfied with my whole process with window nation Greenville.

The installers were very professional and the job was done in a timely manner.

Punctual and did a very nice job

We're completely 100% satisfied with Window Nation, even though we weren't sure about it. We were a little hesitant. However, once everything was explained to us and we settled on the deal, we were extremely happy.

Window Nation took a lot of time and care, and they made sure that they left the site clean and no mistakes.

I would recommend them to a friend because they were very professional.

They came when they promised and they delivered quality windows and installation. After they were done with the installation they made sure that they left my home clear of anything that may have fallen onto the ground and floors during the process of replacing the old windows with absolutely perfect windows as promised.

I am likely to recommend Window Nation - Greenville, SC to a friend because they did a wonderful job except right at the end of working back and forth. One worker started while the other was supposed to finish but I got one window that wasn't done how it was supposed to be done. I called Window Nation and spoke with somebody and they were supposed to have someone come out and fix it.

Get service from them ! They always showed on time . The crew we had was very nice and friendly! Answered all the questions we had. Did a great job on all of the cleaning after job was completed

The sales rep and installers were very polite and professional. When we had questions - it seemed that "upper management" gave a "stock answer" through the sales person and wrote us off. It took us not paying our bill to get further attention. I just wanted to talk to someone knowledgeable - I was sending pictures so figured they could talk to us about what we were seeing.

Window Nation is trying to screw us out of a screen for one of our windows. It's a double slider window, and they're saying we're only contracted for one screen. ARE YOU KIDDING ME??!!??!?!?!?

Damage done by installers,not addressed by the company.
