They came on time
They came on time, took a little longer then I was told, but they cleaned everything up, and they even blew all the leaves off my back roof, they didn't have to do that. Good work.

Window Screens finally delivered
Had 2 windows, a sliding glass door, and a bow window installed. Received a fair price, waited just 2 months for delivery, excellent craftsmanship during installation, but the 2 screens for the bow window were not included. Waited 2 more months for the screens to be delivered. It's now November and 35 degrees outside, so the screens aren't really usable until spring. Otherwise friendly Window Nation employees during the whole process. Would of been 5 stars if not for the missing screens!

Bay window got put in with chip in wood I ask to talk to project manager and crew told me he was coming.so I waited and waited. Called window nation as the job was almost complete and they said he would be coming. Crew completed job ,manager never came. Came time to sign for project completion and still no manager. Crew spoke a different language so was hard to communicate with them. They end up using wood glue to fill in the wood that was damaged. Not sure I'd recommend this company at this point

My experience was very positive from the get go starting with Franks (sales) who provided an excellent presentation for me while answering my many questions and addressing my concerns even after “closing the deal” I really appreciate his obvious experience and knowledge of product and manner of explaining the whole process.
Quinn also was extremely helpful with customer service he provided for me by going over the financial details that I needed help with.
Lastly, the work crew was absolutely fantastic with their workmanship as well as their professional, respectful communication installing the windows in less than 6 hours.
I sincerely thank all who were involved in this process

An extremely responsive, hassle free and professional company with great people and great products
We were only looking to replace 4 windows and never felt pressured to purchase more. Everyone we dealt with, from getting the initial estimate to the final measurements to the installation, were extremely responsive and friendly. Whether through a phone call, email or text communications, we received replies immediately and all communications were clear. They were very accommodating to our schedules and were able to provide dates and times that we needed. The entire process was smoother and just simply easier than any other contractor that we've worked with in the past. We highly recommend Window Nation!

The 2nd set of 5 replacement windows…
The 2nd set of 5 replacement windows also had warped frames which allowed bugs into my house. This was the same unacceptable condition as the first 5 windows. I compared my other 17 year old windows in my house and found no warpage at the bottom of the screens. I also went to a big box store and checked several of their windows, and did not find any warpage. The service manager tried to say the warpage was normal. I called 2 different manufacturers of windows, and they confirmed that there was a defect. I plan on finding another company to replace those 5 windows. I wish it ended better.

We appreciate your feedback and regret that this was your experience. It's concerning that our service manager suggested this was normal; we will be looking into your account further to determine what happened and how best to proceed.
