I found that Window Nation oversells their product. The installation has been less than satisfactory while their response to my project has been going on for months. The project is still incomplete to date, the windows are fine but I am hesitant to recommend anyone to Window Nation. I do not believe that their installation is up to my standards.

Great product and service. We did have a.few issues with installation schedules. They ended up having to reschedule us two different times.

They were very courteous and professional installers. I'm very happy with the work they did.

I was very satisfied with the service. They explained how the windows worked. The roofers were courteous, on time, and very accommodating with what I wanted done with the windows. I wanted to put some casing around them. I was pleased with the entire operation.

Everyone involved in the process was courteous, professional and helpful. The windows were installed quickly. All areas around the installation were cleaned up. There is no more cold air coming in from the windows. They look terrific, inside and out. I would gladly recommend this company.

Once the installation team had the windows, the installation of 19 windows took a day. The installation crew was courteous and friendly. They did a great job.

The whole process seemed to be pretty seamless and effective. The installation seemed to be on a time schedule as they were rushing the project. On 2 window frames, not the windows themselves, the framing the guy said his "tool got away from him" and took out excess drywall and damaged the metal window jam. He did patch it, but it wasn't a great patch job. I had to spend more money to patch it myself and spend $50 in paint to paint the entire wall. You can't just paint a 6" by 12" section.

Window Nation did a great job. I have never had anything done like this before at my home. Everyone that I worked with in this company was more than courteous and helpful. I have no complaints with the customer service at all, they have been great to work with.

We love the windows. They are awesome and look fabulous!

Everything went pretty much according to plan with the exception of one kitchen window. We had two windows replaced with sliders behind the kitchen sink in the corner of the kitchen. One opens left to right like it should for easy access. The other adjoining window also opens from left to right which makes it impossible for my wife to reach it, since she has to reach all the way over the sink and back in the corner to get to the handle. It should open from right to left. They said they could replace the slider for two hundred and some dollars. I just spent almost $17,000 having every window in my house replaced except for the transom window over the front door, and they can't fix their design error and eat the 200 bucks. So much for their "complete customer satisfaction". Everything else was great, but they sure left a bad taste in my mouth.

They did a good job, and it was an easy process from beginning to end. It was amazingly easy to get my whole house done.

I love my new windows and was very pleased with the installation and crew but I was saddened that my blinds did not fit back into the windows. At no point in the process did anyone ever mention that they may not fit after installation. I had to scramble to cover my windows with anything I could find including sheets and shower curtains to ensure my homes privacy as I live on a corner lot while I shopped for new window treatments for a total of 12 windows. Quality window treatments are not cheap. It was a very unexpected expense which I would have rather been more prepared for.

I am very happy, we were apprehensive about spending that amount of money. However, we are happy we did, because it looks great.

I would tell people that they should choose a different window company, and be smarter than me and check the Better Business Bureau.

Window Nation installed our beautiful windows a little over a week ago. I love them so much that I have not even rehung our blinds because I don't want to cover them up. Installers were awesome, had to troubleshoot some of the old windows original to our old home. All around great experience!

There was not a crew of qualified technicians installing the windows. Only one person knew what to do and worked 13 hours straight.

Go with a different window company.

The Window Nation - St. Louis installers were extremely professional!

Installation was excellent but the scheduling and communication from the company is horrible.

I was glady received as a first time customer. From the beginning to the end, Joe would take care of everything until he knew me by my first name. I don't have any negative to say. Everything went as smoothly as the way Joe talked to me. I am satisfied! People have been standing outside staring at my new windows! I have so much light coming in my house now. I almost don't want to put curtains up because the windows look too good. I'm just happy about everything. My house is in good order now!

It was everything we expected. They didn't let us down!

The installation and the windows look better than when the house was brand new!

The guy who installed my windows was fabulous! He was an absolute perfectionist and was great!

The installation was done well.

They were all very professional. The installer was a neat freak, in the best way. He kept the site clean and I was very impressed.
