The person who came out and did work was good and professional. My only complaint is it's a little spendy, but very happy with quality. I would recommend, but it's a little bit on the high side.

Very professional work and they kept us updated along the way

Their installers are amazing, but their office is really unorganized.

The salesman fell off after the original visit. He wouldn’t respond to any communication at all. We had questions which had to be answered through the regional manager. Second issue was false advertising on your vehicles. It was promoted on the vehicles siding and doors is also done through the company. We were told the advertising on the side of the vehicles is 100% false. Windows is the only things you do in St. Louis which makes no sense. We hired the company doors and siding could be done as well. Didn’t find out until after the windows were being manufactured windows is all you do. We felt as if a bait and switch happened. If we knew you only did windows then why use the company? Go and use a general contractor for work. I also have a feeling warranty claims won’t be easy. The customer service call center could use a lot of work. Called to have someone call me for serious questions to be answered and had to request many times for a person to call me back. The rep read what sounded like a script over and over again not listening to what I was asking or saying. The regional manager was awesome and was great of addressing issues.

From scheduling the estimate to the measuring appointment to installation, everyone was prompt, professional and did great work!!

I had an amazing experience with everyone until I had to reach out to management. I didn't have a good experience trying to work with management to get information on the second half of my windows completed. It's been a big issue and held up my refinancing.

On time, very professional, courtesy and did a Great job of installing and clean up.

You did everything you said you would do and the sales rep. offered different options than other companies that were better for us.

The quality of the windows is not good.

We are a return customer, the first experience was incredible. The second time around communication was non-existent and difficult. Dates changed, when they finally came to do the work things were missing and / or not done correctly (like a door not fitting so it didnt lock and my 3 year walked outside by herself) no apologies along the ride just frustration and dozens of phone calls to managers, etc. to just get the work done.

I have been trying to get friends that need windows to contact you but so far noone has.

I feel that Rob, the salesperson, is their biggest asset, and he's really good at his job.

Installers did a great job! They were cordial and cleaned up after install!

I am likely to recommend Window Nation to a friend. The guys who installed the window were very nice and professional.

Everyone was friendly, and did a great job

Quick service and great installation crew.

The installers seemed to throw the windows in and left broken glass, left over parts and pieces?

They haven't finished the job and left me with windows I can't open. The financing company through Window Nation had already paid them, and I thought it would be when it was completed. They didn't bring out a screen and left me with windows that are not working properly.

I am very pleased with their work.

I like the windows and the installers. They set up the schedule three times. The windows were delayed.

Window nation has great prices, and the installed products are very nice but I had one miss measured window, and for damaged windows. And they were about to be installed that way until me as the homeowner found them and alerted the install team. The install team left a dirty and dangerous job site with nails on my living room, floor and glass and screws on my driveway. The install team damaged some of my property during the install and didn’t mention it. The communications process with the local branch to resolve this has been substandard. I had to reach out to them first after the install, and I haven’t heard from them since, not even regarding the replacement date of the windows. however, like I said, the pricing is great, so I will leave it up to y’all to decide what you’re willing to tolerate.

Install crew for my windows did not clean up before leaving. I found several screws on my driveway and several pieces of sharp metal laying around my house

Have not heard from anyone

Brian,

I wish I could have given a 5 in every category, but I don't feel that would be accurate. I wish that someone would have listened to me that I was very concerned about the measurement of the windows. When the man came to do the final measurement he admitted he was hung over from celebrating his birthday the weekend before. I took personal measurements and they were different. I then called into Window nation to get the final measurements. I told them that I was concerned about the measurements. NO RESPONSE. When the installation crew arrived I told them I had a concern. Only one man spoke English and I don't believe he understood what I was saying. I am going to attempt to add a picture of the gap in the windows. You tell me if that would be acceptable in YOUR house? I had twelve windows installed and they all had gaps. They attempted to fill those gaps with the expandable material which I do not find acceptable for that size gap. The windows can not be opened with just one finger as shown by the original salesman.

The next issue would be that the crew did not reinstall the shades and shutters as they said they would. When my wife questioned this they reinstalled the shutters and tore up the wood work. This causes another problem. I will attempt to add a picture. I reinstalled the shades myself. They tore up the shutter wood terribly.

One last issue. The installation crew were all Mexican. They all spoke Spanish. They assumed that neither my wife or I understood Spanish. I put on music that they thanked me for. I had it playing on both levels of my house for them. My daughter and her friends came over to my house with young children to swim. What the men were saying in Spanish was not acceptable. When they went to reinstall the shutter the man said in Spanish how cheaply built our house was. My wife replied in Spanish how expensive everything was especially the shutters. They finally stopped talking!

When someone calls you a “punta” in Spanish, they are using it as a derogatory term to insult or demean you. The term is often used to refer to someone as a “prostitute” or a “whore.” It is important to understand that this term is highly offensive and should not be used in any situation.

I would not recommend Window Nation to anyone.

Sincerely,

Thomas Teschner
