I never enjoyed spend so much money at one time. Our sales associate was amazing and very knowledgeable. We didn’t feel like we were being sold a product, we felt like we were making an investment purchase.

Was not given accurate information around labor warranty. Was told lifetime but it's only 5 years after install. Got told "it recently changed" but feels like a bait and switch. Also picture window has been broken twice during install and repair attempt left black marks on my wall

I’m still not sure of the quality of the installation so I don’t have a complete picture of the product or service.

Wonderful service, good quality windows, reasonable price

I don't know many people

We are so happy with our windows and the service!

Professional , friendly workers, swift installation, and fantastic cleanup. If the two men that installed are windows are any indication of your workforce I would not hesitate to use Chicago Nation again or would not hesitate to tell family and friends how I feel about your company.

Customer service is on point

I am completely satisfied with my “ bay windo w”” A bucket list !! dream list!!

I have recommended Window Nation to two friends.

Very quick, quality project from beginning to end.

Reach out to you guys it’s a problem did not happen. Also, my neighbor got Windows also She reached out to you guys. The guy left a message cursing on the phone.

Very professional 👏 and experience. If you had a question take the time to answer.

Windows wrong size and non-responsive about a resolution after acknowledging the problem. I will have to replace custom blinds and can’t so that until windows are replaced so I’ve had temporary paper blinds on my front window for 2 months.

The measuring employee was very knowledgeable and helpful

This was the second time for us in both times we were very pleasantly surprised by the craftsmanship and the quality of the workmanship

We just noticed a couple of cracks in our bedroom walls.

I wish i could give them less them a 0

I’m very happy with my new windows and would highly recommend Window Nation to a friend looking to replace the windows on their home.

Mis-measured out largest window and had to tape in the old one. For over month, I received no follow up. Contractors left mud stains on walls and carpet.

I was not given accurate information on the finishing of my bay window. Did not receive a follow up on my feedback from the sales person or through the online process

A few windows do not properly lock and I already have one window with moisture inside. It hasn’t even been a month.

The whole experience was flawless and they look great

I liked the product quality of the product & all their people--sales rep, measurer, & installer--were courteous, respectful, efficient, & good communicators.

Good price, quick work

Products are great we received our windows and new front door which we love. But the customer service after they got paid declined and the service wait times are horrible. Been waiting on a new lock for 3 months, still waiting.

Still waiting for my screens. I want them immediately!!

Reliable, with great installation service. Very responsive to any questions or concerns that you may have.

Called several times over 2 week period to get a tech to look at my window I was unable to lock. No follow up.

I am very satisfied, and the company did a very good job. They also gave us very good advice on what to do and what not, and they explained if we needed to make changes with the shape of the windows in terms of how it opens for easy cleaning.

I am in the building business. I have been for 60 years. The gentlemen that were here to do the installation, were the most professional carpenters that I have ever seen. I wish I could hire them. They were outstanding. They were a couple of men from outside this country, Europe somewhere that I assume. The precision you just can't believe. Cleanliness? I just was amazed and didn't think that existed anymore. But it does. That is what sold me on that company. It certainly wasn't the price. The windows looked fairly good, but we will know in about 5 years.

I am likely to recommend them to a friend because I love my windows.

The installation process was pretty quick. It took them five hours to do all the windows that were replaced, and they explained how the windows worked and things like that.

I am pleased with Window Nation and the windows; it was excellent!

The price, working with us on a payment plan. The quality of the windows.

They provided a nice, friendly service.

Window Nation responded to my questions in a timely manner. The installers were pleasant, knowledgeable, and efficient. My new windows were installed in less time than I expected.

After signing the contract for window installation that is being financed by Service Financial. I've been getting non stop spam calls daily.

The guys were very nice. Bought them lunch on the first day. The only problem I had was that they didn’t cover things with plastic like I was told they would do. After I said something the only thing that was covered was my grandson’s toys on the porch. Dust was everywhere. I had to clean all the bedding and everything else.

fast install

No customer service. They do not return phone calls.

Installers were very quick and efficient and did a great job.

A booklet should be included with your purchase explaining how to operate some of the windows

The installers were very professional.
Neat and quality workmanship.

The quoting and installation process were streamlined. The production and delivery process was a bit disappointing due to delays.

Professional, respectful, friendly

Pleased with the process salesman measurer and installers all caring and professional

Window Nation really came at the right time. We haven't been in the house for that long. They did a really good job!

I thought Window Nation was a good company, but I was wrong. Window Nation installed 11 windows for me, two of which had broken screens, and it took them two weeks to repair them. On October 27, 2025, they installed a door, and everything was fine until they installed the screen door. The handle was either broken when they installed it or they broke it during installation. A report was filed to have it fixed. They sent me an email saying the part had been ordered. Since they didn't contact me, I called, and they said they would inform the service department. Still, no one contacted me or called me back. I called Window Nation again. They said the same thing, that they would inform the service department. Today is December 8, 2025, and I still haven't received any information. The screen door is still without a handle, and I can't enter my house through the front door; I have to go all the way around to the back. I don't know when they will be able to install the handle. I definitely will not recommend Window Nation to anyone I know.

Excellent installation crew!
