Poor replacent window notification
One of the windows did not have a grid. Told the replacement would be in on the 25th. Called their Customer Service "?" (out of country) on the 27th (Monday) for status. They told me someone will call me "Sometime this week" to set up an appointment. After not receiving a call by Wednesday called the local store. They told me the window was actually in on the 18th. Transferred me to installation. Was told they can come out sometime next Thursday and will let me know sometime on Wednesday when. Told them I am not wasting two days. Was then told they will be out between 3-5 pm on Thursday. For any problems contact local store. Their out-of-country Customer Service is useless.

the installers were prompt, courteous and respectful. The product looks nice, I hope it is as good as it looks. The Pella windows looked good when installed, they proved they were not as good as the description given to us.

Great Windows/Poor communication
I like the windows and happy with the purchase. Biggest issue was lack of communication between the time of the 2nd measure until they showed for install. I did have an email that said my windows would ship on Dec 2nd, but the installers showed up on Dec 1st without warning. I had to scramble to get the windows prepped taking down the curtains and blinds in a frantic mess. Now I have to replace some of the blinds because I was in too much of a hurry as I had to do the work by myself that I would have normally had a 2nd person help me with. Every other type of company I’ve worked with sends texts or calls the day before as well as the day of. All I got was a k o k on the door.

Customer service is terrible no return…
Products, installation, and Customer service is terrible. No return calls when requested. Wrong windows were installed and had to replace with correct windows. We were to receive a 100.00-dollar gift card for our sales call which we have never received. Installation crew was to have one worker that spoke English on the job and they spoke broken English. Was difficult communicating with the crew. Very disappointing experience and feel like we were way over charged for the product service and installation I would not recommend WINDOW NATION. Are last service call being 11/18/25 initial installation was in June.
Sadly, still not satisfied with the WIDOWS,

New window installation from Window Nation.
The installation team showed up on time and completed the job in about 4.5 hours. The put tarps down to minimize tracking in dirt. Overfall they were very professional.
The windows look great, the temperature distribution on the ground floor is much more even with the new windows and the furnace is working at longer intervals so farf.
