Excellent product totally professional installers
Excellent product. Installers could not have been more professional and efficient. Twelve windows and one entry door replaced in one day. Installers left the house as clean as they found it.
Absolutely beautiful windows and door. I could not have been happier.

From start to finish I have had such a smooth and easy experience. The install team did a great job and were very thorough. We only did the windows that needed immediate attention for now but will be using window nation for the rest of them when the time comes! Highly recommend

The job was started onJune2,2025 and…
The job was started onJune2,2025 and the windows are as promised, except one of the screens was missing. I got an email on June 6 saying the screen would be in stock by July 12. Then on June 23 I got another email saying the screen would be in by July 16. Finally, I got a call around that time to schedule the installation of the screen on July 29. It was done today.
Now I have to have the building inspection completed on August first. I am happy this is almost done, but I want my contract date to start on August 1,2025, not June 22, 2025 as my account statement reads.
My last screen was installed and the job is now almost complete. The local building inspector failed the inspection back on June 30, 2025. He claimed no one was home, but I saw his car in the driveway and went to the door but he was already gone!
Neither the town nor W-N ever contacted me to tell me of the failure and I only found out yesterday after calling the Stratford building dept. I re-scheduled the inspection for Aug. 1, at 7-8am. I also attempted to call the Service Finance Company but the phone number I have is only automated to make payments. Next, I called W-N customer service and spoke to someone about changing the start date, and ending date, on the no interest loan as the job is still not complete. I was told I would receive a phone call, but so far I have not. I have tried to find a general phone number for the loan company on the internet but without success.

I recently had some windows installed in May, and initially they weren't the correct sashes that I paid for. No biggie, they installed the frames and would replace the sashes at a later date.
Two months later when the replacement sashes arrived there was no proper labelling on the sashes that confirmed that they were the appropriate ones. It appears that the actual labels were torn off which left me very suspicious and not confident at all.
While overall my new installations came out looking nice, I really wish that Window Nation got my order right the first time. If they had-- my review would have been higher-- but since I still am trying to get the right sashes installed this review gets taken down a notch.
Oh and they also messed up my order of screens...twice.
Great looking windows, botched order.

One window cracked in two places
One window cracked in two places. Another has a gouge in it with white vinyl showing. Installer tried to color it but not good. Waiting on resolution. Took a few attempts to get someone to acknowledge defects. Also no follow up as to installation. They just showed up despite being told would get call day before for time window and installer would call when on way. Nope
