Excellent service before, during, and after install
I have replaced nearly all of my windows and several doors with Window Nation. They always make sure I am satisfied with the work. I will be buying my remaining windows with them and recommend them highly.

Poor service experience
Holly and Mike our Sales guy were the only positives in our experience. The manager could not make time to follow up with me on a request and installation was submitted par to say the least. I will not be recommending their service.

Good quality windows
Good quality windows. The installers took their time to ensure a thorough job was completed in installation and to not cut corners. There was a slight delay in arrival of windows from manufacturer, but I recommend this company and their attention to detail. Thank you.

Very happy with our new window
We had an old garden window replaced with a slider window. It was time to have it replaced after living in our house for 31 years. It was getting bad. In winter ice would form on the inside on extremely cold days causing moisture that in time created mold. Hence making it hard to keep clean. We are really happy we chose Windows Nation. The service we received was high quality, from the initial visit for the pricing to the measurements and finally the installation. Everyone we dealt with at Windows Nation was friendly, helpful, accommodating, and very professional. We will definitely use them again in the future when necessary.

Communicate
Communicate. I only got the one phone call changing the installation date and that was it. I didn't know if it was am/pm nor did they confirm the day before. I also didn't get any pw from the salesperson only your folder. Nothing on finance.

The install left some cracks in my front window siding not filled with caulk. Pine trim was ours and it was reused as was parts of previous inside window framing in our basement window replacement that was not discussed. No walk through or explanation of process provided per salesman’s sales pitch. I picked up nails from grass no magnet sweep completed at end. As we had a language barrier perhaps Installers may not have understood my questions.

Difficult to schedule but product looks good
They were timely and fast. Windows look great.
Stickers were left on windows which left us homeowners with work to do. We were told they would repair screens from previous installation which was not done. Not a lot of flexibility with scheduling
