Original install of picture window has…
Original install of picture window has a molding piece incorrectly cut and installed. Installer put putty in the corner of one of the molding pieces to hide the imperfection but the putty popped off. It’s taken almost a year to get this fixed! They have come out twice and each time have brought the incorrect style of molding. And most recently last month. Maybe 4th time will be the charm?!!! The installer that most recently came last month admitted that Window Nation has not focused on Quality or customer service due to cost constraints. Not a great look for Window Nation. They are one of the cheaper window companies out there, but be careful, you get what you pay for!

The technicians that installed my replacement window did a fantastic job but I must say the reason I gave four stars instead of five is because if window Nation would have the sash then this job would have been very easy to do in this case. These guys worked very hard to get that window installed being that it was just the glass. But again they did a wonderful job.

Very frustrating
Placed a warranty claim on one of our windows that the glass had cracked. Of course I had to pay $150 up front for labor. Then I had to keep calling as I received no response from WN. So then the tech shows up at our house but without the replacement glass. To make matters worse, once the tech got the replacement glass, it cracked as well. So now I will have to wait another 6+ weeks. Horrible customer service!!!

The installers were prompt and efficient, left the site clean, and made the service repairs to damaged screens from manufacturer defect and shipping damage at the time of install. The windows made immediate noticeable improvements to the house's heat envelope.
