Custom service lacking
I did not receive a call the morning of installation before arrival when i swore i was told i would. I did not like the fact that the workers were not fluent in English - which made it difficult when I was unsure about the amount of caulking on my marble windowsills. Also, no one from Window Nation contacted me after until i contacted them. I would have thought my sales rep or higher up would have reached out to make sure all went well.

Great product and great service
I had six windows replaced on 10/10/25, including one wide, 3-part picture window. From first contact to installation, from sales rep to installer, my experience was positive - rep was on time (early, actually), professional, friendly, thorough and knowledgeable in his explanation and demonstration, patient with my questions, and easy to contact afterwards. WN kept me updated on estimated installation date and were flexible to accommodate my schedule. The installer was also on time and kept me informed of his arrival time. He, likewise, was professional, friendly, got the job done quickly and well, and cleaned up spotlessly. I'm very happy with the products, the employees, and the company and would highly recommend them.

The guys that came to install were great. Answered questions, very polite and cleaned up everything and made sure we were happy before they left.
I didn't realize the glass would be a bit smaller with the casing around it, but the previous windows has no casings.. but no big deal. The IV protection will be great in the summer keeping the heat of the sun out. Thanks to everyone at Window Nation.
