We sincerely regret the extended delay in processing your refund. We understand your frustration and are actively looking into this matter to ensure a swift resolution for you.
Hard sale
Hard sale! Nothing is itemized, leaving you wonder how they came to the total cost. Discounts used, and taken away, if no same-day commitment. No time to consider a large purchase, such as ours. Windows/door are just okay! They do not offer a full replacement, with new framing. They will use what’s there. You will also be told the installers work for them, as employees of the company, and that’s stretching the truth.

Window Replacement
In 2022 you installed 8 windows form. 2 years later you replace one with a stress crack. A couple of weeks ago another window had a stress crack. I called and the window was ordered, but the wrong size was delivered so we have to wait another couple of weeks.

WN provides more than just windows
From our salesman Rob, to our scheduler, Stacey, to our installer Erick and his crew, we had a great experience. Everyone’s knowledge and expertise was incredible.
