Horrible Experience Never Use Window Nation Again
Window Nation said they could make windows and then could not, they said they would install before winter started and did not they installed in the middle of the winter after months of delays. Window Nation had to make the same windows three times, had to remake slider doors twice, I had leaks into my dining room and bedroom which damaged Sheetrock and hardwood floor buckled. Had rip out and replace with my own money. I had to threaten Window Nation with a law suit for them to complete repairs after almost two years of fighting them to complete the required repairs. I warn people do not use Window Nation I would not wish this on my worst enemies. Go with another company. You have been warned.

This company makes things right.
From the start, the combination of product quality and reasonable pricing caught my attention. What truly sets this company apart, though, is their exceptional customer service and professionalism — the main reasons for my high rating.
While we experienced a few minor hiccups along the way, Joe and Brandon went above and beyond to make things right and ensure we were completely satisfied. The installation team from Velasquez Windows was equally impressive — some of the most hardworking and courteous professionals I’ve ever met.
We were initially hesitant about making such a large investment, but I can confidently say this company stands firmly behind both their products and their promises. I highly recommend them.

Great quality and price!
I just got all 30 windows replaced in my house. The whole process was smooth, from my meeting with the sales consultant to the installation. I'm very happy with the quality, look, production wait time (only six weeks) and price of the windows.

Only thing I would have liked is the windows cleaned after installation. I won’t be able to reach into the window well to clean the exterior.

Warranty honored
On time, called ahead, analyzed the 'problem', and performed a fix on 'recently' installed windows and screens. The screens were bouncing/ rattling in high wind, hopefully his improvised solution will work, without further issues.

We appreciate you taking the time to share your experience. We're glad the technician was punctual and thorough while addressing the window screens. We hope the adjustments made resolve the issue with the rattling.
Not a Great Experience
After receiving an incorrect order the first time (I ordered flat grids, not contour), the company came out again to put in the correct grids. There were both manufacturing and installation problems, so the installation manager ordered three new windows with flat grids. Yesterday, the company came out for the third time, and brought panes with contour grids – not three new windows as promised. I have not heard back from anyone regarding the status of the three new windows. It has been an extremely frustrating situation. Also, I was supposed to have received a check for the difference between flat grids and contour grids; however, the check has never arrived.
23 octobre 2025
Réponse de Window Nation - Denver
We regret to hear about the multiple issues with your order and installation. We apologize for the incorrect grids, the repeated visits, and the missing check. We are looking into the status of your new windows and the refund. Thank you for bringing this to our attention.
Too Notch
From sales to the insall communication was great. Everyone was timely, professional and spot on with their communication for expectations. Install team worked hard and cleaned up after all they did. In 3 months time I've had to have 5 major repsirs done. Working with a number of different contractors Window Nation's team is #1 for meeting expectations. Not to mention I love my windows. Additionally, with the warranty team, due to feedback from another contractor, Window Nation's customer care and warranty team hit too notch once again. They continue to work for you and make you feel like a valued customer. I love my windows!
