I'd highly recommend this place! We made the decision to stucco our home and the company we hired had a cancelation so they started on our house immediately and we needed a few new windows. I called nearly 30 companies between Kansas and Colorado who all stated special order and 7-12 weeks out! I was in a panic! I finally found this company and they had windows in stocks. Some we had to downsize but not by much. Shaun was a great help through all the hardworking she put in for us and we couldn't be more thankful! Thank you!

I highly recommend this place. The prices were unbeatable and the customer service was top notch. I worked with Shawn and she was incredible. I had to do everything over the phone and she was so patient, helpful and spot on with measurements and finding what I needed. She even offered a window in the discount bin that I had no idea about, which saved me hundreds of dollars. Thank you for being so helpful, honest, and making this such an easy process!

This place is great! I've been doing some DIY window replacement on my house. They have every size in stock. Garrett is the guy to talk to.

Garrett is awesome, he taught my much about what kind of windows and doors would be needed in constructing my new little cabin!

My absolute "go to" person at this store is Shawn. Her knowledge and follow-up is amazing. This is the only door and window vendor I use, or recommend, to my real estate clients.

Very nice people. Great customer service. Bought a brand new overstock Renewal by Anderson window at a killer price and they fabricated custom trim.

Do not know much about them only been there once. But the employees are pretty friendly. The only thing is if you need to make a return they have a huge restocking fee percentage.

Not so much of a discount store as described, however, they do have quite a bit of windows, etc in stock. They will even install them for you. It's hard to find and even trickier to park. There are signs on the fence that direct you to the back, so look out for them. The guys who assisted us was not too enthusiastic, but helpful. He showed us a line of windows on display that ranged from inexpensive standard builders grade to top of the line grade. Come to find out they didn't have what we needed and kind of glad as well as we found similar windows elsewhere for a fraction of their "discounted" cost.
