They went the extra mile

“We had some weird shaped windows - trapezoid and just old in general. They came did a great demonstration and explanation on window. They were straight forward. The timing they said, was what was met. When there was an issue (because we had super old windows) they addressed it right away and let us know it would take extra time. They went the extra mile to make sure we were satisfied with service. Overall, fantastic customer service and top quality. It was fairly priced too, we had about 5 different quotes from around the area. #customerserviceonpoint #windowsanddoors #beautifuljob”

I simply can’t say enough!

“I simply can’t say enough about Prestige Window and Siding. Despite the many setbacks with the weather, their team worked diligently to get the siding done. Mark is a true artisan and did a wonderful job, making sure to address every issue with my husband and me. I am thrilled with the results. It’s like a brand new home. I would HIGHLY recommend Prestige Windows and Siding to anyone who wants the job done with honesty and integrity. They are hands down, the best!! Thank you Don and Mark.”

overall was a great value

“I had Prestige replace 7 windows in my 113 year old bungalow in Northwest Denver, and I'm glad I went with them. The price wasn't the lowest quote I got, but it was still significantly cheaper than some of the big names in the window business, and overall was a great value. Dustin is a great, no-pressure sales guy, James is a fantastic installer (even providing some alternative trim options to maintain the historic look of my house), and Bobby is a great field support guy. There were some minor issues with one of the windows, and they did a great job resolving it. I will absolutely use them again in the future.”
