Home Window Replacement

When you need new residential replacement windows, you don’t want the hassle of dealing with one company to sell you the windows and another to install them. We cut out the middleman by selling and installing vinyl-framed replacement windows from Vanguard, Anlin, and Simonton ourselves. Our team has a combined 100 years of experience in installing residential replacement windows. We’d love to put that experience to work for you.

The Installation Process

We will pay great attention to the details when we’re installing your replacement windows. Replacing windows is as much about removing the old windows properly as it is installing the new windows. First, we cover your furniture, floors, and other valuables in your home with tarps and drop cloths wherever needed. Then, we will painstakingly remove the old windows and frames, aiming for as little glass breakage as possible. After that, we clean and prepare the window opening for the new windows to be installed. Then the fun starts—we get to put your new windows in place!

We start with your new window frames. The main frame of the window is placed into the opening and squared up. When we’re satisfied with the way it’s sitting, we screw it into place. The frames are measured several times to confirm squareness and leveled to assure plumb. Then we add the sashes and the vinyl interior trim, seal the trim to the frame, and the inside is done.

When we finish the inside of your replacement window installation, we tackle the outside. First, we stuff insulation between the window frame and your walls for maximum energy efficiency. Then the exterior vinyl frame is set in place to weatherproof your windows.

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 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.”
