Window Styles

Replacement Window Options to Suit Your Home Perfectly

Awning windows are hinged at the top, allowing them to open outward from the bottom to provide premier ventilation along with protection from the rain. Casement windows are similar, featuring a crank-style handle that opens these windows outward from the side.


Bay, bow, and garden windows are uniquely beautiful in that they extend outward from the home, thus adding visual dimension and functional space wherever they’re installed. No matter which of these styles you choose, you can count on us to install them flawlessly.


Designed to slide open with the kind of ease you'd find with a sliding glass door, horizontal slider windows are a great choice for virtually any room within your home. And since ours come from renowned manufacturers like Anlin and Vanguard, they'll look and perform like-new for many years to come.


Built with one fixed sash at the top and one operable sash below, single hung windows can be slid open from the bottom whenever you want to let in a breeze. Double hung windows provide slightly more functional versatility since they can be opened from both the top and bottom, all while offering the same classic aesthetic appeal.


Have something more unique in mind for your home window replacement? Geometric windows are the perfect option for you, as they offer immense visual interest as well as thermal performance. Choose from a wide array of shapes to find the right fit for your home.


Mulled Units are multiple window sets that are joined together with a vertical or horizontal mull joint (or both). You can mull casements, double- or single-hungs, sliders, and geometric shapes into multiple window unit sets.

Hear From Our Customers

We’re proud of the work that we do, and our customer reviews speak to the kind of quality you can expect when you partner with us.

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.”

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”
