When replacing windows or doors, there is only one chance at getting it right. And we take that very seriously at Dun-Rite.


You may have heard that replacement windows are all about the window itself, we agree… in part! That’s why we always start with top quality products with a Click to View Project Galleryproven track record. But, there is definitely more to replacement windows than just the window.

The other, often overlooked components to a first class window project are:
-The Installation Company
-The Installation Method

Dun-Rite Window Replacement Denver

We’ve been remodeling Colorado homes since 1985. People trust and know that Dun-Rite strives to eliminate the risk in a remodeling project by using our own employees for installation (not subcontractors), carry full liability & workman’s compensation insurance, and… put quite simply… we always treat our customer and their homes how we want to be treated.

When it comes to the installation of your windows, we are picky! We will always use the best possible installation techniques with the least disruption to the interior and exterior of your home.  Your project will also be handled “turn key”. Meaning, when we’re done… you’re done. All necessary trim, painting, caulking, and any necessary finishing touches are included in your guaranteed quote.
