We are a division of LR Contracting Inc. specializing in window replacement. Our staff has 20+ years of combined experience in window and door installation and replacement. LR Contracting Inc. has been serving the Denver area since 1994, with thousands of satisfied customers and a Gold Star rating with the Better Business Bureau. We are responsive to our clients, provide professional service, and perform high quality workmanship. Let us help you!

We install high quality windows and doors from manufacturers like Milgard, Simonton, and Anderson to name a few. All our replacements meet or exceed Energy Star Ratings and our installations focus on preserving the integrity of the perimeter seals, setting a window or door properly to insure operation and usage over the life replacement, and maintaining the appearance both inside and out that your home deserves.

Almost all of our window and door replacements include the complete removal of the existing unit and installation of the new. This is done to address the preparation of the opening before installation, proper installation of the new window or door, and rebuilding the weatherproofing seals after installation. This is the process recommended by all manufacturers, building departments, and the AAMA (American Architectural Manufacturers Association). Not all window and door replacement companies put this kind of time and effort into their replacements. At LR Contracting Inc. it’s what we specialize in.

But it doesn’t stop there. Since we are a full service general contractor we also specialize in the refinishing of the interior and exterior of the house due to the installation. We handle the painting, drywall and texture repairs if needed, and can even modify existing openings to allow larger window or door sizes, or replacing windows with doors.
