Best Replacement Windows and Doors Company in Denver, CO

We aren’t just a top windows and doors company in Denver—we offer a lot more than that. In addition to our exemplary track record installing custom replacement windows and doors in the Denver area, we have spent the last 18 years diversifying our offerings to include the sale, inspection, repair, and replacement of: 

  • Roofing  
  • Blinds 
  • Paint 
  • Decks and patios

We also offer hail damage inspection and repairs. Like our window installation and replacement offerings, our additional services are covered by the same Tru-Choice, Tru-Price, and Tru-Fit guarantee and come complete with our lifetime Tru-Warranty coverage.  


Roof repairs and roof replacements are among the costliest and most time-consuming projects homeowners face—but they are also among the most important. At Colorado Window Source, we utilize our in-house guarantees to ensure fair prices, attractive options, and the best fit for your home.   

In cases of hail or wind damage, it can be difficult to determine the extent of damage from the ground or without the expertise of a professional. That’s why we provide free estimates!  If your roof is damaged, our technicians will thoughtfully guide you to the best choice in shingles, gutters, asphalt, and more—depending on your roof’s unique needs.  

Window Blinds  

We provide window blind installation for sliding doors and windows of all shapes and sizes. Utilizing Hunter Douglas’ signature Versatile Silhouette window shadings, our product experts will recommend the best product for stylish and effective privacy solutions.  

Like all our products and services, our blinds are covered by our Tru-Choice, Tru-Price, and Tru-Fit systems so that the end result is always your satisfaction. Thanks to Hunter Douglas’ robust range of offerings, our team is able to provide aesthetically pleasing and functional blinds that will last for years to come.   

The Alustra Collection of Silhouette shadings includes color-coordinated headrails and a variety of soft hues to match your desired look in residential and commercial spaces.  


At Colorado Window Source, we recognize that one home improvement project often begets another. If you have opted for window, door, blind, or roofing replacement, you may also be interested in our home painting services.  

Thanks to our in-house Tru-Finish guarantee, we provide both interior and exterior professional painting services. Whether you need touch-ups, a renewal for your home’s existing paint colors, or you are in the market for an entirely new look, Colorado Window Source can do it all.  

In addition to our painting services, we also offer new window sill installation, interior jamb and casing, exterior brickmould replacement, or installation in worry-free vinyl or wood as well as attic insulation, window cleaning, solar-powered attic fan installation, skylight installation, and professional carpet cleaning. 

Decks and Patios  

We aim to be your one-stop-shop to the home of our dreams. That’s why we’ve expanded our services to include deck and patio construction.
