Who We Are
Denver Window Center is the ProVia vinyl window storefront of Gravina's Window Center of Littleton®, a family-owned window and door company that has served Colorado homeowners since 1973. For more than 50 years, the same family has measured openings, installed windows, and answered the phone afterward, through every kind of weather Colorado can throw at a house.
Why This Site Exists
Not every home and budget calls for the same window. This site is dedicated to the vinyl side of what we do: ProVia Endure windows and patio doors, built to order in Ohio and backed by a lifetime transferable warranty. We chose ProVia for vinyl the same way we've chosen every product in five decades, by watching which brands hold up at year 15 in Colorado conditions and which ones generate service calls.
Where We Work
We install throughout the Denver metro area, including Littleton, Highlands Ranch, Englewood, Centennial, Lakewood, Aurora, Parker, Castle Rock, Boulder, and Broomfield, and we regularly serve mountain communities in Summit County and the Vail Valley. If you're not sure whether we reach you, call and ask; the answer is usually yes.
