Gravina's Windows and Siding is a family-owned-and-operated Colorado company that has been serving homeowners for over 35 years.

Our Story Began...

…in 1972 Larry Gravina started working for his father in the home improvement business. He worked for 16 years learning the in’s and outs of the window, siding, and construction industry before he decided to go into business for himself.  Building the name of Gravina’s as a  legacy and reputation of integrity in the Denver Metro area in 1988. Selling windows door-to-door, he laid the foundation for a company that would go on to be one of the most successful windows, doors, and siding companies throughout Colorado.

Since then, Larry’s son Nick Gravina has worked his way up to a leadership role and currently manages day-to-day operations. Nick started working for his father in 1997. Larry has 50+ years in the industry and Nick has 25 years in the industry.

From day one, we've brought work ethic, honesty, and integrity to every job, small or large!

Colorado-Bred, Colorado-Focused

Our success as a company owes a lot to this wonderful state. We’re proud of our Colorado heritage, and we keep our focus on helping homeowners in the Metro Denver and Fort Collins areas.

We’re not a big-box store. We’re not a national chain (and we don’t want to be!). We’re just passionate windows, doors, and siding experts with decades of experience and a genuine desire to help you.
