Window Replacement
Window Replacement in Commerce City, CO
Commerce City sits just northeast of Denver — a place where long-established neighborhoods and new developments grow side by side, with Dick’s Sporting Goods Park and the open prairie at its doorstep. Plenty of homes here are at the age where windows start failing: seals fogging up, frames warping in the sun, drafts sneaking in every fall.
Window replacement in Commerce City, CO takes care of all of that in one project. Better comfort, lower energy bills, and windows that open, close, and lock like they should.
Velazquez Windows is a local, owner-operated company serving Commerce City and the Denver Metro. We measure every opening ourselves, install with our own crew, and put every price in writing before we start. No salespeople, no pressure, no surprises.

Commerce City Homes Deserve Better Windows
Here’s how it works with us. You call or send a message, and we set up a free in-home visit — about 20 minutes. We walk through your home with you, check every window, and measure each opening by hand.
Then you get a written quote with a price per window. Every opening, line by line. No lump sums, no fine print, no discounts that only exist if you sign on the spot. And if a window is still in good shape, we’ll tell you to leave it alone.
Plenty of companies offer window replacement in Commerce City — what makes us different is simple: one owner overseeing the job, one crew doing the work, and a price that doesn’t move after you say yes.

What’s involved
The Detail That Makes it Last.
An Estimate Based on Your Home, Not an Average
We don’t quote over the phone or price off listing photos. We come to your home, look at every window in person, and measure each opening by hand. That’s how you get a price tied to your actual house — and windows that fit right the first time.
Vinyl or Fiberglass — What Your Money Buys
We’ll show you both and be straight about the tradeoffs: vinyl gets you efficient, low-maintenance windows at a fair price; fiberglass buys a stronger frame, slimmer sightlines, and a longer lifespan. We’ll tell you what we’d pick for our own homes, then the decision is yours.
Glass That Stands Up to the Colorado Sun
Commerce City gets serious sun, and old glass lets it pour in — fading furniture, heating up rooms. New Low-E double-pane glass cuts that heat and blocks the UV that bleaches your floors and drapes, while keeping winter drafts out too.
Your House Isn’t a Jobsite
We work room by room, cover your floors and furniture, and haul every old window away with us. Most Commerce City homes are finished in a day — two at most for bigger jobs. You come home to new windows, not a construction mess.
