Window Replacement
Window Replacement in Littleton, CO
Littleton is a city of character — historic homes near downtown, mid-century ranch houses, and new builds going up across the south metro. But old windows don’t care about charm: drafts, fogged glass, and stuck sashes show up everywhere. If that’s your situation, window replacement in Littleton, CO is one of the smartest upgrades you can make. Velazquez Windows is an owner-operated company serving Littleton and the Denver Metro. Every window is measured, fitted, and finished with care — whether it’s one problem window or the whole house.

Windows for Every Littleton Home — Historic to New Build
Littleton’s housing stock is wonderfully mixed, and each era brings its own window problems. Original wood windows in older homes rot and stick. 70s and 80s aluminum frames conduct heat straight through. Even newer builder-grade windows lose their seals. Our Littleton replacement windows solve all of it — modern, energy-efficient units fitted to your home’s actual openings.
What we install:
- Double-hung, casement, slider, and picture windows
- Bay and bow windows
- Vinyl windows — the practical, low-maintenance favorite
- Fiberglass windows — stronger frames with slimmer profiles

- Energy-efficient windows with double-pane, Low-E glass
- Insert or full-frame window installation, matched to each opening
From historic remodels to new construction replacements, windows in Littleton homes get the same careful treatment from our small, owner-led crew.
What’s involved
The Detail That Makes it Last.
No Two Openings Treated the Same
Especially in Littleton’s older homes, no two window openings are exactly alike. We measure each one individually and order windows built for those exact dimensions — no shimming a stock size into place and hoping for the best.
Matched to Your Home’s Era and Style
A 1920s bungalow and a 2000s two-story shouldn’t get the same window recommendation. We help you choose replacement windows in Littleton that respect your home’s architecture while delivering modern comfort and efficiency.
Low-E Glass That Earns Its Keep
Colorado sun is brutal on south and west-facing windows. Insulated double-pane glass with Low-E coatings cuts heat gain, reduces fading of floors and furniture, and keeps winter warmth inside — real, measurable comfort.
Respectful of Your Home, Done on Schedule
We protect floors and furnishings, remove old windows cleanly, seal and finish every opening, and leave the job site tidy. Most window replacement projects in Littleton are completed in one to two days, on the schedule we promised.
