Window Replacement in Lake Mary, FL

Colonial Window & Door is based right here in Lake Mary. We've been replacing windows and doors for Lake Mary homeowners since 1996 — free in-home estimates, no salespeople, and installations handled by the same trusted crew Tom has worked with for years.

Your Local Window & Door Company — Right Here in Lake Mary

A lot of Lake Mary homes were built in the 1980s and 1990s, and many still have their original single-pane windows or early-era builder-grade units. Those windows weren't built for Florida's summers — and 30+ years in this climate shows. Fogging between the panes, drafts, higher cooling bills, and frames that have seen better days are all signs it's time to upgrade.

Colonial Window & Door has been taking care of this exact problem for Lake Mary homeowners for nearly three decades. We're a family-owned, owner-operated company — Tom measures every job himself, factory-orders your windows custom to your home's exact specs, and Tom's long-time installation crew does the work — the same trusted team he's relied on for years. No high-pressure sales tactics. Just straightforward work done right.

Why Lake Mary Homeowners Replace Their Windows

☀️

Florida Heat Is Hard on Old Windows

Older single-pane windows offer almost no thermal resistance. In a Lake Mary summer, that means your AC is fighting the sun all day. Low-E glass with Argon fill makes a real difference in how much heat enters your home.

💧

Humidity Breaks Down Seals & Frames

Fogging between the glass panes is a sign the insulating seal has failed. Humidity also warps wood frames over time. Modern vinyl frames hold their shape and won't rot, warp, or require repainting.

🌀

Storm Season Matters

Central Florida gets its share of wind and heavy rain. Properly installed, properly sealed windows reduce water infiltration during storms — and give you more confidence when a strong system comes through.

💡

Lower Energy Bills

Energy Star-rated replacement windows reduce the thermal load on your HVAC system. In Florida's long cooling season, that can add up noticeably over the course of a year.

🏠

Curb Appeal & Home Value

New windows refresh the look of your home inside and out. Whether you're planning to sell or stay, updated windows are one of the more visible improvements buyers and appraisers notice in a Lake Mary neighborhood.

🔇

Noise Reduction

Modern dual-pane windows with quality frames reduce outside noise. If you're near a busy road in Lake Mary, you'll notice the difference right away.
