Out With the Old, In With the NeW

If your windows are more than 15 or 20 years old, you can usually feel it before you see it — cold drafts near the glass, rooms that never quite get warm, condensation in the morning, sunlight that's lost its sparkle. Replacing those tired windows isn't just a cosmetic upgrade — it's one of the highest-impact home improvements you can make for comfort, energy savings, and resale value.

At Summit, we make replacement straightforward. Old units carefully removed. Openings prepped properly. Brand-new Vinylguard windows custom-built to your exact measurements and installed clean. And we don't ask for a cent on projects under $20,000 until you're completely happy with the result.

Signs It's Time to Replace Your Windows

Not sure if your windows are due for replacement? Most homeowners notice one (or several) of the following before they call us.

Cold Drafts and Cold Rooms

You can feel air movement near the window even when it's closed. Some rooms never quite warm up in winter no matter how high the thermostat climbs.

Fogging or Condensation Between Panes

Moisture trapped between the glass panes means the sealed unit has failed — and once it fails, no amount of cleaning or weatherstripping will bring back the insulating value.

Sticky Sashes and Broken Hardware

If windows are painted shut, cracked, warped, or won't lock properly, they're not just frustrating — they're a safety and security concern.

Rising Heating and Cooling Bills

When your monthly bills keep climbing despite a sealed home and decent thermostat habits, your windows may be quietly leaking your hard-earned dollars to the outside.

New Vinylguard windows pay you back in four different ways — every season, every year, for the life of your home.

The Return on Replacing Your Windows

Real, Measurable Energy Savings

Natural Resources Canada estimates Energy Star window upgrades save the average home 8% on energy bills. LowE glass, argon-filled sealed units, and warm-edge Super Spacer technology come standard on every window we install.

Curb Appeal That Sells

Fresh, modern windows transform a home's exterior more dramatically than almost any other upgrade. With 20+ standard colours and unlimited custom shades, we can match your existing trim — or give your home an entirely new look.

Comfort You Notice Every Day

No more cold spots, no more sun-faded furniture, no more rattling on windy nights. Triple weatherstripping, multi-chambered frames, and tight-tolerance manufacturing mean a home that simply feels better year-round.

Lifetime Warranty That Transfers

Vinylguard's non-prorated, fully transferable Lifetime Warranty is one of the strongest in the industry. When you eventually sell, that warranty travels with the home — adding negotiating power and real value at closing.

Window Styles for Every Replacement Project

Whatever you're replacing — a single basement slider, a row of bedroom casements, or every window in the house — we install the full Vinylguard lineup, custom-built to your existing openings.
