  • Clean removal — no damaged stucco, drywall, or trim
  • Proper flashing, foam, and weatherseal at every opening
  • Old windows hauled away and recycled
  • Walkthrough & warranty review before we go

Old aluminum sliders were leaking heat and noise for years. The crew finished 11 windows in a single day — protected the floors, hauled the old units away, walked us through the warranty. The house is noticeably quieter and the furnace barely runs now. Worth every penny.

We got three quotes for a whole-home replacement. Sunbusters wasn’t the cheapest, but they were the only ones who actually measured every opening and explained the spec — argon fill, low-E, frame depth. Install was spotless. No surprise charges at the end.

Fogged glass on the main floor for two winters running. They replaced six sealed units, no fuss, warranty handled it from start to finish. Showed up when they said they would. Would absolutely call them again — and have recommended them to two neighbours since.

Common questions

Calgary window replacement FAQ.

How do I know if I need to replace my windows?
Common signs: drafts you can feel near the frame, fogging or moisture between panes, hard-to-open or stuck sashes, peeling paint or rotting wood, and rising heating bills. If two or more sound familiar, it’s usually time.
Are triple-pane windows really worth it in Calgary?
In Calgary’s climate — yes. Triple-pane with argon and low-E typically cuts heat loss 30–40% versus double-pane and noticeably reduces street noise. For north-facing rooms and bedrooms above garages, the comfort difference is the bigger win.
How long does a typical window replacement take?
Manufacturing runs 2–3 weeks after you sign. The install itself is one day for most homes — typically 8–12 windows in 6–8 hours. Whole-home jobs with 20+ openings may take two days.
Can you replace windows in winter?
Yes. We replace one or two openings at a time so your home stays warm. Modern sealants are rated to install below 0 °C, and most homeowners don’t feel a temperature change inside.
Should I replace one window or the whole house at once?
If 80% of your windows are the same age, doing them together is cheaper per window — fewer mobilizations, one warranty start date, and the 50% off install applies to every opening on the same contract.
Do new windows include a warranty?
Yes — manufacturer’s lifetime warranty on the window units, plus our written 5-year installation warranty. We’re still here in Calgary, so warranty service is a local phone call.
What does the 50% off offer apply to?
50% off the installation labour portion of your quote, on every window in a contract signed by June 30, 2026. No fine print on the windows themselves — same units, same warranty.
