Window Replacement Toronto & the GTA
European-engineered replacement windows, supplied and installed across Toronto, Vaughan, and the GTA. Triple-glazed, tilt-and-turn, Uw ≤ 0.80 — built for Ontario winters.
Replacing windows in Toronto is a performance decision, not just a cosmetic one.
Every winter, a typical Toronto home with builder-grade windows loses up to 25% of its heating energy through the glass and frames. Replacing those windows with high-performance European units is one of the most effective envelope improvements available.
We supply replacement windows manufactured in Europe and specified for Ontario's climate: triple-glazed tilt-and-turn systems with Uw ≤ 0.80 W/m²·K — roughly 2× better than standard North American double-pane units.
Five signs your windows need replacing.
Drafts you can feel
Cold air pooling near windows in winter means failed seals or poor frame design. Modern European units are tested for airtightness at the full-unit level.
Condensation between panes
Fog between the glass means the seal has failed and the insulating gas has escaped. That window is now just two sheets of glass — no better than a single pane.
Frost on the interior
Interior frost means the frame itself is a thermal bridge. PHI-certified units maintain interior surface temperatures above 17°C even at −10°C outside.
Sticking or hard-to-operate sashes
Warped frames and seized hardware are signs of end-of-life. Tilt-and-turn hardware is engineered for decades of daily operation.
Rising energy bills
If your heating costs climb year over year with no change in usage, your envelope is leaking. Upgrading to Uw ≤ 0.80 cuts window heat loss by roughly half.
Noise you can't ignore
Traffic and city noise penetrate double-pane glass easily. Triple-glazed European units with acoustic laminated glass dramatically reduce sound transmission.
What does replacement actually cost?
In the GTA, window replacement typically runs $800–$1,400 per opening installed for high-performance triple-pane systems — $1,200–$2,000 for Passive House certified units. We've published a full breakdown of 2026 pricing, energy savings, and payback periods for Toronto homes.
