Common Questions

In 2026, Ottawa homeowners can expect to pay between $600 and $2,000 per window unit installed, depending on the size and frame material (vinyl vs. fiberglass).

Yes, the Home Renovation Savings Program remains active until November 2026, offering a rebate of $100 per window for high-efficiency upgrades.

Triple-pane windows typically carry a price premium of 20% to 30% over double-pane units, but they are highly recommended for Ottawa's extreme winter temperatures to reduce heat loss.

A full-frame replacement, which involves replacing the entire window and trim, costs approximately 15% to 20% more than a retrofit (insert) installation, which reuses the existing frame.
