How much does a window opening in a concrete wall cost in Ottawa?

2026-01-15 — Ottawa-Gatineau

It's THE question we get asked most. Short answer: between $500 and $1,500 for cutting a standard window opening in a poured concrete foundation in Ottawa-Gatineau. Here's what moves the price.

Price factors

1. Wall thickness and type

An 8" poured foundation cuts faster than a 10" or 12" reinforced wall. Concrete block is often the cheapest to open. Stone (older downtown Ottawa or Hull homes) takes longer.

2. Opening size

A code-compliant egress window is roughly 30" × 48" — the bigger the opening, the more concrete to cut and haul out. The removed block often weighs several hundred pounds.

3. Accessibility

Clear workspace outside = faster = cheaper. A sloped yard, a deck above the window, or landscaping to protect adds time.

4. Possible extras

• Steel lintel (required for wide openings): +$150 to $400
• Excavation and window well: usually a separate contract
• The window installation itself: done by a window installer, not the cutter

How to save

• Bundle the work: two windows the same day cost less than two visits
• Clear access before the contractor arrives
• Send photos with your quote request — avoids price surprises
