An egress window in a Toronto basement meets Ontario Building Code exit requirements while adding natural light and legal bedroom status, but only if it's engineered and installed correctly. Code compliance, leak prevention, permits, and safety all come down to the same thing: proper below-grade work, done by people who have dug in Toronto's clay soil and designed drainage for its freeze-thaw cycles.
What an Egress Window Installation Includes
Every standard installation from Egress Window Pros Toronto covers:
- Excavation of the exterior wall down below the window opening, with soil sloped away from the foundation
- Cutting and removal of the concrete foundation wall inside the window well
- Installation of a compliant egress window (minimum 0.35 m² clear opening, minimum 380 mm wide and 450 mm high, sill no higher than 1000 mm from the finished floor)
- Gravel backfill and a weeping tile drainage line connected to your sump pit or exterior drainage
- Sealed window-well joints and a waterproofing membrane on the well wall
- Optional window well covers, grates, and liners
Every install is designed around OBC 9.9.10.1 exit requirements, so the room below can be legally called a bedroom and pass a resale inspection. We also document the final opening dimensions so you have the paperwork when it comes time to sell.
Egress Window Pricing in Toronto
Pricing depends on wall thickness, depth below grade, soil conditions, and whether you need drainage upgrades. These are the typical ranges we see across the GTA:

The quote is fixed after the site evaluation, no hourly surprises. If we hit buried concrete or an unexpected utility line, we stop and call you before spending another dollar.
The Installation Process
1. Free site evaluation within 48 hours. We measure the opening, check the foundation, assess drainage, and flag any permit or setback issues.
2. Permit handling. Toronto requires a building permit for cutting an exterior wall. We include the drawings, file the application, and book the inspection.
3. Installation. Excavation, concrete cutting, window set, well set, drainage hookup, and restoration, typically 2–3 days total.
4. Inspection and warranty. You get the OBC compliance paperwork, and every install carries a 10-year workmanship warranty.
We work year-round. This region's freeze-thaw cycle is exactly why winter installations need deeper drainage and careful backfill, that is standard practice for us, not an upsell.
