Egress Window Cost Calculator

An egress window installation in Toronto costs $4,500–$8,000 fully installed, with the final price driven mostly by excavation depth, foundation type, window size, window-well material, and drainage conditions. That range covers the complete job: cutting and removing concrete, installing an Ontario Building Code–compliant window (minimum 0.35 m² opening, minimum 380 mm dimension), excavating and installing a window well, connecting drainage, backfilling, and cleaning up. If you only need a window well, cover, or drainage repair, expect $300–$3,000 depending on scope — full breakdown below.

What's Included in a Full Egress Window Installation

A real egress window isn't just "a window in a hole." In Toronto, a basement bedroom needs an opening that a person can actually escape through, plus a window well that doesn't trap water. Here's what a complete installation includes:

• Free site evaluation and measurements — done within 48 hours of your call
• Excavation down to the window opening — hand dig or mini-excavator, depending on access
• Concrete sawing and removal for the new opening
• Rebar cutting and foundation-edge preparation
• Egress window installation — casement or slider, tempered glass, screen included
• Window well installation — steel, aluminum, or polymer
• Drainage connection — gravel bed, sump, or tie-in to the weeping tile at the footing
• Backfill and compaction with clean fill
• Debris removal and final cleanup
• 10-year workmanship warranty on the installation

Not included unless requested: window well covers, interior insulation and framing, and exterior waterproofing membrane upgrades. These are common add-ons on older Toronto homes, and we quote them separately during the evaluation.

Egress Window Cost Breakdown

Here's how pricing breaks down for basement escape work across the GTA:

The $4,500–$8,000 egress range covers a finished, code-compliant installation on a typical Toronto basement: poured concrete or concrete block foundation, one storey below grade, and reasonable exterior access. The lower end is a straightforward job with decent soil, a clean work area, and a standard 36" x 42" opening. The higher end covers deeper basements, older block foundations, hand-dig-only access, heavy clay soil, or situations where a drainage sump and interior waterproofing are required.

Most Toronto quotes land between $5,000 and $6,500 for a standard job. If someone quotes you under $4,000, ask exactly what's excluded — usually it's the window well, drainage, or permit fees.

What Drives the Cost Up (and Down)

• Basement depth. Deeper below grade means more excavation, more backfill, and a taller window well. Every extra foot of depth adds roughly $300–$600.
• Foundation type. Poured concrete cuts cleanly. Older block foundations — common in Toronto neighbourhoods like East York and the Annex — take more time to prep and patch, which pushes the quote up.
• Soil and drainage conditions. Toronto's clay-heavy soil holds water and needs more drainage material. If downspouts are already funneling water behind the wall, expect drainage work to be part of the quote.
• Window size and style. A slider is cheaper than a casement of the same size, but some windows need a bigger well to open fully. Larger opening, larger well, higher cost.
• Access. If we can get a mini-excavator beside the house, you pay less labour than a hand-dig-only job with fence and landscaping obstacles.
• Existing window well condition. Replacing an undersized, rusted 1970s well avoids the cost of the window itself — you're paying mostly for demolition, replacement, and drainage.

Our Process

1. Free site evaluation. We visit your Toronto home, inspect the wall from inside and out, measure the opening, check the soil, and confirm access. You get a written quote within 48 hours.

2. Details locked down. We confirm window size, well material, drainage plan, and exactly what's included. We also flag permit requirements and OBC 9.9.10.1 compliance.

3. Excavation and cutting. We expose the foundation, saw-cut the opening, and prep the edges.

4. Window and well installation. The window goes in, the well gets anchored, and drainage gets connected to the weeping tile or gravel bed.

5. Backfill and cleanup. The open cut is backfilled, compacted, and the site is cleaned.

6. Walk-through. We show you the opening, the drainage connection, and how the system sheds water.

Winter doesn't stop us. During Toronto's freeze-thaw cycle, we use gravel drainage beds and controlled backfill so the well doesn't heave come spring.
