An egress window installation in Toronto costs $4,500 to $8,000, and at Egress Window Pros Toronto that total covers the complete job: cutting the foundation opening, the egress-compliant window, a new window well, drainage, waterproofing, backfill, and trim — not a bare window and a hole. The price swings based on three things: whether the existing opening can be reused or must be enlarged, whether the foundation is poured concrete or block, and how deep the window well has to be to meet Ontario Building Code 9.9.10.1 exit clearances.
What's Included in the Price
Most cost guides you'll find online quote a window and a rough opening. That's not a finished egress — that's a start. Our price includes the whole installed system, and the number we give you in writing is the number you pay. No hourly billing, no surprise additions.
Standard scope:
- Egress-compliant window (casement or slider) sized to meet OBC 9.9.10.1 opening requirements
- Cutting and enlarging the foundation opening, with a steel lintel installed where structural support requires it
- Steel or aluminum window well sized to the required depth and ground projection
- Gravel base and drainage — tied into the weeping tile or a dedicated French drain
- Exterior waterproofing membrane around the new opening
- Interior and exterior trim, caulking, and finishing
- Removal and disposal of the old window, well, and debris
- A job that's ready for inspection and signed off under the Ontario Building Code
What pushes the price to the higher end:
- Relocating the window. Moving the window means new structural and framing work, not just cutting a bigger hole.
- Deepening the window well. Older homes in this area often have high sills; meeting the OBC sill height clearance means the window well has to sit deeper below grade.
- Adding a cover. A cover keeps out leaves, critters, and pooling water: $300 to $900 depending on size and material.
- Fixing drainage first. If the area already takes on water, that needs to be solved before the egress goes in, or you'll be pumping out your new window well every spring. That work runs $500 to $3,000.

Permit fees are separate and paid to the municipality. An egress window requires a building permit, and the work has to comply with the Ontario Building Code. We prepare the permit drawings, file the application, and coordinate inspections as part of the installation — you don't need to become an expert in municipal permitting to get this done right.
The cheapest quote is rarely the cheapest outcome. An undersized window well or a drainage tie-in that got skipped shows up in year one, not year ten. The ranges above are what a code-compliant, properly drained install actually costs.
How Installation Works
Step 1: Free site evaluation. Call us and we'll visit within 48 hours. We measure the window, assess the foundation type, check the exterior grading, and confirm whether the existing opening will work or needs to be enlarged. We also look at drainage before we quote — because a cheap egress that drains wrong is a future problem, and we'd rather price it properly upfront.
Step 2: Written fixed-price quote. Within two days of the site visit you have a written number. If the scope doesn't change, the price doesn't change.
Step 3: Permit and prep. We draw up the permit package and handle filing and inspection scheduling. You pay the municipality's fee. We handle the rest.
Step 4: Installation. Most jobs take one to two days. Day one is the heavy work: cutting the opening, installing the window, setting the window well, and connecting the drainage. Day two covers backfill, waterproofing checks, and finishing. Because clay soil and constant freeze-thaw cycles wreck undersized drainage, our drainage spec is designed for the region — not a layer of gravel and good intentions.
Step 5: Inspection and warranty. The work gets inspected and signed off under OBC 9.9.10.1, and it's covered by a 10-year workmanship warranty.
Why Choose Egress Window Pros Toronto
We're a family-run basement contractor with 12 years of below-grade work and more than 400 egress windows and window wells installed in established neighbourhoods.
Code compliance is the baseline, not the upsell. Every egress we install meets OBC 9.9.10.1 exit requirements — window size, sill height, and window well clearance. We don't build to "close enough," because a failed inspection is a waste of your time and money.
We work year-round. February installs are business as usual. The difference isn't the season — it's whether the drainage design handles frost and snowmelt. Ours does.
Licensed, insured, and WSIB covered. It doesn't matter until something goes wrong, and then it matters completely.
The warranty doesn't expire when the invoice does. Ten years on workmanship, and we're a local company that will still be here to honour it.
