Egress window installation in Mississauga typically costs $4,500–$8,000, and if you're finishing a basement bedroom or adding a secondary suite, Ontario Building Code 9.9.10.1 requires an egress window with a clear opening of at least 0.35 m² (3.77 sq ft) and no dimension under 530 mm. Egress Window Pros Toronto installs code-compliant egress windows and window wells across Mississauga — from Square One townhomes to older detached houses in Port Credit and Erin Mills — at the same rates we charge across the GTA.
Egress Windows in Mississauga: What's Included
Every egress window installation in Mississauga includes:
- Window rough-in and framing sized to meet OBC 9.9.10.1 exit dimensions
- Egress window unit (casement or slider) with a clear opening of at least 0.35 m²
- Window well installation with minimum 900 mm of clearance in front of the window
- Drainage stone and weeping tile around the well
- Window well cover with a secure locking mechanism
- Sealing, caulking, and interior trim
- Cleanup and debris removal
We also handle permit coordination or tell you exactly what Mississauga's building department will require before you call them. Permit fees are separate and typically run about $150–$400 depending on your ward.
Egress Window & Window Well Pricing in Mississauga
Mississauga pricing matches our GTA rates — we don't add a travel surcharge for working in the city. Typical ranges:
- Egress window installation: $4,500–$8,000 (deeper basements and poured concrete walls push the price up)
- Window well installation: $800–$2,500 (steel, aluminum, or corrugated)
- Window well covers: $300–$900 (polycarbonate or aluminum)
- Window well drainage and waterproofing: $500–$3,000
- Basement waterproofing (interior): from $1,200
- Window well replacement and repair: $500–$2,000
Every price quoted includes a free site evaluation. If a foundation crack or a failing weeping tile is feeding water into the well, we tell you before we quote — and we quote the fix fairly.
Our Mississauga Installation Process
Step 1 — Free site evaluation and quote within 48 hours. We visit your Mississauga home, measure the rough opening, check the exterior grade, and see how water moves around your foundation. You get a written quote.
Step 2 — Excavation and window well install. We excavate outside the window opening, set the well, and install drainage stone and perforated pipe so water moves away from the foundation — not into it.
Step 3 — Egress window installation. The window is set, leveled, shimmed, and sealed to the rough opening. It must open fully without resistance to pass inspection.
Step 4 — Waterproofing and backfill. We apply below-grade waterproofing membrane to the wall, then backfill in lifts, compacting as we go.
Step 5 — Cover and cleanup. The window well cover locks into place and the yard is left clean. Most installs take two to three days.
Because we work year-round, freeze-thaw cycles don't delay your project — our drainage design handles Mississauga's clay-heavy soil and wet springs.
