If you need an egress window installed in Oakville, Egress Window Pros Toronto handles the full job, from cutting the concrete foundation and installing a code-compliant window to excavating the window well and tying in drainage, for $4,500 to $8,000, with free site evaluations and quotes within 48 hours. We're a family-run Toronto basement contractor with 12 years of below-grade work and more than 400 egress windows and window wells installed across the GTA, including steady work throughout Oakville's older neighbourhoods where basement bedrooms were built before modern exit requirements existed.
What's Included in an Oakville Egress Window Installation
Every egress window install we do in Oakville meets Ontario Building Code 9.9.10.1 exit requirements. That means the finished opening is at least 0.35 m² (3.77 sq ft) with no dimension smaller than 380 mm (15 inches), and the sill sits no higher than 1,000 mm (39 inches) off the finished floor. We handle the entire scope:
- Concrete cutting and removal, diamond saw cutting through poured concrete or block foundation, with proper rebar cleanup and a clean, square opening
- Window supply and installation, welded vinyl or aluminum-clad windows sized to the rough opening, with low-E glass and a clear opening that meets OBC
- Window well excavation and installation, corrugated steel, aluminum, or polymer wells sized to the window opening, extending at least 760 mm (30 inches) from the foundation
- Drainage connection, weeping tile tie-in or a dedicated drainage layer with clear stone, so meltwater and rain don't pool in the well
- Backfill and grading, proper compaction and slope away from the foundation, which matters in Oakville's clay-heavy soils
- Interior finishing, we leave the rough opening ready for your drywall, or we can finish it for an additional cost
We also install window well covers ($300–$900), window well drainage and waterproofing upgrades ($500–$3,000), and basement doors ($2,500–$6,000) if you want direct yard access alongside your new egress.

Oakville homes built before the 1990s, especially in areas like Glen Abbey and older parts of Downtown Oakville, often have basement windows that are too small to qualify as egress. If you're converting a basement into a legal bedroom or rental unit, the window is non-negotiable. We'll tell you exactly what your home needs during the free site evaluation, and the quote is good for 90 days.
The Installation Process
Step 1: Free site evaluation. We come to your Oakville home, measure the existing window opening, check foundation thickness, assess soil and drainage, and confirm whether the location works for OBC compliance. You get a written quote within 48 hours.
Step 2: Permit and approval. Oakville requires a building permit for egress window work. We provide the drawings and specifications you need for the permit application, and we can coordinate with the building department on your behalf.
Step 3: Excavation. We dig out the window well area by hand or with a mini-excavator depending on access. In tight spots near Bronte Harbour, where older homes sit close together, hand excavation keeps damage to neighbouring properties at zero.
Step 4: Concrete cutting and window installation. We cut the foundation, install the window, and waterproof the rough opening. The window is anchored, shimmed, and sealed to prevent air and water infiltration.
Step 5: Window well and drainage. The well goes in, drainage is connected, and the backfill is compacted in lifts. We grade the soil away from the foundation so Oakville's freeze-thaw cycles don't heave the well or crack the drainage tile.
Step 6: Cleanup and inspection. We haul away all debris, leave the site clean, and schedule the final inspection so you have the paperwork for your permit close-out.
Most installations take 2–3 days from excavation to final grade. Year-round scheduling means we work through winter too, the drainage design handles Toronto's freeze-thaw pattern, and we've installed egress windows in Oakville in January without issues.
Why Oakville Homeowners Choose Us
We've installed egress windows and window wells across the GTA for over a decade, and we know the specific conditions Oakville presents. The soil here ranges from dense clay in Glen Abbey to sandy loam closer to the lake, and each requires a different drainage approach. Homes near Bronte Harbour often sit on older foundations with different block types, which changes how we cut and seal the opening.
- OBC compliant, guaranteed. Every install meets 9.9.10.1. If it doesn't pass inspection, we fix it at no cost.
- Licensed, insured, and WSIB covered. You're protected on every job, no exceptions.
- 10-year workmanship warranty. We stand behind the install long after the permit closes.
- Family-run, 400+ installs. This isn't a side hustle, it's our full-time trade, and we've done the work in hundreds of GTA basements.
- Transparent pricing. The quote you get is the price you pay. No surprise change orders unless you change the scope.
We also handle window well covers, drainage upgrades, basement waterproofing, and basement door installations in Oakville, so if you're planning a full basement renovation, you can bundle the work and save on mobilization costs.
