Egress Window Installation in Vaughan, ON | OCM Excavation

OCM Excavation handles code-compliant egress window installs across Vaughan — Maple, Kleinburg, Woodbridge, Concord, and Thornhill. We do the full job: exterior excavation, foundation saw-cut, steel lintel, waterproof sill, window install, and window well with proper drainage. Most Vaughan calls are estate bungalows in Maple and Kleinburg or older Woodbridge homes getting prepped for legal-suite use, where the original basement openings fall short of Ontario Building Code 9.7.1.3 and 9.9.10. Call 416-317-3090 to book a Vaughan site visit.

What the Code Says About Egress

If a basement room is going to be used as a bedroom, the Building Code requires an emergency escape window: minimum clear opening of 0.35 square metres, no dimension less than 380 mm, sill no more than 1.5 m above the finished floor, and the unit has to open from inside without keys, tools, or special knowledge. The old hopper windows in a 1970s Woodbridge basement do not pass. The structural fix is to cut the foundation and install a real egress unit.

How an Egress Install Goes Together

Exterior excavation — Yanmar SV40 digs 24 to 36 inches below grade, 12 inches past the planned window perimeter. We work tight around interlock, irrigation lines, and the mature landscaping common on Vaughan estate lots.
Foundation cut — concrete saw scores the cut, then we hammer-drill or chain-saw out the section. Any opening wider than 36 inches needs an engineer-stamped lintel design.
Steel lintel and waterproof sill — load-bearing steel above the opening, sealed sill at the bottom.
Window install — egress-sized sliding or casement, typically 36″×48″ or 36″×60″, set in waterproof flashing.
Window well and drainage — see our Vaughan window well installation page. Clean stone, drainage tied into the weeping tile.

Vaughan Permits and the Lintel Question

Vaughan’s Building Standards department issues a building permit for the foundation cut and window opening. If the egress is part of a second-suite legalization, a zoning compliance review will normally run alongside the structural permit. Confirm the current process directly with the City before scheduling — Vaughan updates its second-suite policy and submission requirements periodically. Most poured concrete foundations in Vaughan can take a standard egress cut with a properly sized lintel. Block foundations in older Woodbridge homes sometimes need extra reinforcement, and your engineer will call that.

Pricing and Timeline in Vaughan

Most Vaughan egress installs land in the $3,500 to $7,500 range per opening. The big variables are foundation type, depth of dig, window size, soil conditions, and the drainage tie-in. Per opening, expect 5 to 10 working days from first dig to backfilled and inspected. Estate bungalows in Kleinburg with hard side-yard access or heavy landscaping to protect run slower; Concord builds with poured walls and clear access wrap quickly.

Pairing Egress with Walk-Ups and Underpinning

Vaughan legal-suite jobs frequently combine egress with a separate entrance. A Vaughan walk-up basement conversion shares mobilization and excavation with the egress dig, so doing them together saves on cost and time. If the basement ceiling is short and you need more headroom, we sequence egress into a Vaughan basement underpinning schedule. One excavation crew, one engineer file, one closure inspection where possible.

Why Vaughan Owners Pick OCM

We are excavation and foundation specialists. The dig, the cut, the well, the drainage, the waterproof finish — that is the whole job in our shop. We coordinate cleanly with your designer’s engineer and we leave the opening square and dry so the window installer just sets the unit.

Frequently Asked Questions

Does Vaughan require a permit for egress?

Yes. Vaughan Building Standards requires a building permit for any structural opening cut into a foundation wall. If the install is part of a second-suite project, expect a zoning compliance review alongside. Your designer submits engineer-stamped drawings with the permit application.

Can you fit a full-sized egress in a Woodbridge bungalow basement?

Almost always, yes. The 1960s and 1970s Woodbridge bungalows have foundation walls that take an egress cut cleanly. The trickier part is sometimes the sill height inside — if the basement floor was raised during a previous renovation, your designer may need to drop the window or rework the floor. We check during the site visit.

How big does the window well need to be?

The well has to allow the window to fully open and someone to climb out. The Building Code sets minimum well dimensions, and the actual size also depends on window dimensions and grade. We pick a galvanized or polymer well sized to your specific opening and tie the drainage to your weeping tile.

Will the work compromise my foundation’s structural integrity?

Not when the lintel is engineered and installed properly. The steel lintel transfers the load above the opening down through the remaining wall sections. Your engineer specifies the lintel size, and we install to that spec. Cuts wider than 36 inches always need engineering.

Typical Vaughan price?

$3,500 to $7,500 per opening for excavation, cut, steel lintel, egress window, and basic window well. Pricier on deep digs, wider openings, or where drainage needs to run further to tie into the weeping tile. We give you a firm number after seeing the site.
