How much do egress windows cost to install in a Vancouver basement?

Egress window installation in a Vancouver basement costs $3,000 to $8,000 per window, including the window unit, cutting the foundation wall, installing the window well, and all associated structural and waterproofing work. If your basement has bedrooms — or if you plan to add bedrooms — egress windows are not optional. The BC Building Code requires every basement bedroom to have an egress window with a minimum unobstructed opening of 0.35 square metres, a minimum width of 380 millimetres, and a maximum sill height of 1,100 millimetres from the finished floor.

The cost breaks down into several components. Cutting the foundation wall is the most labour-intensive part — a concrete cutting crew uses a diamond-blade wall saw to create the opening in your poured concrete or concrete block foundation. This typically costs $1,500 to $3,000 depending on wall thickness, the size of the opening, and access conditions. A structural engineer may need to design a lintel or header above the opening to maintain the foundation's load-bearing capacity, especially in BC's seismic zone where earthquake loading must be accounted for. Engineering for a window opening runs $500 to $1,500.

The window unit itself costs $400 to $1,200 for a quality egress-compliant casement or sliding window. Casement windows are the most popular choice for basement egress in Metro Vancouver because they swing fully open, providing the maximum unobstructed opening for emergency exit. Hopper windows — the type that hinges at the bottom and tilts inward — generally do not meet egress requirements because the opened sash obstructs the clear opening. Make sure your window is specifically rated for egress compliance before purchasing.

The window well is a critical component that is often underestimated in Metro Vancouver projects. A prefabricated galvanized steel or polyethylene window well costs $200 to $600, but the excavation, gravel drainage bed, and connection to your perimeter drainage system can add $500 to $2,000 in labour and materials. In Vancouver's climate, drainage in the window well is absolutely essential — without it, the well becomes a collection basin for rain that eventually leaks through or around the window frame. A proper window well drain connects to your weeping tile or has its own dedicated drain line. A clear polycarbonate window well cover ($100 to $300) keeps out debris and most rainfall while still allowing light and emergency egress.

Homeowners sometimes ask whether they can enlarge an existing small basement window to meet egress requirements rather than cutting a new opening. This is often possible and can save $500 to $1,500 compared to a completely new opening, since part of the wall has already been cut. However, enlarging still requires concrete cutting, structural assessment, and possibly a new lintel, so the savings are moderate.

Installing an egress window requires a building permit from your municipality because you are modifying a structural element of the foundation. The work involves concrete cutting (specialized contractor), structural engineering, waterproofing, and exterior excavation — this is definitively professional work, not a DIY project. Your contractor must carry WorkSafeBC coverage, and the installation will be inspected by the municipal building department.

Beyond code compliance, egress windows transform basement spaces by bringing in natural light — a significant benefit in Vancouver's dark winter months when daylight hours are short. A well-placed egress window can make a basement bedroom feel like a genuine living space rather than a cave. If you are finishing your basement and plan any sleeping areas, budget for egress windows from the start.
