What's the cost of window well installation for egress windows in Metro Vancouver?

Window well installation for egress windows in Metro Vancouver typically costs $3,000 to $8,000 per window, with the total depending on the depth of excavation, foundation cutting, window well material, and drainage requirements. This is one of the most important investments in a basement finishing project — the BC Building Code requires every basement bedroom to have an egress window, and in Vancouver's rainy climate, the window well must be properly drained to prevent water from pouring into your finished space.

The cost breaks down into several components that vary based on your specific situation. Foundation cutting is the most labour-intensive part — a concrete saw cuts through the poured concrete or concrete block wall to create or enlarge the opening. For a standard poured concrete foundation (8 to 10 inches thick), cutting and forming the new opening runs $1,500 to $3,000. This work requires a structural engineer's review ($500 to $1,500 for the assessment and detail drawing) to ensure the opening does not compromise the foundation's load-bearing capacity. In BC's seismic zone, the engineer must also verify that the modified wall can handle earthquake forces, which may require additional steel lintels or reinforcement above the opening.

The window well itself — the corrugated steel, fibreglass, or precast concrete enclosure installed outside the foundation — costs $300 to $1,200 for materials depending on size and type. Corrugated galvanized steel is the most common and affordable option at $300 to $600. Fibreglass and composite wells cost $500 to $900 and resist corrosion better in Vancouver's wet environment. Custom precast concrete wells for larger openings or walk-out configurations run $800 to $1,200. Installation requires excavation around the foundation wall, placement and anchoring of the well, and backfilling with clean drainage gravel — labour for this runs $500 to $1,500.

Drainage is absolutely critical in Metro Vancouver, and this is where many installations fail. The window well must have a gravel base at least 6 inches deep connected to the perimeter drainage system (weeping tile) or a dedicated drain line. In areas with high water tables — Richmond, Delta, and low-lying parts of Surrey — the window well drain should connect directly to the sump pump system. Without proper drainage, a Metro Vancouver window well becomes a swimming pool during the rainy season, with over 1,200mm of annual rainfall pushing water directly through your new egress window. Budget $500 to $1,500 for drainage connection, more if the existing weeping tile needs repair or replacement.

The egress window unit itself costs $400 to $1,500 depending on type and size. The BC Building Code requires a minimum unobstructed opening of 0.35 square metres with a minimum width of 380mm and a maximum sill height of 1,100mm from the finished floor. Casement windows are the most popular choice for egress because they swing fully open to provide maximum clearance. Vinyl-framed, double-pane, argon-filled windows are standard in Metro Vancouver for energy efficiency. Slider windows can work if they meet the minimum opening dimensions, but casements are preferred by most inspectors and contractors.

A window well cover is an optional but highly recommended addition in Vancouver's climate. A clear polycarbonate cover ($150 to $400) keeps rain, leaves, and debris out of the well while still allowing light in and emergency escape out. The cover must not be locked or fastened in a way that prevents opening from inside — this is a life-safety requirement.

For pre-war character homes in Vancouver neighbourhoods like Kitsilano, Mount Pleasant, or Dunbar with stone or rubble foundations, egress window installation is more complex and expensive — budget $6,000 to $10,000 per window. Stone foundations require careful cutting and structural reinforcement that is more labour-intensive than working with poured concrete.

This is never a DIY project. Foundation cutting requires specialized equipment and structural engineering oversight, and the installation must pass municipal building inspection.
