How much does an egress window with well and cover cost in Calgary?

A complete egress window installation in Calgary — including the window unit, window well, cover, and professional installation — typically costs between $2,500 and $6,000 per window. The wide range reflects differences in foundation type, window quality, well size, and whether your home already has a rough opening or requires a new cut through the foundation wall.

Here's how those costs break down in the current Calgary market. The egress window unit itself runs $400 to $1,200 depending on whether you choose double-pane or triple-pane glass, vinyl or fibreglass frame, and casement versus sliding style. Triple-pane with Low-E coatings and argon fill is the recommended choice for Calgary's Climate Zone 7A, adding roughly $200-$400 over a basic double-pane unit but delivering meaningful energy savings when winter temperatures hit -30 degrees Celsius. The window well — typically a corrugated galvanized steel or HDPE liner — costs $150 to $400 depending on diameter and depth. A clear polycarbonate cover adds $100 to $300 and is essential in Calgary to keep snow, debris, and hail out of the well while maintaining emergency exit capability.

The labour component is where the biggest cost variation occurs. If your home already has an appropriately sized opening in the foundation (common in newer Calgary suburbs like Cranston, Evanston, or Mahogany where builders often include rough openings), installation runs $800 to $1,500 including the well excavation, gravel drainage base, and fitting. If a new opening must be cut through the foundation wall — necessary in most pre-2000 Calgary homes — the concrete cutting, structural steel lintel installation, and engineering add $1,500 to $3,500 to the project. Homes with concrete block foundations cost more to cut than poured concrete due to the risk of cracking.

Additional costs to budget for include the building permit ($200 to $500), gravel backfill and drainage connection to your weeping tile system ($200 to $500), and lot grading corrections around the well ($200 to $400 if needed). If your home has bentonite clay soil — common throughout Calgary's NW and NE quadrants — the excavation and backfill may cost more because the clay must be replaced with granular material to prevent water pooling.

For homeowners installing multiple egress windows as part of a full basement development, contractors typically offer per-unit pricing that decreases with volume. Two or three windows installed during the same project might run $2,000 to $4,500 each rather than the higher end of the single-window range, since the contractor mobilizes equipment only once. This is one of many reasons to plan egress windows as part of your overall basement development rather than as a standalone retrofit.
