Egress & Basement Window Replacement in Kitchener

Why egress windows matter
If you're finishing a basement to add a bedroom or a legal rental unit, the Ontario Building Code requires an egress window — an opening large enough for an occupant to escape a fire and for a firefighter to get in. It's not optional. Skipping it can fail inspection, void insurance, and put your family at risk. Always confirm current requirements with the City of Kitchener before you build.
What a compliant egress install includes
- Confirming the code-required opening size for your application
- Cutting and enlarging the foundation opening as needed
- Installing a properly sized, easy-to-open window
- Building an exterior window well with proper drainage
- Sealing and finishing for a dry, draft-free basement

Egress & basement windows: FAQ
Do I need an egress window for a basement bedroom in Ontario?
Yes. Under the Ontario Building Code, every basement bedroom must have an egress window (or door) large enough for someone to escape and for a firefighter to enter. If you are finishing a basement to add a legal bedroom or rental unit, an egress window is required. Always confirm current requirements with your municipality.
How much does an egress window cost in Kitchener?
Egress and basement windows cost $2,000 to $3,800 installed in Kitchener. The price reflects the larger opening, exterior excavation, and window well often required. See our cost guide.
What is the minimum size for an egress window?
The Ontario Building Code sets minimum opening dimensions for egress windows (generally an unobstructed opening of at least 0.35 m² with no dimension less than 380 mm). Requirements can vary by application, so we confirm the exact code specs for your project before installing.
Does installing an egress window require excavation?
Usually yes. Enlarging a basement opening to code size typically means cutting the foundation and adding a window well outside. Our crew handles the excavation, cutting, window install, and well — all in the quote.
