Egress Window Buying Guide

An egress window is more than just a feature; it's a critical safety component, required by building codes throughout Canada and the U.S. This comprehensive guide explains what egress windows are, helps you determine if your home needs one, and guides you through selecting the right window, understanding costs, and installation considerations.

What is an Egress Window?

Egress windows are emergency exit windows that are large enough for an adult to escape through in an emergency. They're mandatory for basement living areas and all bedrooms unless a sprinkler system is installed. Check your local building department or consult local codes for specific requirements in your area.

Egress Window Code Requirements

The National Building Code of Canada (NBCC) specifies:

• Minimum net clear opening of 3.77 square feet (0.35 m²).

• Minimum opening height and width of 15 inches.

• Maximum sill height of 1 meter from the floor.

These are general guidelines. For specific regional or municipal requirements, we offer detailed guides for various localities. Click our menu dropdown to see the various regions across Canada.

Choosing the Right Egress Window

Egress windows come in various styles, some of which include casement, sliding, side-hinge, and tilt & turn. Our side hinge and reverse hopper styles are built to meet code and are optimal because they:

1. Have a large clear opening to frame size.
2. Are in-swing, requiring less projection size for window wells.
3. Are super user friendly, equipped with a simple handle.
4. Are openable only from the inside, ruling out the need for a locking mechanism (required by code).
   
5. Won't break the budget.

The European tilt and turn style is another style commonly used for egress. You may choose it if you:

1. Are willing to spend a little extra.
2. Would like the dual "tilt" and "turn" functionality, which promotes either airflow or opening.
3. Value the in-swing functionality and large clear opening proportions (like the side hinge/reverse hopper).
4. Need a larger window (hinges are stronger and can support larger sash).

Costs of Egress Windows

Window installation costs vary significantly depending on whether you require:

• Simple window replacement only.

• Complete installation including excavation, window well installation, and drainage.

Typical costs can range widely:

• Vinyl egress windows: $350 - $1500 (window only - depending on size and style)

• Full basement installation (window, well, drainage, excavation): $5,000+ depending on complexity and region.

For precise estimates, it's best to consult with local professionals.

Permits

Because an egress window installation can impact your home's structural integrity, safety, and compliance with building codes, most municipalities require you to apply for and obtain a building permit.

Why Permits Are Important:

• Safety: Ensures the window meets safety standards.
• Code Compliance: Prevents costly fines or repairs later.
• Resale Value: Ensures the upgrade is recognized by home inspectors and future buyers.
• Insurance: Ensures coverage in case of future claims related to your home's structural modifications.

Steps for Permit Application:

1. Consult local building department (or municipal office).
2. Submit detailed plans/drawings of the installation.
3. Pay required permit fees.
4. Schedule inspections (typically required before completion).
5. Complete final inspection to ensure compliance.

Rules and steps may vary depending on your location.

Installation Steps

Egress window installation can be complex, especially when concrete cutting or excavation is required. Steps typically include:

1. Installing the window well.

2. Cutting the foundation.

3. Framing the rough opening.

4. Installing and finishing the window.

If unsure, always hire a professional installer to ensure safety, structural integrity, and code compliance.
