What Impacts the Cost of Window Replacement?

Here are the biggest pricing factors for GTA homeowners:

1. Type and Style of Window

Replacing a large bay or bow window costs much more than a simple casement or awning window.

2. Glazing and Energy Efficiency

  • Double-pane windows are standard, but triple-pane (great for cold GTA winters) can cost $150–$300 more per unit.

  • Add Low-E glass and argon gas fills for extra insulation and long-term savings.

3. Installation Type

  • Full-frame installation: Includes jambs, trim, and insulation. Costs more but addresses rot and air leaks.

  • Retrofit installation: Fits new windows into existing frames. Lower cost, faster install.

4. Frame Material

Vinyl is most popular in GTA—affordable, durable, and weather-resistant. Wood or fiberglass frames cost more but offer specific aesthetic or thermal benefits.

What Are the Different Styles of Windows?

Let’s go through what are the different window styles, and why it matters when budgeting for replacement.

Window Style How It Opens Best For
Casement Side-hinged, opens outward Bedrooms, living rooms
Awning Top-hinged, opens outward Bathrooms, basements
Double-Hung Two sashes slide vertically Bedrooms, traditional homes
Slider Sash slides horizontally Basements, kitchens
Picture Fixed, non-opening Living rooms, scenic views
Bay/Bow Multi-panel projection Dining rooms, front-facing rooms
Egress Code-required emergency exits Basements, bedrooms (legal)

What Is a Casement Style Window?

A casement window is hinged on the side and opens outward with a crank. It provides excellent airflow, a tight energy-efficient seal, and a clear view, making it one of the most popular window styles in GTA.

What Is an Awning Style Window?

An awning window opens from the bottom and is hinged at the top. It’s great for privacy, small spaces, and keeping rain out while the window are open. Perfect for basements and bathrooms.
