What Factors Affect the Cost of Window Replacement?

The framing material is one of the primary factors affecting how much window replacement costs. Vinyl is usually the cheapest option, costing between $100 and $850 (CAD 140 and CAD 1,200) per window. Installing wood-framed windows costs between $200 and $1,000 (CAD 275 and CAD 1,400), while fiberglass-framed units cost between $150 and $1,400 (CAD 200 and CAD 1,950).

Other factors impacting the cost of replacing your windows may include the following:

Single Vs. Double Panes

Single-pane windows are significantly more affordable than those with double panes. However, they're rarely used in modern homes because they're inefficient and provide minimal insulation. Replacing a single-pane window typically costs between $290 and $460 (CAD 400 and CAD 640), while replacing a double-pane window costs between $450 and $1,000 (CAD 625 and CAD 1,400).

House Age

You could spend much more replacing windows in an older home than in a modern building. Replacing a window in a period property costs between $800 and $3,000 (CAD 1,100 and CAD 4,200) per unit. It could cost even more if you require custom-made units.

Frame Condition

If your window frames are broken or rotten, you'll need to install full-frame windows. These windows come in standard sizes and include a frame. Full-frame windows usually cost between $150 and $1,000 (CAD 200 and CAD 1,400) installed.

However, you could consider installing retrofit windows if your frames are in good condition. Retrofitting a window involves replacing the glass while retaining the existing frame. Retrofit replacements are much more affordable, costing around $100 to $300 (CAD 140 and CAD 415) installed.

Energy Efficiency

Energy-efficient windows are more expensive than standard windows, but they could save you a significant amount on your heating bills. They minimize heat transfer to keep your home warm in the winter and cool in the summer, and many models block UV rays that could damage your furniture, wallpaper and floor coverings.

The federal government operates a tax credit system to subsidize the cost of installing Energy Star-rated windows by up to 30%. Combined with energy savings, claiming tax credits could make installing efficient windows more affordable long term.

What's the Average Total Cost of Replacing Windows?

The average total cost of replacing all the windows in your home depends on your home's size and the number of windows. According to Fixr, most homeowners spend between $9,000 and $24,000 (CAD 12,200 and CAD 32,600) to replace 20 windows in a typical family home.
