Replacing windows and doors is one of the most impactful home improvements for Canadian homeowners — improving energy efficiency, comfort, security, and curb appeal all at once. With Canada's cold winters, drafty or failing windows can cost hundreds of dollars extra per year in heating. This guide covers costs, options, and available grants.

Average costs in Canada 2025:
Standard double-hung window (installed): $500–$1,200 per window
Casement window (installed): $600–$1,500 per window
Large picture window (installed): $800–$2,500
Entry door (installed): $1,500–$4,000
Patio/sliding door (installed): $2,000–$6,000
Full house (100–15 windows + 2 doors): $10,000–$25,000

Door Replacement Costs

Entry Doors ($1,500–$4,000 installed)

A new entry door dramatically improves curb appeal and security. Steel entry doors are the most popular in Canada for security and insulation. Fibreglass doors mimic wood grain but don't rot or warp. A basic steel door with installation: $1,500–$2,500. A premium fibreglass entry door with sidelights: $3,000–$6,000+.

Patio/Garden Doors ($2,000–$6,000 installed)

Sliding patio doors: $2,000–$4,000 installed. French doors (hinged): $3,000–$7,000 installed. Triple-pane glass significantly improves energy performance in Canada's climate and is worth the premium in colder regions (Alberta, Saskatchewan, northern Ontario).

Interior Doors ($200–$600 per door installed)

Interior doors are far less expensive — typically $200–$400 for a hollow-core door and $400–$800 for solid core, including installation.

Energy Efficiency: What to Look For

For Canadian climates, look for windows with:

Canada Greener Homes Grant for Windows

The Canada Greener Homes Grant provides up to $250 per window and up to $250 per sliding glass door for ENERGY STAR-certified replacements, with a total maximum of $5,000 for windows and doors combined. To access the grant, you must:

  1. Complete a pre-retrofit EnerGuide home evaluation
  2. Install eligible ENERGY STAR-certified windows/doors
  3. Complete a post-retrofit EnerGuide evaluation
  4. Submit your claim with invoices through the federal portal

The grant can significantly offset the cost — on a $15,000 window replacement project, $5,000 in grants brings your net cost to $10,000.

Retrofit vs. Full-Frame Replacement

Retrofit installation (insert fit) slides a new window into the existing frame and is less disruptive and less expensive — ideal when the existing frame is in good condition. Full-frame replacement removes everything down to the rough opening and is necessary when the frame is rotted, damaged, or you want to change the window size. Full-frame costs 200–400% more but provides a clean, long-lasting installation.
