How much does window replacement cost in Calgary?

Kay2's 2026 cost guide puts replacing 12 to 18 windows on a Calgary home at about $22,000 to $55,000. For a single window, Canadian price guides in 2026 put a vinyl double- or triple-pane window at roughly $600 to $1,200 installed, with large, custom-shaped, fibreglass or wood-clad windows costing more.

Triple-pane glass typically adds about $100 to $300 per window over double-pane. In Calgary's winters, most homeowners find that worth it.

These are planning ranges, not quotes. A full-frame installation, a stucco house, upper-floor windows and fibreglass or wood-clad frames all push toward the top.

What changes the price

• The number and size of windows. Big living room windows and bays cost the most.
• Triple or double pane, low-e coatings and gas fill.
• Vinyl frames are the most affordable, fibreglass and aluminum-clad wood cost more.
• Casements and awnings cost more than fixed windows and sliders, but seal better.
• Insert or full-frame installation, explained below.
• Stucco walls need cutting and patching around a full-frame window, while siding can be removed and reinstalled more easily.
• Second- and third-storey windows may need scaffolding or a lift.
• Black and dark exterior frames cost more than white.

Double or triple pane in Calgary?

Triple-pane windows keep the inside glass warmer, which means less condensation and frost on cold days, more comfortable seating near the glass and often less street noise. In a climate where January nights regularly drop well below minus 20, that warmer glass is the main reason most Calgary homeowners choose triple pane.

Double pane with a good low-e coating and argon still performs well and costs less, and it can make sense on south-facing glass or in a home you plan to sell soon. Our guide to double or triple pane windows compares them in detail.

Insert or full-frame installation

If you are replacing siding or stucco at the same time, full-frame is the obvious choice, because the flashing can be done properly with the new wall. Our guides on siding replacement costs and stucco or siding cover the wall side.

Do you need a permit?

In Calgary, replacing a door, window or skylight with one of the same size does not need a permit. Making an opening larger or smaller needs both a development permit and a building permit, because a bigger opening needs a new header and can affect the look of the house from the street. Bedroom windows also have to meet egress rules for escaping in a fire, which matters most in basements. Our guide to egress window requirements has the sizes.

Will new windows lower your heating bill?

They help, but less than window salespeople often suggest. Windows are a small share of a house's wall area, and much of the heat loss in older Calgary homes comes from air leaks and thin attic and wall insulation. New windows make the biggest difference to comfort, condensation and drafts. If lower bills are the main goal, an energy assessment first will show where the money does the most good.

If you are combining windows with insulation or other upgrades, our guide on energy upgrade financing in Calgary explains the City's Clean Energy Improvement Program and what has closed.

Hail and windows

Calgary hail breaks glass, cracks vinyl frames and dents aluminum capping. When windows are replaced after a hailstorm, ask about sturdier frames, metal or fibre-cement trim instead of thin aluminum capping, and whether your insurer pays to replace like with like or toward an upgrade. Our hail-resistant exterior guide covers the options.

How long it takes

Most windows are made to order, so there is usually a wait of several weeks between ordering and installation, longer for custom shapes, dark colours and busy seasons after big hailstorms. Ask for the lead time in writing. Installation itself usually takes one to a few days for a whole house, longer for full-frame work on stucco.

Windows can be installed in winter, one or two at a time, so the house is never open for long, although sealants and exterior finishes prefer warmer days. Our guide to winter renovations explains what works in the cold.

What a good window quote includes

• The exact window product, frame material, glass package, colour and energy rating for each opening.
• Whether each window is an insert or full-frame installation.
• Removal and disposal of the old windows.
• Flashing, sill pans, air sealing and interior trim and caulking.
• Exterior capping or trim, and any stucco or siding repair around the openings.
• Permits if any openings change size.
• The manufacturer's warranty and the installer's workmanship warranty, separately.

Questions people ask

• Is it cheaper to replace all the windows at once? Usually, yes. One measure, one order and one crew visit cost less per window than doing a few at a time.
• Which windows should I replace first if I cannot do them all? The ones that leak, fog between the panes or have rotten frames, then the largest and coldest windows.
• Are black windows worth the extra cost? They are popular and look good on most houses, but they cost more and dark frames get hotter in strong sun. Our guide to exterior house colours for 2027 covers colour choices.
• Do new windows add value? They make a house more comfortable and appealing, but rarely return their full cost on their own when you sell.
