Window and Door Replacement in Calgary: Costs, Rebates, Quotes
The cost figures on this page are being verified against current local quotes and are not yet published as confirmed ranges. The hiring advice below is the part you can rely on.
Windows are Calgary’s big-ticket exterior trade, and the spread between quotes is the widest of any home service — triple-pane, code changes, and rebate paperwork all move the number by thousands. Comparing quotes only works if they describe the same window.
This page explains Calgary window pricing and the specs that actually matter.
Replacement windows in Calgary typically cost $800 to $1,500 per window installed, so a full house of ten runs $10,000 to $25,000. Entry doors run $1,500 to $4,000 and sliding patio doors $2,500 to $5,000.
What it costs
| Job | Typical range | Notes |
|---|---|---|
| Per window, installed | $800 – $1,500 | Triple-pane and larger sizes at the high end |
| Full house (10 windows) | $10,000 – $25,000 | Varies with size and style |
| Entry door replacement | $1,500 – $4,000 | Including frame and hardware |
| Sliding patio door | $2,500 – $5,000 | Triple-pane adds meaningfully |
How to choose a window installer
- Compare like for like: pane count, U-factor, and the frame material in writing.
- Ask whether the quote includes the interior trim and any stucco or siding repair around the opening.
- Ask about the ENERGY STAR rating and which rebate programme the windows qualify for.
- Ask for the installer’s own crew versus subcontractors — window performance is 50% install.
Red flags
- A "triple-pane is always better" pitch with no numbers — in Calgary it usually is, but the U-factor decides, not the word "triple".
- Quotes without per-window pricing.
- High-pressure financing pitches folded into the quote.
Common problems and what they cost
- Condensation or frost between panesroutine$800 – $1,500 per window
Seal failure — the window unit is done; the frame may be reusable.
- Drafts around old windowsroutine$100 – $500 for sealing vs replacement
Weatherstripping buys time; it is not a substitute for failed units.
- Sticking or hard-to-open windowsroutine$150 – $500
Often adjustment — but egress windows that will not open are a safety issue; fix promptly.
Frequently asked questions
Triple-pane or double-pane in Calgary?
For comfort and energy, triple-pane wins in Calgary’s winters and pays back over the window’s life; double-pane costs less up front. Get both prices and compare U-factors — then decide with real numbers.
Replace all windows at once or in stages?
Per-window pricing drops with volume, so doing a side or a floor at a time is the sensible middle path. Replacing one window at a time is the most expensive way to do the house.
