How Often Should You Clean Your Windows in Calgary?

Short answer: most Calgary homes need a professional clean twice a year — spring and fall. Here's why, and when you should break that rule.

Why Calgary Is Harder on Windows Than Most Cities

Chinook winds kick up dust and grit constantly. Winter leaves behind salt spray, sand from de-icing, and hard water spots from melting snow. Add in pollen season and the odd summer dust storm, and your windows are working overtime just sitting there.

Most cities can get away with once a year. Calgary can't.

The Twice-a-Year Rule

• Spring (April–May): Clears winter's buildup — salt, sand, hard water spots, and grime baked on by months of freeze-thaw.
• Fall (September–October): Gets you a clean slate before winter hits, and clears summer's dust and pollen before it sets in over the cold months.

When You Need More Than Twice a Year

A few situations push past the standard schedule:

• You live near a busy road, construction site, or open field — dust accumulates faster.
• You have large ground-floor or picture windows that show every mark.
• You're selling your home and want it photo-ready.
• You just finished a renovation (see our post-construction cleaning guide for that one specifically).

Signs You've Waited Too Long

Hard water spots that don't wipe off with a cloth, visible haze even on a clear day, and window tracks so gritty they stick — all signs you're past due, not just due.
