Calgary's weather can change dramatically within a single day, which means rigid scheduling doesn't always work well for exterior window cleaning.
What Actually Matters for Cleaning
- Temperature: extreme cold causes cleaning solution to freeze on the glass before it can be wiped, which makes winter exterior cleaning impractical below a certain temperature.
- Wind: high wind makes squeegee work harder and less consistent, and is a real safety factor for any elevated or pole-reach work.
- Precipitation: cleaning right before rain or snow is pointless — the work gets undone within hours.
Why Flexibility Matters
A same-day check of conditions, and willingness to reschedule if a chinook or a snowstorm rolls in unexpectedly, matters more in Calgary than in cities with more predictable weather.
Best Windows for Exterior Work
Calm, dry days above freezing — which in Calgary means being genuinely flexible with scheduling rather than locking in a fixed day weeks in advance and hoping the weather cooperates.
What This Means for You
