Fast checklist (most musty smells are fixed in a day)
- Ventilate briefly: open two windows for a cross‑breeze (10–15 minutes if weather allows).
- Run fans: bathroom fan during/after showers; kitchen fan while cooking.
- Dry wet items: hang towels fully open; dry shoes; don’t pile damp laundry.
- Increase airflow: leave bathroom door open after showers; use AC/fan if available.
- Check for leaks: look under sinks and around toilets—if you see water stains or active dripping, message your host.
Visitor guidance only—follow building/host instructions if provided.
Common “hidden” causes (what visitors miss)
- Towels drying bunched up (never fully dry)
- Shower steam with the bathroom door closed and no fan
- Wet shoes left on a mat overnight
- Cooking steam without a fan or window cracked
When to contact your host (so it doesn’t escalate)
- Visible water stains that are growing
- Active leak (sink/toilet/tub)
- Persistent odor after a day of ventilation + drying
Send a message with photos and where you noticed it—this speeds up help.

FAQ
Why does my Montreal apartment smell musty?
Most often it’s humidity from showers/cooking plus damp towels/shoes that aren’t drying fully. Ventilation, fans, and better drying habits usually fix it quickly.
How can I reduce humidity fast?
Create a brief cross-breeze, run bathroom/kitchen fans, dry towels fully open, and avoid piling damp laundry.
When should I contact my host?
If you see active leaks/water stains, or the odor persists after a day of ventilation and drying, message your host with photos.
