Prevent Indoor Mould: Humidity & Moisture Checks for BC Homes
Taskio Services July 03, 2026
Living in Metro Vancouver means loving lush rainforest surroundings, but winter brings months of relentless humidity. Without proper ventilation, moisture collects on window frames and cold exterior drywall corners, leading to black mold growth.
5 Essential Humidity Control Rules
- Maintain relative indoor humidity between 35% and 50% using a digital hygrometer.
- Run bathroom exhaust fans for at least 20 minutes AFTER taking showers.
- Pull couches and beds 2 to 3 inches away from exterior drywall to allow warm air flow.
- Run a compressor dehumidifier during heavy rain weeks.
- Inspect exterior window caulking and replace cracked sealant.
