If your home feels damp even though the heat is on, you’re not imagining it. Vancouver’s wet climate means moisture is almost always in the air, and it doesn’t go away in the winter. When that moisture gets trapped indoors, it can make your home feel clammy and uncomfortable, even when it is warm.
Understanding where the moisture is coming from is the first step toward improving comfort and indoor air quality.
What Is Causing Excess Moisture in Your Home?
Sealed Homes Trap Moisture
Modern homes are built to be energy efficient. While this helps retain heat, it also traps moisture produced indoors through everyday activities such as breathing, cooking, and bathing.
Rising Warm Air Pulls Moisture Inside
Warm air naturally rises and escapes through the upper levels of a home. As it exits, it creates negative pressure that pulls in cooler, moisture-laden air from basements, crawl spaces, and small foundation gaps.
Cold Surfaces Cause Condensation
When warm indoor air comes into contact with cold surfaces like windows or exterior walls, it can reach its dew point. This causes condensation to form, which increases moisture levels and can contribute to mold growth over time.
Everyday Living Adds Humidity
A typical family of four can generate up to 50 litres of water vapour each week from routine activities such as showering, laundry, and cooking.
Professional Solutions to Control Indoor Humidity
Maintaining indoor humidity between 30 and 50 percent requires more than simply turning up the heat. The right setup and solutions can make a significant difference.
Heat Recovery Ventilators and Air Exchangers
HRVs and ERVs are essential in Vancouver’s climate. These systems continuously replace stale, moisture-laden indoor air with fresh outdoor air while retaining heat, helping balance humidity levels without sacrificing energy efficiency.
Smart Thermostats with Humidity Control
Modern smart thermostats can monitor indoor humidity and adjust system operation accordingly. Some models can automatically run the fan or ventilation system to reduce moisture while maintaining comfort.
Improved Airflow
Keep furniture slightly away from exterior walls to allow air circulation and prevent moisture from becoming trapped.
Weather Sealing
Inspect caulking and weatherstripping around windows and doors. Proper sealing helps prevent humid outdoor air from leaking into your home.
