Vancouver Exterior Painting: Dealing with Moisture & Rain Prep

Vancouver's beautiful but rainy climate presents unique challenges for exterior painting. Here's what makes painting in the Lower Mainland different from the rest of Canada.

The Moisture Factor

Vancouver averages 166 rainy days per year. That moisture affects exterior paint in several ways:
- Wood siding absorbs moisture — painting over damp wood traps water and causes peeling
- Mildew growth — Vancouver's humidity encourages mildew, which must be fully removed before painting
- Shorter cure windows — Paint needs dry time, and Vancouver's mornings often start damp

Our Vancouver-Specific Process

1. Moisture testing — We use a moisture meter to ensure wood is below 15% before painting
2. Mildew treatment — Full wash with mildew-killing solution, not just water
3. Extended dry time — We schedule around weather windows and allow extra cure time
4. Premium exterior paints — We use Benjamin Moore Aura Exterior, which is specifically formulated for high-moisture environments
5. Extra coats on exposed faces — North and west-facing walls get extra attention

Best Time to Paint in Vancouver

Late June through September offers the most reliable dry weather. July and August are prime months. However, we can work in spring and fall with careful weather monitoring.

Why It's Worth Doing Right

A properly prepped and painted Vancouver home exterior should last 8–12 years. Cut corners on moisture prep and you might see peeling within 2–3 years. The upfront investment in proper preparation pays for itself many times over.
