From drizzles to downpours, the Pacific Northwest’s moisture-rich climate can challenge even the sturdiest home exteriors. Protecting your siding means staying proactive — not reactive. Whether your siding is wood, fiber cement, or vinyl, consistent care keeps it in top shape.
1. Inspect Your Siding Every Season
Make it a habit to walk around your home at least twice a year. Look for cracks, peeling paint, or gaps where caulk has failed. Catching these issues early helps prevent water intrusion and decay beneath the surface.
2. Keep It Clean
Moss, algae, and mildew love damp conditions. Power wash gently once or twice a year to remove buildup. Avoid harsh chemicals that can damage paint or siding — opt for mild detergents and soft brushes.
3. Repaint or Reseal as Needed
A weather-resistant paint acts as a shield against moisture and UV damage. Most homes in the Northwest benefit from a new coat every 7–10 years, depending on exposure. For wood siding, consider stain or sealant maintenance every 3–5 years.
4. Manage Drainage and Landscaping
Ensure gutters are clean and downspouts direct water away from your foundation. Trim shrubs and trees that block sunlight or trap moisture against siding — airflow helps surfaces dry faster after rain.
5. Caulk and Seal Seams Annually
Even tiny gaps allow moisture to creep in. Reapply exterior-grade caulk around windows, doors, and joints before the wet season begins.
6. Choose Durable, Climate-Appropriate Materials
If you’re planning a siding replacement, consider fiber cement or engineered wood — both handle humidity better than untreated wood. Pair with high-quality paint for long-lasting protection.
Pro Tip:
In regions with frequent rain, prioritize breathable paint coatings. They allow moisture to escape from within the walls while keeping water out, reducing the risk of blistering and rot.
Blog Summary:
Northwest weather can be harsh, but with proper maintenance — from sealing seams to repainting regularly — your siding will remain strong, clean, and beautiful for decades.
