Your seasonal guide to protecting — and improving — your home in the Pacific Northwest.

Living in Washington comes with breathtaking scenery: lush forests, sparkling lakes, majestic mountains… and yes, lots of rain. While the PNW climate helps keep our landscape green, it also creates unique challenges for homeowners. Moisture, fluctuating temperatures, and heavy seasonal rainfall make regular home maintenance absolutely essential — especially if you want to preserve your home’s value, prevent costly repairs, and prepare for future resale.

Whether you're a longtime resident, a first-time buyer, or a seller getting ready for the market, here are 7 must-know tips for maintaining and protecting your Washington home.

1️⃣ Prioritize Roof & Gutter Maintenance — Your First Line of Defense Against Rain

In Washington, the roof handles everything: constant moisture, moss growth, falling leaves, heavy rainstorms, and seasonal wind. Neglecting roof care can lead to leaks, mold, damaged insulation, and expensive repairs.

What Homeowners Should Do:

• Clean gutters 2–3 times a year, especially in fall and spring.
  
  
• Check downspouts to ensure they’re carrying water at least 3–6 feet away from the foundation.
  
  
• Look for shingle lift, moss, granule loss, or dark patches — signs aging shingles need attention.
  
  
• Consider installing gutter guards if your home is near pine trees or heavy foliage.
  
  
• Hire a professional annual roof inspection to catch issues early.
  
  

Why It Matters in Washington:

Clogged gutters cause water to overflow and seep into siding, crawl spaces, and foundations — one of the most common causes of water damage in Western Washington homes.

2️⃣ Inspect Crawl Spaces & Sump Pumps — Small Spaces, Big Protection

Crawl spaces are often “out of sight, out of mind,” but in the PNW, they’re critical. Damp soil, rain runoff, and poor ventilation can quickly turn a crawl space into a moisture trap.

Check These Key Areas:

• Standing water or damp soil
  
  
• Insulation sagging or falling down
  
  
• Vapor barrier tears
  
  
• Signs of rodents or pests
  
  
• Mold or mildew odors
  
  

If you have a sump pump:

Maintenance Tips:

• Test it twice a year, especially before rainy season.
  
  
• Clean the pump and pit to keep debris from clogging.
  
  
• Consider a battery backup system for winter storms.
  
  

Why It Matters in Washington:

Heavy rainfall + slow drainage = ideal conditions for crawl-space flooding and mold. Keeping this area dry protects your home’s structure, air quality, and long-term value.

3️⃣ Moisture Control & Mold Prevention — The PNW’s Most Common Challenge

Mold grows fast in damp climates — and Washington’s moisture levels make it a year-round concern. Without intentional moisture control, homes can suffer from poor air quality, wood rot, and costly damage.

Top Moisture-Control Strategies:

• Use dehumidifiers in basements and lower-level rooms.
  
  
• Run bathroom fans for 20–30 minutes after showers.
  
  
• Install proper ventilation in laundry rooms and kitchens.
  
  
• Open windows regularly to circulate fresh air during dry days.
  
  
• Check windowsills and walls for condensation — a sign humidity is too high.
  
  

If You See Mold:

• Clean small patches with vinegar or specialized cleaners.
  
  
• Call a professional for anything over 10 square feet or recurring growth.
  
  

Why It Matters in Washington:

Even well-maintained homes can struggle with moisture — it’s simply part of PNW living. Staying proactive prevents small issues from becoming expensive repairs.

4️⃣ Winterize Your Pipes — Avoid Freeze Damage in Cold Snaps

While Washington doesn’t experience extreme winters everywhere, cold snaps do happen — and frozen pipes can burst, causing catastrophic water damage.

Winterizing Tips:

• Disconnect garden hoses & shut off exterior spigots.
  
  
• Wrap exposed or uninsulated pipes with heat tape or foam insulation.
  
  
• Keep interior temps above 55°F, even when away.
  
  
• Open sink cabinets on freezing nights to help warm air circulate.
  
  

Why It Matters in Washington:

Eastern Washington, the foothills, and higher elevation areas are especially at risk. Even Western Washington gets surprise freezes — and repairs from burst pipes can cost thousands.

5️⃣ Landscaping for Wet Soil — Protecting Your Yard and Your Home

Washington’s frequent rainfall makes proper landscaping and drainage essential. Poor yard grading and saturated soil can push moisture toward your foundation or overwhelm perimeter drains.

Landscaping Strategies:

• Ensure soil slopes away from the home.
  
  
• Add gravel beds or French drains to improve water flow.
  
  
• Keep plants and shrubs trimmed back to promote airflow.
  
  
• Avoid planting trees too close to the home — roots can damage foundations or drainage systems.
  
  
• Use PNW-friendly plants that love water but don’t encourage root rot.
  
  

Why It Matters in Washington:

Good yard drainage prevents foundation cracks, crawl-space issues, and standing water — all common in neighborhoods with compacted or clay-rich soil.

6️⃣ Exterior Paint & Siding Care — Protect Your Home’s Shell

Moisture, moss, and UV exposure all take a toll on Washington homes. Keeping your exterior sealed and protected prevents rot, warping, and premature aging.

Maintenance Tips:

• Pressure wash siding gently once a year to remove buildup.
  
  
• Inspect caulking around windows & doors annually.
  
  
• Repaint every 5–10 years, depending on material & exposure.
  
  
• Look for signs of rot or soft wood, especially near trim and decks.
  
  
• Vinyl siding? Check for warping or loose panels after storms.
  
  

Why It Matters in Washington:

Moisture trapped behind siding is one of the top causes of structural damage in the PNW. A well-maintained exterior preserves both curb appeal and home value.
