Keep Your Siding in Top Shape: Home Exterior Tips for Bothell-Lynnwood, WA Homeowners

In the Bothell-Lynnwood area, your home’s siding faces frequent rainfall, damp air, moss growth, and seasonal storms. From cool, wet winters to mild but rainy springs and falls, siding in neighborhoods like Canyon Park, Alderwood Manor, and North Creek requires regular care to stay durable and visually appealing.

At CertaPro Painters® of Bothell-Lynnwood, WA, we understand how the Pacific Northwest climate impacts your home. Below are our top tips for protecting your siding and maintaining your home’s curb appeal throughout the year.

Inspect Your Siding Regularly

We recommend inspecting your siding every 3–6 months—especially after long stretches of rain or winter storms. In areas like Martha Lake, Mill Creek, and Thrashers Corner, constant moisture can lead to mildew, moss growth, wood rot, or warped panels.

Keep an eye out for green or black staining, bubbling paint, cracked caulking, and loose or shifting boards. Focus on shaded areas, near gutters, and around landscaping where moisture tends to accumulate.

Clean Your Siding Annually

Due to the high moisture levels and tree coverage common in Western Washington, mold, algae, and debris build up quickly on siding—particularly in forested or shaded areas like Brier and Bothell West. Annual cleaning helps prevent long-term damage and keeps your exterior looking fresh.

Use a hose or low-pressure washer with a soft brush and a mild detergent to scrub off dirt and mildew. Avoid strong pressure, which can damage older siding or push moisture into the walls.

Repair Damage Promptly

Even small cracks or gaps can lead to serious problems in our damp climate. Moisture intrusion and wood rot are common in this region if siding damage is left unaddressed—especially during the rainy season.

While minor caulking or painting may be done on your own, larger repairs are best handled by professionals. At CertaPro Painters® of Bothell-Lynnwood, WA, we offer siding repair and exterior painting services that stand up to the region’s persistent moisture and mild temperatures.
