The Seattle Home Maintenance Calendar: Nine Months of Water Management

2026-06-11 ยท Seattle Home Maintenance Editorial

Fall: The Main Event

Gutters cleaned twice (before and after leaf-drop), downspouts tested and extended, roof and moss assessment, crawlspace vent check, and exterior caulking before the rains settle in. October readiness defines the year.

Winter: Watch the Envelope

After windstorms: roof scan, fence lines, and tree limbs. Watch for condensation on windows (ventilation, not weather), musty closets on exterior walls, and crawlspace standing water. Run bath fans longer; moisture inside is the season's real adversary.

Spring: Moss and Probe Season

Treat roof moss (gently โ€” pressure washing shortens shingle life), probe decks and trim for rot, service the heat pump or furnace, and reseed the lawn the rains will water for you.

Summer: The Dry Sprint

Paint, roof work, deck refinishing, and any excavation โ€” everything exterior happens July-September. Book in spring; the whole region shares twelve dry weeks.
