How often should I check my crawl space?

A look at least once in fall and once in spring is a sensible habit in a wet climate. Check again after heavy storms or plumbing work. Look for standing water, damp or sagging insulation, a torn vapor barrier, and musty smells. Wear protective gear and avoid entering tight spaces unsafely.

Do bathroom fans really make a difference?

Yes. Showers add a lot of water to the air, and a working fan carries it outside instead of leaving it on walls and ceilings. Make sure the fan vents outdoors, not into the attic, and run it during the shower and for a while afterward.

When does a damp spot need a professional?

If the spot keeps coming back, grows, smells musty, or sits on soft or warped material, it is worth a professional look. The same goes for any leak you cannot find. A small, dry, surface stain that cleans up and stays gone is usually something you can monitor.

Prevention calendar

A seasonal mold prevention calendar for Seattle homes

Want to keep mold from ever becoming a project? A little routine goes a long way. Long wet seasons, steady rain, mild temperatures, moss and damp make mold easy to start in the Seattle area. This calendar spreads simple checks across the year. Small habits protect your home, its condition and its resale value.

What should I do in fall, before the rain settles in?

Fall is prep season. The goal is to get water moving away from the house before the wet months arrive.

Clean gutters and check that downspouts carry water well away from the foundation.
Look at the roof for moss, lifted shingles and damage from late-season wind.
Check that the soil around the house slopes away from the walls.
Open the crawl space and look for standing water, damp insulation or a torn vapor barrier.
Make sure crawl space vents and dryer vents are clear and not blocked by leaves or plants.
Test bathroom and kitchen fans to confirm they run and actually move air.

It is also a good time to clear stored boxes away from exterior walls and basement corners so air can move.

What should I watch for in winter?

Winter is when moisture builds indoors. Cooking, showers and drying laundry all add water to the air, and cold windows give it a place to condense.

Run fans during and after showers and cooking.
Wipe condensation from windows and sills so it does not soak into frames.
Keep furniture a little away from cold exterior walls.
Watch for musty smells in closets, bathrooms and lower floors.
After a windstorm, check the attic and ceilings for new stains that could mean a roof leak.
Look under sinks and around water heaters for slow drips.

A simple humidity meter can help you notice when indoor air stays damp. Ask a provider what range suits your home.

What spring tasks help the most?

Spring is inspection season. You can see what the wet months did.

Walk the exterior and look for stained siding, soft trim or peeling paint.
Remove moss from the roof and shaded areas using methods suited to your roofing, or ask a roofer.
Re-check the crawl space for moisture, new stains and signs of pests or damaged insulation.
Look in the attic for damp insulation, dark patches on the underside of the roof deck, or poor ventilation.
Check caulk around windows, tubs and showers, and replace it where it has cracked.

Older craftsman houses may have gaps and settled framing that let in water. Newer townhomes often have tight envelopes, so ventilation matters even more.

What about summer?

Summer is repair season, and the dry weather is your friend.

Fix any leaks, drainage problems and roof issues found earlier in the year.
Improve grading, extend downspouts, or add drainage where water has pooled.
Replace worn bath fans or add ventilation where air feels stuffy.
Clean and service the dryer vent.
Trim shrubs and trees back from the walls so siding can dry out.

If a larger repair is needed, doing it now means the home is ready before the next rainy season.

What habits help all year?

Act on a leak fast, even a small one.
Dry anything that gets wet, such as carpet, drywall and furniture, as soon as you can.
Keep air moving with fans and open doors.
Keep a short log of what you checked, fixed and when. It helps at resale.

When is it time to get help?

Some signs are bigger than routine upkeep: a musty smell that will not go away, stains that return after cleaning, soft or warped materials, or visible growth that covers more than a small patch. Standing water in a crawl space or a roof leak also calls for a professional look. Early action usually means a smaller job.

If you want help, describe what you see in a request and independent providers in the Seattle area can respond, depending on availability.
