Why Rainy Season Triggers Mold Growth in Medford, OR
Medford’s rainy season (November through April) brings welcome moisture—but also creates the perfect breeding ground for mold and mildew. When humidity stays above 60% indoors, spores settle on cool surfaces like basement walls, bathroom grout, and window sills. Left unchecked, they can trigger allergies, damage drywall, and even rot wood framing.
1. Control Indoor Humidity Levels
Aim for 30–50% humidity. Use a hygrometer to monitor moisture.
Run exhaust fans. Turn on bathroom and kitchen vents during and after showers or cooking.
Dehumidify. Place portable dehumidifiers in damp areas (basements, laundry rooms) to pull excess moisture from the air.
2. Improve Ventilation & Airflow
Open windows briefly. Even in winter, 5–10 minutes of cross‑ventilation helps exchange humid indoor air.
Use ceiling fans. A gentle breeze discourages spores from settling.
Keep furniture off walls. Air can circulate behind couches and dressers—common hidden mold spots.
3. Address Leaks & Water Intrusion Immediately
Inspect roof, gutters, and downspouts before the first major storm. Clean and repair to prevent overflow.
Seal foundation cracks with masonry caulk to stop groundwater seepage.
Fix plumbing drips under sinks, behind toilets, and around washing machines as soon as you spot them.
4. Regular Cleaning for Mildew Removal Medford, OR
Bathroom maintenance:
Wipe down tile grout and shower curtains after each use.
Apply a vinegar or tea‑tree oil spray weekly to deter mildew.
Laundry care:
Run a monthly hot‑water cycle with baking soda to clean your washer tub.
Don’t leave wet towels or clothes in the laundry room—hang them to dry immediately.
Basement & crawl spaces:
Sweep and mop concrete floors monthly with a mild bleach solution (1 cup bleach to 1 gallon water).
Store cardboard boxes off the floor on pallets; replace cardboard with plastic bins.
5. Use Mold‑Resistant Materials & Treatments
Mold‑resistant paint: Repaint high‑moisture rooms (bathrooms, laundry) with a mildew‑inhibiting formula.
Silicone caulk: Replace old, cracked caulk around tubs and sinks with mold‑resistant silicone.
Moisture barriers: Install vapor barriers in crawl spaces to block ground moisture.
