Mold spreads fastest in the conditions our region provides plenty of — humid summers, poorly ventilated bathrooms, and basements prone to moisture.
Early warning signs:
- A musty smell, even without visible mold — often the first sign, especially in basements and bathrooms
- Discoloration on walls, ceilings, or around window and door frames
- Warping or swelling on wood surfaces, including doors and trim, which absorb moisture more readily than people expect
- Increased allergy symptoms at home that improve when away from the house
Where to check first
Bathrooms, basements, around window frames, and anywhere water has previously leaked or flooded — even if it was addressed at the time, moisture can linger in materials longer than expected.
Prevention matters more than treatmentProper ventilation, promptly addressing any leaks, and using moisture-resistant materials in high-risk areas (like bathrooms) prevent the vast majority of mold issues before they start. This is also where materials matter — hollow-core doors in bathrooms are more prone to swelling and trapping moisture than solid-core options built to handle it.
