Why mold shows up in Maryland

Maryland gets around 45 inches of rain a year with warm, humid summers, and much of its housing is older with basements that hold moisture. Humid air, plumbing leaks, and flooding from coastal storms or heavy rain all feed mold growth. The fix always starts with controlling the moisture, and for anything serious a licensed local pro is the right call.

Mold questions in Maryland

Is mold a common problem in Maryland?+

Yes. Humid summers, a long damp season, and a lot of older housing mean mold is a routine home and building concern rather than a rare event.

Does flooding cause mold in Maryland?+

It can. Coastal storms, tidal flooding, and heavy summer rain leave standing water and soaked materials that grow mold within a day or two if they are not dried out quickly.

When should I call a professional?+

For anything larger than about 10 square feet, mold behind walls or in HVAC, or growth tied to sewage or flooding, bring in a licensed local pro.
