Testing for mold in a house is easier than you think. Start by looking for visible growth in damp spots like basements, bathrooms, and under sinks. A musty smell is a big clue. For hidden mold, use a DIY test kit from a hardware store: take samples from air or surfaces, following the instructions to mail them in for analysis. Or, hire a professional for a thorough check if you suspect a big problem.
