To test for mold in a house, start by looking for visible signs like black spots or a musty smell, especially in damp areas like basements or bathrooms. You can buy a DIY mold test kit at a hardware store; it usually involves taking a sample with a swab or tape and sending it to a lab for analysis. For a more thorough check, hire a professional inspector who uses moisture meters and air sampling to detect hidden mold behind walls or under floors.
