DIY mold test kits

A DIY mold test kit gives you a first indication of whether a surface stain or musty smell is active mold, and sometimes what type. Surface (swab/tape) tests sample a visible spot; settling-plate and air tests sample what’s floating in the room; lab-analysis kits mail your sample in for a species report. They’re a useful screening step — but visible mold over about 10 square feet, or any mold from a known water leak, calls for a professional assessment that finds the moisture source. Use a kit to start the conversation, not to settle it.
