Mold Inspection and Testing
5,824 companies across 45 US metro areas list mold inspection and testing work. Here is what the job involves, what you can do yourself, and how to pick one.
What the Job Involves
A mold inspection is a visual and instrument check of a home for moisture and growth. Testing adds samples, usually air samples inside and outside for comparison, plus surface swabs or tape lifts, which go to a lab. The report tells you which mold types were found and how the indoor counts compare with the outdoor baseline.
Testing earns its cost in a few situations. You smell mold but cannot find it, you are buying or renting a home, someone is having health symptoms, or you want independent proof that a remediation job worked. When mold is already visible, most experts say to skip testing and deal with the moisture and the growth.
What You Can Do Yourself
Call a pro
Home test kits that grow spores in a dish almost always grow something, because mold spores are everywhere. They cannot tell you whether you have a problem. A moisture meter and a flashlight will tell you more for less money.
Questions to Ask Any Company
- Do you also do remediation? If so, who checks your work?
- How many air samples will you take, and will you take an outdoor control sample?
- Which lab analyzes the samples, and is it accredited?
- Will the report include moisture readings and photos, not only lab numbers?
- Are you licensed as a mold assessor where this home is?
