Can You Handle It 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 Before You Hire
- 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?
