Why a seller cares

A mold test usually follows a moisture finding on the general inspection, and its results can frighten a buyer out of proportion. Knowing where your home's moisture is before listing is how sellers avoid a surprise here.

A simple example

The inspector finds staining under the kitchen sink. The buyer orders a mold test, which comes back with elevated levels in that cabinet only.

Mold test: a simple example
What the test findsWhat tends to follow
Elevated levels in one small areaRemediation of that area, a few hundred dollars, usually by the seller
Elevated levels in the air across the basementProfessional remediation, and often a nervous buyer
Normal levelsNothing; the item closes

A mold test measures a moisture problem. Fixing the moisture is the real work.
