How to choose a mold inspector in Port Huron

The U.S. EPA says that in most cases, if you can see mold, you do not need a test to know it is there. A test helps when you smell mold but cannot find it, or after remediation.

A good inspection looks for the water source with a moisture meter and, where useful, a thermal camera. Air samples alone do not show where the mold grows.

Indoor air samples mean little without an outdoor sample taken at the same time. Ask for both, and for the lab report itself.

Michigan has no state licence for mold inspectors. Ask what training and certification the inspector holds and which accredited lab reads the samples.

A home inspection for a sale is not a mold inspection. Ask the inspector what the inspection covers.
