How Much Does a Mold Inspection Cost?

A mold inspection identifies whether you have a mold problem, how big it is, and — most importantly — what moisture source is feeding it. Here's what to expect.

What a mold inspection includes

• A visual inspection of affected and likely-affected areas
• Moisture readings and humidity checks to find the source
• Inspection of common hidden spots: behind walls, under floors, in attics and crawl spaces
• Sometimes air or surface sampling sent to a lab (this adds cost)

What affects the cost

Pricing varies with the size of the home, how many areas are involved, whether lab testing is included, and accessibility of spaces like crawl spaces. A basic visual inspection costs less than one with full lab sampling.

When you actually need an inspection

• You can see mold but don't know how far it spreads
• A persistent musty smell with no visible source
• After water damage or a flood
• Before buying or selling a home

If you already see significant mold, you may be better served going straight to remediation. See our guides on attic mold and crawl space mold.
