Mold Inspection & Testing
Air samples, lab reports, and panic before the remediation bill
Bottom line
Strong cash-flow candidate with manageable operations.
Mold inspection and testing businesses inspect properties, collect air or surface samples, coordinate lab analysis, and produce reports for homeowners, landlords, buyers, property managers, and insurers. It sits upstream of remediation: customers often need independent testing before deciding whether a full cleanup is justified.

How It Works
Inspectors visit properties, document moisture issues, use meters and cameras, collect air or swab samples, send samples to accredited labs, and deliver findings to clients. Revenue comes from inspection fees, sample markups, real-estate transaction work, landlord disputes, insurance claims, and add-on indoor-air-quality testing.
