If you hire a dedicated asbestos inspector near you in addition to your local home inspector, it will cost between $200 and $800.

In general, home inspectors do not do physical testing, but will provide a visual assessment so you know what you are working with.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.
