    How to compare providers

    Ask whether the inspection is independent from any remediation work that may follow.

    Confirm what you receive: written findings, photos, moisture readings, lab results, or clearance documentation.

    Ask how the inspector decides whether cleanup, repair, or follow-up testing is needed.
