Before you hire — three checks
- Confirm the credential is current. Ask for the IICRC certification and confirm it at IICRC's locator.
- Get the scope in writing — containment, what's being removed, and post-work verification.
- For mold: keep assessment and remediation separate. An independent assessor writes the protocol; the remediator executes it. Even where not legally required, it protects you.
