Clearance testing in California

Clearance is the test after removal, not the test before it. It confirms the work area before you rebuild.

When people ask

  • Asbestos abatement is finished and the area needs clearance
  • Lead abatement or interim controls need a clearance sample
  • A contractor will not close walls until there is a report

The credential

Asbestos clearance and lead clearance are not interchangeable. The partner must hold the credential that matches the material: Cal/OSHA for asbestos, CDPH for lead.

Say which material was removed when you request a tester. This page covers asbestos and lead clearance only. For mold, see Mold testing.

Request a tester

Tell us the test and the city. You get a job reference, and the service credit is part of that referral.
