What Is Asbestos Clearance Testing?

Interior of a house under construction with exposed wooden wall studs, wiring, and insulation.

Asbestos clearance testing is performed following asbestos abatement activities to verify that regulated work areas have been properly cleaned and are ready for reoccupancy. The process typically includes a visual inspection and air sampling performed in accordance with applicable project requirements.

What to Expect During Our Visit

A makeshift indoor tent structure made of clear plastic sheeting held up by adjustable metal poles, set up inside a room with wooden flooring and partially visible wall and window.

We will review the project scope, inspect the regulated work area, and evaluate the cleanliness of the containment prior to air sampling. If conditions are acceptable, air samples will be collected and submitted to an accredited laboratory for analysis.

What Happens After Clearance Testing?

Kitchen under renovation showing exposed wall studs, plumbing, electrical outlets, and a window with wooden blinds.

Following laboratory analysis, results are compiled into a clearance report documenting the visual inspection, air sampling performed, and laboratory findings. Results can then be used to support project closeout and reoccupancy decisions.

When Is Clearance Testing Performed?

Asbestos clearance testing is typically performed after asbestos abatement activities have been completed and the containment has undergone final cleaning. Clearance testing may be required by project specifications, regulatory agencies, property owners, or other stakeholders.
