What clearance air monitoring actually confirms
Clearance air monitoring is the final step in any friable asbestos abatement project. It's not a formality — it's the scientific confirmation that the abatement was successful and the space is safe to re-occupy. Three things it confirms:
PCM analysis confirms that airborne fiber counts are below 0.01 f/cc — the Michigan clearance standard.
Clearance samples inside the work area confirm that the negative-pressure containment kept fibers from migrating to the rest of the home.
The clearance certificate becomes part of your permanent project record — useful for insurance, real estate disclosure, and regulatory compliance.
Clearance air monitoring is included in our abatement project quotes for all friable projects. For standalone clearance monitoring on projects performed by another contractor, pricing is $300–$600 depending on project size and number of samples required.
