Asbestos testing before renovation: scope first, samples second.

Schedule before demolition or material disturbance

Asbestos fibers can be released when asbestos-containing materials are cut, sanded, scraped, broken or otherwise disturbed. Testing should occur early enough for the results to affect estimating, scheduling and the construction plan.

Give the inspector the real construction scope

A vague request to “test the bathroom” is not enough. Will the project remove only floor tile, or also underlayment, wall plaster, joint compound, ceiling texture, pipe insulation and window components? Provide plans, proposals and photos when available.

New surfaces can conceal older materials

Buildings are layered. New flooring may cover older tile and mastic. Drywall may cover plaster. A replacement ceiling may conceal earlier texture or tile. Building age alone does not resolve what is present in the work area.

Use the report to plan the next step

The report should identify the inspected scope, samples, locations, analytical results and relevant limitations. If asbestos is identified, an appropriately licensed abatement professional can evaluate removal or other control options. RPB does not perform abatement.
