Vermiculite testing before renovations is highly recommended, both for the safety of your family and the workers. If you plan to renovate an area containing vermiculite, it is your duty as a responsible homeowner to inform the contractor of its presence so they can take the necessary precautions.
Many homeowners choose not to perform a vermiculite test beforehand because, after vermiculite removal work, asbestos air testing is conducted to ensure the extraction was done correctly. This test verifies the compliance of the vermiculite removal work, ensuring that no asbestos fibers have been released into the air. Therefore, it is possible to avoid paying twice for the same type of test, as the cost of the test conducted after the extraction is similar to that of a test that would be done before the work to check for asbestos in the vermiculite.
