What it is
Asbestos was incorporated into numerous building products over many decades. Depending on the age, manufacturer, and application, materials such as plaster systems, joint compounds, textured finishes, adhesives, insulation products, flooring materials, and roofing products may require evaluation before disturbance. Many property owners associate asbestos only with insulation, but asbestos was historically used in a wide variety of building materials.
Where it's found
Across nearly every interior and exterior building system in pre-1990 construction: floors, walls, ceilings, roofs, mechanical rooms, attics, and exterior cladding. Historic homes throughout Massachusetts often contain materials that should be evaluated before renovation or demolition.
When and why
Asbestos was used heavily from the 1920s through the late 1970s and continued in some products into the 1990s. Material age alone does not confirm or rule out asbestos.
How it's tested
Bulk samples are collected with wet methods and PPE, then analyzed by PLM (EPA 600/R-93/116) with point counting where indicated. Testing is driven by the specific materials to be disturbed rather than assumptions about age.
