Common hiding spots in older buildings
Asbestos can hide in many parts of older buildings, especially those built before the late 1970s and into the 1980s. Because it was valued for fireproofing and insulation, it turns up in a wide range of materials.
Common places include popcorn or textured ceilings, vinyl floor tiles and the glue beneath them, insulation around pipes and boilers, wall and attic insulation, and joint compound used on drywall. It can also appear in roofing, siding, some old wallboard, and around old heaters and ducts.
The age of the building is the biggest clue. Homes built before 1980 are more likely to contain asbestos materials, though it can appear in later construction too. You usually cannot tell whether a material contains asbestos just by looking — only lab testing can confirm it.
The key point is not to disturb, sand, scrape, or drill into suspect materials in an older unit. If you are worried about asbestos in your rental, a free, confidential review can help you understand your rights and next steps.
