Where asbestos is found in homes
Asbestos was used in many building materials for insulation and as a fire retardant. In homes, the usual suspects are popcorn ceilings, vinyl floor tiles and their adhesive, pipe and boiler insulation, vermiculite attic insulation, cement siding and roofing, and joint compound. Most of it went into homes built before the 1980s.
Materials to know
- Popcorn ceilingsCeilings sprayed in the 1950s–1970s often did. Testing, risks and removal costs.
- Floor tiles9×9 tiles, sheet vinyl backing and black adhesive in older homes.
- Vermiculite insulationEPA says to assume it contains asbestos and leave it alone.
- Pipe and boiler insulationWhite pipe wrap and boiler insulation in older homes. Treat it as asbestos.
- Siding and roofingCement siding and shingles on older homes. Safe while intact; don't cut or break them.
- Joint compound and textured paintWalls finished before the 1977–78 ban. Test before you sand.
- Furnaces, stoves and ductsDuct tape, millboard, gaskets and heat shields on older heating equipment.
EPA's list
The EPA lists these places asbestos may be found in homes (EPA):
- Attic and wall insulation containing vermiculite
- Vinyl floor tiles, the backing on vinyl sheet flooring, and adhesives
- Roofing and siding shingles
- Textured paint and patching compounds on walls and ceilings
- Walls and floors around wood-burning stoves protected with asbestos paper, millboard or cement sheets
- Hot water and steam pipes coated with asbestos material or covered with an asbestos blanket or tape
- Oil and coal furnaces, and door gaskets with asbestos insulation
The Consumer Product Safety Commission adds soundproofing or decorative material sprayed on walls and ceilings (such as popcorn ceilings), furnace ducts wrapped in asbestos paper tape, and artificial ashes and embers sold for gas fireplaces (CPSC).
Which homes?
There's no single cut-off year. Official sources point to:
- "Until the 1970s, many types of building products and insulation materials used in homes contained asbestos" (CPSC).
- Popcorn ceilings installed from the 1950s to the 1970s (ATSDR).
- Buildings constructed by 1980: OSHA requires contractors to presume certain insulation and sprayed-on materials in these buildings contain asbestos, unless tested.
Some asbestos products stayed legal into the 1990s, so a newer home isn't a guarantee. See when they stopped using asbestos.
The rule that matters most
Undamaged asbestos that you leave alone is not likely to be a health risk (EPA). The danger comes when it's disturbed: sanded, sawed, drilled, scraped or torn out. Before any of that, get it tested.
