Do I need an asbestos test?
You need a test before you disturb a material that might contain asbestos, or if it's damaged. If building materials aren't damaged and won't be disturbed, the EPA says you don't need to test them.
When you don't need a test
"If building materials in your home aren't damaged and won't be disturbed, you do not need to have your home tested for asbestos" (EPA). Asbestos that's intact and left alone "is not likely to pose a health risk."
When to test
| Situation | Test? |
|---|---|
| Renovating, remodeling or demolishing in an older home | Yes, before work starts. Sanding, drilling, cutting and tearing out are what release fibers. |
| Material is damaged, crumbling or water-damaged | Yes, or have a professional assess it. EPA says more than slightly damaged material needs repair or removal by a professional. |
| Replacing a furnace, boiler or flooring | Yes, for the insulation, tape, tiles or adhesive involved. |
| Buying an older house | Worth considering as part of the inspection. See buying a house with asbestos. |
| Vermiculite attic insulation | No: EPA says to assume it contains asbestos instead. See vermiculite. |
| Intact, and you're not touching it | No. |
If you're not sure
Treat the material as if it contains asbestos and leave it alone. That's EPA's advice: "If in doubt, treat the material as if it contains asbestos and leave it alone." Try the checker for what official sources say about your material.
