Asbestos for Homeowners

If your home was built before the 1980s, it may contain asbestos in the flooring, ceilings, siding, insulation or around the furnace. Asbestos that’s in good shape and left alone is usually not a danger. The risk comes when you sand, scrape, cut, drill, tear out or demolish it during a remodel. Here’s how to find out what you have and handle it safely and legally.

Where asbestos hides in homes

WhereWhat to look for
Floors9-inch by 9-inch vinyl tiles, other older vinyl tile and sheet flooring, and the black adhesive (mastic) under them
Ceilings and wallsPopcorn or textured “cottage cheese” ceilings, some textured paints and plaster, older drywall joint compound
Attic and wallsVermiculite insulation (pebbly, gray-brown or gold, like small pieces of mica)
Heating systemsWhite or gray wrap on pipes and ducts, boiler and furnace insulation, duct tape-like joint wrap, furnace door gaskets
OutsideCement siding shingles, roofing shingles and felt, window glazing putty and caulk
Other spotsOld fireplace and wood stove parts, older appliances, electrical wire insulation, some old patching compounds

You can’t tell by looking. Many of these products were also made without asbestos. Testing is the only way to know.

Should I leave it alone?

Often, yes. Asbestos material that’s intact, not damaged, and won’t be disturbed is usually safest left in place. Check on it from time to time.

Getting it tested

Warning: Don’t disturb vermiculite insulation. Much of it came from a mine contaminated with asbestos. Don’t store things in an attic with vermiculite, keep children out, and hire a professional if it must be disturbed.

Can I remove it myself?

It depends on your state, the material and the amount.

Look up your state in Asbestos Rules by State and confirm with the agency before you start.

Our advice: hire a pro for most jobs

Even where it’s legal, DIY asbestos removal is risky. Fibers you can’t see can spread through your house and stay in carpets and ductwork for years, exposing your family. Professionals have the containment, negative air machines, respirators, training and disposal arrangements to do it right. Hire a licensed contractor for:

If you do any work yourself

Only where your state allows it, and only for small amounts of non-friable material such as a few floor tiles or siding shingles:

Disposal

Asbestos waste must go to a landfill or facility approved to accept it, not your curbside trash. Call your local landfill or solid waste agency first. Most require the waste to be wetted, double-bagged or wrapped in heavy plastic, sealed and labeled. Some require proof of testing or an appointment.
