While asbestos can’t be directly absorbed through the skin—the fibers are too big—skin contact can still produce symptoms. Contact dermatitis can flare up in sensitive individuals but in most cases, the danger from asbestos comes from inhaling the fibers, or dust, that is produced when asbestos is disturbed. If you touch asbestos by accident, immediately wash yourself and your clothes.

Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.

Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.

It can be safe to live in a house with asbestos as long as the asbestos-containing materials are intact, in good condition, and not disturbed. Asbestos becomes dangerous only when its fibers are released into the air, which happens if the material is damaged, crumbling, or disturbed during renovation work. If you suspect asbestos is present, do not disturb it. Instead of removal, materials in good condition can sometimes be encapsulated. It is recommended to have regular professional inspections to monitor the condition of the asbestos and prevent health risks from potential exposure.

Yes. Gutting a house to the studs may actually be a good option if you believe a home contains toxic materials like asbestos, mold, or lead paint. However, this must be done under the supervision of licensed remediation experts.
