Asbestos Removal: What Homeowners Need to Know

Asbestos was used extensively in building materials through the late 1970s. If your home was built before 1980, there’s a reasonable chance it contains asbestos in insulation, floor tiles, roofing, or pipe wrap. Here’s what you need to know before disturbing any of it.

When Is Removal Required?

Asbestos that’s in good condition and left undisturbed is generally not an immediate health risk. The danger comes when materials are damaged, deteriorating, or about to be disturbed by renovation or demolition. In those cases, the EPA requires that asbestos-containing materials be properly handled by trained professionals before work proceeds.

Some situations that typically trigger removal include major renovations that affect walls, ceilings, or flooring; demolition of any structure containing asbestos; and visibly damaged or crumbling asbestos materials.

Removal vs. Encapsulation

Full removal (abatement) means physically taking out the asbestos-containing material and disposing of it at an approved facility. Encapsulation involves sealing the material in place with a specialized coating so fibers can’t become airborne.

Encapsulation is often cheaper and less disruptive, but it’s only appropriate when the material is in stable condition and won’t be disturbed in the future. If you’re doing a renovation that involves tearing into walls or ripping up flooring, removal is usually the only option.

EPA Regulations and NESHAP

The EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP) govern how asbestos must be handled during renovation and demolition. Most states also have their own licensing requirements for asbestos abatement contractors. Federal law requires that any commercial or public building demolition include an asbestos inspection first, and many local jurisdictions extend similar rules to residential projects.

Hiring a Certified Contractor

Never attempt to remove asbestos yourself. Improper handling can release microscopic fibers that cause serious lung disease, including mesothelioma. When hiring a contractor, verify they hold current state and federal asbestos abatement licenses, carry proper liability insurance, and will provide air monitoring during and after the project.

Get a written scope of work, including containment procedures, disposal plans, and post-abatement clearance testing. A professional should always test materials before assuming they contain asbestos — visual identification alone is unreliable.

Find certified asbestos removal contractors in your area to schedule an inspection.
