Can I Sample Asbestos Myself?

Is It Legal?

The answer depends on who is collecting the sample, the type of property, and the state where the property is located. In many states:

• Homeowners may collect samples from their own owner-occupied residence for laboratory testing.
• Contractors generally may not collect asbestos samples unless they hold the required state accreditation or license.
• Commercial, industrial, institutional, and government facilities often require inspections to be performed by accredited asbestos building inspectors in accordance with applicable federal and state regulations.

Why Hiring an Accredited Inspector Is Usually the Better Option

Although collecting a sample yourself may appear to save money, there are several advantages to hiring an accredited asbestos inspector. A professional inspector can:

• Identify all suspect asbestos-containing materials — not just the obvious ones.
• Determine homogeneous material areas.
• Collect representative samples in accordance with industry standards.
• Minimize disturbance of suspect materials during sampling.
• Coordinate laboratory analysis through an accredited laboratory.
• Prepare a written inspection report suitable for renovation, demolition, insurance, or regulatory purposes when applicable.

Many homeowners are surprised to learn that asbestos may be present in more than just insulation. Flooring, mastics, drywall joint compound, ceiling textures, roofing materials, siding, caulks, glazing compounds, and other building materials may also contain asbestos.

Common Mistakes with DIY Sampling

Improper sampling can lead to:

• Damaging additional building materials.
• Collecting a sample that is not representative of the material.
• Failing to identify all suspect materials.
• Creating unnecessary dust.
• Delaying renovation or demolition projects because additional sampling is required.

In many cases, homeowners only sample one material while overlooking several others that may also require testing.

When You Should Hire a Professional

Professional asbestos inspections are strongly recommended when:

• You are planning a renovation.
• You are planning a demolition.
• The property is commercial or industrial.
• The building is a school or public facility.
• The material is damaged or deteriorated.
• Multiple suspect materials are present.
• An insurance company requests documentation.
• A contractor requires an asbestos survey before beginning work.

An accredited inspector can provide a comprehensive evaluation that may help prevent project delays, change orders, and unexpected discoveries after construction has begun.

What Happens After the Sample Is Collected?

Whether collected by a homeowner (where permitted) or by an accredited inspector, the sample should be analyzed by a laboratory accredited for asbestos bulk material analysis.

The laboratory will determine whether asbestos is present and report the asbestos type or types, if detected, along with the percentage of asbestos contained within the material. Those results can then be used to help determine the appropriate next steps for renovation, demolition, maintenance, or abatement.
