Question 1

What is asbestos?

Accepted Answer

Asbestos is a naturally occurring mineral composed of thin, needle-like fibers. Historically, it has been used in a variety of building materials and products due to its resistance to heat, fire, and chemicals and its insulating properties. However, asbestos is now known to be a serious health hazard. When materials containing asbestos are disturbed, tiny fibers can become airborne and, if inhaled, can lead to serious health issues such as lung cancer, mesothelioma, and asbestosis.

Question 2

How many asbestos samples are required when testing for asbestos in homes or commercial buildings?

Accepted Answer

The number of asbestos samples required for accurate testing depends on the size and complexity of the area being assessed. For residential properties, we generally recommend collecting at least 3-5 samples from each area of concern, such as insulation, flooring, or roofing materials. For commercial buildings, which often have larger and more varied spaces, a more extensive sampling may be necessary. Our licensed and insured professionals, who are well-versed with regulations in the state of Colorado, will conduct a thorough inspection and determine the exact number of samples needed to ensure a comprehensive analysis. This personalized approach ensures the safety and compliance of your property.

The "3-5-7 rule" for asbestos sampling dictates the minimum number of bulk samples to be collected from surfacing materials based on the size of the homogeneous area: 3 samples for areas less than 1,000 square feet, 5 samples for areas between 1,000 and 5, 000 square feet, and 7 samples for areas greater than 5,000 square feet. While the 3-5-7 rule specifically applies to surfacing materials, other material types like thermal system insulation or miscellaneous materials (e.g., flooring, caulking) have different, though often similar, sampling requirements. For example, at least 3 samples are typically required for each homogeneous area of thermal system insulation, with some exceptions for small patched sections. While the 3-5-7 rule is a common guideline, the EPA's "Pink Book" recommends 9 samples per homogeneous area for surfacing materials regardless of the area's size

Question 3

When should I have my property tested for asbestos?

Accepted Answer

You should have your home or business tested before any renovation, demolition, or remodeling, especially if it was built before the late 1980s. Even small projects like removing popcorn ceilings or replacing flooring can disturb asbestos.

Question 4

How long does asbestos testing take, and when do I get results?

Accepted Answer

The inspection itself usually takes 1–2 hours, depending on the size of the property. Lab results typically come back within 24–72 hours, with rush options available.

Question 5

Who should perform the testing, and are they certified?

Accepted Answer

Testing must be done by a trained professional from an accredited laboratory or an inspector certified under local/state regulations (e.g., OSHA, EPA, CDPHE in Colorado). Certified testers follow strict chain-of-custody and handling procedures to ensure both accuracy and safety.
