An asbestos inspection aims to identify, quantify, and report asbestos containing material (ACM) in a home or building, especially before renovation or disturbance. The inspection requires sampling of suspect ACM within the home. Usually samples the size of a quarter will be extracted and sent to an accredited laboratory for analysis. Our base asbestos inspection includes 3 samples, however, the sample quantity tends to increase depending on the quantity of the suspect material and its category.

Asbestos categories and sampling quantities are set forth by the Colorado Department of Public Health and Environment Regulation 8.

Asbestos containing material is placed into one of three categories:

Surfacing Material: ACM that is spray or trowel applied for decorative, acoustical, or fireproofing purposes. A few examples include various wall textures like popcorn ceiling, orange peel, skim coat, plaster, and knockdown.

Thermal Systems Insulation (TSI): ACM that is used to inhibit heat transfer or prevent condensation on pipes, tanks, boilers, HVAC systems, ducts, and hot and cold water systems. Common examples include pipe insulation, boiler insulation, and HVAC duct wrap.
Miscellaneous Material: ACM that is not surfacing material or TSI! A few examples include floor tile, mastic adhesive, transite pipes and siding, joint compound, roofing felt and shingles, vermiculite insulation, carpet padding, window glazing, and caulking.

Our inspector will place the suspect ACM into one of these three categories then determine the sampling procedure. Sampling practice set forth by the state requires the following:

This means that sampling will usually begin at 2-3 samples per homogeneous area (material uniform in color and texture) and increase with square footage or volume.
