Asbestos in Boulder County

Asbestos is a mineral fiber commonly used in building construction materials for insulation and as a fire-retardant.

Asbestos and Health Risks

Asbestos is still used in building products because of its insulation and chemical, fire, and heat-resistant characteristics. It is reported to exist in over 3,000 different building products. Asbestos has never been totally banned in home building products and so is found in buildings of any age, including new construction.

Common Illnesses

Breathing asbestos dust causes lung diseases like lung cancer and asbestosis. Asbestos is not a health risk unless it is disturbed. Improperly removing asbestos building materials before major renovations will contaminate the living space of your home and expose you and your family to asbestos.

Common Asbestos-Containing Building Materials

In Colorado, common home-building materials contain asbestos, including:

  • Floor tile, linoleum, and related glue
  • Drywall and ceiling textures, including “popcorn” or “cottage cheese” textures
  • Drywall mud (also known as joint compound)
  • Pipe, duct, and boiler insulations
  • Vermiculite insulation
  • Cement asbestos board shingles and siding
  • Acoustic ceiling tile and plaster
  • Wall packing
  • Electrical wire insulation
  • And many others

Renovation, Demolition, Water, and Fire Damage

Never try to remove or dispose of asbestos-containing building material yourself. Safe removal of asbestos building material requires refined skills and is regulated by CDPHE. Only a state-certified asbestos abatement technician should work with asbestos. All asbestos building waste must go to an asbestos-qualified landfill approved by the Colorado Department of Public Health and Environment (CDPHE).
