Percolation Tests FAQs, answered by experts

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

It is strongly advised not to touch or disturb asbestos-containing materials unless necessary. Asbestos fibers can be released into the air when the material is damaged or disturbed, posing serious health risks if inhaled. It is best to leave any handling of asbestos to trained professionals who can remove the asbestos safely.

According to the Environmental Protection Agency (EPA), you should contact the following officials to report a case of asbestos exposure:

  • Asbestos subject matter experts in your state 

  • EPA regional office

  • Toxic Substances Control Act (TSCA) Assistance Information Service Hotline via mail, email, or phone

  • EPA’s Asbestos Ombudsman via phone or fax 

Costs depend on property size, test types, and additional services like mold sampling.

Asbestos itself does not typically leak from a roof. However, if an asbestos-containing roof is damaged or deteriorated, it can release asbestos fibers into the air. This can occur when the roof is disturbed, such as during maintenance or repairs, or due to weathering over time. Exposure to airborne asbestos fibers can be harmful to health, so it is important to address any damaged asbestos roofs promptly and safely.
