Percolation Tests FAQs, answered by experts

There are products that still contain asbestos, but they were typically installed decades ago. Common places where you may still find asbestos-containing materials are in siding, wrapped around ductwork, in older appliances (i.e., stove and gravity furnaces), and in floors. Asbestos was primarily used as an insulator, so anywhere in an older home where you lose heat is where you will most likely find asbestos.

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.

While it's possible to cover asbestos tile with carpet, it's not recommended. Encapsulating tile beneath carpet doesn't eliminate the health risks. Over time, the asbestos tiles could degrade, releasing fibers into the air and potentially contaminating the carpet. Disturbance during carpet installation or removal might also release fibers.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

It can be safe to live in a house with asbestos as long as the asbestos-containing materials are intact, in good condition, and not disturbed. Asbestos becomes dangerous only when its fibers are released into the air, which happens if the material is damaged, crumbling, or disturbed during renovation work. If you suspect asbestos is present, do not disturb it. Instead of removal, materials in good condition can sometimes be encapsulated. It is recommended to have regular professional inspections to monitor the condition of the asbestos and prevent health risks from potential exposure.
