Percolation Tests questions, answered by experts

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.

Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.

Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.

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.

The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.
