Is asbestos commonly found in older homes?

Percolation Tests questions, answered by experts

When asbestos fibers become airborne, they enter a person's respiratory system. These fibers scar and damage the lungs and often lead to serious cancers like mesothelioma. Like many dangers in the house, asbestos isn’t easy to see when it could be causing serious damage. The amount of time exposed, combined with the person’s tolerance for asbestos inhalation and the amount inhaled, will all contribute to health problems.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

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.

Bathroom tiles can contain asbestos, just the same as patio tiles or kitchen tiles. Remember that asbestos was used primarily for its insulative and fire-resistant properties, both of which are desired in a house. Before we knew asbestos caused cancers and other diseases, it made a lot of sense to include it in many different building materials, including bathroom tiles.

Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.
