Homes built in the 21st century don’t contain asbestos, a cancerous mineral that causes mesothelioma.

Unfortunately, millions of homes from asbestos’ heyday still exist throughout the United States. Unsuspecting families still spend hours of their days inside these carcinogenic hotbeds.

According to the U.S. Census Bureau 2019 American Community Survey, approximately 12% of homes were built prior to 1940. More than half the houses were built before 1980, which is the unofficial demarcation line separating asbestos’ peak usage and phasing out.

That means more than half of U.S. homes were built with asbestos in or around the walls, floorboards, ceiling tiles, roof tiles, insulation, pipes and electrical wires. If they weren’t refurbished within the last 30 years, then the degraded “legacy” asbestos poses a risk to all inhabitants.

Most purchases are for older homes, increasing the chances of buying a hazardous residence. The National Association of Home Builders conducted a survey in 2018 of preference versus actual purchase. Around 30% wanted a brand new home, but only 11% of home sales were for new construction. The other 89% were for existing homes.

Before purchasing an existing home, we recommend getting a thorough inspection to detect any asbestos. If any exists, ask for an asbestos remediation expert to make your new residence safe.
