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.

No, but it’s common that they do. Gravity furnaces weren’t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn’t until later that we became aware of just how carcinogenic and dangerous asbestos could be.

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.

Most manufacturers stopped putting asbestos in linoleum before 1980 due to public concerns about its toxicity. However, the Environmental Protection Agency (EPA) didn’t ban asbestos-containing products until 1989, and a comprehensive ban was not announced until 2024. This means that homes built after 1989 may still have asbestos in their flooring.
