Even some homes built during the 1980's may still contain some asbestos in floor tiles, ceilings, pipe cement, and other products and materials. This is because the EPA didn't extend the asbestos ban to include all newly manufactured products until 1989.
Asbestos was commonly used in thousands of products and home construction materials before the 1980s. From the 1930s to the 1970s, building materials, vinyl goods and other products contained asbestos. Regulations in the 1970s and 1980s limited asbestos use in new products.
In California, like many other parts of the world, homes built before 1980 are likely to contain asbestos in various forms. Understanding its presence, risks, and necessary actions is crucial for homeowners, renters, and anyone involved in renovation or maintenance of older properties.
When was asbestos used in homes? Because of its fire resistant and insulating properties, asbestos was commonly used between 1900 and 1980. Many homes built before the 1980s still contain asbestos ceiling tiles, insulation, piping, and flooring that must be professionally encapsulated or removed for health reasons.
In 1981, the list of building materials that are likely to contain asbestos is shorter than it was in the 1970's but we regularly find asbestos-containing materials in 1980's buildings. The only way to know is to take samples of the materials that were disturbed, and take them to a qualified, experience laboratory.
The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory. EPA only recommends testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material.
Asbestos is no longer added to popcorn ceilings because it's a known health risk. The chances of your ceiling containing asbestos are low for any installations in the late 1980s or after. Newly constructed ceilings don't use asbestos.
Your older home probably did not come with an inventory of all asbestos containing materials, but if the house in which you live was built before 1980, there's a good chance that you'll find asbestos containing materials in the walls, ceiling, roof or floors – or all of the above.
There is no way to know whether these materials contain asbestos without having them tested.
If you think there may be asbestos in your home, don't panic. Asbestos-containing materials that aren't damaged or disturbed are not likely to pose a health risk. Usually the best thing is to leave asbestos-containing material alone if it is in good condition.
Most old asbestos ceiling tiles look light colored, slightly textured and powdery white. They often have small dotted indentations. If your tiles remain intact there is little to no health risk. However, deteriorating ceilings can put all of your building's users at risk.
If you suspect that asbestos is present in cement, it's best to contact a professional. A specialist can confirm that asbestos is present and let you know the next steps to take. A cement analysis uses a water-absorption test to determine if asbestos is present in the cement.
Asbestos use has declined since the 1970s, but many older homes still contain asbestos. In an older home, asbestos may be in the paint, insulation and floor tiles. Many U.S. homes and public buildings built before the 1980s, such as schools and office buildings, contain asbestos.
In 1977, the Consumer Products Safety Commission banned asbestos in joint compounds and drywall tape. However, these products may still have been used until 1980 or later from the oversupply that had been purchased prior to the ban. As a result, buildings constructed before 1990 may still contain asbestos in drywall.
The only reliable way to know if your home contains asbestos is to hire an environmental consulting firm or asbestos building inspector to take samples and have them tested in a lab.
Most popcorn ceilings were made with asbestos before the dangers of this deadly material were widely known. Between the 1950s and 1980s, asbestos was commonly used in construction materials for its fire-resistant properties.
Houses built between 1930 and 1950 may have asbestos as insulation. Asbestos may be present in textured paint and patching compounds used on wall and ceiling joints. Their use was banned in 1977. Artificial ashes and embers sold for use in gas-fired fireplaces may contain asbestos.
One of the most worrying issues with asbestos is that in the event that it does get disturbed, it can be easily released into the air, and remain there for some time. It is thought that disturbed asbestos can stay airborne for as long as 48 to 72 hours before settling.
What does asbestos cement roofing look like? The roof panels are normally a cloudy grey colour and look like a blend of different materials. They are most commonly corrugated (wavy) sheeting like the attached picture.
In the majority of homes, yes. Popcorn ceilings are easy to notice, and make homes look and feel dated. Removing them is a quick fix, but it's recommended to leave the work to a pro to ensure there's no asbestos contamination in the home.
One-time exposure to asbestos can cause diseases, including mesothelioma cancer. Researchers have found repeated exposure to asbestos increases the risk of developing asbestos-related cancers. The risk to individuals who have a one-time exposure to asbestos is generally lower compared to long-term or repeated exposure.
Generally, those who develop asbestos-related diseases show no signs of illness for a long time after exposure. It can take from 10 to 40 years or more for symptoms of an asbestos-related condition to appear (2).
To accurately determine whether your ceiling has asbestos requires a professional lab test; however, visual cues may help suggest the possibility that materials contain it.
