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.
If in doubt, treat the material as if it contains asbestos or have it sampled and analyzed by a qualified professional. A professional should take samples for analysis, since a professional knows what to look for, and because there may be an increased health risk if fibers are released.
Homes built before the 1980s could expose homeowners, their families and others to asbestos. It may hide in cement, floor tiles, insulation, walls and pipes.
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.
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.
It is difficult to tell when asbestos is in the air. The tiny fibers have no odor or taste, and they do not irritate your eyes or throat or make your skin itch. If you know or suspect there is asbestos in your home or workplace, leave the material alone.
Just having asbestos siding and roofing on your home does not pose a hazard to your health. Asbestos-containing roofing and siding in good condition are best left alone. Damaged roofing and siding should be carefully repaired. Sometimes asbestos-containing roofing and siding can be covered with new materials.
There is no way to know whether these materials contain asbestos without having them tested.
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.
Many nationwide department stores (like Home Depot) and online retailers (like Amazon) sell home test kits for asbestos (samples are sent to a lab for analysis). However, the EPA does not recommend testing asbestos yourself because it could expose you to its toxic airborne particles.
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.
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.
Inspect the surface pattern
Most asbestos materials will have a swirl or dimpled pattern on the surface. Newer materials that don't contain asbestos will have a smoother surface texture. You can't rely on this visual method alone; you should treat a patterned surface with caution.
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.
You can expect to pay an average of $500 to the air for asbestos. Subject to the number of samples you require and the size of your home, costs range around $200 to $800. This is comparable to the price of an inside air quality test, which sometimes includes asbestos in a list of wanted impurities.
How do I know if I have asbestos in my home (in floor tile, ceiling tile, shingles, siding, etc.)? The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory.
Symptoms of asbestosis
shortness of breath. persistent cough. wheezing. extreme tiredness (fatigue)
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.
Asbestos does not always need to be removed before a sale. If the material is in good condition and poses no immediate risk (e.g., it is contained and undisturbed), sellers can disclose its presence without taking further action.
-Compare the newer siding to older siding areas and look for evidence that indicates age. - Asbestos was particularly prevalent in siding that resembles shingles or was made to look like wood grain. - If your siding has these characteristics, then asbestos could be present.
Homes built before the 1980s likely have asbestos in them. For instance, if these homes have popcorn ceilings or vinyl flooring, they may contain asbestos. A simple rule is the newer a home is, the less likely it has asbestos materials. Homes built before the 1980s are likely to contain the mineral somewhere.
Sprayed coatings on ceilings, walls and beams/columns
This asbestos material will usually look white or grey in colour will usually have a rough surface and may also have been painted over. It was used for insulation on the underside of roofs and sometimes on the sides of buildings and warehouses.
As for how to test for asbestos yourself, only some states allow homeowners to perform a home asbestos test. Check with your state's environmental agency or health department first. If they allow it, you'll be able to purchase a kit with instructions on how to test for asbestos in the air.
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).
