Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.
Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing.
The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.
Unfortunately, home inspections do not check for asbestos because of the liability factor involved. That’s why you should hire a trained professional with specialized equipment to test for it.
They will inspect all areas of the home and take samples of various materials to test. Opting for an asbestos inspection can prevent the risk of exposure to this hazardous material and save on costly repairs that may be required.
Whether or not to buy a home containing asbestos is ultimately a decision for the homebuyer, and there are several things to consider. When in good condition and contained, asbestos is unlikely to present a health risk—it’s when those tiny fibers are loose and airborne that they become a problem. Consider any renovations you plan on doing to the home that could disturb existing asbestos and the cost of removal. If an inspection finds asbestos in a home on the market, you could negotiate with the seller for a lower price, though this isn’t a sure thing.
Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.
