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.

Although the use of asbestos has declined since the 1980s, it remains in several different types of building construction materials for insulation and as a fire retardant. Typically, asbestos can be found in materials such as ceiling and floor tiles, heat-resistant fabrics and coatings, and roof shingles. You may also find asbestos in textured paint and patching compounds.

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.

Since DIY asbestos removal isn’t the best option to save money, there are other steps that you can take to help cut costs when dealing with this project. After speaking with your asbestos removal expert, discuss if encapsulation is an option. If it is, you can save between 15% to 25% on overall project costs over demolition and disposal. In addition, when speaking with your professional, discuss if there are any tax credits available for your removal project. Finally, check with your homeowner’s insurance to see if any removal costs might be covered. However, be aware that this is usually only applicable if the asbestos is due to a covered incident, like a tree falling into your roof.
