Tom Silva replies: The advice you received is correct: The best way to deal with old asbestos floor tiles is to cover them up. That’s enough to prevent the damage and wear that can release fibers into the air; no sealer is needed. Carpeting and a suitable pad will do the trick. In a basement I’d suggest a rubber-based carpet pad rather than a fiber pad. You could also cover the tiles with new vinyl flooring, linoleum, or even ceramic tiles. However, as a favor to future owners of your house, make some note of the fact that asbestos tiles are under the new flooring. That way, no one will be endangered years from now when they start to rip up the new flooring and find asbestos tiles beneath.
Other Helpful Advice:
Although some areas allow homeowners to remove asbestos flooring on their own, it’s not something that is advised. Before making any decisions, check your city and state regulations regarding asbestos abatement.
