Asbestos Removal questions, answered by experts

if you install new siding on top of old asbestos siding, you may keep the fibers trapped, but it would not necessarily be considered encapsulation. To do so properly requires a professional, who uses a certain type of sealant that needs to be spread over the asbestos in a number of layers in order to trap all the fibers. Although you may be able to buy this sealant yourself, it is highly advised that, once you find asbestos, you call a pro immediately. 

Asbestos siding on its own doesn’t present a health risk. Asbestos fibers only become airborne when you disturb the material. As long as the siding is in good condition, it shouldn’t release dangerous fibers into the air. If you’re ready to replace the siding anyway or if it’s in poor condition, hire a local asbestos removal contractor to remove, repair, or cover it safely.

Epoxying over asbestos tiles is generally considered a safe option when done correctly. Epoxy acts as a sealant, encapsulating the asbestos tiles and preventing the release of asbestos fibers into the air. The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.

Asbestos-containing materials, like duct wrap, should be encapsulated using a sealant specifically formulated for asbestos. These sealants work to bind with asbestos fibers and help further neutralize them as a health risk. Whenever you’re working near asbestos-containing materials, be sure to keep safety as a top priority and wear a P-100-rated respirator as well as protective clothing.

In the 1980s, the use of asbestos in house siding materials underwent a significant decline, ultimately being phased out by the mid-1980s to early 1990s. This change was largely due to a growing awareness of the severe health risks associated with asbestos exposure, particularly its link to lung diseases and cancers. With increased public concern and regulatory agency involvement, building codes and regulations were updated to restrict the use of asbestos in construction materials.
