How do you identify asbestos tiles?

• <div><p>If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used.

Q: What years was asbestos used in floor tiles?

• <div><p>Asbestos was most commonly produced and integrated into building products from the 1920s to the late 1980s. In reality, asbestos use should have ceased much sooner because asbestos was linked to cancer in studies produced as early as the 1950s. You can even extend that number past the 1980s due to stockpiled materials and because some countries treat asbestos use differently. It may also be found more in commercial applications than residential.</p></div>

Q: Can you gut a house down to the studs if you think it has asbestos?

• <div><p>Yes. Gutting a house to the studs may actually be a good option if you believe a home contains toxic materials like asbestos, mold, or lead paint. However, <b>this must be done under the supervision of licensed remediation experts.</b> </p></div>

Q: Can you cover asbestos tile with carpet?

• <div><p>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.</p></div>

Q: Does an N95 mask protect against asbestos?

• <div><p>No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, <a href="https://www.angi.com/articles/hire-pro-asbestos-testing-and-removal.htm">hire an asbestos abatement professional</a> immediately and avoid the area until they arrive for the inspection.</p></div>
