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. Any flooring made between 1950 and 1989 more than likely contains asbestos. <a href="https://www.angi.com/articles/how-to-tell-if-you-have-asbestos-floor-tile.htm">Asbestos tiles</a> can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.</p></div>

Do I need to be worried about asbestos?

• <div><p>If your home was built before 1989 and still has original vinyl, there’s a high probability of asbestos mixed into the old flooring, which can harm you and your family if it’s disturbed from removal. If you suspect that you have asbestos, you’ll want to call in <a href="https://www.angi.com/nearme/asbestos-abatement/">an asbestos removal expert</a> to evaluate the situation. </p></div>

What year did they stop putting asbestos in linoleum?

• <div><p>Most manufacturers stopped putting asbestos in linoleum before 1980 due to public concerns about its toxicity. However, the Environmental Protection Agency (EPA) didn’t ban asbestos-containing products until 1989, and a comprehensive ban was not announced until 2024. This means that homes built after 1989 may still have asbestos in their flooring.</p></div>

Done in one day, at a reasonable cost. A test of efficiency is performed afterward by a separate company, and the tester said they did a quality job. We are very, very happy with the result.

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.
