Q: Does knob and tube wiring have asbestos?

• <div><p>Knob and tube wiring is an older type of electrical wiring that's no longer used and <a href="https://www.angi.com/articles/knob-and-tube-electrical-wiring-safe.htm">generally not considered safe</a>. 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.</p></div>

Q: Can I conduct asbestos testing myself, or should I hire a professional?

• <div><p>Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.</p></div>

Q: How long do asbestos fibers stay in the air?

• <div><p>Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.</p></div>

Q: How can I save money on asbestos removal?

• <div><p>Since DIY asbestos removal isn&rsquo;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 <b>15% to 25%</b> 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&rsquo;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. </p></div>
