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: 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>

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>
