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 do professionals test for other toxic materials in a home?

• <div><p>Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.</p></div>

Q: What are the common signs that asbestos is present in a property?

• <div><p>Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.</p></div>

Q: What does water do to asbestos?

• <div><p>Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.</p></div>

Q: How long does it take to see test results?

• <div><p>A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won&rsquo;t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. </p></div>
