Top 10 Best Percolation testing pros in Intercourse, PA

Q: Do all gravity furnaces have asbestos?

• <div><p>No, but it&rsquo;s common that they do. Gravity furnaces weren&rsquo;t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn&rsquo;t until later that we became aware of just how carcinogenic and dangerous asbestos could be.</p></div>

Q: What products still contain asbestos?

• <div><p>There are products that still contain asbestos, but they were typically installed decades ago. Common places where you may still find asbestos-containing materials are in siding, wrapped around ductwork, in older appliances (i.e., stove and gravity furnaces), and in floors. Asbestos was primarily used as an insulator, so anywhere in an older home where you lose heat is where you will most likely find asbestos.</p></div>

Q: Should I have my home tested for asbestos?

• <div><p>Many homeowners may never have to test their homes for asbestos. Asbestos particles are only dangerous if they become airborne. If you plan to do construction or notice damage to piping, siding, or drywall, you should hire a specialist to test for asbestos. </p><p>If you plan to remodel your home or have any concerns, you should have your home tested for asbestos just to be safe. </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: What magnification do you need to see asbestos fibers?

• <div><p>If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.</p></div>
