Q: Is asbestos still used in siding?

• <div><p>Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.</p></div>

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 factors affect testing costs?

• <div><p>Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.</p></div>

Q: What pollutants are commonly tested for?

• <div><p>Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.</p></div>

I am very pleased with how professional and courteous Cade is. When he was done he told me to let him know if he missed something or I had an issue with something. There were just a few things I thought could have been done more to my liking and he was here the next day and put my issues right....
