Top 10 Best Percolation testing pros in Pasadena, CA

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: When did they stop using asbestos siding on houses?

• <div><p>In the 1980s, the use of asbestos in house siding materials underwent a significant decline, ultimately being phased out by the mid-1980s to early 1990s. This change was largely due to a growing awareness of the severe health risks associated with asbestos exposure, particularly its link to lung diseases and cancers. With increased public concern and regulatory agency involvement, building codes and regulations were updated to restrict the use of asbestos in construction materials. </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>

Q: How much does asbestos testing cost?

• <div><p>The cost for asbestos testing typically ranges from $400 to $800. The final price depends on several factors, including the number of samples needed, the size and age of the property, and the professional's expertise required for comprehensive testing. Larger or older properties may have higher costs.</p></div>

Q: What are the health risks if I’m exposed to asbestos tiles?

• <div><p>Damaged tiles can release asbestos fibers into the air. Anyone in the surrounding area who may inhale the fibers will have them settled in the lining of internal organs. Over time, it may lead to serious health conditions such as lung cancer and mesothelioma.</p><p>The only safe way to prevent these conditions is to avoid exposure to asbestos at all costs, even for a short period of time.</p></div>
