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.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.

The signs of asbestos exposure are often subtle and may not appear for many years, or even decades, after initial contact. This long latency period is one of the primary dangers associated with asbestos.

When symptoms do manifest, they can include:

• Shortness of breath

• A persistent, dry cough

• Chest pain or tightness

• Fatigue

• Wheezing

• Weight loss

• Difficulty swallowing

• A dry, crackling sound from the lungs when breathing

These symptoms are non-specific and can be mistaken for other respiratory conditions, making diagnosis challenging. Prolonged exposure can lead to serious diseases as the asbestos fibers cause scarring and inflammation in the lungs. These conditions include asbestosis, lung cancer, and mesothelioma.

Due to the vague nature of early symptoms, regular medical check-ups are crucial for anyone with a known history of asbestos exposure, particularly in an occupational setting. If you suspect asbestos is present in your home, a professional inspection is recommended.
