The Hidden Dangers of Asbestos

Asbestos is a naturally occurring mineral that was heavily used in construction due to its strength, heat resistance, and insulating properties. Before regulations changed in the 1980s, it was commonly found in materials like insulation, floor and ceiling tiles, roofing products, and other building components—often hidden from plain sight.

• Insulation (especially around pipes and boilers)
• Floor tiles and the adhesive beneath them
• Ceiling textures (like “popcorn ceilings”)
• Roofing and siding materials
• HVAC duct insulation
• Older window glazing or caulking

While modern building codes have largely phased out asbestos use, many older Brooklyn buildings still contain these materials — especially in neighborhoods like Cobble Hill, Carroll Gardens, and Fort Greene, where pre-war architecture is abundant.

Here’s the thing: asbestos isn’t hazardous just because it’s present—it becomes dangerous when it’s disturbed. When materials with asbestos are cut, broken, or mishandled, they can release tiny fibers into the air—so small you won’t see them or even know they’re there. But once you breathe them in, those fibers can settle deep in your lungs and quietly cause serious health problems over the years.

Breathing in these fibers over time can lead to serious long-term health problems, including:

• Asbestosis – A chronic lung condition caused by asbestos fibers, leading to scarring and long-term breathing difficulties.
• Lung Cancer – Risk significantly increases with asbestos exposure, particularly among smokers.
• Mesothelioma – A rare, aggressive cancer that develops in the lining of the lungs or abdomen, almost always linked to asbestos exposure.

These health issues often don’t show up until decades after exposure, which is why many people don’t realize the harm until it’s far too late. That’s exactly why early awareness and taking preventative steps are so important—it’s the best way to protect yourself before the damage is done.

Many homes built prior to 1980 likely contain asbestos in building materials, so it’s important to have a certified inspection done before beginning any repairs or remodeling. That means:

• Homeowners renovating older kitchens or bathrooms
• Landlords preparing units for new tenants
• Contractors doing demolition or remodeling work
• Families living in homes with deteriorating materials

Even small DIY jobs — like removing old flooring or patching a ceiling — can release harmful fibers if proper precautions aren’t taken.

You can’t tell if a material contains asbestos just by looking at it. The only way to know for sure is through professional testing by a licensed inspector.

If you suspect your property may contain asbestos, especially during a renovation or cleanup project, do not disturb the material. Rather than taking chances, it’s best to consult a certified asbestos inspection service for peace of mind. They can safely test your property, identify any hazards, and guide you through the proper next steps based on your specific situation.

We always recommend getting a professional assessment before starting any major cleaning or renovation job — especially in older Brooklyn properties.

Here are our top tips for protecting yourself and your family from asbestos exposure:

• Treat unknown materials as potentially asbestos-containing — especially in homes built before the 1980s.
• Avoid disturbing anything you suspect may contain asbestos — avoid sanding, scraping, or drilling until inspected.
• Hire a licensed asbestos inspector if you plan to renovate.
• Work with certified professionals for any removal or abatement.
• Keep materials intact and undisturbed if removal isn't necessary.

Brooklyn is filled with beautiful, historic buildings — many of which were constructed during the peak of asbestos use. Whether you live in a charming brownstone, a converted warehouse, or an older apartment building, understanding the risks is essential.
