The short answer

How Asbestos Affects Your Health

When asbestos-containing materials are damaged, they release tiny fibers into the air. You can inhale these fibers without noticing. Once inside your lungs, they can cause scarring and inflammation over many years. The most serious risks include mesothelioma, a rare cancer of the lining of the lungs or abdomen, and lung cancer. Asbestosis is a chronic lung disease that makes breathing difficult.

The health effects usually appear 10 to 40 years after exposure. The amount and duration of exposure matter. Even brief, high-level exposure can be harmful, but long-term exposure raises the risk more. If you feel unwell or have concerns about past exposure, see a doctor. They can evaluate your symptoms and guide you on next steps.

Where Asbestos Hides in Older Homes

Asbestos was widely used in building materials before the 1980s. In homes, it can be found in insulation, floor tiles, ceiling tiles, drywall joint compound, and textured paint. It also appears in cement pipes, roofing shingles, and some adhesives. Water damage can crack or saturate these materials, causing asbestos fibers to become airborne.

If your home was built before 1980 and has water damage, you should assume asbestos may be present. Do not disturb damaged areas. Avoid sweeping or vacuuming debris that might contain asbestos. Instead, keep the area damp and limit access until a professional can evaluate it. The pros can test materials and recommend safe removal if needed.

  • Insulation and pipe wrap
  • Vinyl floor tiles and backing
  • Textured ceilings and walls
  • Roofing and siding materials
  • Drywall and joint compounds
  • Cement pipes and flues

What to Do If You Suspect Asbestos

First, do not touch or disturb the material. If it is intact and not damaged, it may pose little risk. But if water damage has crumbled or cracked it, you need to act carefully. Turn off any fans or air conditioning that could spread fibers. Keep people and pets away from the area.

Contact a local water damage pro who can assess the situation and coordinate with an asbestos abatement specialist if needed. The pros will follow safety protocols to contain the hazard. They can also address the underlying water issue, such as a leak or flooding, to prevent further damage. For help with water damage cleanup, consider the related services listed below.

How Water Damage Increases Risk

Water damage can cause asbestos-containing materials to deteriorate. For example, a ceiling with asbestos in the joint compound may crack and release fibers when it gets wet. Flooding can soak wallboard and insulation, making them fragile. Drying out these materials can also cause them to crumble.

In a hot semi-arid climate, rapid drying might make materials brittle. If you live in Fresno, you know how quickly things dry out. That drying process can turn asbestos materials into dust. So, if you have water damage in an older home, treat all damaged materials as potentially hazardous until proven otherwise.

The Role of Professional Abatement

Asbestos removal is not a do-it-yourself job. The pros use specialized equipment, personal protective gear, and proper containment to prevent fibers from spreading. They also dispose of asbestos waste according to regulations. Attempting to remove asbestos yourself can put you and your family at risk.

When you hire a water damage pro, they can coordinate with an asbestos abatement specialist. The pros will handle the water damage repair, while the abatement specialist removes the hazardous material. Always ask for a plan before work begins. If you have doubts, seek a second opinion. Your safety comes first.

Frequently asked questions

How long after exposure do symptoms appear?

Symptoms of asbestos-related diseases often take 10 to 40 years to develop. That long delay makes it easy to forget past exposure. If you experience persistent cough, shortness of breath, or chest pain, see a doctor. Early detection can help manage the condition.

Can I remove asbestos myself?

No. Removing asbestos yourself is dangerous and often illegal. Disturbing it releases fibers into the air. Professional abatement is the safe way to handle it. The pros have the right equipment and training to contain and dispose of asbestos properly.

Is all asbestos harmful?

Not all asbestos is equally dangerous. When materials are intact and not disturbed, they pose little risk. The danger comes when fibers become airborne. Damaged or deteriorating asbestos is the main concern. If you have intact asbestos, monitor it and avoid disturbing it.
