What Happens If Asbestos Gets Disturbed During Repair?

When asbestos-containing materials are cut, sanded, or broken, they release dust filled with tiny, sharp fibers. These fibers are too small to see and can stay suspended in the air for hours. Anyone breathing that air can inhale the fibers deep into their lungs, where the body cannot easily remove them. This immediate contamination turns your indoor air into a health risk.

If you suspect asbestos has been disturbed, stop work immediately. Have everyone leave the area and avoid spreading the dust. Do not sweep or vacuum, as this will stir up more fibers. Close off the room by sealing the door with plastic sheeting and tape to prevent contamination from spreading to other parts of your home. Your next step is critical for safety. You must contact a qualified asbestos professional.

• Leave the area immediately and keep others out.
• Do not turn on fans or the HVAC system, which can circulate fibers.
• Avoid disturbing the material further in any way.
• Do not attempt to clean up the dust yourself.
• Contact a qualified asbestos abatement professional for assessment.
• Consider consulting your doctor if you believe you were exposed.

The safest approach is to assume older building materials contain asbestos. In homes built before 1980, materials like textured ceilings, vinyl floor tiles, pipe insulation, and some siding may contain it. Before starting any demolition, repair, or renovation, have a sample tested by an environmental laboratory. If asbestos is present, budget for proper abatement before the repair work begins to ensure a safe outcome.

• Identify the age of your home and suspect materials.
• Assume popcorn ceilings or old floor tiles may contain asbestos.
• Have a qualified inspector take samples for testing.
• Never sand, drill, or cut into suspected materials.
• Plan for asbestos abatement costs in your repair budget.
• Ensure all contractors check for asbestos before starting work.
