Asbestos in Plaster Walls

Older home renovation has started getting harder to follow with all the asbestos identification, testing requirements, and removal regulations flying around. As someone who has worked on historic homes, I spent real time learning the ins and outs of identifying and handling asbestos in plaster. Today, I will share it all with you.

When Asbestos Was Used

Probably should have led in this part, truthfully—asbestos was commonly added to plaster from the 1940s through the 1970s.

Identification

• Cannot identify by appearance alone
• Professional testing required
• Assume asbestos present in pre-1980 homes until tested

Safety Concerns

• Intact plaster generally safe
• Disturbance releases dangerous fibers
• Cutting, sanding, or demolition creates hazards
• Professional removal recommended

What to Do

• Test before any renovation work
• If positive, hire licensed abatement contractor
• Never disturb suspected asbestos materials
• Check local regulations for requirements
