Joint Compound and Plaster Asbestos

[Patrick Slagle]

Hey all,

How common is it for asbestos to be in plaster walls or joint compound of an old residential home? I have a duplex in Richmond Virginia that's around 100 years old, and will require some demoing and repairs of walls. The house has been rehabbed throughout the years, so the materials used could be anywhere within the last 100 years.

Any idea how likely we may have walls with asbestos? 

Thanks!
