we are having some work done in our house and one wall in our living room has had some patching up on it however it had blown. We are getting the full wall re done however to help out plaster we have done down to the brick. It never crossed my mind about asbestos however I've been informed it could of been in the plaster from our walls. Is that the case? How can I tell? I'm so worried now because the dust was shocking. I think our house was built in 1920 and part of the wall seemed original. Thank you there is nothing I can do because it's done now but I'm really worried.
