I have inherited my family's farmhouse in rural Missouri. We were told it was built in 1938. I was tearing up old linoleum flooring, to discover original wood floors. As I was working to also remove loose wallpaper, I found holes in the wall that revealed the old plaster and lathe walls. My concern is the possibility of asbestos. Was these walls made with any product that contained asbestos? Is there a spe******t in Missouri I should contact to take a look at my house?
