We have just bought a 41 year old house and we are worried about aspestos. Could you please tell me what it looks like.... We have alot of white powdery stuff in the bathroom,on the foors and walls and in the exhaust fan,the bathroom has been renovated. We also found some hay or straw looking material in the plaster on the walls in the toilet..I won't stop stressing until I get some answers. Tanks.
