My husband and I are remodeling our house, and some one told us that the linolium might contain aspestos. I have done some research and found it was used in linolium 30 years ago, but our house is only 18 years old. How do I find out if the linolium used in my house contains it or not without having it sampled? Is there a year they stopped useing aspestos in linolium flooring? I appreciate all the responses I can get.
