If flooring is your only concern,depending on your plans for new flooring, often times you can go over the existing,not disturbing it.A good way to find out about that is over at the flooring forum. You can always take small sample pieces and have them tested.There should be a hazardous materials dept. in your town or county,usually found in the govt. section of the phone book.You can also google asbestos and find testing depts in your area.
