Asbestos is dangerous when it is damaged. If the home has damage such as crumbling drywall, insulation falling apart, water damage to popcorn ceiling, or any visible damage then you want to test for asbestos. If you are planning to remodel your home which will cause disturbance to the building materials you want to test for asbestos.
If there is no materials damaged in the home and nothing is being disturbed you do not need to have your home tested for asbestos. Material that is in good condition and will not be disturbed should be left alone.
