The EPA beganc a gradual phase out of asbestos in the mid 1970's, since it was linked to a serious lung and intestinal disease, a rare cancer - malignant mesothelioma. Asbestos is a natural substance derived from serpentine stone and has a substantial resistance to high temperatures, which originally made this product worthy of broad commercial use

There are still products existing in homes built through 1985, when the asbestos phase out was complete. Whether or not low exposure to asbestos over a long period is a health hazard or cancer causing has not been determined. Having said that, testing is simple and inexpensive and any finding that is considered a concern can be managed.

Some old duct work may have a composition that includes asbestos, which will be ejected into the home environment as the ducting deteriorates. Metal ducting may be wrapped with an asbestos insulation that should be removed. An abatement contractor may charge $6.00 - $12.00 a lineal foot for removal.

The EPA can be contacted for free instructions on how to collect a sample that can be tested by a recommended lab for about $50.00.
