Cement Asbestos Siding

This was one of the promised "permanent, no maintenance" siding products. When in good condition, it is best left alone. We have not come up with any acceptable materials which can be used to patch or repair this material. The cement asbestos board does become brittle and subject to cracking over time, and will most likely have to be covered or removed at some point by an asbestos abatement company at high cost (+/- $2.50/sq.ft.). For more information about cement asbestos siding, asbestos abatement, and guidelines for homeowners who wish to undertake the removal of cement asbestos siding themselves, please contact the Puget Sound Air Pollution Control Agency, (206) 343-8800.
