Siding over Asbestos
Vinyl siding retrofit over asbestos
This is a recommendation from the Vinyl Siding Institute after
discussions with Federal EPA officials. Because local regulations
supersede federal regulations, local EPA officials should be
contacted in the area where the work is being done.
The most desirable practice is not to disturb the existing siding on
the home. Apply sheathing over the existing asbestos siding, and
then apply vinyl siding over the top of the sheathing. The sheathing
will serve to flatten the wall and also retain any breakage of the
cement asbestos siding. Nails should be long enough to penetrate
through the sheathing and existing asbestos siding and into the
wall studs.
If there is a need to level or flatten a wall, apply furring strips over
the sheathing.
In the case where the homeowner wants the existing cement
asbestos siding removed completely, removal should be done
by a professionally trained asbestos removal crew.
Please note that some jurisdictions require all asbestos removal
to be performed by a trained asbestos removal crew.
Historic Restoration
Vinyl Siding Institute recommended guidelines
If a building is in an historic area or has been designated an
historic building, be certain that approval for the use of vinyl siding
has been obtained from the local historic society. This applies to
building additions as well.
Before proceeding to re-side an historic building, the building
should be examined for moisture, insect infestation, structural
defects and other problems which may be present. These
problems should be addressed and the building pronounced
“healthy” before re-siding with any material.
Do not damage or remove the original siding. If at all possible, do
not alter the original structure so that the application of vinyl siding
is reversible (i.e. the original would remain intact and some time in
the future, if desired, the vinyl siding could be removed). Exception:
“In cases where a non-historic artificial siding has been applied to a
building, the removal of such a siding before the application of vinyl
siding would, in most cases, be acceptable.” (Preservation Briefs,
Number 8 - U.S. Dept. of the Interior—1984)
