Q: We have a ranch home in the San Francisco Bay Area and over the years we’ve replaced some of the exterior siding with plywood. When we did this work, waterproof paper was installed beneath the plywood. The exterior paint is about 8 years old now and the plywood siding is checking quite a bit. One area of the plywood has some dry rot as well.
We are considering having stucco applied to the exterior. The contractor says he will remove the battens and put a waterproof membrane over the plywood siding then apply three coats of stucco on top of the wire.
