In a fully-insulated home in N. California SF Bay Area (very temperate
climes) is it common to seal the back side as well as the front of
kickboard
molding? The owner is insisting that the back side be sealed also with
organic varnish or polyurethane.

Recommendations?

Thanks.

Do you mean a molding as in "baseboard"?
If you don't have carpet, you can seal the bottom with silicon caulk after
its nailed up. *The top can always be caulked.

Silicon caulk is a bad idea around painted surfaces - it interferes
with the paint adhesion. Siliconized (paintable) caulk is better.
