Hiding Drywall Gaps
Crown molding can cover a world of ills
My 1979 post-and-beam house is made from pine
timbers. On the ceiling, the drywall fits between the timber rafters,
and a bead of sealant was applied where drywall meets wood. The sealant
seems to be pulling away, leaving ugly gaps everywhere. Any ideas for a simple fix?

Tom says: Given the age of your house, the timbers have dried out as much as they're going
to. But even the most well-seasoned wood expands and contracts with
changes in humidity, and trying to seal gaps between drywall and timber is a lost cause. Instead, I'd cover the gaps with ¾-inch quarter-round molding, fastened to the timbers — not the drywall — with 4d or 6d finish
nails every 12 to 16 inches. Don't put it too tight against the drywall;
you want the molding to move with the beam and not to scrape against the ceiling. To make that molding "invisible," paint it the same color as
the ceiling before installing it.
