Mildew in the Closet
Q: Our closets have plaster walls, and they have mildew problems.
Is there anything we can do to correct this?

Is there anything we can do to correct this? Will putting insulation and
drywall over the plaster help?

Tom Silva replies: Covering up the mildew won't solve the problem, which I
suspect is an air leak somewhere that's creating condensation. Moisture is building up inside the wall and when the temperature rises, mildew begins to grow. This could be because the insulation inside the wall
is wet or maybe there's a lack of insulation there. Only further
investigation of the source of the moisture will stop the mildew's
growth. When you've solved that riddle, the mildew should stop growing and you'll be able to clean up the current mess with bleach.
