I havd a small roof leak thru the main level into the basement (only
noticed during extreme down pours). I am not worried about the basement
because the water seemed to only be exiting through a non used, but
wired electrical box. so it seems it was just following a wire down. I
have since had a new roof installed and the leak is resolved. However,
on the main level below where the leak was is a closet in the foyer.
There are some paint cracks and bubbled paint there that indicates that
some water came through there. I took up the baseborad in the closet,
and cut out a small chunk of drywall, and did not notice anything
significant. Should I replace the drywall knowing that it got
saturated at some point, or would it be OK to just sand it down and
If this was an exterior wall, I'd be more concerned about the insulation
getting wet/ineffective, and creating a cold spot where condensation is
likely to form.
You did the proper thing, fixing the leak first. I'd try the cheapest
solution first- scrape, check for mushy spots with an icepick, repair those
with mud, paint with Kilz or similar, and monitor it for a few months. If
you don't get any visible bloom, and no cold or mushy spots when you poke at
it with your fingers, I wouldn't worry about it. If it stays dry, any mold
that is there will likely stay dormant. And all the scary stories aside,
unless you have allergy sufferers in the house, typical household molds
(that are present in almost all houses, BTW) are almost never dangerous or
