Hi all. I just bought a house with a drywalled garage. It's a raised
ranch, so the garage is tucked into the corner of the house. The
existing drywall has never been painted. Looks like it's been there
at least 10 years.
There's a long strip of what appears to be water damage directly above
the garage door, and exactly the width of the door, which is kind of
strange. At first we thought there'd been a leak (from a heat pipe in
the bedroom above?), but there's no sign of that. Instead, we think
maybe the garage door itself caused the wet strip... maybe rain
spattered on it while open, hitting the ceiling.
Anyway, there's a distinct musty smell in the garage. We wonder
whether, because the drywall has been unpainted/unsealed for so long,
the sheetrock may have become damp over time and whether mold
might be an issue. Any suggestions on what to do?
Thanks in advance,
