Interior Drywall Water Damage
Whenever I see this type of interior drywall water damage, I automatically
assume that water is somehow getting in between the gap where two pieces of
drywall are butting together, vertically. Water somehow soaks into the gap
and works its way down to the bottom, usually leaving something like this on
the wall as the gap fills up with water, then soaking into the drywall and
drywall finishing materials.
The picture below shows you what it
would look like before the drywall is finished, giving you a better idea
what I'm talking about.
Drywall damage like this is usually easy to
repair, but you will need to find out where the water is coming from and
make the necessary repairs, to stop the water from entering the home, before
fixing the interior damage.
