Just finished remodeling a house and when I want to look at a floor near a
sliding glass doors I see what looks to be a fairly bad case of cupping. It
rained very heavy here in So Ca about 3-4 weeks ago and I suspect that the
channel of the door had debri in it and the water did not drain out and
drained onto the hardwood floor. The floor did not look wet though and
there are carpets and such near it that would have obviously been wet???
Will condition like this reverse itself when the wood completely dries out
or is the wood ruined. Is there anything that I can do? I would hate to
have to have it sanded down now after just finishing the whole floor. BTW,
the sliding glass doors have little plastic weep plugs on the outside. I
was told these were to stay on but wonder now if that was correct info.
Wait for the wood to dry out prior to doing much of anything. Can't
imagine why the plugs would remain on the outside of the bottom, but I
can't imagine a number of things.

Once hardwood cups it won't return to its original state. Depending
on the floor and the severity of the damage, it's possible to sand
just that patch flat and refinish it. I've done it before and it's
tedious. Basically, you refinish within the area demarked by the
boards' sides and ends. But it's definitely better to rent a power
screener and add another coat to the whole floor.
Usually, cupping of a finished floor will be because water wicked
underneath to the unfinished side. Check for any gaps in the
caulking between the door and the edge of the floor. The natural
movement of wood, especially new wood, to climate changes could have
opened up a void. Also check the caulking outside the door... not
just at the bottom but around the the top and sides. Also around the
facia over the door. Water seepage can be very tricky. You could
have rain dripping down the outside of the house, into a gap in the
siding, down to the header and down a jack stud where it's pooling on

I suspect the door was not installed properly. I would get your contractor
over there and bitch to him. There should be caulking under the threshold
so moisture does not get into the house. Try to get a copy of the
manufacturers installation instructions.
