I have wood siding on my 12 year-old home.
Several years ago, I decided to seal these seams, and put putty on some
of the seams on the east side, and paint over it.
A few weeks ago I noticed that one board, right underneath the my
laundry room window, has a bulge underneath it big enough to get two
fingers underneath it.
We don't get much rain in my area, and not much snow, but we did have
our share of fog, and I noticed for about a week it was so bad that the
house dripped of moisture. However, the area is underneath a deck, so
it was dry.
I am hoping when it warms up that the board will relax, so I can screw
it to the wall, and not replace the entire board.
Does anyone know what the problem is?
