Has anyone experienced water damage to an exterior wall and not been able to determine the source.
Long story short:
We have repaired an older Signature with bad enough water damage to cause both the exterior and interior wall wooden sub-structure(luon) to rot which led to delamination which cracked the exterior fiberglass and the interior vinyl wall paper. We knew where the water came from, the window.
Have you pulled the window out? Window seals can leak, and the window frame can leak. Previous owners sometimes accidently leave windows open when it rains. On our Monacos, when the window(s) is removed, it is plain to see that when the coach was built they made no attempt to prevent water from getting into the wall if water somehow got beyond the window and/or its frame. If water gets into the wall somehow it will eventually destroy the wood in the wall(s) and the fiberglass and/or wallpaper that it is glued to.
If there is any water inside your wall, it needs to be removed and eliminated forever asap. Wood and water don't mix well. If it is possible to do the repair from inside the coach, remove the wall paper, remove the wet wood(luon), remove the wet styrofoam, if the wood(luon) on the other side of the styrofoam is also wet it will need to be dried out if it hasn't started to rot. If it has, then it to will need to be removed and replaced, then everything put back together in the opposite order with new. If the repair work has to be done from the outside, it's even more difficult and costly because of the paint and body work envolved.
Most RV shops won't tackle these type of jobs. Requires too much time and attention to detail to do it properly.
We hope this helps.
