Hey All! My Husband and I own a townhouse for almost 5 years now, and have noticed a strange leak. We've had plumbers and contractors come and look at the problem and "fix it", only to see the leak is back in 6 months. The weird thing to me is that the walls are wet only in the stairwell? not on external walls, and also not on the ceiling, only from the floor molding and up about 6-12 inches. Additionally odd, is that the carpet and floors have never been wet. only the walls. They are only damp on and off, and with no real pattern that I can notice, like, after the tub is used or after it rains. Anyone had or seen a similar problem? if so how was it resolved. All advice welcome! Thanks!
