After the latest rainfall, the wall in one of our bedrooms started to leak. There was a bubble that was forming along the same line as the bottom of the window sill. The leak seemed to start about 3 inches from the window and spread hoizontally along the wall. There are no pipes along the wall as it faces the back of the house. We popped the bubble and peeled the paint away and there is a small gap between the sheets of drywall about 2.5in long. The water is definately coming through that gap but I cant seem to find the origin. The ceiling is dry and clean and there is no dampness below the gap except for where the initial water ran down. Could the water be coming in from the window (it is pretty old).

Without seeing the issue determining the source of a water leak is difficult as it often involves some investigative work. Some leaks are obvious and others are not. From what you have posted it would appear that the window could very well be the source. I would check the window from the exterior caulking deficiencies and integrity.

Hope this helps.

Hi Brian,

It sounds like it could be the window. Is it a posibility to have the window changed?

Since it is an old window, and new ones would save you in heating and air conditioning expenses, on top of the damage that is occuring due to the possibility of a faulty window(caulking etc..), I would suggest calling in a window company to look at the area in question. They will be better suited to tell you your options and get things made right for you.

Good Luck,
