Garage Leaking Water Through the Walls
If the leak is in close proximity to a door or a window, it may be another flashing issue, this time around the top of the door or window frame. Because the exterior frame of a door or window usually extends a little farther than the siding and because installation requires that the siding be cut, water leaks are likely to occur here. Flashing above doors and windows is usually made from thin sheet metal, painted to match the color of the house trim. If the flashing is bent, damaged or nonexistent, water can run down the siding and enter a crack above the window or door.
