A Leaking Window is a problem that many householders will encounter at some time. The Leaking Window problem normally appears between the frame and brickwork due to expansion and contraction of the two materials. Wooden frame windows tend to have a higher rate of leaks due to its flexibility.

During Irma, my first floor's windows (north facing) about 8' on each side were leaking rainwater from the top of the window, similar to the manner of leaking in the video by Ada Lam above. The exterior door in between the windows had water entering the wall and you can see stains around the door still. When you develop leaking windows, ports or hatches, no surface remedy is going to solve the problem. The leaks usually develop because the seal between the window frame and the fiberglass part of the boat has broken. The break in the seal can be so small that you can't even see it.

Often, water leaks at a window result from a breakdown in the connection between the window frame and the wall. To prevent leaks, caulk the window where it meets the exterior siding. If the window is surrounded by wood trim, use a high-grade polyurethane caulk to seal all gaps between the trim and the siding (and the trim and the window).
