Similarly, it is asked, how do you seal a leaking window frame?
Remove damaged exterior caulking, clean the window frame and recaulk. Check the gasket between the window frame and the glass. Re-seal the glass to the gasket with clear silicone caulk. Make sure the sill at the bottom of the window frame is pitched downward to drain water toward the exterior.
Also Know, can water leak through window frame?
Window leaks can result from a structural failing elsewhere in the home, such as an opening in the roof, upper floors, or siding. If you notice water stains on the wall above the window or along the top or bottom of the frame, this usually means there is a leak inside the walls.
Pry off the trim from the leaking area with a pry bar, and inspect the gap between the window and frame. You may be able to fill it with caulk. If you see rotten wood, chip it out with a putty knife, and fill the void with epoxy wood filler.
