However, after the old windows were changed to plastic-steel windows and aluminum alloy windows, there was a problem of wall leakage in all directions. The location of the leaking water is generally under the window sill, and when it is severe, the wall skin expands, pulverizes, and falls off. However, finding the cause of water leakage is extremely difficult. Under normal circumstances, maintenance personnel pay attention to the sealing of the outer wall sill and the form, the sealing of the inner wall sill and the form, the drainage hole outside the window frame is unblocked, etc., which is very easy to check and handle. However, the real cause of leakage is not here.
If your window sill leaks, try a test: block the drain hole in the lower part of the window frame with clay or other things, and then inject water into the window frame. After a while, if the water surface does not decrease, then there is no Problem. However, under normal circumstances, there is no water in the window frame, and there is no time for it. This is the real reason for the leakage.
Originally, the plastic windows and aluminum alloy windows used for the transformation of old windows could not seal well at the right angle joints. The water in the window frames entered the wall along the joints, which was the cause of the leakage of the windowsill.
Finding the reason is easier. Clean up the dirt at the corner and apply a layer of sealant to solve the problem. After the painting, we must also do a hydrostatic test. If it does not leak, congratulations, the future troubles will not exist.
