What if life balcony leaks water?

This problem can be big or small, so we must pay attention to it. If the problem is not solved, you must know your rights and interests and go to the property to complain. This is obviously not waterproof; The main reason for the leakage of balcony windows is that there is a gap between the windowsill and the wall, and the water in the window frame leaks into the gap. 1. Check the position of the drain hole in the window frame groove. If it doesn't face the windowsill, please seal the original hole and drill it again. 2. Check the sealing conditions of window frames and windowsills outside the inspection site. If there is a gap, knock out all the original sealing places and shovel them off, then buy a weather-resistant glass glue soft seal, seal it with cement mortar, make it waterproof, and then stick tiles. I believe there will be no leakage after such treatment.
