On the waterproof problem of windows

Hello, I don't know what you mean by waterproof, whether it's glass waterproof or the waterproof between the window frame and the wall. If it is the latter, you can report the maintenance to the local quality supervision bureau first. If it is not well maintained, you can complain to the local quality supervision bureau. Most of these water-resistant problems are caused by window installation defects. When installing a window frame in normal construction, holes will be punched around the window frame, the gap between the window frame and the wall will be filled with foaming agent, and the top will be closed with mortar. There is also the most important place, that is, before the household acceptance of construction, it is necessary to do a water spraying test on the outer window, and the phenomenon of water leakage and water reversal should be dealt with in time, otherwise it will not pass the acceptance. So it is the most correct way for you to find property maintenance now.

If you are afraid of trouble and deal with it yourself, I suggest you scrape white the junction of some window frames and walls indoors with waterproof putty, and then glue the junction of windows and walls.

If the glass is waterproof, there is water seepage at the joint between the glass and the sash frame, or between the sash and the frame. The former is that the tape and layering of the window sash are not installed properly, and the latter is that the sealing strip between the window sashes is not installed properly. In addition, check whether the outlet hole of the gutter of the lower window frame is blocked. I hope this helps.
