Should the property be responsible for the maintenance of the balcony external wall leakage?

During the warranty period, the developer is responsible for the maintenance, and the problems existing in the property collection are reported for repair. Outside the warranty period, the external wall of the balcony of a single owner leaks water, which can be maintained by the property. Serious leakage, you can apply for maintenance funds. Therefore, in case of leakage of balcony exterior wall, we must first determine whether the house is under warranty.

Common causes of balcony leakage 1, dripping eaves damage: when changing windows or closing balconies, rainwater will penetrate into the room through the joints between windows or window frames and external walls due to improper operation. There is a dripping roof at the window. When the balcony was rebuilt, some owners moved the window out and pressed it on the dripping eaves, so that the rainwater would enter the gap between the window frame and the wall and pour water from the upper part of the window. The solution is to install dripping eaves at the mouth of the cave (through connectors or adhesive arching, etc.). ), let the water drain smoothly.

2, the seal is not strict: some windows are not glued in the lower or middle part, or the glue is not chamfered, resulting in water infiltration into the room. Ok, wait until the rainy season is over and the water vapor in the window frame is drained before re-gluing. Because steam will not only affect the sizing effect, but also affect the service life of glue. During installation, some walls are sunken, and workers will suggest plastering the sunken parts. Although it can achieve a certain waterproof effect, it has little effect. He suggested that the sunken place should be filled with glue before making the cement slope.

3. The drain hole is blocked: there is a drain hole at the bottom of the plastic steel window, but it will be blocked if you don't pay attention when installing it. Once it rains heavily, the water in the window frame will seep out from the place where the expansion bolt is installed. The solution is to check whether the windows are connected with expansion bolts. If this is the case, glue can be temporarily added to play a sealing role, and then glue can be applied again after the rainy season. If it is fixed under the glass, you have to wait until after the rainy season, open the glass, clear out the water in the window frame and stick it again. When installing the window, use the connector at the bottom, which will not damage the inner window frame or cause water seepage.
