What should I do if the windowsill leaks?

1. The dripping eaves are damaged: there are dripping eaves 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 the water would be poured in from the upper part of the window. Solution: Install drip eaves at the entrance of the cave (through various forms such as connectors or expansion), so that the water can be discharged smoothly.

2. 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 penetrate inward from the installation place of the expansion bolt. Solution: Check whether the windows are connected by expansion bolts. If there is, temporarily glue it to seal it, and then glue it again after the rainy season. If it is fixed under the glass, it will be removed after the rainy season, and the water in the window frame will be cleaned and resized.

At the same time, the waterproof sealing materials used should have material quality certification documents to ensure that the material quality meets the requirements. Don't choose inferior sealing materials.

The waterproof layer of the wall near the window is damaged and causes water leakage: in an old house with a long room age, the waterproof layer of the wall around the window is damaged and prone to water leakage; In addition, when replacing windows in old houses, unprofessional window removal caused damage to the waterproof layer of external walls. If it is not repaired in time, water leakage is likely to occur after installing new windows. Solution: The window wall itself leaks water. The solution is to knock on the outer wall and repair it. Check whether it is firm after repair, and remember to lay waterproof layer.
