When the window leaks, how should it be solved?
Generally to first find the cause of the leak, and then the right medicine, today summarized four common reasons and their solutions, to share with you:
1、 window installation is not standardized to cause water leakage
Window installation window lintel, window sill did not make the drip groove and water slope; outdoor window sill higher than the indoor sill plate, the sill plate plaster layer does not do the water slope or slope towards the inward and the sill plate cracking and other defects caused by water seepage and leakage.
Solution: Repair the window sill.
Outdoor window sill should be lower than the indoor sill plate 20mm is appropriate, and set up the water slope, rainwater drainage. The gap between the window frame and the indoor sill plate must be closed with weather-resistant high elasticity sealant to ensure watertightness and prevent leakage. Window lintel, window sill should make enough drip groove and water slope.
2、Water leakage caused by loose and deformed windows
Leakage caused by the looseness between the window and the frame is the most common cause. On the one hand, the window will also produce resonance vibration when closing the door, over time, the gap between the window and the wall is getting bigger and bigger; on the other hand, it is caused by the quality of the window is not good enough, the quality of the window is not strong enough, prone to deformation, the use of a short time will be the window frame side mortar layer cracking, falling off, which will lead to leakage.
Solution: Reprocess the joints.
Check the joints between the window and the wall, the original aging or broken sealing material removed, and then the grass-roots level to deal with clean and straight. For windows and walls with larger gaps filled with styrofoam, inside, outside and window frames, window presses must be full of glue to seal up.
3、Window groove drainage hole poor drainage caused by water leakage
Some windows may not have a drainage hole, especially sliding windows, rainwater all accumulated in the sliding frame grooves can not be discharged, full of seepage into the house; or outside the window sill tiling did not pay attention to the drainage holes blocked, sliding frame grooves in the rainwater all seeped into the wall and lead to leaks; in addition, the use of a long time, the drainage holes may be blocked by the loot, resulting in the flow of water can not be discharged in a timely manner.
Solution: re-trimming the drainage groove.
For the window frame drainage groove blockage caused by water leakage, keep the drainage groove can solve the problem. If there is a problem with the location of the drainage hole, you need to close the original hole, re-open the hole.
4、 water leakage caused by damage to the waterproof layer of the wall near the window
Longer age of the old house, windows around the wall waterproof layer damage prone to water leakage; in addition, the old house remodeling replacement windows, demolition of windows unprofessional caused by the waterproof layer of the outer wall of the breakage, if there is no timely repair, after the installation of the new windows, there is likely to be a water leakage.
Solution: redo the window wall waterproof layer.
For the more serious leakage of the balcony, waterproofing should be redone again, especially the top surface as well as the waterproofing of the wall. You can also add a water barrier above the wall, which can reduce the impact of rainwater on the filler layer between the window and the wall. Repairs should be made with good sealing materials and all leaks should be carefully sealed.
