What to do if the window is leaking Causes of window leakage Window leaking rain repair bay window b

Window Leakage Causes and Solutions:

1. The dripping eaves are damaged: the window openings have dripping eaves, and when the balcony is renovated, some owners move the windows outward and press them to the dripping eaves, and the rain will enter the cracks between the window frame and the wall, and the water will flow from the upper part of the window. Solution:

Add drip eaves at the entrance of the hole (through various forms such as connectors or glue bulges) to make the water drain smoothly.

The drainage hole is blocked: the bottom of the plastic steel window is equipped with a drainage hole, but if you don't pay attention to it during installation, it will be blocked, and once there is heavy rain, the water in the window frame will seep from the installation bolt.

Solution: Check whether the window is connected by an expansion bolt, if it is a temporary glue to seal it, and then re-glue it after the rainy season. If it is fixed under the glass, it is necessary to wait until the rainy season has passed, open the glass, remove the water in the window frame, and then re-apply the glue.

2. Water leakage caused by loose and deformed windows: Water leakage caused by loosening between windows and frames is the most common cause. On the one hand, when the door is closed, the window will also resonate and vibrate, and the gap between the window and the wall will become larger and larger over time; On the other hand, it is caused by the poor quality of the window, the strength of the poor quality window is not enough, it is easy to deform, and the mortar layer at the edge of the window frame will crack and fall off soon after use, which will cause leakage.

Solution: If the window itself leaks due to quality problems, it is necessary to repair or replace the window directly. The quality of the purchased window frames, window sashes, sealing strips, etc. should be passed, and the waterproof sealing materials used should have material quality certification documents to ensure that the quality of the materials meets the requirements, and do not choose inferior sealing materials.

3. Water leakage caused by damage to the waterproof layer of the wall near the window: In an old house with a long age, the waterproof layer of the wall around the window is damaged and prone to water leakage; In addition, when the windows are replaced in the renovation of the old house, the damage of the waterproof layer of the exterior wall caused by the unprofessional removal of the windows, and if it is not repaired in time, it is very likely that there will be water leakage after the installation of new windows.

1. If there is a gap between the window and the wall, it should be filled with foam caulk.

2. If inferior waterproof coating is used, the outer waterproof coating should be reinforced.

3. If the sealing treatment between the glass and the window frame is not in place, the first-class glass should be replaced and a thick special glass glue should be put on it.

4. The edge outside the window sill is inclined downward, and it should be changed to a yearning angle.

5. The window is in the form of left and right push and pull, and the impurities in the guide rail should be cleaned up, or a few drainage holes should be made outside the bottom of the guide rail.

In the rainy season, frequent rain, many people are troubled by window leakage, rainwater flows down the window into the home, serious cases may lead to furniture moisture and mold, etc., so what to do with window leakage, today home improvement network will introduce the causes and treatment methods of window leakage, let's take a look.

1. The waterproof layer of the wall near the window is damaged, resulting in water leakage

In older houses, the waterproof layer of the walls around the windows is damaged, and water leakage is likely to occur; In addition, when the windows are replaced in the renovation of the old house, the damage of the waterproof leakage layer of the exterior wall caused by the unprofessional removal of the windows is not repaired, and it is very likely that there will be water leakage after the installation of new windows.

Solution: Redo the waterproofing layer of the window wall. For balconies with serious leakage, the waterproofing should be redone, especially the waterproofing of the top surface and the wall.

It is also possible to add a water baffle above the wall to reduce the impact of rainwater on the infill layer between the window and the wall. When repairing, good sealing materials should be selected, and all leakage points should be carefully sealed.

2. Water leakage caused by non-standard window installation

When the window is installed, the lintel and window sill do not make a drip groove and the slope of the flowing water; The outdoor window sill is higher than the indoor window sill board, and the plastering layer of the window sill plate does not cause water leakage due to defects such as downstream slope or slope facing inward and window sill plate cracking.

Solution: Retrim the window sills. The outdoor window sill should be 20mm lower than the indoor window sill plate, and set up a downstream slope to smooth the rainwater drainage.

The gap between the window frame and the indoor window sill plate must be closed with weather-resistant and highly elastic sealant to ensure water tightness and prevent leakage. The lintel and window sill should be made with sufficient drip groove and flowing water slope.

3. Water leakage caused by poor drainage of window groove drainage holes

Some windows may not have drainage holes, especially sliding windows, all the rainwater accumulates in the sliding frame and cannot be drained, and it seeps into the house when it is full; Or when the external window sill is tiled, the drainage hole is blocked, and the rainwater in the sliding frame slot seeps into the wall and causes water leakage; In addition, after a long period of use, the drainage hole may be blocked by stolen goods, resulting in the water flow not being discharged in time.

Solution: Refurbish the gutter. For leaks caused by clogged gutters in the window frame, keeping the gutters open can solve the problem. If there is a problem with the location of the drainage hole, the original hole needs to be closed and reopened.

4. The window is loose and deformed, resulting in water leakage

Water leakage caused by loosening between the window and the frame is the most common cause. On the one hand, when the door is closed, the window will also resonate and vibrate, and the gap between the window and the wall will become larger and larger over time; On the other hand, it is caused by the poor quality of the window, the strength of the poor quality window is not enough, it is easy to deform, and the mortar layer at the edge of the window frame will crack and fall off soon after use, which will cause leakage.

Workaround: Reprocess the seams. Inspect the joints between the windows and the walls, remove the original aged or damaged sealing materials, and then treat the base layer to dry and seep clean and straight.

For the large gap between the window and the wall, fill it with styrofoam, and the inner and outer sides, the window frame and the window sash must be filled with glue and sealed.
