What s going on with water seepage from doors and windows? What to do if water seeps from the window

In spring, the weather is humid, the rain is continuous, and the air humidity becomes larger, if the aluminum alloy doors and windows are not maintained and cleaned, it is very easy to undergo adverse changes, which will affect the service life of doors and windows products, and will also cause deformation of doors and windows, water seepage and other phenomena. The old carpenter Luban doors and windows talk about the situation and solutions that cause water leakage in doors and windows!

The material and accessories are unqualified:

The material of the lower frame is too small, and it is not raised according to the regulations, and some even bury the window frame in the plastering layer of the window sill, so that the rainwater is easy to infiltrate into the room.

The cross-sectional size is small, the material is too thin, the nodes are made of plane splicing, and the gap at the joint is too large. In order to reduce costs, the profiles selected are shoddy. Some will shake when the doors and windows are opened, resulting in cracks between the frame and the wall due to shaking, which is not only easy to cause leakage, but also affects its use function.

The quality requirements are not met during the installation process

The upper part of the window does not make drip lines or olecranons according to the regulations, and the slope of the window sill is too small or there is no drip eaves, so that when it rains, the rainwater slowly leaks along the wall and flows into the room.

The sealant is too thick to block the drain hole, and the window sill appears high and low, so that the rainwater in the push-pull groove of the window frame can not be removed in time, resulting in rainwater infiltration into the room.

The connection with the wall of the opening is not sealed enough

The rubber sealing strip and water-blocking brush strip on which the glass is installed are not in place or fall off.

The glass glue on the exterior wall is not well constructed, resulting in water seepage at the joints.

The gap between the door and window frame and the wall is not sealed with sealant or the process is rough, and the notch between the frame material and the corner of the wall is not cleaned up before the dust on the surface of the glue, resulting in the place becoming a weak link in waterproofing.

Door and window water seepage solution:

Check whether the exterior wall glass glue is well constructed, sometimes a small hole can also cause rainwater to seep into the home.

If there is a water leakage caused by the gap between the window frame, the wall and the window sill, remove the original seal and fill it with weather-resistant glass glue for sealing. For the gaps between the window frame and the window sill outside, fill in the weather-resistant glass glue for sealing, and then seal it with mud mortar for waterproofing.

Leaks caused by clogged gutters in the window frame can be solved by keeping the gutters unobstructed. If there is a problem with the location of the drainage hole, the original hole needs to be closed and reopened.

The windows are installed in the drip eaves, do not install too many windows outward in order to expand the indoor space, without the drip eaves, the probability of window leakage will become larger. If the original house does not have drip eaves, you can simply dig one out, or add a layer of iron sheet to the window eaves.

For doors and windows that have been installed for more than a few years, the maintenance of the exterior wall glass glue should be carried out, and the glass glue should be checked for cracking, so as to repair the cracks in time.

There are a variety of reasons for water seepage from doors and windows.

1. Door and window merchants.

1. When the doors and windows are installed, the waterproof silicone is not good, and some have leaks, 2. The silicone is too thin and cracks for a long time, 3. The quality of the silicone is not up to standard, 4. The silicone and the exterior wall are degummed.

Second, the reason for the wall, 1, the current external wall insulation layer is very common, the installation of doors and windows is generally silicone waterproof and the surface layer of the insulation layer for bonding waterproof treatment, if there is water seepage between the insulation layer and the concrete, it is difficult to deal with, need to remove the insulation layer and then re-hit the waterproof silicone. This fix is more cumbersome.

2. The leakage caused by cracks on the concrete wall, the leakage in the wall needs to be waterproof for the entire exterior wall, and it is useless to rely on doors and windows alone!

Thinking of these for the time being, others are welcome to add!

Causes of window leakage:

1) The window may not have drainage holes, especially the sliding window, all the rainwater accumulates in the sliding frame groove and cannot be discharged, and it seeps into the house after it is full, or the drainage hole is blocked when the external window sill is tiled, and the rainwater in the sliding frame groove will all seep into the wall and cause water leakage.

2) The installation of windows is not standardized.

3) The wall itself is leaking.

Workaround:1The sealing strip of the window must be a whole piece, and the interface must be selected on the upper part of the window, preferably connected with glue. Good sealants smell like natural rubber, while bad ones are hard, crackable, and have a pungent smell.

2.If there is a water leak caused by the gap between the window frame and the wall or window sill, the gap can be resealed. For the gap between the outside window frame and the wall window sill, it is best to remove the original seal and fill in the weather-resistant glass glue for sealing; For the gaps between the window frame and the window sill outside, it is best to remove the original seal, fill in the weather-resistant glass glue for sealing, and then seal it with mud and mortar for waterproofing.

3.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.

When renovating the balcony, some owners move the window outward and press it to the drip 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: Install drip eaves at the entrance of the hole (through connectors or glue bulges and other forms) so that the water can be discharged 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.

Water leakage due to loose and deformed windows: Water leaks caused by loosening between windows and frames are 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.

Water leakage caused by damage to the waterproof layer of the wall near the window: In older houses, 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.

Analysis of the causes of water leakage in balcony windows, there are 6 main points:

1. In a newly built building, if there is a leakage in the window, it is likely that there are cracks in the insulation and plastering of the exterior wall, and the rainwater flows in along the cracks. If you don't find a crack in the exterior wall on your floor, it must be a crack in your upstairs, and sometimes a crack in the parapet can also cause the window to leak.

2. The drainage hole on the window is blocked, resulting in rainwater or condensate on the window not being drained out, and leaking from the junction between the side seal and the lower frame.

3. The drainage hole on the window is blocked, resulting in rainwater or condensate that cannot be discharged, and seeping down from the expansion screw of the installed window below causes the window sill to leak.

4. The window is fixed, the glass sealing strip is not well sealed, or the sealing strip is aged for a long time, resulting in rain or condensation water infiltration.

5. The current heat-insulated bridge window glass sealing is generally sealed glass glue, which is easy to leak if it is not played well.

6. The window frame and wall sealant are not laid.

If it's caused by a blocked drain, unclog the drain. If it is caused by poor sealing of the glass, find the part that is not well sealed, clean it up, and re-apply the sealant. If it is due to the fact that the form and the wall are not properly sealed, re-apply the sealant.

1. Whether it is a community house, 2. Whether the window is sealed by the developer or by itself. 3. Check the water that comes in from the window, if it is a residential house, the window is still sealed by the developer, then just look for the property. If it is a window that you seal, find the person who seals the window for you, generally the window water seepage is the place where the window frame and the wall are in contact with the glue is not good, and the glue can be re-glued, but if the glue is not good, then you have to find someone to check the reason on the spot.

bald tail problems; There are wooden windows, aluminum alloy windows, plastic steel windows, sliding windows, and casement windows. Explain what kind of window leakage, everyone comes up with an idea, and maybe it will be solved. Aren't you too general?

If the gap in the interface of the window is relatively large and cannot be bonded by other methods, then you can buy some sponges to stick to the window, and then try to cover the window with plastic, the plastic texture is very dense, impermeable, and can also absorb heat, and can also achieve the effect of heat preservation.

If there is a gap between the window frame and the wall, you can try to fill the gap with styrofoam, and then use cement to wipe these gaps and reinforce the styrofoam.

The common cause of water leakage on the wall around the window is the loosening between the window and the frame, and the window should be repaired or replaced directly. It should be noted that you should not choose inferior waterproof sealing materials. Be sure to buy windows, window frames, sashes, and seals that pass the quality test, and the materials purchased should have a certificate of qualified quality to ensure that the quality of the materials meets the requirements.

Water leaks from doors and windows can be treated in this way.

Seal the balcony window loosely deformed and cause water leakage

Water leaks caused by loose sealing between balcony windows and borders are 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 broken sealing materials, and then clean and straighten the base layer. 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.

The installation of sealed balcony windows is not standardized, resulting in water leakage

When the window was installed, the window sill did not make a drip groove and a slope of running water; The outdoor window sill is higher than the indoor window sill board, and the plastering layer of the window sill plate does not leak 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 a downstream slope should be set up to allow smooth 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 window sill should be made with sufficient drip grooves and flowing water slopes.

Fill the window frame seams with sealant outside.

Hello, the simple way to deal with the leakage of the window sill in general is:

1. Clean the base surface and moisten it thoroughly.

2. Fill the gaps with caulk if there are obvious cracks.

3. Brush three to four times with acrylic high-elasticity anti-crack waterproof coating along the aluminum alloy frame, and the next time the surface can be painted after each surface drying.

Note: If there is an anti-theft net, the nail that fixes the anti-theft net must be sealed with paint.

In fact, it is better to find a professional to help you deal with it! In the future, choosing a better decoration company before decoration will also reduce this kind of problem!

1. If the gap between the window frame and the wall is less than 5 cm after installation, the gap can be filled with styrofoam, and then covered with waterproof glue, which can not only fill the gap, but also ensure that there will be no water seepage;

2. If the gap is very large, you can choose to fill the gap with bricks or cement slurry, so as to ensure that the gap between the wall and the window frame is solid and impermeable. This is generally a remedy after installation, it is best to grasp the size when measuring, and try to keep the gap within 1-2 cm;

3. Fill the door and window with rock wool between the wall and the outer layer with cement, and then paste wallpaper or paint. This treatment is due to the fact that the outer layer is smoothed with cement. After a long time, due to the change of displacement, there will still be cracks in the cement at the edge of the door and window;

4. The doors, windows and walls are first filled with polyurethane foam glue, and sealed with silicone sealant externally. This method solves the crack problem. However, when using silicone adhesive, attention should be paid to color matching.

Hope the above is helpful to you.

The fan opening process is poorly workmanlike.

First of all, when we buy doors and windows, the business must go to the owner's house to measure the size, and then place an order in the factory for production, if it is some small factories due to the size or machine cutting is not accurate, there are errors, do not underestimate these small errors, it is likely to be the culprit of water seepage in doors and windows, so when choosing doors and windows, identify big brands can indeed make the entire door and window process more assured, and at the same time, it is recommended to choose the doors and windows of the glue injection process will be more solid and safe.

The drainage design is not well done.

Another reason for rainwater backflow is that the doors and windows did not consider drainage or the drainage design was not done well when they were originally produced, resulting in water seepage problems in doors and windows, especially when the rainwater accumulated in doors and windows during typhoons and rains, it could not be discharged at all, and naturally it could only seep into the room, resulting in water leakage.

Failed installation.

There is no problem with the quality of doors and windows, so if there is still a water leakage problem, it is the installation of the question of Bu Kai, under normal circumstances, there will be no problems such as water seepage and other problems in the installation of no problem, so no matter at any time the installation of doors and windows needs to be carefully accepted, and timely feedback is found when the problem is found.
