What's with the water seepage in doors and windows?

In spring, the weather is humid, the rain is constant, and the air humidity becomes high. If aluminum alloy doors and windows are not well maintained and cleaned, it is very easy to produce bad changes, which will affect the service life of doors and windows, and will also cause deformation and water seepage of doors and windows. Old carpenter Luban doors and windows talk about the causes and solutions of water leakage in doors and windows!

Unqualified materials and accessories:

The material of the lower frame is too small to be raised as required, and some even bury the window frame in the plastering layer of the window sill, so that rainwater can easily penetrate into the room.

The section size is small, the material is too thin, the seam plane is spliced, and the gap at the flat-fell seam is too large. In order to reduce the cost, the selected profiles are shoddy. Some doors and windows will shake when they are opened, which will lead to cracks between the door frame and the wall, which will not only easily cause leakage, but also affect its use function.

Quality requirements cannot be met during installation:

There is no drip line or eagle mouth on the upper part of the window, and the slope of the windowsill is too small or there is no dripping eaves, which makes the rain slowly leak into the room along the wall when it rains.

Too thick sealant blocked the drain hole, and the height of the windowsill caused the rainwater in the push-pull slot of the lower frame of the window to be drained in time, which led to rainwater infiltration into the room.

The joint with the hole wall is not sealed enough;

The rubber sealing strip and water blocking brush strip for installing glass are not in place or fall off.

Poor construction of external wall glass glue leads to water seepage at flat-fell seam.

The gap between the door and window frame and the wall is not sealed with sealant or the process is rough, and the dust on the surface of the notch between the frame material and the corner is not cleaned before gluing, which is the weak link of waterproof.

Solutions to water seepage in doors and windows;

Check whether the external wall glass glue is well constructed. Sometimes a small hole can cause rain to seep into the home.

In case of window frame, wall and window sill leakage, the original sealing strip shall be removed and sealed with weather-resistant glass glue. The gap between the window frame and the outer windowsill shall be sealed with weather-resistant glass glue, and then sealed with mud mortar for waterproofing.

The water leakage caused by the blockage of the window frame drainage groove can be solved by keeping the drainage groove unobstructed. If there is a problem with the position of the drainage hole, it is necessary to close the original hole and re-open it.

The window is installed on the dripping eaves. Don't install too many windows to expand the indoor space. Without dripping eaves, the chances of water leakage in windows will increase. If there is no dripping eaves in the original house, you can simply dig one out or add a layer of iron on the window eaves.

For doors and windows that have been installed for more than a few years, it is necessary to maintain the glass glue on the external wall and check whether the glass glue is cracked, so as to repair the cracks in time.
