The most concentrated rain throughout the year should be typhoon weather, this time the most able to test whether there is leakage of doors and Windows, if the door and window leakage is not treated in time, then it will affect the indoor furniture will be seriously damp furniture, moldy floor, wall peeling, etc., so the door and window leakage must find the cause, may not be due to quality problems, Today Xiaobian on this topic in detail, I hope to help you!

Excessive force during the installation of doors and Windows causes deformation

The loosening or deformation between the window sash and the frame of the door and window can also lead to water leakage and one of the reasons, in addition to the quality of the door and window is not good, in the process of installation of doors and Windows, the construction workers are not careful to install too hard to cause deformation of the profile doors and Windows, resulting in doors and Windows look closed, but in essence there has been deformation for a long time there will be rain leakage and other problems, So this is not a quality problem but an installation problem.

The outer frame of the door and window is not well sealed with the wall

Because the gap between the outside frame of the door and window and the wall need to be filled with waterproof mortar and foaming agent, and it is also necessary to use sealant to seal. If this step leaks, there may be no impact in the early stage, but there will be a series of air leakage and rain leakage problems, especially on rainy days. This problem needs to be filled by construction personnel, otherwise there will be leakage.

The sealant is not installed properly or the door and window drainage holes are blocked

The sealing strip of doors and Windows plays a very important role in the sealing performance of doors and Windows. If the improper operation in the installation process, resulting in the sealing rubber strip is not installed in place, even if closed, there will be gaps in the frame fan, resulting in potential water leaks in the doors and Windows. At the same time, during the installation process, other things accidentally blocked the drainage hole, resulting in the rainwater in the tank can not be discharged in time, which is easy to cause rainwater backpouring.
