Even though the doors and windows are tightly closed, water keeps seeping into the house on rainy days. In rainy weather, it is even more likely to mold the curtains and crack the floor.

Not only old residential areas, but also some new ones, even with new windows, still leak water. What is the reason for this? Today, the editor will analyze and analyze the issues of window leakage for you!

Firstly, why do windows leak water?

1: Window aging caused by time and environment. Vibration occurs when closing doors and windows, and as the usage time increases, the gap between the window and the wall becomes larger, leading to water leakage. If the quality of the window is poor and the material strength of the window frame is not up to standard, it will deform over time, and even the mortar layer at the edge of the window frame may crack or fall off. In this case, leakage problems are more likely to occur.

2: Construction issues. Failure to follow the standard requirements during window installation can easily lead to water seepage, such as inadequate sealing treatment with flexible materials or waterproof mortar filling the lower part of the window frame; The outer window sill has not been constructed with flashing, and the upper window edge has not been treated with eagle beak.

3: The drainage hole is not smooth. Sliding windows are prone to rainwater accumulation in the sliding frame groove on rainy days, which can be discharged through the drainage holes. If the construction of the outer window sill is not careful, it is easy to seal the drainage outlet. Over time, debris accumulates in the frame groove, which cannot be discharged and can block the drainage holes. Rainwater is difficult to drain and will seep inward into the wall.

4: The sealing strip is aging. Sealing strips play an important role in waterproofing, sealing, and energy saving in plastic steel doors and windows, bridge cut aluminum doors and windows, as well as wooden doors and windows. They provide sound insulation, dust prevention, frost resistance, and warmth retention. It must have strong tensile strength, good elasticity, as well as relatively good temperature resistance and aging resistance. Poor quality sealing strips age quickly and lose their elasticity, making them unable to provide waterproof sealing. Some may even cause glass to loosen.

What measures can be taken for windows that have already experienced leakage problems?

1: Check the drainage holes. If the window is sealed and does not leak air but only leaks water, you can first check if the drainage hole is blocked. If it is a blockage problem, you can clean it up; If it is a problem with the location of the drainage hole, it is necessary to close the original drainage hole and open a suitable location.

2: Check the window material. If the water leakage problem is caused by poor window quality, it needs to be repaired and replaced as soon as possible. In severe cases, the window can be directly replaced to prevent greater safety accidents caused by inferior window forms. If only the sealing strip is aging, simply replace the sealing strip.

3: Re seal the gap. If the gap between the window and the wall is too large, causing water and air leakage problems, the window needs to be resealed. If it is the gap between the wall and the window sill, the original sealing material needs to be removed and filled with weather resistant glass adhesive for sealing; For the gaps in the windowsill, the original sealing material needs to be removed, sealed with weather resistant glass glue, and then sealed with cement mortar and treated with waterproofing.

Windows are meant to accompany our homes and live with us for decades. In order to have a comfortable life in the future, it is still necessary to choose high-quality and durable ones, especially those small details that affect usage, which need to be taken seriously. If you compromise for a long time and end up with a long period of frustrating life, it is not worth it!
