Should the windows of residential buildings be repaired for water leakage?

Leaky windows in residential buildings should be maintained, not maintained. If the windows of residential buildings are within the warranty period, the property company shall contact the construction and maintenance unit for maintenance. After the warranty period expires, you can ask the property company to repair or ask the property company to contact professional maintenance personnel for maintenance, but the owner should bear the maintenance costs. In other words, the property management company has no obligation to give you free maintenance, whether within the warranty period or outside the warranty period. The construction unit shall be responsible for the warranty period, and the owner shall pay for it outside the warranty period.

What if the balcony window leaks?

1, check the joint between the window and the wall, remove the original aging or damaged sealing material, and then clean up the base to be smooth and straight. The large gap between the window and the wall is filled with styrofoam, and the inside and outside, as well as the window frame and sash molding, must be sealed with styrofoam.

2. For the balcony with serious leakage, waterproof should be redone, especially the top surface and wall surface. You can also add a water baffle above the wall to reduce the influence of rain on the filling layer between the window walls. Good sealing materials should be selected during maintenance, and the leakage point should be carefully blocked.

3. For the owner who is renovating, it is suggested that in order to avoid this situation, try to choose aluminum alloy windows with strong anti-aging ability of sealing strips, and there is no obvious gap in the splicing process.

What is the reason for the leakage of aluminum alloy window?

1. Water leakage caused by irregular manufacturing of windows: there may be no drainage holes in windows, especially sliding windows, so the rainwater can't be completely discharged in the sliding frame groove, and then it will seep into the house when it is full, or the drainage holes are not blocked when the outer window sill is tiled, and all the rainwater in the sliding frame groove will seep into the wall, causing water leakage.

Windows should use a special sealing strip with good elasticity and standard thickness, which matches the profile to ensure that the glass beads are pressed seamlessly. The sealing strip must be a whole piece, and the interface must be selected at the upper part of the window and connected with glue. Good sealing strips have the taste of natural rubber, while inferior ones are hard, easy to crack and pungent.

2. The irregular installation of the window causes water leakage: the lower frame of the window connects the window with the wall, and the head of the explosion screw in the window frame should be sealed with sealant, so that the water in the window frame will not penetrate into the wall along the explosion screw, but will be discharged along the drainage hole. This water leakage phenomenon is quite secretive. Everyone always focuses on whether there is a problem with the waterproof of the gap between the wall and the window, and it still leaks after repeated repairs, so this problem deserves the attention of the installers in the door and window industry.

Now many windows are corner windows, and there are many splicing places. These places should be sealed with sealant. If it is not sealed, it will become a hidden danger of water leakage, so the phenomenon of water leakage is quite secret.

3. The gap between the window and the window sill of the external wall is not tightly sealed, resulting in water leakage: after the gap between the wall and the window is filled with foaming agent, the gap between the window and the wall must be sealed with waterproof sealant, provided that the gap is not too large. If the gap is too big, it must be filled with waterproof mortar first. After the doors and windows are installed and fixed, foaming agent should be filled in the windows. After curing, cut them flat and seal the inside and outside of the rear frame with sealant. This is a very meticulous manual work. Clean the wall with a clean brush first, then apply waterproof sealant and smooth it with soapy water. This treatment is not only beautiful and smooth, but also fills the capillary cracks between the wall and the window. But pay special attention, the wall must be dry.

4. The installer is unprofessional and doesn't know how to install the original aluminum alloy window, resulting in water leakage on the wall. Old houses are used to using old aluminum alloy doors and windows. When they are installed, they are all connected to the wall with fixing pieces, and then filled with waterproof mortar, so the fixing pieces are buried in the wall at least one centimeter, and the fixing pieces are still relatively long. The correct way is to cut off the connection part between the fixing piece and the wall first, and then remove the window. If the fasteners are forcibly removed, the waterproof mortar on the window sill of the external wall will collapse together with the mosaic, destroying the original waterproof. If it is not repaired in time, the plastic steel window may leak after installation.
