Is the window leaking a property problem or is it repaired by yourself-

First of all, we must find out the reason why the window leaks. If it is due to improper property management, the property company will contact the construction and maintenance unit for maintenance. If the window leaks because of the quality of the house, the owner can ask the property management company to contact professional maintenance personnel for maintenance, but he needs to bear the maintenance costs himself. In addition, if the house is still under warranty, you can find a developer to repair it.

1. What are the common causes of water leakage in windows?

1. Unqualified window profiles: the temperature difference between the window frame and window sash is serious, the product is irregular, the strength is insufficient, the diagonal tolerance is large, and the gap with the hole is too large, which is easy to cause leakage.

2. Unreasonable drainage design: the outer window sill is higher than the inner window sill; No outward drainage slope with a slope of not less than 3% shall be made on the windowsill surface protruding from the wall; The lower part does not drip.

3. There is no waterproof and sealing treatment around the outer window frame.

4, sealant, sealing strip quality is poor, under the action of temperature difference, premature deformation failure, which can't prevent rainwater infiltration, leading to leakage.

Second, how to prevent the window from leaking?

1. Check the hole size before installing the window. The reserved hole position of the window should be correct, and the gap between the frame and the wall should be even, controlled at 20 ~ 30 mm, and the deviation is too large, so it should be treated with fine stone concrete first.

2, outside the window should do a good job of dripping, windowsill should do a good job of soaking, the inner windowsill should be higher than the outer windowsill.

3, window frame joints should be carefully checked. See whether the joint shape and size meet the sealing design requirements, and first deal with the joint defects and cracks to be sealed.

4. Joint surface treatment. Rinse the seam between the window frame and the wall with clear water, so as to be dust-free, sand-free, pollution-free and sundries-free.

5, the gap between the window frame and the wall should be filled with foam sealant.

6, sealant embedded fill dense. After 60 minutes of filling construction with foam caulking agent, cut it with a knife, leave a notch 6mm deep in the gap around the frame, and then fill it with sealant. When filling sealant, the operation should be smooth, and the gun nozzle should always aim at the bottom of the joint with an inclination angle of 45. Always keep the extruded sealant at the front end of the gun nozzle when moving; There is squeezing pressure in the seam, so don't drag the glue away. Avoid leakage or holes; Rubber strip should be straight, streamlined and tidy, with a smooth and beautiful surface.

7, pay attention to open the drain pipe. The lower sill of the window frame should be provided with drainage holes, the position and number of which should ensure smooth drainage and no water accumulation in rainy days.

8. Spraying waterproof agent for external wall. For the exterior wall facing within 30cm around the window sill of the outer window cover and the exterior wall facing within 30cm on the vertical side of the outer window cover, a colorless, transparent and efficient exterior wall waterproofing agent is sprayed for seepage prevention.

9. After the sash is installed, cooperate with the external wall to carry out water spraying test to test the waterproof performance of the window.
