Are you still looking for property repair when your balcony leaks?

The balcony leakage needs to be analyzed according to two situations. One is still under warranty. In this case, we can be directly responsible for the maintenance by the developer. Generally speaking, the maintenance period is 5 years. The other is that the balcony leaks after the warranty period, and you can find a property company to be responsible for maintenance, but it is a paid service. If the problem is not particularly serious, please call the property management company directly, and the property management company can also invite professionals to come to the house for maintenance.

What are the causes of balcony leakage?

1. aluminum alloy window reason: the waterproof sealing layer of aluminum alloy window is not enough, and the sealant will crack when it ages and hardens. The most serious thing is that there is no drainage channel in the structural cavity of aluminum alloy window. The rainwater entering the cavity of aluminum alloy window structure under the action of indoor and outdoor wind pressure difference is not discharged in time by the drainage system, resulting in water pressure and leakage along the wall.

2. Construction reason of window wall: the joint between aluminum alloy window and wall is prone to water leakage. If the materials are not filled as required, such as the label of waterproof cement mortar is incorrect, there is a gap between the window frame and the wall when filling, especially for doors and windows with corners or connected forms, and the corresponding connecting rods are not strictly sealed, which will cause rainwater leakage.

3. Reasons for waterproof construction: The outdoor balcony has low waterproof requirements, and generally only simple waterproof measures are taken. However, if you change the balcony into a closed room, if you put the washing machine on the balcony upstairs, and you don't take the necessary waterproof measures or just take simple waterproof measures, it will easily cause the balcony to leak.

What are the specific practices of balcony leakage treatment?

1, the balcony leaks first, mainly from the top to the bottom of the roof, because water flows to the bottom. See if there are cracks in the roof, whether the original waterproof layer has aged and fallen off, and whether there are bubbles in the original waterproof coiled material on the roof. If there are bubbles, it proves that water has entered the bottom of the waterproof layer, so it leaks. There is also whether the eaves gutter on the roof is blocked. In rural areas, there are still a large number of tile houses. When the roof leaks due to broken tiles, just replace the tiles. This step is also called "leakage".

2. If the roof is not waterproof, just remove the leaking part 2~3cm deep, clean it and water it with asphalt. Now there is a finished asphalt coating. It hardly leaks on sunny days. If there is a waterproof layer, it will be more troublesome. Need to remove the surrounding waterproof, waterproof again. When doing this, pay attention to the strengthening layer at the joint with the original waterproof.
