Who will repair the cracks and leaks in the outer wall of the building?

If the house has not been used for 5 years, that is, it is still under the warranty period, and there is water leakage in the external wall or cracks in the roof, there is no need for maintenance by the property owner, because this is the responsibility of the developer. The use of the house exceeds the warranty period, and the property management leads to water leakage, and the property should bear the maintenance responsibility. If it is the water leakage caused by the owner's decoration, it needs to bear the maintenance responsibility.

Is the external wall seepage a property or owner's maintenance?

We can judge which side will repair the water leakage from the specific reasons.

If the house has not been used for 5 years, that is, it is still under the warranty period, and there is water leakage in the external wall or cracks in the roof, there is no need for maintenance by the property owner, because this is the responsibility of the developer. Of course, the water leakage maintenance that developers are responsible for is mainly caused by natural factors and material factors, and it also needs housing quality testing to judge. If it is vandalized, the developer will not be responsible.

If the house is used beyond the warranty period, the leakage of the external wall is caused by poor property management. At this time, because the property is in breach of contract, there is no obligation of supervision and management, so it is necessary to bear the responsibility of maintenance. However, the related maintenance costs are paid from the maintenance fund.

If the owner's improper construction leads to water leakage during decoration, that is, human factors, then this destroyer is needed to bear the maintenance responsibility.

The best way to solve the leakage of cracks in external walls

1. If obvious cracks are found in the external wall, repair materials can be selected to repair the cracks on the wall. First of all, clean up the cracks on the wall, and don't let the surface have floating dust. At the same time, for uneven phenomena, cement mortar can be used to fill them, including cracks, and grouting treatment should also be carried out.

2, wait until the surface is flat, with polymer waterproof material directly brush on the outer wall, especially for weak places, to coat the bottom waterproof material. Then spray a water repellent with a spray, and the water repellent can effectively penetrate into the wall above 1 cm to form a waterproof layer.

3. After the waterproof layer is completely dried, stick external wall bricks or other wall materials on the external wall. However, if you choose tiles, you must choose ones with better waterproof performance, which can effectively repair the problem of cracking and seepage of the external wall without affecting the inner layer.
