Who should deal with the leakage of the external wall of the house? Is the external wall seepage a property or an owner's maintenance? External wall seepage is a headache, many owners can't handle it themselves, and they don't know who to deal with it, so they always seem very passive and helpless. It doesn't matter. The following small series will introduce in detail whether the external wall seepage belongs to property management and how to deal with it.

External wall seepage belongs to property management. If it is caused by poor property management, the property should bear the responsibility. If it is a housing quality problem, the developer should bear the responsibility. For this kind of dispute, it is generally consultation, not negotiation. Need to carry out housing quality appraisal to see if it is a housing quality problem. The hole in the window has a dripping roof. When rebuilding the balcony, some owners moved the windows out and pressed them on the dripping eaves. Rain will enter the gap between the window frame and the wall and flow into the water from the upper part of the window. Solution: Install drip eaves at the entrance of the cave (through connectors or plastic protrusions, etc.). ), let the water drain smoothly.

Does the external wall seepage belong to the property pipeline? If it is within the maintenance period, it is the responsibility of development. Property coordination during maintenance. . Notice. Obligation to inform. If it is outside the maintenance period, the maintenance cost should be drawn from the public maintenance fund. If the public maintenance fund is withdrawn, the property has the right to formulate, examine and approve, report, supervise and inspect.

How to deal with the seepage of external wall window sill is complicated, which may be caused by the seepage of roof or external wall, then along the mortar layer of wall, and then from the window sill. So the solution to the problem is to deal with it from the outside, but unless it is redone from the outside, it is not easy to find the water leakage point. The developer won't do this for you, and it's basically not operable unless the whole upstairs leaks! The rest are processed from the inside, which requires the materials to have good cohesiveness, durability and waterproofness, and the technology should also be considered. Most people can't repair them well!

According to my experience, it may be caused by one of these two problems. 1. Because the window frame gap was not filled with mortar during window construction, water infiltrated from the window frame. You can try to circle the windowsill with glass glue. The window sill pressure plate is more prone to water seepage, so pay more attention; You can also use waterproof transparent paint on the outer wall and brush waterproof around the window sill.

Now almost all the walls are concrete hollow bricks. If the external wall is pasted with small-sized tiles, there are too many gaps and the waterproof treatment is not in place, which is more likely to cause leakage. The general solution is to paint the exterior wall with waterproof paint, but this is a very troublesome thing and it costs a lot of money.
