What's with the water seepage in the newly built house?

The biggest concern of housing is water seepage, so what about the water seepage of the newly built house?

The wall protection layer is not done well.

If the newly built house is not well insulated, in the cold winter, due to the large temperature difference between indoor and outdoor, the wall is cold outside and hot inside to form condensed water, which leads to the wall being damp and seeping, affecting the overall beauty of the wall.

Leakage of embedded water pipes in the wall

If there is water seepage in the area near the toilet, it is likely to be caused by water leakage from the embedded water pipe in the wall. Generally, there is a problem with the embedded water pipe joint, which leads to water infiltration from the partition wall.

No waterproof measures were taken upstairs.

If the upstairs neighbor fails to follow the construction requirements when doing waterproof works, it will lead to water seepage in the downstairs neighbor's house.

Improper construction during painting

If the wall paint is not completely dried in the first time when painting the wall, the wall paint will be brushed in a hurry in the next time, resulting in the accumulation of water vapor inside the wall, resulting in moisture and water seepage in the wall.

What should I do if the house leaks?

If it is caused by the quality problem of the house itself, and it is within the warranty scope promised by the house, this situation may require the developer to bear the maintenance responsibility. If the water leakage is caused by an adjacent house, the upstairs owner shall be responsible for the loss. If it is a top-floor resident, because the roof belongs to all owners, not some owners enjoy it exclusively. Therefore, the roof leakage can be repaired with the maintenance fund.
