Is the house leaking property management or self-repair?

1. If it is still under warranty, you can contact the developer directly, and the developer will be responsible for the maintenance. If it is because the house leaks rain, resulting in damage to furniture, household appliances, floors, etc. in the house, the responsibility can also be borne by the developer.

2. If the warranty period expires, that is to say, water leakage occurred five years ago, the specific responsibilities should be divided. If it is caused by human factors, it should be repaired by itself. For example, changing pipes at will, leading to the problem of anti-water at home, will bear a relatively large loss.

What causes the house to leak?

1, the weather when painting is also the main reason for water leakage. Frost days, windy days, high temperature days above 35 degrees Celsius, or low temperature weather below 10, the effect of painting exterior walls is generally not good.

2, the wall cavity is not filled, and the cement shrinks and cracks after painting.

3. The main reason for the leakage of exterior wall tiles is that the cracks of tiles are prone to water leakage after the tiles are stuck at the joints caused by primer coating, pores, cracks and changes in the base.

4. Cast-in-situ casting is not a one-time molding, but is completed in two or more times.

5. Water is applied too fast, too little and too much, the interval between water application and painting construction is not well grasped, and protection is not done after painting.

6, improper operation in painting construction, upper and lower interface pulverization, water infiltration into the wall, or cut corners without brushing twice, beam mouth uneven with a disposable brush.

7. Improper proportion of cement, sand and water, too much water reduces the cement grade, the sand is not clean, the wall is not firmly bonded, too much yellow sand causes the wall to be loose, the cement concentration is too high or the grade is too high or the sand is too fine, which causes the wall to crack, or it feels bad after mixing. These problems occur when raw water and ash are added.

8. Inappropriate cement is used, so pozzolanic portland cement, slag portland cement and fly ash portland cement cannot be used for external walls, and ordinary portland cement can only be used. The greater the shrinkage of cement, the more serious the water leakage.

9. The exterior wall is painted too thin or only one layer is painted, and a few sand grains are too large, resulting in pores and cracks. The joints should be movable due to changes in the size of the grassroots.
