If the water leaks from upstairs to downstairs, we can't negotiate. Who can we ask for mediation?

If there is water leakage from upstairs to downstairs, you can find property coordination, or ask the quality inspection department of the house to make an appraisal report on the causes of water leakage and how to make up the leakage, and then you can bring a lawsuit to the court according to the report. Solutions to house water leakage:

1, keep the evidence. If the house leaks, first take photos to keep the evidence;

2. Determine the person responsible for the water leakage. The water leakage of the house is related to the building structure, waterproof treatment and drainage system.

After determining the responsible person, the parties may claim compensation from the property, developer or neighbor;

3. Negotiate rights protection and hold evidence to find the responsible person to negotiate. You can ask the other party to restore the original state, or you can ask the other party to compensate for the maintenance;
