Does the ceiling leak have to be upstairs?

Not necessarily, I did deal with a problem today, which has nothing to do with the upstairs (or can't be solved from the upstairs). Mainly the water pipe problem. >>>More

Downstairs is repairable. In many cases, the upstairs cannot be repaired, and the maintenance from the downstairs on the spot can be done using two maintenance methods: rigid plugging agent and flexible foaming agent. However, it is best to discuss the leakage of the upstairs ceiling with the upstairs neighbor to find out where the water is leaking and find the best solution. >>>More

The leakage on the roof downstairs must be the cause above....There is no water leakage on the top, how can there be water leakage on the ceiling below.

Not necessarily! The leakage of the downstairs bathroom may be due to the fact that the waterproof layer downstairs is not done, and when the water accumulates a lot, it will continue to seep water to the top! Hope it helps!

The downstairs bathroom is leaking, and it should only be topped. >>>More
