Am I liable to break my bathroom to repair a leakage in my downstairs neighbour’s ceiling?
So my downstairs neighbour says that a leakage in his ceiling is from our flat’s bathroom. We did the waterproofing in both our bathrooms tiles after this was brought to our attention, even in the dry area, but the leakage has still continued. I definitely want to help my neighbour out but am not sure the plumber is right to insist breaking the tiles of both our bathrooms to find the leakage, and us having to bear the entire expense. Is it possible the leak is from the society’s common plumbing or maybe their own plumbing? Is there a way to check this? I am reluctant to redo both my bathrooms because the interior of the bathroom was really expensive and we probably will not find similar tiles again. Is there a way out? Anyone who has been in a similar situation or is aware of these things any advice would be appreciated!
