for sure the permanent solution is hack the upper floor bathroom tiles & redo the waterproofing. any other method like fixing from ur ceiling side won't last long

if I'm not mistaken. nowadays newly developed housing unit got 2yrs warranty. bank will hold certain amount of ur loan (10% if I'm not mistaken). after 2yrs no complaint from u for the house defect not being repaired then bank will release that balance to the developer. my friend said u can inform developer if they didn't fix it properly, u will file a complaint to the bank so that balance will be hold by bank until they fix it. not sure though. maybe /k who expert can give more correct info.
