Hello. Moisture on the walls in the bathroom may appear due to poor ventilation or poor sealing. If your bathroom does not have a window or a good exhaust system, then moisture can accumulate on the walls and ceiling. Also, if you have poorly sealed doors and windows in the bathroom, then this can lead to these hedgehogs. But if the question is in the leak, then you will need the Commercial Plumbing Service. Because you need to diagnose the problem and eliminate it using special tools. But this does not take much time when specialists are qualified.
