I am noticing some black damp stains at the lower corners of the wall in kitchen, living room, bedroom etc.
These black stains are quite easy to clean though. Are these stains because of moisture in the air OR is it due to some other reason needing damp proof treatment.
Also the laminate flooring in the living room as bulged slightly in some areas.
Is this somehow related to the above as well ?
Any advice will be greatly appreciated.
