How do I know if I have a hidden water leak?
Turn every tap and appliance off, then watch the water meter or the pressure gauge on a combi boiler. If either keeps moving, water is escaping somewhere in the system.
Other early signs are a musty smell in a cupboard, a warm patch on a floor above heating pipes, tide marks appearing on a ceiling, or a boiler that needs topping up more than once or twice a year.
We trace leaks with acoustic and thermal methods before lifting anything, which usually means one small area of flooring or plaster comes up instead of a whole room.
