Start with the right question
What causes a recurring damp patch?
Timing, location and weather patterns can help distinguish plumbing leaks from other moisture sources
Leak investigation →What is a heat-loss survey?
A room-by-room calculation estimates the heat each space loses under defined conditions

Useful starting points based on the checks M&W makes in Jersey properties
What should I record before reporting a possible leak?
Note when the mark first appeared, whether it changes after rain or water use, which rooms or fittings are nearby and whether the water meter moves when outlets are off Photographs taken over several days can also help show a pattern
When is a heat-loss calculation useful?
It is valuable before a heat pump, boiler replacement, radiator upgrade or underfloor-heating design The calculation shows room demand so equipment and emitters can be selected from property data
What makes a useful project enquiry?
Include the property address, a clear description of the work, photographs of the area and any plans or supporting files M&W uses TradeHQ to collect these details before arranging the next step
