Read beyond the shape of the patch
The rooms above, the opposite face of the wall and nearby fittings may all be relevant. Comparing moisture patterns with the layout and appropriate pipe checks helps distinguish a suspected leak from other causes. The proposed opening follows the evidence rather than simply the darkest mark.
When this investigation may help
- Blistered paint along a pipe route
- Damp on both sides of an internal wall
- Soft plaster near a bathroom
- A stain returning after decoration
A method suited to the evidence
Comparing damp patterns across the affected area. Meter readings can be influenced by the material and other factors. Damp does not by itself establish a leaking pipe.
Depending on the property, other appropriate methods may complement the investigation. Read about moisture mapping or compare the methods.
