Common causes of a wet ceiling

New, growing or returning? Understand what a stain can—and can’t—tell you.
Rain-linked dampnessWorse when it rains
Look at the timing before assuming the water is coming from a pipe.
Condensation cluesMould in the corners
Cold surfaces and moist air can leave a different pattern of ceiling dampness.
The stain is the end
of the story.

A small fault above. A visible problem below.
A failed pipe joint is one possible source. Water may first escape inside a floor, beyond the room you can see.
When you can’t see the leak
Ceiling leak detection
with ADI.
A hidden leak can sit behind a bathroom, within a floor or along concealed pipework. Covering the stain won’t resolve an ongoing escape of water.
ADI combines observations with appropriate tests to investigate where water is coming from. The approach depends on the property and the suspected source.
How ceiling leak detection worksMap the affected area
Moisture readings and thermal patterns help guide further checks.
Investigate the source
Suitable pressure, tracer gas or visual tests help distinguish possible faults.
Agree the next steps
Discuss findings, any access needed, and what repair or drying work follows.

The stain was below.
The fault was hidden.
In a Warwick property, ADI investigated kitchen ceiling staining and traced the main leak to a condensate pipe elbow. It’s a useful example of why the visible damage alone doesn’t identify the source.
