Follow the signs
A leak appeared after building work
The timing of recent work is useful context, but it does not establish blame. Plans, photos and a description of changed pipework can help guide a factual investigation.
Useful details to share
Share what was changed and any existing contractor findings. The report records observations rather than deciding liability.
From a sign to a reasoned check
The first aim is to understand the conditions behind what you have noticed. Where is it happening, how often does it change, and which water systems could be involved? The answers help us choose tests that address the actual question.
What a visit may involve
The relevant starting point may be Hidden leak detection. We consider accessible fittings, the system arrangement and any previous findings before deciding which specialist methods are useful.
If suitable evidence supports concealed access, we explain the proposed opening and repair. If it does not, the findings and remaining uncertainty should still be clear.
A note on immediate problems
An enquiry draft does not request emergency attendance. If water creates an immediate electrical or structural hazard, keep away and obtain appropriate urgent help. Do not disturb a bulging ceiling or operate unfamiliar equipment.
