Ceiling stain under a Georgian town house landing
The property
A three-storey Georgian town house in the old centre. The hot pipe from a first floor cylinder climbs to a top-floor bathroom, then runs under the landing boards.
The problem
A brown stain spread across a first floor bedroom ceiling. The boiler held pressure, ruling out the heating, and the insurer wanted the cause found before anything was opened.
How we found it
Moisture readings peaked under the landing. With the cylinder's filling valve shut, the meter stopped, which put the leak on the hot side. As the hot taps ran, the camera found a warm bloom around one joint.
The outcome
We lifted two boards over the mark and remade the joint during the visit, on its own quote. The report and photographs went with the claim for the ceiling.
