Ceiling stain under a chalet bungalow's loft shower room
The property
A chalet bungalow with its loft turned into a bedroom and shower room. Its pipes cross behind the eaves, then drop down a stud wall beside the living room.
The problem
A brown patch on the living room ceiling kept growing, even on days nobody showered. A plumber had resealed the tray, and the patch still spread.
How we found it
Moisture readings put the wettest point under the stud wall, away from the tray. With the hot pipe isolated, its gauge fell, and a thermal camera with a hot tap running showed warmth spreading from one joint.
The outcome
A small panel was cut at the mark and the joint remade, quoted separately. The tiles stayed on, and our report went with the ceiling claim.
