Ceiling damp under a flat in a Georgian house
The property
A tall Georgian house near the river, divided into two flats, with the upper flat's pipes running under the original floorboards.
The problem
The tenant below found damp spreading across the living room ceiling. Nothing upstairs looked wet, and the landlord could not say whose pipe it was.
How we found it
Moisture readings put the damp under the upstairs kitchen, whose cold supply alone failed a pressure test. The ground microphone on the boards then found the leak.
The outcome
The landlord agreed a repair price, and we renewed the joint under one lifted board during the visit. One photographed report then went to both tenants.
