Damp ring on a flat's hall ceiling
The property
A ground floor flat in a two-storey block from the town's post-war growth, with concrete between the floors and the flat above let privately.
The problem
A damp ring kept widening on the hall ceiling. Upstairs, the tenant saw nothing amiss, though their boiler needed topping up every few days.
How we found it
Moisture readings below peaked under the upstairs hall. Up there, a thermal image taken with hot radiators showed heat seeping out around a pipe in the floor; a pressure test agreed.
The outcome
Marked upstairs and photographed, the spot went in a report that both households received. Fixing the pipe through a small section of floor was quoted separately.
