Damp, mould and leak detection across London

We cover all 32 London boroughs and the City of London, coming to you wherever the property is. The boroughs below are grouped the way Londoners describe them (central, north, north west, west, south west, south, south east and east) and every borough links to its own page, which in turn lists the towns and neighbourhoods within it that have a page of their own.

London’s housing is more than half flats, split between purpose-built blocks and houses that were divided after they were built. That shapes the work: leaks between flats, responsibility disputes between leaseholders and freeholders, shared risers and roofs, and condensation in homes that are hard to ventilate sit alongside the solid-wall penetrating damp, rising damp and timber decay of the capital’s Victorian and Edwardian terraces.

Housing across Greater London (Census 2021): 3,423,889 households: 45% owner-occupiers, 30% private renters, 23% social renters. Housing stock: purpose-built flats 40%, converted and other flats 14%, terraced 21%, semi-detached 19%, detached 6%.Source: ONS Census 2021, tables TS054 (tenure) and TS044 (accommodation type), via Nomis.

What we do across London

The same methods on every job: measure, trace, prove, then fix. All services →

Leak detection

We locate concealed supply, heating and waste leaks under floors and behind finishes, and mark the exact spot.

Urgent leaks & burst pipes

If water is actively coming in, phone rather than fill in the form; live leaks go to the front of the queue.

Damp & mould surveys

Room-by-room moisture mapping that separates condensation from penetrating and rising damp.

Moisture mapping & thermal imaging

Seeing through the finish: temperature and moisture patterns that reveal what is happening behind plaster and under floors.
