Leak detection in London.

Period conversions, mansion blocks, basement flats and flat roofs, London leaks are rarely simple, and the disruption of finding them is rarely welcome. We pinpoint the source without tearing the place up, and report it the way managing agents and insurers need.

Surveying across the capital
01 — Available across London

The full service, across the city.

Whether it’s one flat with a damp ceiling or a managed block with a recurring escape of water, the work is the same: locate it precisely, prove it, and report it clearly.

02 — Managed property & claims

Built for London's managed property.

A leak in a block doesn’t stay in one flat, it becomes a claim, a dispute between leaseholders, and a job for whoever manages the building. We make that part straightforward.

Managing agents

Blocks & multi-unit

Where the leak crosses flats and the cause is disputed, we identify the source and the responsible demise, clearly, so the right party pays.

  • Source and demise identified
  • Minimal disruption to occupied flats
