Leak Detection Dulwich
Hidden water leaks in Dulwich pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Dulwich buildings.
Local knowledge
Dulwich housing, from a leak engineer's side
Dulwich is characterised by larger Victorian and Edwardian family homes, often with later extensions and loft conversions. The original plumbing was designed for a single bathroom, and subsequent modifications to add ensuites and wet rooms strain the old waste and vent stacks. Period features like suspended timber floors and void spaces allow leaks to spread unseen. Properties often have long, complex pipe runs from the street to the rear of the house.
Engineer's note
Our detailed reports for Dulwich properties clearly separate 'trace & access' costs for the leak location from the subsequent repair quote, as required for insurer approval on high-value homes.

What fails here
Common leak problems in Dulwich
01
Extension Plumbing Junction Failure
Leaks frequently occur where new bathroom extensions tie into the original home's drainage. We meticulously trace and expose these junctions, providing photographic proof of the failure mode for the adjuster.
02
Suspended Floor Void Concealment
Leaks from central heating pipes or upstairs bathrooms can pour into the extensive void under suspended timber floors for days before signs appear. Our thermal and acoustic detection locates the source without unnecessary floorboard removal, controlling claim costs.
03
Vent Stack Blockage & Backup
Older cast-iron vent stacks serving multiple new bathrooms can become partially blocked, causing slow drainage and sewer gas issues that mimic a leak. We diagnose and clear this, preventing an unnecessary major leak claim.
04
Garden Supply Pipe Leaks
Long runs of iron supply piping to outbuildings or rear kitchens are prone to corrosion. We trace these external leaks specifically, as they often fall under different sections of a buildings insurance policy.
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
