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 significant later extensions. These additions create complex plumbing layouts where new systems tie into old. Properties frequently have deep, landscaped gardens where supply lines and drainage runs are buried, making external leaks hard to locate.
Engineer's note
A leak in a Dulwich home can quickly damage period features. Don't wait for the ceiling to fall – call for immediate trace and access. Our engineers are geared to pinpoint the leak with minimal disruption to your home.

What fails here
Common leak problems in Dulwich
01
Extension Plumbing Integration Failures
Kitchen and bathroom extensions add new pipework that connects to original lead or galvanised mains. The differential movement between the old house and new extension stresses these joints, leading to leaks under new concrete slabs or within floor voids.
02
Garden Supply Line Leaks
External taps, outbuildings, and irrigation systems mean water lines run under lawns and patios. A leak here can saturate the ground, undermining foundations or creating sinkholes. The first sign is often a mysteriously high water bill or a soggy patch of garden.
03
Original Tank & Cistern Overflows
Many older homes retain original cold-water tanks in lofts. A faulty ball valve or split tank can cause a continuous, hidden overflow that soaks through ceilings. The leak is often intermittent, coinciding with peak water usage in the house.
04
Parquet & Floorboard Damage from Leaks
Leaks from first-floor bathrooms or under-sink pipework in these homes often go undetected until they damage original wood floors. Water travels along joists, meaning the wet floorboard is often far from the actual pipe failure point.
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.
Leak detection in Dulwich — FAQs
How quickly can you attend a leak in Dulwich?
Same-day appointments are usually available in Dulwich and across Southwark, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in Dulwich?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know Dulwich properties?
Yes — Dulwich is characterised by larger Victorian and Edwardian family homes, often with significant later extensions. These additions create complex plumbing layouts where new systems tie into old. Properties frequently have deep, landscaped gardens where supply lines and drainage runs are buried, making external leaks hard to locate.
Can you provide a report for my insurer?
Every Dulwich detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
