Leak Detection Catford
Hidden water leaks in Catford pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Catford buildings.
Local knowledge
Catford housing, from a leak engineer's side
Catford is characterised by long rows of Victorian and Edwardian terraces, many with distinctive two-storey rear extensions housing kitchens and bathrooms. These extensions often have shallow roof spaces where plumbing is exposed to temperature extremes. The soil in parts of Catford can be clay-heavy, leading to ground movement that stresses the concentrated pipework in these rear structures, making joints prone to failure.
Engineer's note
Ground movement and exposed pipes mean leaks can start suddenly. Our engineers are on call around the clock to diagnose and stop them.
Covered in Catford
- Hidden leaks under floors and in walls
- Underground supply pipe leaks

What fails here
Common leak problems in Catford
01
Leaks from Exposed Pipework in Shallow Roofs
Pipework running through the shallow roof space of a back addition is vulnerable. A burst from freezing or a pinhole leak from corrosion can quickly soak insulation and ceiling plaster. Staining or sagging on a kitchen ceiling is a direct call to action.
02
Failed Joints Due to Ground Movement
Clay soil movement can subtly shift the foundations of back additions, stressing pipe joints where rigid old iron meets more modern copper or plastic. This leads to slow, persistent leaks that erode mortar and cause damp at the junction of the extension and main house.
03
Leaking Drain Runs Under Extensions
Original ground-level drain runs were often built over when the rear extension was added. A fracture in this buried drain under the kitchen floor causes persistent damp smells and wet patches. Our electronic leak detection can locate this without unnecessary digging.
04
Faulty DIY Plumbing in Extended Kitchens
Kitchen modernisations in these extensions sometimes involve non-compliant DIY plumbing. Poorly soldered joints or incorrect waste connections behind new units fail, leaking into cabinetry and subfloors. A warped plinth or soft cabinet base is an urgent sign.
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 Catford — FAQs
How quickly can you attend a leak in Catford?
Same-day appointments are usually available in Catford and across Lewisham, 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 Catford?
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 Catford properties?
Yes — Catford is characterised by long rows of Victorian and Edwardian terraces, many with distinctive two-storey rear extensions housing kitchens and bathrooms. These extensions often have shallow roof spaces where plumbing is exposed to temperature extremes. The soil in parts of Catford can be clay-heavy, leading to ground movement that stresses the concentrated pipework in these rear structures, making joints prone to failure.
Can you provide a report for my insurer?
Every Catford detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
