Leak Detection Purley
Hidden water leaks in Purley pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Purley buildings.
Local knowledge
Purley housing, from a leak engineer's side
Purley is characterised by spacious 1930s semi-detached homes and later suburban developments, with some larger detached properties. Properties here often have extensive ground-floor footprints, longer pipe runs from the street, and original outbuildings with later plumbing additions. The combination of ageing original systems and piecemeal extensions creates complex pressure zones and hidden leak paths our engineers are trained to trace.
Engineer's note
Our documentation clearly separates damage caused by a sudden plumbing leak from pre-existing settlement issues, a key distinction for Purley property claims.
Covered in Purley
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss

- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
What fails here
Common leak problems in Purley
01
Leaks in Extended Pipe Runs to Outbuildings
Many properties have garages, workshops, or annexes supplied by long, often poorly insulated pipe runs. These are susceptible to ground movement and frost damage. We trace these dedicated lines to confirm the leak location is on the property supply, not the main, which is essential for insurer approval of excavation and repair.
02
Differential Settlement Causing Joint Failure
The varied substrate in Purley can lead to differential settlement between house and extension. This stresses pipe joints running across the movement gap, causing slow leaks. Our reports correlate leak evidence with structural movement, helping insurers understand this is a plumbing failure due to a covered peril, not a general maintenance issue.
03
Corrosion in Original Iron Mains
Many 1930s homes still have the original iron communication pipe from the boundary stop tap to the house. Internal corrosion leads to reduced flow and pin-hole leaks. We provide video inspection evidence of pipe condition, which satisfies insurer requirements for funding a full lead-in replacement.
04
Garden Irrigation System Leaks
Buried garden irrigation systems, common in Purley, can develop leaks that saturate ground near foundations. We differentiate between irrigation leaks and domestic supply leaks using flow analysis and isolation tests, preventing insurers from paying for unrelated structural repairs.
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 Purley — FAQs
How quickly can you attend a leak in Purley?
Same-day appointments are usually available in Purley and across Croydon, 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 Purley?
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 Purley properties?
Yes — Purley is characterised by spacious 1930s semi-detached homes and later suburban developments, with some larger detached properties. Properties here often have extensive ground-floor footprints, longer pipe runs from the street, and original outbuildings with later plumbing additions. The combination of ageing original systems and piecemeal extensions creates complex pressure zones and hidden leak paths our engineers are trained to trace.
Can you provide a report for my insurer?
Every Purley detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
