Leak Detection Crayford
Hidden water leaks in Crayford pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Crayford buildings.
Local knowledge
Crayford housing, from a leak engineer's side
Crayford offers a blend of interwar semis, post-war estates, and some newer infill developments. The older housing stock strongly exhibits the borough's classic suspended timber floor construction. Many homes have seen incremental upgrades, leading to complex plumbing hybrids. Proximity to the river Cray means some areas have high water tables, which can exacerbate leak damage and complicate detection.

What fails here
Common leak problems in Crayford
01
Leak Amplification in High Water Table
A small leak under the floor in areas near the river can saturate the subfloor void more quickly, leading to rapid wood rot and damp smells. The high ground moisture can also make pinpointing the active leak source more challenging without professional equipment.
02
Faulty Overflow from Old Cisterns
Many homes still have older WC cisterns with plastic overflows that discharge directly into the soil stack. If this connection fails internally, water runs down the outside of the stack inside the wall, appearing as a mystery damp patch on the ground floor.
03
Leaks from Abandoned Pipework
When systems were updated, old lead or iron pipes were often just left in place under floors. These dead legs can still hold water and corrode, eventually leaking and contaminating the subfloor space without being connected to any active appliance.
04
Sink Waste Leaks Under Kitchen Extensions
Single-storey kitchen extensions on these semis often have waste pipes laid in a shallow trench beneath the new concrete slab. Ground movement can fracture these pipes, causing leaks that wash away sub-base and threaten the extension's stability.
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 Crayford — FAQs
How quickly can you attend a leak in Crayford?
Same-day appointments are usually available in Crayford and across Bexley, 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 Crayford?
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 Crayford properties?
Yes — Crayford offers a blend of interwar semis, post-war estates, and some newer infill developments. The older housing stock strongly exhibits the borough's classic suspended timber floor construction. Many homes have seen incremental upgrades, leading to complex plumbing hybrids. Proximity to the river Cray means some areas have high water tables, which can exacerbate leak damage and complicate detection.
Can you provide a report for my insurer?
Every Crayford detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
