Leak Detection Welling
Hidden water leaks in Welling pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Welling buildings.
Local knowledge
Welling housing, from a leak engineer's side
Welling is characterised by rows of interwar semis and terraces, many with modest rear extensions. The compact layout means plumbing is often condensed, with bathroom stacks internalised. Suspended timber floors are standard, and properties frequently have combi boilers retrofitted to old pipework. The density means a neighbour's leak can sometimes affect adjoining properties, complicating diagnosis.
Engineer's note
Speed is critical in Welling's tightly-packed homes. We dispatch engineers immediately to prevent a small leak from damaging multiple properties.
Covered in Welling

What fails here
Common leak problems in Welling
01
Leak Spread in Terraced Rows
In terraced blocks, a leak in one property can travel along continuous joist lines into a neighbour's subfloor space. If you have damp with no obvious source, the fault might originate next door, requiring careful investigation.
02
Retrofitted Combi Boiler Stress
High-pressure combi systems put old pipework and joints under new stress. Weak points in original lead or copper runs under floors can fail, causing sudden high-volume leaks that quickly spread along joist channels.
03
Internal Soil Stack Leaks
To maximise space, soil pipes are often boxed-in within bathrooms. A leak at a joint inside the boxing can go unnoticed, with water running down inside the wall and emerging as a damp patch in the downstairs hallway ceiling.
04
Shared External Drainage Issues
Blocked or fractured shared underground drains can cause water to back up and saturate the ground under a property's floor void. This mimics a plumbing leak, requiring immediate investigation to prevent foundation damage.
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 Welling — FAQs
How quickly can you attend a leak in Welling?
Same-day appointments are usually available in Welling 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 Welling?
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 Welling properties?
Yes — Welling is characterised by rows of interwar semis and terraces, many with modest rear extensions. The compact layout means plumbing is often condensed, with bathroom stacks internalised. Suspended timber floors are standard, and properties frequently have combi boilers retrofitted to old pipework. The density means a neighbour's leak can sometimes affect adjoining properties, complicating diagnosis.
Can you provide a report for my insurer?
Every Welling detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
