Leak Detection Tooting
Hidden water leaks in Tooting pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Tooting buildings.
Local knowledge
Tooting housing, from a leak engineer's side
Tooting's housing stock is largely late-Victorian and Edwardian terraces with added bathroom extensions at rear, and numerous converted larger houses into flats. This creates complex, multi-occupancy plumbing systems with frequent inadequate upgrades. Sub-floor voids are often shallow and debris-filled.
Engineer's note
In Tooting's converted properties, our systematic use of thermal imaging and tracer gas is designed to diagnose multi-tenant leaks with minimal disruption.
Covered in Tooting
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
What fails here
Common leak problems in Tooting
01
Flat Conversion Stack Leak Escalation
A single leak in a converted house's vertical stack can affect multiple flats. Thermal imaging of the entire stack column through inspection panels identifies temperature anomalies. Tracer gas injected at the top floor is then monitored at each flat's access point to isolate the leak to a specific floor's section.
02
Bathroom Over-Slab Leak Localisation
Leaks from first-floor bathroom extensions often run over the concrete base and down inside cavity walls. Non-invasive moisture mapping of both the bathroom floor and the wall below identifies the primary moisture concentration. Acoustic sensors placed on the wall then pinpoint the active leak within that zone.
03
Shallow Void Waste Pipe Leaks
Waste pipes in shallow, inaccessible sub-floor voids leak into the compacted hardcore. Inspection cameras are used where access exists, but for sealed voids, tracer gas introduced into the waste system is the only reliable method. Gas detectors at air bricks and floor vents indicate the exit point, revealing the leak location.
04
Lead-to-Copper Transition Corrosion
Historic partial repipes leave lead-to-copper junctions, which suffer from electrolytic corrosion. These often leak intermittently. We use thermal imaging while cycling the system hot and cold to stress the joint, making the micro-leak visible as a localised damp spot, confirmed with a borescope inspection.
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 Tooting — FAQs
How quickly can you attend a leak in Tooting?
Same-day appointments are usually available in Tooting and across Wandsworth, 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 Tooting?
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 Tooting properties?
Yes — Tooting's housing stock is largely late-Victorian and Edwardian terraces with added bathroom extensions at rear, and numerous converted larger houses into flats. This creates complex, multi-occupancy plumbing systems with frequent inadequate upgrades. Sub-floor voids are often shallow and debris-filled.
Can you provide a report for my insurer?
Every Tooting detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
