Leak Detection Streatham
Hidden water leaks in Streatham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Streatham buildings.
Local knowledge
Streatham housing, from a leak engineer's side
Streatham offers a mix of inter-war semi-detached homes, larger Victorian villas, and numerous post-war apartment blocks. The semi-detached properties often have shared drainage runs and original iron supply pipes. Apartment blocks have central boiler systems and long, inaccessible pipe ducts. This combination presents issues from ageing metallic pipes in smaller homes and systemic leaks in larger blocks.
Engineer's note
Streatham's mix requires a dual approach: acoustics for pressurised system leaks in houses, and thermal imaging for systemic issues in apartment blocks.
Covered in Streatham
- 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 Streatham
01
Inter-War Iron Pipe Corrosion
Original iron supply pipes in inter-war homes corrode from the inside, causing pinhole leaks that can spray inside cavities. Acoustic amplification is highly effective at detecting the high-frequency hiss of these pressurised leaks through plaster and brick.
02
Apartment Block Duct Leaks
Service ducts in apartment blocks contain heating and hot water risers. Leaks within these sealed ducts cascade down multiple floors. Thermal imaging of duct external surfaces identifies temperature anomalies, guiding a targeted access point.
03
Shared Semi-Detached Drainage
Semi-detached pairs often share a single drainage run to the sewer. A collapse or blockage on one property affects the other. Tracer gas introduced into the drainage system on one side can detect breaches at the boundary.
04
Leaking Header Tanks in Villas
Large Victorian villas may retain old cold-water header tanks in lofts. Tank failures or corroded feed pipes cause water to pour through ceiling roses and light fittings. Moisture mapping of ceilings below identifies the epicentre of saturation for accurate source identification.
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 Streatham — FAQs
How quickly can you attend a leak in Streatham?
Same-day appointments are usually available in Streatham and across Lambeth, 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 Streatham?
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 Streatham properties?
Yes — Streatham offers a mix of inter-war semi-detached homes, larger Victorian villas, and numerous post-war apartment blocks. The semi-detached properties often have shared drainage runs and original iron supply pipes. Apartment blocks have central boiler systems and long, inaccessible pipe ducts. This combination presents issues from ageing metallic pipes in smaller homes and systemic leaks in larger blocks.
Can you provide a report for my insurer?
Every Streatham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
