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 large Victorian and Edwardian detached/semi-detached houses, many with original outbuildings now converted, and numerous 1930s purpose-built flats. A key feature is the number of properties with original, unmodernised heating systems and long underground supply pipe runs from the road to the house. Many larger plots have separate coach houses or annexes with their own water connections.
Engineer's note
With many properties having long, private supply runs and outbuildings, a leak can be far from the main house. Our 24/7 team brings the equipment to find it fast, day or night.
Covered in Streatham

What fails here
Common leak problems in Streatham
01
Long Underground Supply Pipe Bursts
Detached houses on large plots often have a long, privately-owned lead or iron supply pipe from the road main to the house. A fracture or corrosion hole in this buried section can flood the garden and undermine foundations before being noticed inside. We use tracer equipment to locate the exact burial path and leak point for targeted excavation.
02
Leaks in Converted Outbuildings
Annexes and converted coach houses frequently have their plumbing fed from the main house via shallow, poorly insulated pipes. These are prone to freezing and bursting in winter, with the leak often going unnoticed in the unoccupied annex until it affects the main house's structure. We check these external feeds immediately during cold snaps.
03
1930s Flat Block Waste Pipe Leaks
Purpose-built 1930s flats often have cast iron waste stacks running internally. Corrosion can cause leaks at junctions, which then run down inside the wall cavity, appearing in a lower flat far from the actual source. Our inspection cameras can survey these vertical stacks to find the weak joint.
04
Leaking Header Tanks in Lofts
Many older properties in Streatham still have cold water storage tanks in the loft. A failure of this tank or its connecting pipework can send a continuous flow of water through the house, damaging multiple floors. Isolating the loft supply is a first priority for any unexplained water from ceilings.
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 large Victorian and Edwardian detached/semi-detached houses, many with original outbuildings now converted, and numerous 1930s purpose-built flats. A key feature is the number of properties with original, unmodernised heating systems and long underground supply pipe runs from the road to the house. Many larger plots have separate coach houses or annexes with their own water connections.
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.
