Leak Detection Hendon
Hidden water leaks in Hendon pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Hendon buildings.
Local knowledge
Hendon housing, from a leak engineer's side
Hendon presents a mix of large Edwardian terraces and substantial 1930s semis, many with original internal plumbing layouts. Loft conversions are prevalent, adding bathroom pressure on older vertical pipe runs. The area has a high proportion of properties with suspended timber floors, where leaks can travel far from the source. Original cast iron waste pipes are still in operation here, prone to rust-through from the inside. This environment requires tracing leaks that disperse widely under floorboards.
Engineer's note
If water appears at a skirting board, the leak is likely under the floor. Isolate the water and call—our engineers are equipped for under-floor leak tracing in these properties.
Covered in Hendon
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Hendon
01
Loft Conversion Pipe Stress
Adding an en-suite in a loft conversion strains the existing hot and cold water rises. New tees into old vertical pipes can crack from vibration, leaking inside walls. Water often appears in downstairs ceilings days later. We ascend to the loft to inspect the new connections first.
02
Cast Iron Waste Pipe Failure
Original cast iron soil and waste pipes corrode from the inside, leading to slow leaks at joints or rust holes. The leak is often intermittent, flowing only when wastewater passes. Stains on external walls or damp in ground floor areas are typical signs. We camera-survey the stack to locate the degradation.
03
Suspended Floor Leak Spread
With widespread suspended timber floors, a leak from a central joint can run along joists and appear at the skirting board far away. The source is rarely directly below the damp patch. Our moisture mapping follows the trail back to the origin under the floor.
04
Original Bib Tap Leaks
Many properties retain original bib taps (wall-mounted outdoor taps) on brickwork. The gland packing deteriorates, causing a constant drip that soaks the wall and foundations. The leak is often mistaken for rising damp. We replace or repack these period fittings to stop the saturation.
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 Hendon — FAQs
How quickly can you attend a leak in Hendon?
Same-day appointments are usually available in Hendon and across Barnet, 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 Hendon?
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 Hendon properties?
Yes — Hendon presents a mix of large Edwardian terraces and substantial 1930s semis, many with original internal plumbing layouts. Loft conversions are prevalent, adding bathroom pressure on older vertical pipe runs. The area has a high proportion of properties with suspended timber floors, where leaks can travel far from the source. Original cast iron waste pipes are still in operation here, prone to rust-through from the inside. This environment requires tracing leaks that disperse widely under floorboards.
Can you provide a report for my insurer?
Every Hendon detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
