Leak Detection Angel
Hidden water leaks in Angel pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Angel buildings.
Local knowledge
Angel housing, from a leak engineer's side
Angel is characterised by its mix of commercial ground floors and residential upper floors with basements, often in tightly packed Georgian properties. Many basements house boilers, laundry facilities, or are used as rental units. The high footfall and commercial activity above can mask the early signs of a leak, such as the sound of dripping water. Furthermore, multiple property conversions mean plumbing systems have been modified extensively over decades, creating complex networks with vulnerable junctions.
Engineer's note
Leaks affecting separate tenancies or businesses can't wait. Our 24/7 team provides clear evidence of the source to facilitate swift repairs.

What fails here
Common leak problems in Angel
01
Leaks in Commercial/Residential Divides
Where a shop or restaurant occupies the ground floor, a leak from their plumbing or refrigeration condensate line can travel down into the residential basement below. Determining responsibility requires quick, accurate tracing. We test systems separately to identify the source.
02
Boiler Condensate Pipe Leaks
Modern condensing boilers are often located in basements, with plastic condensate drains that can freeze, disconnect, or block. This leads to acidic water leaking directly onto the floor. This is a common and urgent issue we resolve by rerouting or insulating the pipe.
03
Leaks from Multiple Kitchen Extensions
Basement kitchens serving separate flats or Airbnb units mean multiple waste lines and water feeds converge. A leak at a shared junction or from an unused feed can be hard to trace. We systematically isolate each unit's supply to find the active leak.
04
Vibration-Induced Pipe Fractures
Constant vibration from delivery lorries, buses, and nightlife on busy streets can gradually fatigue old pipe connections. This leads to hairline cracks that weep water slowly into surrounding brickwork. We check for this pattern near external walls facing main roads.
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 Angel — FAQs
How quickly can you attend a leak in Angel?
Same-day appointments are usually available in Angel and across Islington, 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 Angel?
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 Angel properties?
Yes — Angel is characterised by its mix of commercial ground floors and residential upper floors with basements, often in tightly packed Georgian properties. Many basements house boilers, laundry facilities, or are used as rental units. The high footfall and commercial activity above can mask the early signs of a leak, such as the sound of dripping water. Furthermore, multiple property conversions mean plumbing systems have been modified extensively over decades, creating complex networks with vulnerable junctions.
Can you provide a report for my insurer?
Every Angel detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
