Local knowledge
How Islington properties leak
Islington housing is dominated by Georgian and Victorian terraces with basement conversions. Basement conversions sit below the water table line of old clay drains and mains; distinguishing a pipe leak from penetrating damp is step one.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Islington
- 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
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.
Common leak problems in Islington
Basement Pipe Leaks vs Damp
In Islington's Georgian and Victorian terraces, basement conversions are common. These spaces sit below the water table, adjacent to old clay drains and mains. The first critical step we take is to determine whether you have an active pipe leak or penetrating damp, as the solutions are completely different. We deploy specialist equipment to pinpoint the moisture source immediately.
Failing Clay Drainage Lines
The original drainage for many Islington properties consists of ageing clay pipes. These can crack, settle, or become blocked by tree roots, leading to slow drainage or backups. A leak from a cracked clay drain running below your basement can easily be mistaken for a general damp issue. Our engineers use CCTV surveys to inspect these lines without destructive digging.
Leaks in Concealed Period Pipework
Behind the original lathe and plaster or within floor voids of these older homes, original lead or iron pipework may still be in use. A pinhole leak in these concealed lines can cause significant, hidden water damage over time. We use acoustic and thermal imaging to trace the exact path of the leak through walls and floors, minimising disruption to your period features.
Mains Water Supply Line Breaches
The incoming mains water feed to your property, often an old lead or iron pipe, runs through the ground. In basements below the water table, pressure from surrounding groundwater can force water through even a small breach in this pipe, creating a constant ingress. Isolating and testing the mains supply is a standard first check for unexplained basement water.

How to Choose a Leak Detection Company in London: Speed is Everything
Choosing a leak detection company in London comes down to one critical factor: response speed. Here’s how to ensure you get immediate, 24/7 action.
Leak detection in Islington — FAQs
How quickly can you attend a leak in Islington?
Same-day appointments are usually available in Islington, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Islington is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Islington detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Islington do you cover?
All of it — including Islington, Highbury, Holloway, Angel, Archway. We cover every London borough, so coverage never depends on which side of a postcode line you live.
My Islington basement conversion is damp. Is it a leak or rising ground moisture?
It can be either, and the two are often confused. Basements below the water table can draw moisture through walls and floors without any pipe failing. Moisture mapping, thermal imaging and meter readings help separate a live leak from ground damp or a tanking failure, so you know whether a plumber, a damp specialist or a waterproofing contractor is the right next step before any work.
In an Islington flat conversion, who pays if the leak is in a shared supply?
It depends on where the fault sits and your lease. Leaks in a private section within your demise are usually yours; those in communal pipework or another flat may fall to the freeholder or that leaseholder. Non-destructive tracing first pinpoints the exact source, which gives you clear evidence to share with the managing agent, freeholder or neighbour before responsibility and costs are agreed.
