Leak detection in Croydon, done right.
Specialist trace and access leak detection across Croydon borough — Central Croydon, South Croydon, Purley, Coulsdon, Thornton Heath and all CR postcodes. Non-invasive methods, fast response, insurance-ready reports.
Why a leak detection specialist — not a plumber?
This is the most common question we get. The answer matters, especially in Croydon where a large proportion of properties are leasehold flats and managed blocks where unnecessary access work can trigger disputes between floors.
A plumber's expertise is in repairs. Without specialist equipment, locating a hidden leak means making educated guesses about where to open up — which can result in multiple access points, additional cost, and unnecessary damage before the source is confirmed.
A leak detection specialist attends with thermal cameras, acoustic probes, moisture meters, and tracer gas. In most cases, they locate the precise source without opening anything. A plumber then makes a single, targeted repair. The combination typically saves time, money, and disruption.

Leak detection services across Croydon
From Victorian terraces in Norbury to purpose-built maisonettes in South Croydon — these are the most common leak types we find across the borough.
Underfloor Leaks
Common in Croydon's Victorian and Edwardian terraces where original pipe runs sit beneath floor screed or quarry tiles. Located with acoustic and thermal methods — no unnecessary lifting.
Leaks Behind Walls
Failed pipework concealed behind plasterboard or tiles — mapped precisely using moisture scanning before access work is carried out, from CR0 terraces to purpose-built CR5 flats.
Ceiling Leak Sourcing
Water appearing through a ceiling is common in Croydon's large stock of purpose-built and converted flats. We trace the path from origin to visible exit point — not just the stain.
Heating System Loss
A central heating system that repeatedly loses pressure usually has a small leak on the circuit. We use pressure testing and tracer gas to locate it precisely across all Croydon property types.
