Accurate leak detection in Southwark

R.W. Miller Plumbing & Heating provides professional leak detection across Southwark, covering SE1, SE5, SE15, SE16, SE17, SE22. Reion uses specialist acoustic and thermal detection equipment to locate hidden leaks in pipes, floors, ceilings, and walls without unnecessary structural damage. The £80 diagnostic fee covers the initial trace — a fixed price for any repair work is agreed before proceeding.

Southwark has a large proportion of flats — converted period houses in Camberwell, purpose-built blocks in Bermondsey, and newer riverside developments in SE1. Inter-floor leaks between flats are common and can quickly become neighbour disputes. Reion's detection service establishes the precise source before any damage is caused, covering SE5, SE15, and SE22.

To book a leak detection inspection in Southwark, call 07375 813996 or send a message. Reion aims to respond same-day for suspected active leaks. The £80 diagnostic fee covers trace and identification — a fixed repair price is agreed before any structural opening takes place.

Signs you may have a hidden water leak

Unexplained damp or staining Damp patches on walls, ceilings, or floors with no obvious cause — especially if they grow over time — are a strong indicator of a hidden leak.
Water bill increasing with no change in use If your water bill has increased significantly without a change in usage, water is escaping somewhere in your pipework.
Sound of running water Hearing water running when all taps and appliances are off suggests a leak in the supply pipework — often under floors or behind walls.
Warm patch on a cold floor A warm spot on a tiled or solid floor usually indicates a leak in an underfloor heating pipe or a buried hot water supply pipe.
Boiler pressure dropping without obvious cause If your heating system pressure drops regularly and there is no visible leak, there may be a leak within the system pipework or under the floor.
Visible mould or structural damage Persistent mould growth, crumbling plaster, or lifting floor coverings near pipework often indicate a slow leak that has been present for some time.

How we carry out leak detection

01

Initial assessment

We start by reviewing the symptoms — where damp is visible, when it appeared, and what pipework runs through the affected area. This helps narrow the search before deploying detection equipment.

02

Acoustic and thermal detection

Using acoustic listening equipment and thermal imaging cameras, we locate the leak precisely without unnecessary disruption. In most cases, the leak can be found without breaking any floors or walls.

03

Locate and confirm

Once the leak is located, we confirm the position and provide a clear report of findings. A fixed price is agreed for access and repair before any excavation or making-good work begins.

04

Repair and reinstate

We carry out the repair with minimal disruption, reinstating any surfaces disturbed during access. A pressure test confirms the repair is successful before we leave the site.

Frequently asked questions

Reion uses acoustic listening equipment and thermal imaging cameras to locate leaks behind walls, under floors, and in ceilings without speculative opening. The equipment identifies the source to a high degree of accuracy before any structural work is carried out.
The diagnostic fee is £80 for the initial trace and identification. Once the leak source is confirmed, a fixed price for any repair work is agreed before proceeding. Reion does not carry out speculative structural opening — the source is confirmed with equipment first.
Straightforward leaks are typically located within one to two hours. More complex cases — underground pipe leaks or leaks affecting multiple floors in a converted Southwark property — may take longer. Reion updates you on progress throughout.
Yes. Reion has experience tracing leaks in underfloor heating pipework, which are particularly difficult to locate without specialist equipment. Acoustic detection identifies the leak to a precise location, minimising the area of floor that needs to be opened.
Yes. Reion carries out trace-and-access work under home insurance policies for Southwark properties and provides a written report confirming the leak source and detection method, which most insurers require to process a claim.
