Plumbing Leak Detection for homes and local properties

Plumbing Leak Detection jobs are rarely just about swapping one part and leaving. A proper visit starts with checking the wider system, confirming what caused the fault and making sure the repair or installation suits the property.

Locate hidden leaks in walls, floors and boxed-in pipework. In and around Twickenham, that often means working around older pipework, limited access or systems that have been altered over time. We keep the process simple: assess the job, explain the options, agree the price, then complete the work as neatly and efficiently as possible.

For urgent issues, calling is usually the fastest route. For planned work, we can advise on the most practical repair or replacement based on the condition of the existing system.

Leak Detection in Twickenham — Finding Hidden Leaks Without Unnecessary Damage

Water leak being investigated in a Twickenham property

A leak you can see is straightforward to fix. A leak you cannot see — hidden behind plaster, under floors, within ceiling voids or beneath concrete — requires systematic investigation before any repair work can begin. Opening up walls and floors speculatively to find a hidden leak wastes time, causes unnecessary damage and increases costs. Jay Plumbing uses detection methods that locate hidden leaks accurately before any opening-up takes place.

Unexplained increases in water bills, damp patches on walls or ceilings, the sound of running water when all outlets are closed, or a water meter that continues to run after the household supply is isolated are all signs of a hidden leak. Each requires a different investigation approach depending on the plumbing system, the type of pipe and the likely location.

Our detection methods include thermal imaging to identify temperature differences associated with water movement, acoustic detection to locate the sound signature of pressurised leaks, and systematic pressure testing to isolate which circuit the leak is on. These techniques avoid unnecessary damage to surfaces and structure.

Detection methods

How We Find Hidden Leaks in Twickenham Properties

Pressure testing — The water system is isolated in sections and pressure-tested using a gauge. A section that loses pressure over time contains the leak. This technique narrows down the location to a specific pipe run without any invasive work, making subsequent opening-up targeted rather than speculative.

Thermal imaging — Water escaping from a pressurised pipe alters the surface temperature of the surrounding material. A thermal camera detects these temperature differences through walls, floors and ceilings, often pinpointing the leak location to within a few centimetres. Particularly effective for underfloor leaks and leaks within screed.

Acoustic detection — Pressurised water escaping from a small hole or crack produces a sound signature that acoustic detection equipment can pick up through floors, walls and ground. The technique can locate leaks in buried or concealed pipes without excavation.

Trace and access — Once the leak is precisely located, we open up only the specific area needed to access the pipe. This minimises damage to decoration, tiles and structure. After repair, we advise on making good the surface, though decorative reinstatement is generally the homeowner's responsibility.

Insurance leak investigations — If you are making a home insurance claim for a leak, our detection reports set out the investigation method used, findings and the nature of the fault. This documentation supports the claim process with your insurer.

Check your meter: To confirm whether you have a hidden leak, turn off all water outlets and check your water meter. If the meter dial is still moving with all outlets closed, water is escaping somewhere in the supply system. Call us to investigate.

Condensation versus leakage — Damp patches and ceiling staining are sometimes caused by condensation rather than active leaks. We can establish which is the case during our investigation, which affects both the repair approach and any insurance implications.

Questions & answers

Leak Detection FAQs

My water bill has increased but I can't see a leak — what should I do?

Check your water meter first. Turn off all taps and water-using appliances, then look at the meter — if it is moving, there is a leak somewhere. If the meter is still when the inside stopcock is closed but moves when it is open, the leak is within the property. If it moves even with the stopcock closed, the leak may be in the external supply pipe. Call us to investigate either scenario.

Will you need to lift my floor to find a leak?

Not necessarily, and not before we have used non-invasive detection methods first. Our detection approach is designed to locate the leak precisely so that if lifting floor or opening walls is needed, it is done in the right place. In many cases, leaks can be located and access limited to a very small area.

Can you detect leaks in underfloor heating pipes?

Yes. Underfloor heating pipe leaks are among the more challenging detections, particularly in solid floor constructions where the pipe is embedded in screed. Thermal imaging and pressure testing are both effective techniques for locating leaks in these systems without wholesale removal of the floor covering.

Will my insurer cover trace and access costs?

Many home insurance policies include trace and access cover, which pays for the cost of finding and accessing a hidden leak (though not always the repair itself). Check your policy documentation or call your insurer before booking. We can provide a report in a format suitable for insurance claims.
