Local knowledge
How Bexley properties leak
Bexley housing is dominated by interwar semis and post-war family houses. Suspended timber floors in interwar semis let leaks travel along joists, so the damp patch often appears rooms away from the actual pipe fault.
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 Bexley
- 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 Bexley
Leak Migration Under Suspended Floors
In Bexley's many interwar semis, leaks from original lead or iron pipes under suspended timber floors travel along joists. This means the first sign of a leak (a damp patch or ceiling stain) is often rooms away from the actual pipe fault, complicating initial diagnosis and requiring systematic trace and access.
Pipe Corrosion in Interwar Systems
Original plumbing systems in pre-1950s properties are reaching the end of their service life. We frequently find pinhole leaks and general corrosion, especially at joints. Precise leak location is critical to avoid unnecessary floorboarding for insurers, ensuring claims are approved for the specific fault area only.
Inaccessible Service Runs
Water supply and waste runs in these properties are often routed through tight sub-floor voids or behind original lathe and plaster. Our trace methodology maps the exact leak point, providing the positional evidence insurers require to approve targeted, cost-contained access and repair.
Post-War Extension Plumbing Integration
Later extensions and loft conversions in post-war family houses often tied into older pipework with incompatible materials or poor junctions. These legacy integration points are common failure sites. We document the specific material mismatch or joint failure to support the claim justification.

How to Choose a Leak Detection Company in London
Choosing between companies you cannot assess technically is the hard part of a hidden leak. Six questions separate a survey from a guess, and the answers tell you more about the outcome than any review ever will.
Leak detection in Bexley, FAQs
How quickly can you attend a leak in Bexley?
Same-day appointments are usually available in Bexley, 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, where the leak is inside your own property. Attend a confirmed live leak in Bexley, fail to locate it, and the detection fee is waived. The promise stops at your boundary: if the survey shows the water is arriving from an adjoining property, a communal pipe or the supplier's main, that leak has been found and the visit is charged.
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 Bexley detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Bexley do you cover?
All of it, including Bexleyheath, Sidcup, Welling, Erith, Crayford. We cover every London borough, so coverage never depends on which side of a postcode line you live.
I own my Bexley semi outright. Is there anything that still complicates the claim?
The ownership side is as clean as it gets, so the pressure moves to the wording. Two clauses do most of the work in suburban claims of this kind. The first is the operative escape of water clause, which responds to water escaping from fixed apparatus. The second is the exclusion for wear, deterioration and gradually operating causes. A corroding pipe under a suspended floor can plausibly be read either way, so the evidence that matters is the physical failure mode, the pattern of wetting and what the surrounding timber shows at the time it is examined.
Water appeared two rooms away from where you found the leak. Will the insurer accept that?
Usually yes, provided the route is documented rather than asserted. Suspended timber floors in Bexley houses let water run along joists and under partitions, so the visible damage regularly sits well away from the failure. Adjusters see this constantly and are not surprised by it, but they will want the path shown: the origin, the intervening structure, the moisture readings along the route and the point where the water surfaced. That record also protects the reinstatement scope, because it justifies drying and repairing an area larger than the stain.
Should I strip out the damaged floor before the adjuster attends?
Do enough to prevent further damage and no more. Policies place a duty on you to mitigate, so stopping the water and lifting soaked coverings is sensible and expected. Full strip out before the loss has been inspected removes the evidence the adjuster needs to validate cause and extent, and it can turn an agreed scope into a contested one. Photograph what you do, keep what you remove where practical, and let the origin be recorded first. That order of events is what keeps the strip-out and drying costs inside the settlement.
How does the excess work on a single household policy?
The excess is the first part of any settlement that you carry yourself, and escape of water frequently attracts a higher one than the general policy excess because insurers treat it as a high frequency peril. Check the schedule rather than the summary, since the escape of water figure is often set separately. It applies once per claim, not once per damaged room, so a single failure that wets several parts of a Bexley house still carries one excess. Where a very small loss sits close to the excess, it is worth weighing the settlement against the effect of a recorded claim at renewal.
What should a detection report contain for it to be useful to an insurer?
Enough for someone who was not there to reach the same conclusion. In practice that means the date and conditions of inspection, the property type and construction, the method used and why, the location of the failure described against fixed reference points rather than vaguely, the failure mode, the extent of wetting with readings, and photographs that tie to the description. It should distinguish clearly between what was observed and what is inferred. A report that asserts a conclusion without showing the basis for it tends to generate more questions from a handler, not fewer.
