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
Damp Patches Away from Plumbing
In Bexley's many interwar semis, leaks from pipes under suspended timber floors can travel along joists. This means the visible water damage often appears in a completely different room from the actual burst or faulty connection. You might see damp in your living room ceiling while the leak originates in a bathroom pipe above.
Concealed Leak Detection
Because water follows the path of least resistance under floorboards, a small leak can cause significant hidden damage before you spot it. Our engineers use specialised acoustic and thermal imaging equipment to pinpoint the exact source without unnecessary floor lifting. This is crucial for preserving original floorboards in these period homes.
Aged Lead and Iron Pipes
Original plumbing in older Bexley houses may still use lead supply pipes or galvanised iron waste pipes. These materials corrode and weaken over decades, leading to pinhole leaks or sudden bursts. A leak detection survey can identify these aging systems before they fail catastrophically.
Outdoor Stop Tap Access
Many family homes in the borough have their main stop tap located under the front garden path or driveway. If this becomes stiff or seized, you cannot quickly isolate a major leak. We carry tools to free and repair external stop taps so you can regain control of your water supply immediately.

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 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. Every detection visit in Bexley 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 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.
Why does damp appear in a different room from the leak in my Bexley semi?
Many Bexley homes have suspended timber floors, so water from a leak can run along the joists and follow the timber before it soaks through anywhere visible. The damp patch you see often marks where water finally collected, not where it escaped. Tracing the run methodically, rather than opening up near the stain, usually locates the true source.
Can you find a leak under a solid extension floor without digging it up?
Often yes. Heating pipes buried under solid extension floors are common in Bexley's post-war and extended houses, and a slow loss there is hard to spot. Non-invasive tracing methods can narrow the position before anything is lifted, which limits disruption. A typical fixed fee for this kind of detection sits in the usual UK trade cost-guide range of around £250 to £450.
