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, so long as the leak is one arising inside your own property in Bexley: attend, fail to locate it, and you are not charged the detection fee. It is not cover against the leak being someone else's. Where the trace ends at a neighbouring property, a communal riser or the mains before your boundary, we have located it and the visit is payable.
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.
There is water under the floorboards of our Bexley semi. Does that have to wait for daylight?
No. That is one of the few situations easier to deal with at night than it sounds. A suspended timber floor can be opened at a board rather than a slab, so the run can be seen directly with a lamp and the wet section followed back along the joists. The caution is electrics, because cables often share the same void, so power to the affected circuit comes off before anyone reaches in. We will ask you about that on the phone. Lift a board near the wet area rather than at the middle of the room, since services usually run along the wall line.
Our outside stop tap will not turn. Is that worth sorting before an emergency?
Yes, and it is one of the few genuinely useful things to check on a dry evening. Outside taps in Bexley's older paths sit in a narrow chamber that fills with grit, and a tap nobody has moved since the 1970s will often refuse to shift when it matters. Clearing the chamber and testing it takes minutes in daylight. Finding it seized while a pipe is running is what turns a contained leak into a soaked floor. A cheap stop tap key kept in a kitchen drawer is worth having before you need one.
What should we switch off before anyone gets here?
The water at whichever tap holds, and the electrical circuit serving any room where water has reached a light fitting, a socket or a ceiling. Modern boards make that straightforward: the lighting circuits are usually labelled and you can drop one without putting the whole house in darkness. Leave the heating alone unless it is the heating that is leaking. If you cannot tell which circuit is affected and water is coming through a ceiling rose, switch the lighting off entirely and use torches until somebody can look properly.
The floor void has been wet for a while. What happens after the leak is fixed?
Drying, and it takes longer than people expect. A sub-floor void in a Bexley house is designed to be ventilated rather than drained, so once water has collected in it the moisture leaves slowly through the airbricks unless something helps it. Joist ends bedded into the wall, the wall plate they sit on and the underside of the boards all hold water, and timber that stays damp invites rot and infestation long after the plumbing has been sorted. The practical steps are clearing the airbricks so they actually ventilate, lifting a board or two to let air circulate, and where there has been standing water, getting a dehumidifier and a fan into the space. Putting the floor back down over a wet void is the mistake that turns a plumbing bill into a joinery one.

Leak detection is not one technique. It is a sequence: prove there is a leak, work out which system it is on, then use the method that suits the pipe, the floor and the failure. Here is how each method works and what defeats it.
