Leak detection in Bexley

Non-invasive water leak detection, repair and insurance reporting across Bexley and the surrounding area. Thermal imaging, acoustic correlation and tracer gas find the source precisely — before anyone lifts a floor or opens a wall.

Covered by our South East London team.

Local knowledge

What actually leaks in Bexley

Bexley is overwhelmingly interwar and post-war suburban housing, with the northern edge at Erith and Thamesmead sitting on Thames marshland. That marsh ground is soft, holds water, and moves, so drain runs crack and solid floor slabs settle, and a leak in that ground spreads laterally rather than draining away.

That is not trivia. It changes where we start. Knowing that a Bexley property is likely to be on Thames Water mains, built the way most of the stock around it was built, and sitting on the ground it sits on, means we can rule out whole categories of fault before we unpack the van — which is time you are not paying for.

The faults we are called to most often here

  • Marshland ground movement cracking drains at Erith and Thamesmead
  • Solid floor leaks spreading laterally in soft ground
  • Interwar supply pipework failing at ninety years old
  • Flat roof failures on post-war housing and extensions
  • High water table complicating damp diagnosis

Equipment

How we survey a property in Bexley

Every van carries the full range. Which instrument leads depends on the pipe, the pressure and the ground it is buried in.

  • Thermal imaging camera survey

    A radiometric camera reads surface temperature through plaster, screed and tile to reveal the cold plume of an escaping supply pipe or the warm track of a heating leak.

  • Acoustic leak correlation

    Ground microphones and digital correlators listen for the specific hiss of pressurised water forcing its way out of a pipe, then triangulate the exact point.

  • Tracer gas testing

    A harmless hydrogen and nitrogen mix is introduced into drained pipework, escapes at the fault, and is picked up at the surface by a gas sensor.

  • Moisture mapping and salts analysis

    Pin and pinless meters chart how wet a structure is, and a salts test tells us whether the water arrived from a pipe, from the ground, or from the weather.

  • Pressure and flow testing

    Isolating and pressurising each circuit in turn proves which one is losing water, and how fast, before anything is opened up.

  • CCTV drainage survey

    A self-levelling camera crawls the drain run and records exactly what is broken, where it is, and how deep.

  • Borescope inspection

    A camera on a flexible probe goes through a hole the size of a pencil to look inside a void, wall or ceiling.

  • Tracer dye testing

    Non-staining fluorescent dye is added to one water source at a time so the escaping water carries a colour-coded label.

  • Pipe and cable tracing

    A signal generator puts a tone on the pipe and a receiver follows it, so we map the route and depth before anyone digs.

  • Roof integrity and voltage testing

    Low-voltage electronic testing finds breaches in a flat-roof membrane that are invisible from the surface.

What causes most leaks in Bexley?

Bexley is overwhelmingly interwar and post-war suburban housing, with the northern edge at Erith and Thamesmead sitting on Thames marshland. That marsh ground is soft, holds water, and moves, so drain runs crack and solid floor slabs settle, and a leak in that ground spreads laterally rather than draining away. In practice that means the faults we are called to most often here are marshland ground movement cracking drains at erith and thamesmead, solid floor leaks spreading laterally in soft ground, interwar supply pipework failing at ninety years old.

Who is responsible for a leak on my supply pipe in Bexley?

Mains water in Bexley is supplied by Thames Water. As a general rule the supply pipe from the boundary stop tap into your property is yours to maintain, and everything on the street side belongs to the water company. Our report states which side of that boundary the fault sits on, which matters because many water companies will repair a first leak on a customer supply pipe at no charge.

How much does leak detection cost in Bexley?

The same as everywhere else we work — there is no Bexley premium. Weekday surveys start at £54.00 + VAT with a half-hour minimum and no call-out fee, evenings and weekends from £69.75 + VAT, and late nights from £90.00 + VAT.

Will my insurer accept a leak detection report from you?

Our reports are written to the evidence standard loss adjusters work to: calibrated moisture readings, dated photographs, a stated methodology and a clear causation finding. Trace and access cover in your buildings policy will usually pay for the survey itself as well as the damage caused by getting to the leak.
