Local knowledge

How Greenwich properties leak

Greenwich housing is dominated by period conversions, post-war estates and new riverside towers. New riverside developments run plastic push-fit pipework in ceiling voids; a single failed O-ring can soak several flats before it surfaces.

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 Greenwich

  • 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 Greenwich

Push-fit pipework leaks in ceiling voids

Across Greenwich's new riverside towers, plastic push-fit pipework is installed in ceiling voids. A single failed O-ring can cause a hidden leak that soaks through multiple floors before any visible signs appear. This demands urgent detection to prevent extensive structural damage to multiple flats.

Leaks in period conversion pipework

Many period conversions in the borough have ageing, often modified plumbing systems. Original lead or galvanised steel pipes may have been patched with newer fittings, creating weak points. Leaks can develop suddenly at these junctions, often within walls or under floorboards.

Post-war estate heating system leaks

Post-war estates often have centralised heating systems with ageing radiators and pipe runs. Corrosion and scale build-up over decades can lead to pinhole leaks in pipes or radiator valves. These leaks can quickly escalate, causing water damage to neighbouring units and common areas.

Balcony drain & cladding leaks in towers

Modern riverside towers with balconies and complex cladding systems are prone to drainage blockages and seal failures. Water can ingress behind cladding or seep from a blocked balcony drain into the structure, mimicking a plumbing leak and requiring immediate tracing to its source.

Leak detection in Greenwich — FAQs

How quickly can you attend a leak in Greenwich?

Same-day appointments are usually available in Greenwich, 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 Greenwich 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 Greenwich detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.

Which parts of Greenwich do you cover?

All of it — including Greenwich, Woolwich, Eltham, Charlton, Blackheath. We cover every London borough, so coverage never depends on which side of a postcode line you live.

A leak from the flat above is soaking my Royal Arsenal Riverside flat. Who is responsible?

Responsibility usually depends on where the leak originates and what your lease says, so it often becomes a dispute between the upstairs leaseholder, the freeholder and building management. A neutral leak-detection survey that pinpoints and documents the source helps everyone agree who should act and supports an insurance claim. We provide an insurer-ready report; we do not decide liability.

Can you find a leak in a period Greenwich townhouse or 1930s Eltham semi without damaging finishes?

Yes. In older concealed pipework we use non-invasive methods such as acoustic listening, thermal imaging and moisture readings to narrow the source before anything is opened up. This limits disruption to original plaster, cornicing and floors. You receive a written report showing where the leak is, typically for a fixed fee of £250 to £450 depending on access and property size.
