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 Failures
In Greenwich's new riverside towers, plumbing systems often use plastic push-fit pipework concealed in ceiling voids. A single failed O-ring or joint can leak silently for extended periods, saturating multiple flats before water damage becomes visible in ceilings or walls. This hidden nature creates complex multi-property claims that require urgent professional tracing to establish the source and limit liability.
Leak Migration in Period Conversions
Many period properties in Greenwich have been converted into flats, sharing original plumbing stacks and floor structures. A leak from an upper-floor bathroom can travel along joist channels or through service ducts, emerging in a completely different flat. Our trace and access procedures are designed to map this migration path definitively for insurer approval.
Estate System Complexity
Post-war estates in the borough frequently have interconnected heating and water systems serving multiple dwellings. A failure in a central riser or a communal pipe can affect numerous properties simultaneously. Precise leak location is critical here to determine responsibility and ensure the insurer only covers damage for the specific policyholder's unit.
Concealed Damage in Voids
Across all Greenwich property types (from towers to conversions), ceiling voids, boxing, and underfloor spaces are common. Leaks in these concealed areas cause significant secondary damage before any visible signs appear. Our detection methods use minimal invasive techniques to pinpoint the exact failure point, providing the evidence insurers need to approve comprehensive repair claims.

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, where the leak is inside your own property. Attend a confirmed live leak in Greenwich, 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 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.
I am a leaseholder at Royal Arsenal. Why can't I just get my own contractor in?
Because on an estate of that structure the buildings insurance and the repairing obligation for the structure both sit with the freeholder or the management company, and the policy will respond to work they authorise rather than work you commission. Instructing your own contractor for structural drying or repair risks paying for it yourself. What you can and should do is report promptly, press for the origin to be established, and document the condition of your flat. Anything inside your demise that the lease makes yours, and your possessions, are a separate matter for your own cover.
My Greenwich house is listed. Does that change the settlement?
It changes the specification, which changes the figure. Works affecting the special interest of a listed building need consent, and that can extend to plasterwork, joinery, windows and floors that a standard schedule would replace in modern materials. The right moment to raise it is when the scope is drafted, not after a sum has been agreed, because a settlement calculated on ordinary rates will not fund matching work. Say clearly that the property is listed, identify the affected elements individually and keep the consent requirement visible in the correspondence.
Several flats are damaged from one failure. Is that one claim or several?
Normally one claim against the block or estate policy, with a single excess, brought by the freeholder or managing agent as the insured. Each affected leaseholder may have a separate contents claim of their own. The reason this matters is timing: a single claim is investigated once and settled once, so a delay in establishing the origin holds up everybody, not only the flat where the water surfaced. It also means the adjuster is assessing a cumulative figure, which usually brings a more thorough investigation than a small individual loss would attract.
What does the estate need from me to progress the repair?
Written notification with a date, a description of what you found and photographs taken before anything was moved or cleared. Then access, both for inspection and for drying equipment, arranged rather than assumed. Where the origin appears to be outside your flat, the estate will need something better than a description of a wet ceiling in order to justify entering another demise, which is where an independent technical finding is worth having. Keep every exchange in writing; managed estates work through records, and a verbal report to a concierge tends to disappear.
Who pays the service charge consequences of a claim on the estate policy?
The excess is generally treated as a claim cost and recovered through the service charge across the contributing leaseholders, and any uninsured element of the repair reaches residents the same way. Over time, a run of water losses also affects the premium the estate is quoted, and that too arrives as a charge. None of that is a reason to avoid notifying a genuine loss. It is a reason why estates and their insurers increasingly want a cause identified and closed out rather than a ceiling patched and the same failure repeating a year later.
