Local knowledge
How Haringey properties leak
Haringey housing is dominated by Victorian terraces, Edwardian semis and HMO conversions. HMO conversions with multiple bathrooms multiply the joints that can fail; we isolate and test each feed to pin the leak to one line quickly.
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 Haringey
- 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.
What fails here
Common leak problems in Haringey
01
Leaks hidden in multi-bathroom HMO conversions
Haringey has thousands of Victorian and Edwardian houses split into flats and licensed HMOs, each carrying several bathrooms, kitchenettes and shared risers. Every added wet room multiplies the compression joints, flexible tails and waste connections that can weep. Water tracks down party walls and shows two floors below the source, so we isolate and test each feed in turn to pin the leak to one line before any access is cut.
02
Perished pipework under Victorian terraces
Original lead and early copper runs beneath ground-floor floors and in solid walls corrode and develop pinholes after a century of service. On terraced streets the same buried supply often serves a whole row, so a leak can weep quietly under a hallway or bay for months. We use acoustic correlation and tracer gas to locate the exact point rather than lifting an entire floor on guesswork.
03
Central-heating pressure loss with no visible drip
A boiler that needs topping up every few days usually has a leak on the sealed system, often on a buried flow-and-return under screed or in a first-floor void. Because the water evaporates from warm pipework, there is rarely a puddle to follow. Thermal imaging and moisture mapping show the cooler wet trail against heated surfaces, letting us trace the run to a single failed joint or radiator tail.
04
Flat-roof and rainwater ingress mistaken for plumbing
Many Haringey conversions carry flat or mansard rear extensions and shared parapet gutters. Water entering through a failed felt lap or blocked internal downpipe can mimic a plumbing leak on the ceiling below. We confirm the true source before anyone opens pipework, using moisture readings and controlled testing so the trace report distinguishes weather ingress from a live supply or waste fault for your insurer.
What the data says about Haringey
How leaks behave in Haringey, and why
Converted houses and retrofitted pipework
22.8% of the stock here is converted or shared houses, more than double the London median of 8.8%, ranking 4th of 331. A house split into flats carries pipework threaded through a building never designed to hold it: waste boxed into an original chimney breast, supply chased through lath and plaster, a bathroom sitting over what used to be a bedroom.
Those retrofits are where slow leaks sit, and the runs are rarely where anyone expects. We trace them rather than assume them, which is the difference between lifting one board and lifting a room.
When the repair is your landlord's to arrange
25.2% of Haringey households are social rented, above the London median of 21% and 28th of 331. Where that applies the repair is usually the landlord's or the housing association's, and what moves it up a queue is a written location and cause. A report naming the pipe, the position and the evidence is much harder to defer than a phone call about a damp patch.
Long private supply pipes
Haringey is a borough of houses rather than blocks: 9.4% semi-detached, 25.6% terraced and 3.9% detached, with only 35.4% in purpose-built flats, close to the London median of 36.6%. More pipework runs underground and outside the building line here, across front gardens and beneath driveways, so the private supply pipe you are responsible for is simply longer than it is in a mansion block.
That changes the method rather than the price. Acoustic ground microphones and correlation along the buried run do the work a thermal camera does indoors, and pinpointing the spot is what keeps the excavation to a square metre rather than a trench.
Who supplies the water in Haringey
Water here is supplied by Thames Water, so a high-usage letter, the four-week repair window and any leak allowance claim all run through them. The pipe from the boundary stop tap into the property is yours, including the length under a garden or driveway.

Leak detection in Haringey, FAQs
How quickly can you attend a leak in Haringey?
Same-day appointments are usually available in Haringey, 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 Haringey 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 Haringey detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Haringey do you cover?
All of it, including Tottenham, Wood Green, Crouch End, Hornsey, Muswell Hill. We cover every London borough and out to the M25, so coverage never depends on which side of a postcode line you live.
A flat below mine in a Haringey conversion has a ceiling stain. Who pays to find the leak?
That usually depends on your lease and where the leak originates. In many conversions the flat owner is responsible for pipework serving their own flat, while shared or structural elements fall to the freeholder or management company. A leak detection visit helps by pinpointing the source first, so responsibility can be established from evidence rather than assumption before any repair or insurance discussion begins.
My Muswell Hill wall is damp. Is that a leak or just old-house damp?
Both are common in older Edwardian and Victorian property and can look alike. Rising or penetrating damp tends to be gradual and seasonal, while a plumbing leak often appears more localised or worsens with use. Non-invasive detection using moisture readings, thermal imaging and acoustic checks helps distinguish the two before you decide whether the fix is plumbing, or a damp-proofing job instead.
