Leak Detection Peckham
Hidden water leaks in Peckham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Peckham buildings.
Local knowledge
Peckham housing, from a leak engineer's side
Peckham is dense with Victorian and Edwardian terraces off Bellenden Road and around Nunhead, many carved into flats, alongside newer infill blocks and large post-war estates near the high street. The terraces carry original cast-iron soil stacks, lead-jointed runs and later plastic patches, while conversions stack bathrooms and kitchens vertically so one wet room often sits directly above another. Leaks hide in these stacked wet zones, in ceiling voids between flats and behind studwork added during conversion. Push-fit joints tucked above suspended ceilings and failed cast-iron-to-plastic transitions are the usual culprits, and because so many houses are split into separate tenancies, the water frequently surfaces a floor or two from where it began.
Engineer's note
In Peckham's split houses the hardest part is proving which flat's plumbing is at fault. We map moisture across the party floor and time the staining against each unit's water use, so a downstairs tenant is not charged for an upstairs fault. Tracing the shared run before opening anything keeps neighbours, landlords and insurers on the same page.

What fails here
Common leak problems in Peckham
01
Stacked bathroom leaking to the flat below
In converted Peckham terraces the first-floor bathroom often sits directly over the ground-floor flat's kitchen. A weeping shower waste or a slow tile-tray failure drips through the joists and shows as a stain on the ceiling below. We moisture-map the floor above and run the shower under controlled conditions to confirm whether it is the waste, the tray or the sealant, then locate the exact point non-invasively before any boards come up.
02
Cast-iron soil stack weeping behind boxing
Many Bellenden Road houses still run their original cast-iron soil stack, now boxed in on each landing. Corrosion at a hub joint or a hairline crack lets waste seep out slowly, staining the boxing and rotting adjacent timber. Because it only leaks when the stack is in use, it is easily missed. We test with the stack loaded and use damp metering along its length to find the failing joint without dismantling the whole run.
03
Concealed heating pipe leak under solid floors
Estate flats and ground-floor conversions around Peckham often have heating pipes buried in screed. A pinhole corrosion leak drops system pressure and leaves a warm damp patch that migrates across the slab. We combine thermal imaging with pressure testing to trace the run and pinpoint the loss, so the floor is opened at one spot rather than lifted wholesale, and we provide a trace and access report for your insurer.
04
Push-fit joint failing above a suspended ceiling
Newer flats and shop conversions on Rye Lane hide plumbing above suspended ceilings. A push-fit elbow that was never fully engaged eventually loosens and drips onto the tiles below. The source can sit several metres from where the water appears. We use acoustic and moisture tracing to follow the run back to the loose fitting and open only the affected panel, keeping the rest of the ceiling intact.
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.
Leak detection in Peckham — FAQs
How quickly can you attend a leak in Peckham?
Same-day appointments are usually available in Peckham and across Southwark, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in Peckham?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know Peckham properties?
Yes — Peckham is dense with Victorian and Edwardian terraces off Bellenden Road and around Nunhead, many carved into flats, alongside newer infill blocks and large post-war estates near the high street. The terraces carry original cast-iron soil stacks, lead-jointed runs and later plastic patches, while conversions stack bathrooms and kitchens vertically so one wet room often sits directly above another. Leaks hide in these stacked wet zones, in ceiling voids between flats and behind studwork added during conversion. Push-fit joints tucked above suspended ceilings and failed cast-iron-to-plastic transitions are the usual culprits, and because so many houses are split into separate tenancies, the water frequently surfaces a floor or two from where it began.
Can you provide a report for my insurer?
Every Peckham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
