Leak Detection Welling
Hidden water leaks in Welling pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Welling buildings.
Local knowledge
Welling housing, from a leak engineer's side
Welling is largely interwar semis on tightly laid estate roads, with 1930s shop parades along the Welling and Bellegrove corridors and a few older cottages nearer the crossroads. As across the borough, these semis sit on suspended timber floors, so a supply or heating leak under one room routinely tracks along the joists and shows up beneath a skirting or bay several metres away. Rear extensions here tend to bury heating pipes in solid floors, and plenty of homes still run original pipework hidden by later decorating. The result is a stock where damp appears confidently in the wrong place while the failing joint sits quietly elsewhere under the boards.
Engineer's note
In Welling I treat the bay-window damp as a clue, not the answer. The joists carry water to the outer wall, so I moisture-map the floor and read it thermally to trace it back, then pressure test circuit by circuit to prove the source. One documented access hole beats guessing, and the report is ready for your insurer.

What fails here
Common leak problems in Welling
01
Bay window damp from a hidden feed
Welling semis often show damp under the front bay when the real fault is a weeping feed pipe further back under the floor, the water having run down the joists to the coldest outer wall. We map moisture across the room, follow the trail with thermal imaging to the true joint, and confirm with pressure testing before lifting a single board, working to a fixed fee agreed at the booking.
02
Solid-floor heating leak in an extension
Kitchen and dining extensions in Welling frequently carry the heating loop in screed. A buried leak here shows as recurring pressure loss and a warm damp bloom rather than a drip, so it is easily missed. Thermal imaging maps the buried pipe and per-circuit pressure testing isolates the failing leg, letting us open just the small area of floor above the fault instead of the whole extension slab.
03
Corroding original pipe behind plaster
Stretches of original galvanised or early copper pipe still run through walls in many Welling houses, and pinhole corrosion weeps for months, blistering paint before anyone suspects plumbing. We locate the exact point with acoustic listening and thermal imaging, cut one tidy access hole, and hand over an insurer-ready trace and access report so a claim reflects precisely what was found.
04
Condensation confused with a pipe leak
Cold outer walls in these interwar semis can throw up condensation damp that looks like a leak, tempting a homeowner to open a wall for nothing. We begin non-invasively with moisture readings and thermal scans to establish whether there is a pressurised leak at all. On a no find, no fee basis you are never charged to chase damp that turns out to be environmental.
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 Welling — FAQs
How quickly can you attend a leak in Welling?
Same-day appointments are usually available in Welling and across Bexley, 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 Welling?
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 Welling properties?
Yes — Welling is largely interwar semis on tightly laid estate roads, with 1930s shop parades along the Welling and Bellegrove corridors and a few older cottages nearer the crossroads. As across the borough, these semis sit on suspended timber floors, so a supply or heating leak under one room routinely tracks along the joists and shows up beneath a skirting or bay several metres away. Rear extensions here tend to bury heating pipes in solid floors, and plenty of homes still run original pipework hidden by later decorating. The result is a stock where damp appears confidently in the wrong place while the failing joint sits quietly elsewhere under the boards.
Can you provide a report for my insurer?
Every Welling detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
