Leak Detection in Ealing

Your Ealing water meter is rising but you see no visible leaks; cold spots appear on ceilings in W6 or W7; boiler pressure drops weekly despite the system being sealed. These are classic signs of pin-hole corrosion in copper heating pipes or concealed cold-water feeds under floorboards. Ealing's hard water (Anglian Water supply, ~300 mg/L hardness) accelerates corrosion at copper joints and stress points, especially in 1950s–1980s properties where 15mm copper was standard. Our thermal imaging and acoustic listening pinpoint the exact leak location without cutting into walls or ceilings.

Hidden leaks in Ealing are often pin-hole corrosion in copper pipes, accelerated by hard water and pipe age. Thermal imaging detects cool water-escape patches; acoustic listening pinpoints the hiss under pressure. We confirm water loss, isolate the damaged section, and replace with modern microbore or alternative materials in 2–4 hours.

Drainage in Ealing — what local engineers know

Anglian Water supplies Ealing at moderate hardness, depositing calcium carbonate inside copper pipes. Stress points—bends, compression joints, areas of high water velocity—corrode first, creating pin-holes that leak 1–5 litres per hour invisibly. Cast iron soil pipes in Victorian Edwardian properties (W5, W6, W7) decay from inside outward over 80+ years; exterior seepage into gardens or party walls risks Ealing Council enforcement action. We locate the failure point using thermal imaging (detecting cool water escape patches) and acoustic listening (detecting hiss under pressure), then isolate and replace only the damaged section.

  • Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Ealing
  • Separate sewer system across most of Ealing: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
  • Ageing infrastructure in parts of Ealing means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Illustrative example of typical work

Concealed Pin-Hole Leak in 1970s Heating Pipes, Ealing W6

Area:
Ealing
Service:
Leak Detection

An Ealing W6 customer's boiler pressure dropped from 2 bar to 0.5 bar over two weeks; no visible leaks anywhere. Thermal imaging revealed a tiny pin-hole in 15mm copper buried under kitchen floorboards—hard water had corroded the pipe over 30 years at a compression joint. Acoustic listening confirmed the leak rate (~2 litres/hour). We isolated the damaged 3-metre section, replaced it with modern pipework routed through the loft void, and re-pressurized with fresh inhibitor. Boiler pressure now stable; heating bills reduced noticeably.

Leak Detection in Ealing — FAQs

Why do Ealing copper pipes develop pin-holes?
Ealing's mains water (Anglian Water, ~300 mg/L hardness) deposits scale inside copper pipes and can promote localized corrosion at joints and bends, especially if chlorine levels are slightly elevated or water is slightly acidic. Pipes from the 1960s–1980s are now 40–60 years old and increasingly vulnerable. High-velocity zones near pump outlets and tight bends corrode fastest. Inhibitor-dosed sealed systems resist this longer than open-vented systems.
How does thermal imaging detect hidden leaks?
Escaping water cools the surface above the leak. Our thermal imaging camera detects this temperature difference and narrows the leak location to within 30cm. Combined with acoustic listening (which picks up water hissing under pressure), we can identify pin-holes in pipes under floors, behind cavity walls, or inside cupboards without excavation. This is especially valuable in Edwardian properties in Ealing W7 where plumbing runs through multiple hidden cavities.
Should I descale my heating pipes if I live in Ealing?
Yes, especially if your property is pre-1995 and uses original copper pipework. Ealing's hard water accumulates scale inside heating pipes, increasing system pressure and stress on corroded sections. A powerflush removes existing scale; a water softener (optional) prevents new buildup. Together, these extend heating system life by 10–15 years and improve efficiency by 8–12% in hard-water Ealing homes.
How do you find a leak without digging?
A combination of acoustic listening sticks, thermal cameras, moisture mapping and inert tracer-gas injection lets us triangulate a leak to within a few centimetres before any opening-up is needed.
Will my insurance cover the cost?
Most UK home-insurance policies include 'trace and access' cover for leak detection. We bill the insurer directly on approved claims.
What leaks can you find?
Mains supply leaks, central heating leaks, hot and cold pipework, underfloor heating, shower-tray leaks, and concealed waste-pipe leaks.
How long does a leak-detection visit take?
Typically 1-3 hours on site, followed by a written report within 48 hours suitable for insurance submission.
