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

Who's responsible for drains in Ealing?
In Ealing, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Anglian Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Ealing.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Anglian Water rather than paying for the repair yourself. The separate sewer layout that dominates Ealing affects where these boundaries typically fall, and our local engineers know the W5, W6, W7 networks well enough to identify ownership quickly.
Leak Detection prices in Ealing
Every Ealing job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. The final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
