Leak Detection in Hammersmith
Hidden leaks in Hammersmith properties can waste thousands of gallons before you spot the damage. In hard-water areas supplied by Thames Water, pinhole corrosion in copper pipework is a silent threat affecting Victorian homes in W8, Edwardian terraces in W6, and even modern flats in W7 and W9. The separate sewer system in Hammersmith adds complexity: surface water and foul drains require different detection approaches.
Leak detection in Hammersmith uses thermal imaging, listening equipment, and overnight pressure testing to find hidden water loss. Thames Water's hard water supply accelerates pinhole corrosion in copper pipes common in Hammersmith's Victorian and Edwardian properties. Early detection prevents structural damage and high water bills.
Drainage in Hammersmith — what local engineers know
Hammersmith is supplied by Thames Water, which provides hard water that accelerates corrosion of copper pipes – a particular concern in the Victorian and Edwardian properties that make up much of Hammersmith's housing stock. Hounslow Council's building stock includes cast iron soil pipes and galvanised steel laterals that often develop pinhole leaks after 40–60 years of service. Hammersmith's older properties typically hide pipework in cavity walls, making visual inspection impossible; thermal imaging and listening equipment are essential for accurate detection in Hammersmith.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Hammersmith
- Separate sewer system across most of Hammersmith: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Coastal salt-laden air in Hammersmith accelerates corrosion of external soil stacks, pipe brackets and galvanised fittings on exposed elevations
- With 32% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Hammersmith?
In Hammersmith, 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, Thames 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 Hounslow.
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 Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Hammersmith affects where these boundaries typically fall, and our local engineers know the W6, W7, W8 networks well enough to identify ownership quickly.
Leak Detection prices in Hammersmith
Every Hammersmith 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.
