Leak Detection in Greenwich
Greenwich sits at the centre of Thames Water's hardest supply zones, where water mineral content accelerates pinhole corrosion in copper pipework and joint failure in older systems. Silent leaks in Victorian soil pipes and under-floor copper lines waste thousands of gallons annually and trigger timber decay, mould, and rising damp before any visible sign emerges. Detection technology pinpoints the exact location, eliminating costly exploratory excavation.
Leak detection in Greenwich identifies pinhole corrosion, slow seepage, and hidden water loss in copper pipes and Victorian drains. Hard water from Thames Water accelerates copper failure; acoustic and pressure testing pinpoint leaks before structural damage occurs.
Drainage in Greenwich — what local engineers know
Thames Water's Greenwich supply averages 450–520 mg/L total hardness—well above the 300 mg/L threshold where copper corrosion accelerates. Properties built before 1990 in SE10, SE11, SE12, and SE13 are at highest risk; pinhole leaks in first-fix copper can perforate within 5–8 years of installation if corrosion inhibitor depletion occurs. Greenwich Council's water mains network also contributes mineral load during peak summer demand. Left unresolved, problems like this can lead to expensive structural or water damage.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Greenwich
- Combined sewerage infrastructure — common in older parts of Greenwich — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Large Victorian and Edwardian housing stock in Greenwich means clay soil pipes and brick-built inspection chambers are common — CCTV surveys frequently reveal root ingress and joint displacement
- Greenwich has Environment Agency flood warning areas nearby along the River Thames corridor — basement and ground-floor properties can face sewer backflow during heavy rain; non-return valves are strongly recommended.

Who's responsible for drains in Greenwich?
In Greenwich, 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 Greenwich.
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 combined sewer layout that dominates Greenwich affects where these boundaries typically fall, and our local engineers know the SE10, SE11, SE12 networks well enough to identify ownership quickly.
Leak Detection prices in Greenwich
Every Greenwich 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. However, the final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition — significant in Greenwich, where many homes are Victorian and often run on original clay pipework — 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.
In summary, Leak Detection in Greenwich is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
