Leak Detection in Eltham
Eltham's hard water supply from Thames Water creates perfect conditions for pin-hole corrosion in copper pipework, a slow leak that damages ceilings and foundations undetected. Older properties across Eltham—particularly the 30% that are Victorian—hide leaks behind plasterwork and under floorboards. Modern leak detection technology reveals where water is escaping before damage becomes expensive.
Leak detection in Eltham uses acoustic and thermal methods to locate hidden water loss, especially pin-hole corrosion from hard water in Victorian pipes. Detection prevents ceiling damage, mold, and high water bills across Eltham's older housing stock.
Drainage in Eltham — what local engineers know
Thames Water's supply to Eltham is classed as hard water, with calcium and magnesium levels that corrode copper joints within 10–15 years. Most of Eltham's Victorian and Edwardian homes were plumbed with copper tube, now ageing past its design life. Greenwich Council's water board data shows Eltham properties face above-average water loss claims. Silent leaks in Eltham's older housing can waste 150+ litres daily before becoming visible, pushing water bills up and risking mold and structural rot.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Eltham
- Combined sewerage infrastructure — common in older parts of Eltham — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Large Victorian and Edwardian housing stock in Eltham means clay soil pipes and brick-built inspection chambers are common — CCTV surveys frequently reveal root ingress and joint displacement

Who's responsible for drains in Eltham?
In Eltham, 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 Eltham affects where these boundaries typically fall, and our local engineers know the SE9, SE10, SE11 networks well enough to identify ownership quickly.
Leak Detection prices in Eltham
Every Eltham 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 — significant in Eltham, where around 30% of 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.
