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

Illustrative example of typical work

Pin-Hole Corrosion, Copper Riser, SE10 Eltham Property

Eltham
Service:
Leak Detection

An SE10 Eltham homeowner noticed soft spots in the ceiling plaster but found no dripping. Acoustic leak detection identified a pin-hole weep in the main copper riser behind the walls. The SE10 Eltham property's hard-water supply had corroded the joint after 25 years; replacement with PEX tubing eliminated further risk.

Leak Detection in Eltham — FAQs

Why does Eltham water cause copper corrosion?
Thames Water's supply to Eltham is hard water with high mineral content. Copper naturally oxidizes in hard water, and Eltham's Victorian pipework—often 80+ years old—has exceeded safe lifespan.
How do you find a leak hidden in Eltham walls?
Thermal imaging and acoustic sensors detect water flow behind surfaces without cutting into walls. We map the leak location precisely, then advise on access and repair options for your Eltham home.
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.
