Water Supply Pipe, Stop Tap & Lead Pipe Replacement
The supply pipe runs from your boundary or outside stop valve into the property, and it is the owner's responsibility to repair or replace. We replace leaking and lead supply pipes and seized or failed stop taps. Many water companies replace their own lead pipe when you replace yours, so check your supplier's scheme before booking.
Older houses across Surrey and South London still have lead or ageing iron supply pipes, often narrow and sometimes shared between neighbours. A leak on the supply pipe can run for months unnoticed under a front garden, and a lead pipe can affect drinking water quality.
A stop tap that will not turn is a problem waiting for an emergency. Replacing it, or adding an accessible one, is a short job that can save a ceiling.
