Water Mains & Lead Pipe Replacement
Water Mains & Lead Pipe Replacement
Old lead or narrow-bore mains supplies are still common in Barnet's Victorian and Edwardian houses. Replacing them improves pressure and removes lead from your drinking water.
Water Mains & Lead Pipe Replacement in North London, done properly the first time
We replace lead and undersized supply pipes with 25mm MDPE, either by open trench or moling where the drive and garden allow, connecting to the external stop tap and bringing the new supply into the house with a new internal stopcock.
Better flow and pressure makes a real difference if you're moving to an unvented cylinder or a high-output combi. We coordinate with Thames Water where a boundary connection is needed and make good the ground when we're finished.

Your questions, answered
How do I know if I have lead pipes?
Lead pipe is dull grey, soft enough to scratch and has swollen joints. We can check the incoming pipe at your stopcock during a visit.
Will a new supply improve my water pressure?
Usually yes — most poor pressure in older Barnet homes is caused by a narrow or partly furred supply pipe rather than street pressure.
Do you have to dig up the whole drive?
Not always. Moling lets us pull a new pipe through with just a small pit each end where ground conditions allow.
Does Thames Water need to be involved?
For the connection at the boundary, yes. We handle the coordination as part of the job.
