Domestic Water Main ReplacementDone Right, First Time.
Low pressure, frequent leaks or an old lead supply pipe? We replace your water main with modern MDPE pipe from the boundary stopcock to your home, then reinstate the ground properly once the work is done.
What We Do
From diagnosis to reinstatement, everything is handled by our own team.
MDPE Pipe Replacement
Your old supply pipe replaced with modern blue MDPE pipe, resistant to corrosion and built to last for decades.
Lead Pipe Replacement
Many older properties still have a lead supply pipe. We replace it with MDPE to remove the risk to your water quality.
New External Stopcock
Installation or replacement of the external stopcock where your supply pipe enters the property boundary.
Trenching & Reinstatement
Careful excavation along the pipe run, followed by proper reinstatement of lawn, paving or driveway once the new pipe is in.
Water Company Liaison
We handle the notifications and paperwork required by your local water company, so the job is fully compliant.
Pressure & Flow Testing
Once the new main is connected, we test pressure and flow to confirm the replacement has solved the problem.

Signs You Might Need a New Water Main
A water main rarely fails without warning. Here's what to look out for.
Persistently Low Pressure
Water pressure that's dropped gradually over time, or is noticeably worse than at neighbouring properties, often points to a failing supply pipe.
Discoloured or Metallic Water
Water that looks discoloured or has a metallic taste can be a sign of an old or corroding lead supply pipe.
Lead Supply Pipe
If your property was built before 1970, there's a good chance your water main is still lead. We can check and replace it.
Recurring Leaks
If you've had more than one leak on the same run of pipe, replacement is usually more cost-effective than repeated repairs.
Damp Patches in the Garden
An unexplained damp or soft patch in the garden or under the drive can mean your supply pipe is leaking underground.
Water Company Notice
If your water company has flagged the condition of your supply pipe, we can carry out the replacement to their requirements.
Frequently Asked Questions
What's Involved in a Water Main Replacement
We start with a site visit to establish the route of your existing supply pipe, check for any lead pipework, and agree the best path for the new main.
Once work begins, we excavate along the pipe run, lay the new MDPE pipe, and connect it at the boundary stopcock and at the property.
After connection, we pressure and flow test the new main to confirm the problem is resolved, then reinstate the ground, whether that's lawn, paving or driveway.
Every replacement comes with a written guarantee, and we handle any water company notifications required along the way.
