Keeping Your Clean Water Flowing

Most of the time, people call us about dirty water (drains). But the pipe that brings fresh, clean drinking water into your home is just as important.

Your Water Main (or supply pipe) runs underground from the street boundary to your internal stopcock. If it leaks, bursts, or gets old, it can cause low pressure, high bills, and damage to your property.

In simple terms: We look after the pipe that brings fresh water into your property—fixing leaks, installing new supplies, and improving pressure.

Why Do Water Mains Fail?

Unlike drains, your water supply pipe is under constant pressure. Over time, things can go wrong due to:

  • Age: Many older homes still have lead or iron pipes that corrode or pose health risks.
  • Movement: Ground shifting in winter can snap rigid pipes.
  • Tree Roots: Putting pressure on the pipe.
  • Accidents: Damage caused during building work.

You usually know you have a problem if your water bill spikes, your pressure drops, or you find a soggy patch of grass in the garden that never dries out.

Our Water Main Services

We cover everything from a quick repair to a full new installation. Here is an overview of how we can help:

1. Find & Fix Leak RepairStop the Wastage. If you have a leak but don’t know where it is, we use listening devices to find it. Once located, we dig a small, targeted hole to repair the pipe and get your water flowing safely again. If the leak is not audible and there are no obvious signs, we can cut and cap the pipe in various places to locate the leak.

2. Water Main Installations & Re-RoutesMoving Pipes or Installing New Ones. Whether looking to upgrade or replace an existing supply, install a brand new one or re-route pipework around planned building works, we’ve got you covered.

3. Water Main RepairsUrgent Fixes. If you have a burst pipe or a sudden loss of water, our teams can excavate and repair the damaged section to restore your supply quickly.

4. Moling (Trenchless Installation)The “No-Dig” Solution. Need a new water pipe but don’t want to dig up your driveway? We use a “Mole”—a pneumatic device that tunnels underground to lay your new pipe without trenching through your garden or paving.

The Benefits to You

  • Lower Bills: Fixing a leak stops you paying for water that is soaking into the soil.
  • Better Pressure: New, larger pipes can improve the flow to your showers and taps.
  • Safety: Replacing lead pipes removes harmful metals from your drinking water.
  • Minimal Mess: Our moling technology saves your surfaces from excavation.
