Water mains specialists in Cardiff

If you need a water mains specialist in Cardiff, finding a qualified professional is key to solving leaks, bursts, and low-pressure problems safely and efficiently.

From leak detection to full pipe replacement, experts can inspect, repair, or upgrade your supply line using the latest technology — including water main moling for minimal disruption.

Typical services include:

  • Leak detection and pipe tracing
  • Lead pipe replacement and MDPE upgrades
  • Trenchless water main moling installations
  • Full water main replacement
  • New connections and diversions

Replacing old or corroded pipework can improve water pressure, flow, and quality throughout your home.

Specialists in Cardiff can recommend the most efficient and cost-effective approach for your property.

Water main replacement and moling in Cardiff

A water main replacement in Cardiff typically involves isolating the old supply, installing new MDPE pipe, and reconnecting it to the main network.

Many engineers now use moling technology — a trenchless method that allows new pipes to be installed underground with minimal digging.

Moling is ideal if your supply runs beneath driveways, lawns, or patios, reducing reinstatement costs and keeping your property disruption-free.

Water main replacement costs in the UK

The cost of replacing a water main depends on the distance from the boundary to your property, pipe size, and access. Below is a general guide of prices you can expect to pay:

  • Leak detection survey – £150-£400
  • Lead pipe replacement – £600-£1,500
  • Full water main replacement (standard domestic property) – £1,000-£2,500+
  • Water main moling installation – £1,200-£3,000+

If the route passes under hard surfaces or shared access areas, additional reinstatement fees may apply.
