Water Mains Repair in Cumbria

A damaged or leaking water main can mean lost water, flooding, reduced pressure, and costly property damage. At Unblock Cumbria, we specialise in water main repair services across Cumbria and the Scottish Borders. Whether it’s a burst supply line, a cracked section, or corrosion, our teams can diagnose, repair or replace your water mains — with minimal disruption and maximum quality.

We handle the full process: leak detection, excavation or trenchless methods, pipe replacement, pressure testing, and reinstatement. Our goal is to restore clean, uninterrupted water supply safely, efficiently, and durably.

Water Main Repair Services

  • Leak detection & tracing using acoustic, pressure or dye techniques

  • Trenchless repair methods (moling, directional drilling) where possible to reduce surface disruption

  • Selective excavation & replacement of damaged pipe sections

  • Complete main renewal in extreme cases

  • Joint and coupling repairs for failing connections

  • Pipe material upgrades (MDPE, PVC, ductile iron)

  • Pressure testing & quality checks post-repair

We tailor our approach based on the severity of damage, ground conditions, and access constraints — always choosing the most effective and least invasive method.

Why Main Repairs Matter

Water mains are the lifeblood of your property’s supply system. Without reliable mains:

  • You risk water loss, flooding, and flow disruptions

  • Pressure fluctuations can damage appliances, boilers, or fixtures

  • Gradual leaks cause ground subsidence, erosion, and property damage

  • Unchecked corrosion or small cracks turn into ruptures

  • Recurrent failures and emergency callouts drive up maintenance costs

By acting early and using the right technique, you protect your property, reduce risk, and avoid cascading failures.

Frequently asked questions

How do you locate a leaking water main?

We use acoustic, pressure, and tracer techniques along with ground sensors to pinpoint the leak location with minimal excavation.

What is trenchless (no-dig) water main repair?

Trenchless repair methods like moling or directional drilling replace or repair pipes underground without full open trenching — reducing surface disruption and reinstatement costs.

Can repairs be made under driveways or gardens without tearing them up?

Yes — we often use trenchless or minimal-access techniques to reach and fix damaged sections without fully excavating your driveway or landscaped areas.

How long does a repair take?

For typical domestic mains repairs, work including detection, repair, testing, and reinstatement can often be completed in 1–2 days, depending on access, depth, and local conditions.

Will the new repair last a long time?

Yes — with modern materials and correct installation, repaired or replaced mains can last 20+ years, often matching or exceeding original pipe life.

Do I always need permissions or liaising with water authorities?

If your repair affects shared or public mains, or connections to the public supply, we’ll manage any necessary permissions, notifications or compliance with your water company on your behalf.
