Water Pipe Repairs London — External Supply Pipe & Water Main Specialists

A leaking or burst external water pipe is urgent. Water damage escalates quickly, water bills soar, and supply disruption causes real problems for your household or business. JD Leak Detection provide fast, professional water pipe repair services across London — including emergency call-outs for burst mains and external supply leaks.

We specialise in external underground water supply repairs. Using the latest acoustic leak detection and pipe tracing equipment, we pinpoint the exact location of your leak before we dig — minimising excavation and getting your supply restored as quickly as possible.

What Water Pipe Repair Problems We Solve

Burst water main: An emergency situation requiring immediate action. We respond quickly, locate the burst, and carry out repairs or a full pipe replacement as required.

External supply pipe leak: Leaks on the supply pipe between your boundary and your property are your responsibility. We locate and repair these efficiently, often using trenchless techniques.

Water main supply leak: Leaks on your side of the boundary stop valve — we trace the pipe, pinpoint the leak and repair or replace the affected section.

Corroded or failing pipework: Older iron, steel or lead pipework that's prone to failure. We assess the full supply and advise on repair vs replacement.

Leaking boundary stop valve: A faulty or corroded stop valve can be a major source of water loss. We repair or replace stop valves and surrounding pipework.

How We Locate Leaks — No Unnecessary Digging

Before we carry out any repairs, we use specialist equipment to locate your leak precisely:

• Acoustic leak detection — listens for the precise sound of water escaping underground
• Pipe tracing — maps the exact route of your underground supply pipe
• Ground correlation — cross-references acoustic signals to pinpoint the leak location

This means we dig only where we need to — reducing disruption, repair time and reinstatement costs significantly compared to contractors who excavate speculatively.

Emergency Water Pipe Repairs

We provide 24-hour emergency response for burst pipes and sudden loss of supply across London. If your pipe has burst, here's what to do while you wait:

1. Turn off your internal stop valve (usually under the kitchen sink or in a utility room)
2. Turn off your outside stop tap if accessible (requires a stop tap key)
3. Call us immediately on 07523 075 087
4. Photograph any visible damage or wet areas to help us assess the situation

Repair or Replace?

Not every leak requires a full pipe replacement. We will always recommend the most cost-effective solution for your situation:

• Single point leak on modern pipework — targeted repair is usually sufficient
• Multiple leaks, corroded pipe, or lead supply — full replacement is more cost-effective long-term
• Undersized supply causing pressure issues — replacement with correctly sized MDPE pipe

We provide honest, upfront advice and clear pricing for both options.

What Does a Water Pipe Repair Cost?

A single leak on modern pipework is usually a quick, targeted repair. We give you a fixed price once the leak is located. If the pipe is lead, corroded or leaking in several places, replacing it is usually better value. As a guide, our recent quotes to replace a supply from the meter to a house with new 25mm MDPE have been £1,600 to £1,650 plus VAT, including reinstatement and certification.

Remember that leaks on your side of the boundary are your responsibility, and an undetected leak keeps adding to your water bill. Finding it early is almost always cheaper.
