More information

What outdoor pipework replacement covers

External plumbing takes a lot of wear from cold snaps, UV, movement, and accidental knocks. Replacement focuses on removing failing sections and reinstating robust, properly supported pipework.

  • Replace leaking, corroded, cracked, or frost-split external pipe sections
  • Renew joints, fittings, and isolation valves where needed
  • Upgrade to suitable modern materials for outdoor use
  • Reroute or re-clip pipework to improve support and reduce strain on joints
  • Add pipe insulation and weather protection where appropriate
  • Test the system after installation to confirm soundness and function

When this service is most useful

  • Visible corrosion, splitting, or recurring pinhole leaks on exposed pipework
  • Drips or damp patches near external walls or along outdoor runs
  • Low flow or unreliable supply to an outside tap
  • Pipework that has frozen in previous winters
  • You need a dependable supply to a garage, garden room, or small commercial unit

How the work is carried out

The work usually starts with a site check to confirm the pipe route, access, and the best replacement approach. The water supply is then isolated and the affected section is drained down before the old pipework is removed.

New pipework is installed with appropriate fittings, clips, and supports, then insulated where needed. Once complete, the system is refilled and tested so you can be confident it is watertight before the area is left tidy.

After the replacement

You will be shown any new isolation points and what has been replaced. If there are simple steps that will help prevent repeat issues, such as better lagging or protecting exposed sections, you will get clear, practical guidance on what to do next.

Frequently Asked Questions

Do you need to dig up the garden to replace outdoor pipes?
Not always. If the problem is on exposed pipework or along an accessible route, replacement can often be done without excavation. If buried pipe needs replacing, you will be advised on the least disruptive route and what digging is required.
What materials are used for external pipework replacement?
This depends on the pipe location, exposure, and what it connects to. Common options include MDPE for below ground water supply runs and copper or plastic systems designed for outdoor use above ground. The aim is durability, correct fittings, and compliance with water regulations.
Can you replace or relocate an outside tap at the same time?
Yes, this is often done as part of the same visit if access allows. The pipework can be renewed to the tap, and the tap position can sometimes be moved to a more practical spot. Any changes to routing or making good will be agreed in advance.
How do you protect new external pipework from frost?
External pipes are clipped securely and insulated with suitable pipe lagging where needed. Vulnerable sections can be rerouted, boxed in, or fitted with better isolation and drain-down options depending on the setup. You will also get advice on how to shut off and protect outdoor supplies in winter.
Will my water be turned off during the work?
Yes, the supply normally needs to be isolated while sections are replaced and tested. The outage is usually limited to the time required to drain down, fit new pipework, and refill. You will be told what to expect before work starts.
