Replacing Pipework in Cumbria

Sometimes drain damage is too far gone — cracked pipes, collapsed sections, or misaligned runs may require full pipework replacement rather than patch fixes. At Unblock Cumbria, we specialise in replacing entire drain runs safely and efficiently across Cumbria and the Scottish Borders. Our objective is to restore optimal flow, structural integrity, and long-term reliability with minimal disruption.

We combine expert diagnostics, careful planning, modern materials, and precision installation to give you a drainage system you can trust for decades. Whether under driveways, gardens, roads, or buildings, we plan for the environment, access constraints, and long-term performance.

When Replacement Needed

Pipe replacement becomes essential when:

  • The pipe has collapsed or caved in

  • Multiple repair patches are failing or ineffective

  • The pipe alignment is severely shifted or distorted

  • The drain is severely misaligned or had multiple joint separations

  • Damage is widespread or structural (e.g., corrosion, external pressure)

  • The existing material is outdated (e.g. old clay or deteriorating pitch fibre)

  • Floor levels or site works require rerouting a full drain run

When repair no longer offers a sustainable solution, replacement provides a clean slate and long-term peace of mind.

Pipe Replacement Services

  • Full strip-out of defective drain stretches

  • Excavation and trenching with minimal structural impact

  • Installation of modern pipes (PVC, HDPE, uPVC, resistant materials)

  • Bedding, bedding material compaction, and alignment works

  • Proper jointing, sealing, flexible coupling integration

  • Reconnection of inlets, outlets, inspection chambers

  • Post-installation testing (water/air pressure tests or CCTV)

  • Reinstatement of surfacing, landscaping, hardscaping

We adopt a strategy that balances excavation efficiency, structural stability, and post-work reinstatement neatness — restoring both function and aesthetics.

Frequently asked questions

How disruptive is a full pipe replacement?

It depends on location, access, and ground conditions. We plan to minimise disruption — often working in phases, isolating sections, protecting adjacent finishes, and coordinating reinstatement efficiently. For driveways or hard landscaping, careful reseeding or re-paving is done to match original look.

How long does a pipe replacement take?

For typical domestic drains (10–30 metres), replacement including excavation, install, testing, and reinstatement often completes in 1–3 days, depending on soil, depth, and access. Larger or complex runs will require more time.

Is CCTV inspection necessary after installation?

Yes — we always perform a final CCTV pass or pressure test to ensure joints, alignment, and flow are perfect. This verifies that the new installation meets your expectations and operational standards.

Do you replace pipework under structures or hardscape (driveways, patios)?

Absolutely. We use trenching, precise excavation, backfill and compaction strategies to protect foundations. In constrained sites we may adopt sectional replacement, casing, or mini-excavation techniques to preserve the structure above.

Will my drainage connection to public sewer require liaison?

If your replacement affects a shared or adoptable drain, or ties into a public sewer, we’ll manage the necessary liaison, approvals, and connection works on your behalf — including public notices or permissions where needed.

Can replacement pipes be future-proofed?

Yes — we often install pipes with future CCTV access, increased diameter, smooth liners, and materials resistant to roots or corrosion. These “upgrade-as-we-replace” strategies help protect against future failure.
