Drain Repairs

A cracked, root-damaged or collapsed drain needs the right repair, not the biggest one. We survey it first, then line it, dig it or fix the fitting, across Surrey, Sussex, Kent, Hampshire and London.

The basics

How do you choose the right drain repair?

The repair depends on what is wrong with the pipe, and you can’t tell that from the surface. A CCTV drain survey shows the damage, where it is and how far it runs, and that decides the repair.

If the pipe is still in line and the damage is cracks, roots or minor joint movement, drain lining can often repair it without digging. If it has collapsed, sunk or been badly displaced, excavation and replacement is the proper fix.

Damage at a chamber is a different job. We deal with that under manhole repairs and installations, and roots are cleared with root cutting before any repair is chosen.

Not sure the drain is yours to repair? Our guide to drain and sewer responsibility explains who looks after what.

How it works

From first call to finished repair

  1. Survey the drain

    We jet where needed so the camera can see the pipe, then survey it.

  2. Explain what we found

    We tell you what is wrong in plain English and what the realistic options are.

  3. Agree the repair

    Lining, excavation or a fitting repair, with a timescale and quote.

  4. Carry out the repair

    The damaged pipe is lined or replaced and the ground reinstated where we have dug.

  5. Check the result

    We run a final camera check so you can see the drain is sound.

Why act

Don’t wait for a damaged drain to get worse

A broken drain rarely mends itself. Waste leaks into the ground, roots follow it in and the damage spreads along the pipe.

A repair done early is usually smaller than one done after the ground has washed away or the drain has collapsed.

Signs your drain may need repair

  • Blockages that keep coming back in the same place
  • Smells around the drain or garden
  • Damp patches or ground that is sinking
  • Rats around the property
  • Slow drains throughout the house

Questions answered

Drain repair FAQs

Do I need a survey before a drain repair?

In almost every case, yes. A CCTV survey shows what is wrong and where, so the repair matches the damage instead of being guessed.

Can every damaged drain be lined?

No. Cracks, root damage and small movement at joints can often be lined. A collapsed, crushed or badly displaced pipe usually has to be dug out and replaced.

Who is responsible for a damaged drain?

It depends where the damage is. Drains that serve only your property are usually yours to maintain. Shared drains and pipes outside the boundary have been the water company’s responsibility since October 2011. Our responsibility guide explains the detail.

Is a damaged drain always an emergency?

Not always, but it should not be left. A collapsed or leaking drain gets worse over time, and a survey shows what can be planned and what cannot wait.

Do you repair drains at businesses as well as homes?

Yes. We work for homeowners, hotels, pubs, restaurants and other commercial sites.
