Collapsed Drain Repair
Recurring blockages, sinkholes or sewage backing up can signal a collapsed drain. We confirm it, locate it precisely, and fix it.
What is a collapsed drain repair?
Collapsed drain repair restores a drain that has broken or caved in. First, we confirm and locate the collapse on camera. We then repair it by relining where the pipe profile allows, or by a targeted excavation and replacement of just the failed section.
A collapsed drain is one of the more serious drainage faults, and a common cause of persistent blockages, foul smells, damp and even subsidence or sinkholes. Because the signs are easy to misread, the first step is always to confirm and locate the collapse on camera.
Depending on the extent and location, we repair by relining where the pipe profile allows. As a result, we can often avoid excavation, or keep any digging to the failed section only.
When you need a collapsed drain repair
- Blockages that keep returning despite clearing
- Sewage or waste water backing up into the property
- A sinkhole, dip or subsidence above the drain run
- Damp, foul smells or rats around the drains
- Several fixtures draining slowly at the same time
Why it matters
Accurate location
We pinpoint exactly where the collapse is, so any excavation stays minimal and targeted. As a result, we never dig up more of your property than the repair needs.
Right method
We reline where possible and excavate only where necessary, so there is no over-digging. Because we match the method to the fault, you get the least disruptive fix that works.
Address the cause
Collapses often follow root damage or age, so we fix the failed section and advise on the rest. Consequently, you deal with the real problem, not just today's symptom.
What's included
- A camera survey to confirm and rule out a simple blockage
- Precise location and depth of the collapse, traced from the surface
- Repair by relining or a targeted excavation and replacement
- A post-repair camera check to confirm the run is restored
- A report you can use for an insurance claim if relevant
How it works
- 01
Confirm on camera
First, a survey confirms the collapse and rules out a simple blockage. Because the signs are easy to misread, this step prevents unnecessary digging.
- 02
Locate precisely
Next, we trace and mark the exact position and depth from the surface. Meanwhile, we work out whether the section can be relined.
- 03
Repair
Finally, relining or a targeted excavation and replacement restores the run. You then get a camera check confirming the drain is sound again.
How much does a collapsed drain repair cost?
The cost of a collapsed drain repair depends on whether the pipe can be relined or must be excavated, and on the depth and length of the failed section. We confirm the extent on camera and give you a fixed price before any work begins.
What affects the price
- Whether the pipe can be relined or must be excavated
- The depth of the pipe and what is above it
- The length of the failed section
- Access and any surface that must be reinstated

Collapsed Drain Repair — your questions answered
How much does it cost to repair a collapsed drain?
It depends on whether the pipe can be relined or must be excavated, and on the depth and length of the failed section. We confirm the extent on camera and give you a fixed price before any work begins.
How do I know if my drain has collapsed?
Common signs are repeated blockages, slow drainage, foul smells, damp patches and, in severe cases, subsidence or a sinkhole. However, only a camera survey confirms it for certain.
Does buildings insurance cover a collapsed drain?
Sometimes. Because many policies cover accidental damage, subsidence or collapse of private drains, it is worth checking yours. We provide a coded survey and report you can submit with a claim.
Will you have to dig?
Not always. A partial collapse can sometimes be relined, whereas a full collapse usually needs a targeted excavation of the failed section only. Either way, we never dig more than necessary.
