Why Dulwich properties get drainage faults
Dulwich has substantial Victorian and Edwardian villas, generous gardens and a strong tree presence, alongside terraces in East Dulwich. Many properties keep their original below-ground pipework because there has been no reason to replace it.
The value of a survey is not the footage itself but what it rules out. Knowing that a pipe is sound saves the cost of excavating it; knowing that it is not saves the cost of clearing it again and again.
Mature trees and clay subsoil are the two dominant factors. Roots find their way into open clay joints in search of moisture, and seasonal ground movement gradually opens those joints further, so problems build slowly over years.
Our approach in Dulwich
The camera goes in after the line is clear enough to read, otherwise the footage shows debris rather than defects.
- Clear enough of the line to give the camera a usable view
- Run the camera through the full length of the affected drain
- Record the position and depth of any defect with a locator above ground
- Grade what we find, from minor wear to a defect needing repair
- Provide the footage and a written summary you can pass to an insurer, surveyor or builder
Larger gardens make excavation possible, but it is rarely the best answer under established planting or a block-paved drive. A survey first usually shows that a lining repair will do the job.
Signs it needs attention now
- A drain that blocks again within weeks of being cleared
- Unexplained damp, subsidence concerns or a sinkhole in the garden
- Buying a property with mature trees close to the drain run
- An insurer or managing agent asking for evidence of the pipe condition
- Planning an extension that will be built over an existing drain
What we see most often in Dulwich
- Roots entering open clay joints under mature planting
- Seasonal clay movement gradually opening joints along a run
- Chambers lost under later landscaping and driveway work
Dulwich work is mostly for owners of larger period houses, and a high proportion of it starts as a survey. Established gardens and block-paved drives make excavation costly, so knowing exactly where a defect sits is worth the survey fee several times over.
Equipment and what happens afterwards
We survey with a self-levelling colour camera and an above-ground locator, which together tell us not just what a defect looks like but exactly where it is and how deep. That matters, because a repair quote based on a rough guess at position is a repair quote that changes once the ground is open.
You receive the footage along with a written summary describing each defect, its position and how serious it is. We write it so that a surveyor, an insurer or a builder can use it directly. Where a repair is needed we set out the realistic options, including the ones that do not involve excavation.
What cctv drain surveys cost in Dulwich

Areas we cover around Dulwich
