The issue on this job
The occupier had recurring smells and periodic slow discharge, but there was no room for open excavation through the shared hallway route. CCTV footage showed cracking and minor displacement rather than a full collapse, which made trenchless repair the practical option.
Because the run served multiple parts of the conversion, the work had to be staged around access for other residents and kept clean through a narrow internal route.
How we handled it
We cleaned the line, trimmed the defective section back to sound pipe, and carried out drain relining in Richmond with a short liner sized to the cracked branch rather than lining the full run unnecessarily.
The liner installation was completed from existing access points, which avoided opening floors or disturbing the neighbouring property boundary line.
What the result was
Output
First-visit diagnosis and repair outcome
Delivery
Kept the programme moving
Programme
half a day on site
Odours stopped once the branch was sealed, and the client kept the original finishes intact. The final survey showed a continuous internal surface through the repaired section without the disruption that excavation would have caused.
If you are dealing with repeated foul smells from a cracked branch drain on a basement flat in a richmond conversion, the next step is a clear scope and quote.

This type of work is usually needed where the pipe is still structurally open but cracking, displaced joints, or root ingress keep causing repeat symptoms. It is especially useful when the affected run sits beneath finished floors or shared areas.
