What causes damaged drains in Putney
Putney runs from riverside mansion blocks and newer flats up the hill to Victorian and Edwardian terraces and larger detached homes towards the heath. Mansion blocks bring shared stacks and communal drainage into the picture.
Trenchless repair lines the existing pipe from the inside, forming a new wall within the old one. The run stays where it is and the surface above it is left alone.
The lower riverside streets deal with a high water table and tidal influence, so surface water clears more slowly and any restriction shows sooner. Higher up, mature trees and older clay laterals are the more common cause.
What happens when we attend in Putney
The sequence is fixed: see it, clean it, line it, then prove it with a second camera run.
- Survey the run on camera and locate the defect precisely
- Cut out root growth and clean the pipe wall so the liner can bond
- Install a resin liner sized to the pipe and cure it in place
- Reinstate any branch connections that the liner has covered
- Camera the finished repair and provide the footage as a record
In mansion blocks the drainage is communal, so we work with the managing agent and identify which flat the fault relates to. That avoids charging one leaseholder for a building-wide problem.
Signs it needs attention now
- A drain that reblocks repeatedly in the same place
- Roots visible in a chamber or pulled out during clearance
- A camera survey showing a cracked, displaced or deformed section
- Damp or subsidence concerns near a known drain run
- A drain running under a driveway, extension or mature planting
What we see most often in Putney
- Communal stacks in mansion blocks restricted by grease and wipes
- Slow-clearing surface water in the lower riverside streets
- Root ingress into older laterals in the larger gardens towards the heath
Putney work covers riverside mansion blocks with communal drainage, family houses up the hill, and a number of managed developments. In blocks we deal with the managing agent and identify whether the fault is communal before any leaseholder is charged.
Equipment and what happens afterwards
Lining work needs the pipe properly prepared, so we carry root-cutting and cleaning equipment as well as the liners and resin. We size the liner to the pipe rather than the other way round, and we carry the tooling to reinstate branch connections that the liner covers.
Every lining job finishes with a second camera run, and you get that footage as a record of the completed repair. We check that reinstated connections are flowing properly, and we are straightforward about the parts of the run we have not lined, because a repair to one section does not change the condition of the next.
What trenchless drain repairs cost in Putney
Trenchless repairs are quoted after a CCTV survey, because the price depends on the length and condition of the section being lined. There is no call-out charge in Putney, at any hour, and the price you are given on the call is the price you pay.
Areas we cover around Putney
We cover SW15 and the surrounding streets of Wandsworth, with engineers typically 60 to 90 minutes from the door. We work across Barnes, Wandsworth, Fulham and Richmond as well, so if the fault turns out to sit on a run shared with a neighbouring property we can deal with both ends of it.
