Blocked drains in Putney: the usual causes
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.
Blockages are cumulative. A slightly displaced joint or a bend with a shallow fall collects debris, the passage narrows, and eventually a single load of washing or a heavy shower is enough to tip it over.
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.
How we deal with blocked drains in Putney
We diagnose before we jet, because the wrong pressure in the wrong place moves the problem rather than solving it.
- Lift and inspect the chambers along the run to establish where the flow stops
- Confirm whether the fault sits inside the property boundary or on a shared or public sewer
- Clear the restriction with high-pressure water jetting at a pressure suited to the pipe
- Flush the run through and check the flow from every connected fitting
- Camera the cleared section where the cause is not obvious, so you know the condition of the pipe
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
- Water standing in an outside gully or rising from an inspection chamber
- Several fittings draining slowly at the same time, rather than just one
- Gurgling from a toilet or sink when a different appliance empties
- A drain smell outside that gets worse after rain or in warm weather
- Water backing up into a shower tray or bath at ground level
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
Our vans carry high-pressure jetting equipment with a range of nozzles, mechanical clearance rods for the situations where jetting is the wrong tool, and a camera with a locator so we can put a mark on the ground above a defect. Choosing between them matters: old clay pipework needs a different pressure from modern plastic, and a nozzle that clears a silted gully can damage a pipe that has already failed.
Once the line is clear we run water through it from every connected fitting rather than declaring the job done at the chamber. If the cause is not obvious, we say so and recommend a survey instead of guessing. You get a plain description of what we found, and if the pipe has an underlying fault you will hear about it from us before it becomes another call-out.
What blocked drains cost in Putney
Outside drain clearance is a fixed £144 plus VAT, with no call-out charge. We confirm the figure before any work starts, so nothing changes once the engineer is on site in Putney.
Areas we cover around Putney
Our Putney work covers SW15 and the rest of Wandsworth. Engineers are usually 60 to 90 minutes away, and because we also cover Barnes, Wandsworth, Fulham and Richmond, a job that crosses a boundary does not need a second contractor.
