What causes blocked sinks in Greenwich
Greenwich combines Georgian and early Victorian terraces near the town centre, larger detached and semi-detached homes towards Blackheath, and newer riverside flats along the Thames. Older properties frequently retain their original below-ground clay pipework.
Kitchen sinks block because fat cools in the pipe. It goes down warm and liquid, then sets on the pipe wall and gathers coffee grounds, food waste and detergent residue until the passage closes.
The riverside is tidal and parts of the borough fall steeply from the heath, so surface water arrives fast and finds any weak point in a drain run. Older clay joints, root ingress from mature street trees and displaced sections are the faults we see most often.
What happens when we attend in Greenwich
We clear the trap first, then confirm the waste run beyond it is actually moving.
- Isolate and clear the trap under the sink, protecting the unit below
- Clear the waste run to the point where it joins the stack or gully
- Where the run is shared with other fittings, check those as well
- Flush the line through with volume, not just enough to drain the bowl
- Advise on what caused the build-up so it can be avoided next time
Conservation areas and cobbled or stone-set frontages need care when covers are lifted. We work around that rather than forcing access, and we reinstate what we move.
Signs it needs attention now
- Water rising in the bowl before it drains away
- A gurgle from the plughole after the water has gone
- A stale smell from the plughole, particularly in a kitchen
- Both sides of a double sink draining slowly
- Water appearing under the unit or at the trap
What we see most often in Greenwich
- Root ingress from mature street trees into older clay pipework
- Displaced joints caused by ground movement on the slopes towards the heath
- Surface water arriving faster than gullies can take it after heavy rain
In Greenwich we work for owners of period houses, for buyers commissioning a survey before completion, and for the managed blocks along the riverside. Conservation-area properties need a careful approach, and we plan for that rather than improvising on the day.
Equipment and what happens afterwards
For sink work we carry small-bore clearance equipment, hand tools for traps and waste fittings, and jetting for the section beyond where hand tools reach. We also carry replacement trap seals and connectors, because a trap that has been disturbed several times over the years often needs replacing rather than refitting.
After clearing we fill and drain the bowl fully rather than running a trickle, which is the only reliable way to see whether the restriction has really gone. We check underneath for leaks at the joints we disturbed, and we tell you what the build-up was made of, because that usually points to a simple change in habit that prevents the next one.
What blocked sinks cost in Greenwich
Clearing a blocked sink is a fixed £120 plus VAT, with no call-out charge. You get a fixed price up front rather than an hourly rate, which means a difficult job in Greenwich does not become an open-ended one.
Areas we cover around Greenwich
We cover SE10, SE3, SE7 and SE18 and the surrounding streets of Royal Borough of Greenwich, with engineers typically 60 to 90 minutes from the door. We work across Southwark, Tower Hamlets, Peckham and Dulwich 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.
