What causes blocked sinks in Richmond
Richmond has Georgian and Victorian houses near the green and the river, Edwardian and interwar homes further out, and a good number of period conversions. Gardens are generally mature, with established trees close to boundary drain runs.
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.
Two factors dominate here: root ingress from mature trees into older clay joints, and tidal flooding along the lower riverside streets, which pushes water back through surface drains during high spring tides.
What happens when we attend in Richmond
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 listed frontages need a careful approach when covers are lifted or excavation is considered. Trenchless repair is often the sensible route because it avoids disturbing driveways and mature planting.
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 Richmond
- Root ingress from mature trees into open clay joints
- Tidal water pushing back through surface drains on the lowest streets
- Displaced sections under driveways and established planting
Richmond is period property with mature gardens, and much of our work here starts with a survey rather than a jetting hose. Trenchless repair suits this area particularly well, because excavation under an established garden or a listed frontage is the expensive part.
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 Richmond
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 Richmond does not become an open-ended one.
Areas we cover around Richmond
We cover TW9, TW10 and TW1 and the surrounding streets of Richmond upon Thames, with engineers typically 60 to 90 minutes from the door. We work across Barnes, Putney, Wimbledon and Merton 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.
