A blocked drain doesn't wait for a convenient moment. It backs up on a Sunday evening, or the morning you've got people coming over, or mid-shift at a busy commercial premises near Shannon Corner. When it happens, you need someone who can get there fast and tell you honestly what's wrong.
We cover the whole KT3 area around the clock: Old Malden, Malden Manor, West Barnes, Coombe, Norbiton, Malden Park, Beverley Park and everywhere in between. One call and we'll tell you when we're arriving and what the job will cost before we lift a single cover.
What Counts as Urgent
Not every slow drain needs same-hour attention, but some do. These are the calls we get most often across New Malden:
- Sewage or foul water backing up into a sink, bath or toilet inside the property
- A manhole overflowing onto a driveway in Beverley Park or Coombe Vale
- Complete blockage with no drainage at all in a kitchen or ground-floor bathroom
- A shared drain serving multiple flats in Malden Manor that's brought every unit to a halt
- Flooding outside a commercial unit near Shannon Corner where customers or staff are at risk
Not sure whether yours qualifies? Call us. We'll ask a couple of questions and give you a direct answer.
What Happens When We Arrive
The engineer assesses before anything else. That means lifting the nearest accessible manhole, checking flow and locating where the obstruction sits. Most residential blockages in KT3 are cleared with high-pressure water jetting. Unlike rodding, jetting breaks up and flushes the blockage rather than just piercing it, and on tougher jobs the engineer works upstream to break the material down before flushing it through.
If the drain's been backing up repeatedly, or if jetting doesn't shift it cleanly, we carry CCTV camera equipment on the van. We can run a survey on the same visit to check for a collapsed section, root intrusion or a structural defect that won't resolve with clearance alone. You'll see exactly what we find.
All our engineers are uniformed and fully insured. We operate to Water Jetting Association guidelines, which matters when you've got older clay pipes under a Green Lane or Norbiton garden that won't take excessive pressure.
Why KT3 Drains Block When They Do
New Malden's housing stock creates predictable drainage patterns. Victorian terraces in streets around Malden Park and Old Malden often connect to combined sewers that carry both surface water and foul drainage in the same pipe. When those lines accumulate decades of grease and silt, a single heavy downpour can be enough to tip them over.
Newer builds around Motspur Park and West Barnes have separate systems, but they bring their own problems: smaller-diameter pipes, shared gully runs between properties, and connections that weren't always installed to the standard Thames Water expects.
Roots from the mature trees in Coombe and Beverley Park work into pipe joints quietly over years. You won't notice until flow slows noticeably, then one day nothing moves at all.
Clearance or Repair: Which One Do You Need
Sometimes a drain's just blocked. Jetting clears it and you're done. Other times, jetting reveals a structural problem underneath. Here's how the two differ:
| Situation | What it points to | Likely next step |
|---|---|---|
| Single blockage, drains freely once cleared | Grease, wipes or debris accumulation | Clearance, possibly a maintenance schedule |
| Repeated blockages in the same spot | Root intrusion or partial collapse | CCTV survey, then repair or relining |
| Multiple properties affected at once | Shared main sewer blockage | Clearance plus Thames Water notification if needed |
| Slow drain with surcharging at the manhole | Pipe sag causing pooling and backflow | CCTV survey to confirm before deciding on repair |
If we find structural damage that needs repairing, that work carries Drainsco's own 20-year guarantee. Clearance is a separate job, priced individually and agreed before we start.
