The High Street is one of the best places to eat in south-west London and its kitchens send a serious grease load down small Victorian and interwar pipes. Planned jetting on a restaurant run is the difference between a Tuesday morning visit and a Friday night closure.
High-pressure water jetting is the most satisfying thing we do, and given how much we enjoy the rest of the job, that’s a serious claim. A jetting nozzle runs at up to 3,000 psi and doesn’t just punch a hole through a blockage the way a rod does. It strips the pipe wall back to bare clay or plastic: grease, soap scale, root fibres, the lot, flushed out and gone.
Think of rodding as squeezing past the fatberg and jetting as evicting it.
When jetting is the right call:
- Grease and fat build-up in kitchen runs. This is most TW blockages. Grease doesn’t block a pipe overnight; it narrows it for years, and jetting resets the clock to day one.
- Root ingress. Fine roots from street trees and mature gardens find their way into pipe joints (a speciality of the leafier TW streets). Jetting cuts them back cleanly. If they’ve cracked the pipe, we’ll show you on camera and talk repair options honestly.
- Recurring blockages. If you’re on first-name terms with a plunger, the pipe is narrowed somewhere. One proper jet is cheaper than four call-outs.
- Scale in older pipes. Hard south-west London water leaves limescale in cast iron and clay runs. Jetting removes it without digging anything up.
What it costs: typical domestic jetting in the TW area runs £150–£300 depending on the length and state of the run. Price agreed up front, before the van door even opens. If a blockage clears with simpler kit, we use the simpler kit and charge for that instead.
What to do right now in New Malden
- If the drain is completely blocked and backing up, stop adding water and call us. Jetting is usually how we'll clear it.
- Recurring slow drains are the classic sign a pipe needs jetting rather than another bottle of one-shot unblocker.
- Don't rent a pressure washer and improvise. Domestic washers can't reach the blockage and the wrong nozzle can damage older pipes.
Drain Jetting help, local to New Malden
Interwar suburb on the Beverley Brook: long 1930s runs, a brook that backs up in storms, and grease from one of London's best restaurant streets.
New Malden, KT3, is interwar London at its most complete: street after street of 1930s semis between Kingston Road and the Beverley Brook, with a High Street that has become one of the best places to eat in south-west London. Both facts matter underground.
The semis have long garden runs with a gentle fall towards the brook, and the brook itself is the local wildcard. After heavy rain it runs high, the surface water system backs up, and gullies that are perfectly clear overflow because the water has nowhere to go. We get a lot of storm calls here and the honest answer is sometimes that the drain is fine and the brook is full. We would rather tell you that than clear a clear pipe and charge for it.
The High Street is a grease story. Dozens of kitchens on small, old pipes produce fatbergs that we find professionally fascinating and restaurateurs find expensive, and a planned jetting schedule beats a Friday-night flood every time. We cover New Malden, Old Malden and Coombe at any hour from the Kingston side.
