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 Isleworth
- 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 Isleworth
Georgian riverside lanes and big new riverside developments, sharing very different pipes.
Isleworth is two centuries of drainage in one postcode. Old Isleworth, the lanes around the church and the London Apprentice, is genuinely historic: Georgian and Victorian buildings on narrow, eccentric drain runs, some routed in ways that only make sense if you know where the wharves and orchards used to be. The camera goes down an Old Isleworth drain and finds brickwork older than the borough. We love it here. The drains have stories.
New Isleworth is the other end of the timeline: the big riverside and hospital-quarter developments have brought thousands of modern flats, all pumping into communal stacks and new adopted sewers. Modern pipe, modern problems: wet wipes at apartment-block scale, and communal runs where one floor’s habits become five floors’ blockage. Management companies of TW7, we do surveys, planned jetting and honest reports, and we turn up when the residents’ group chat is already on fire.
In between sit the Victorian terraces off the Twickenham Road and the interwar streets towards Osterley, with the Duke of Northumberland’s River keeping the water table lively on its way to the Thames. Whichever Isleworth you live in, TW7 is covered 24/7, and the person answering actually knows where Mill Plat is.
We cover all of Isleworth (TW7) — from Old Isleworth, Syon Park, the Duke of Northumberland's River and across Brentford, Hounslow, Twickenham. Being genuinely local means we already know what Isleworth's drains are made of, and how fast we can be at your door.More about drains in Isleworth →
