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 Hounslow
- 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 Hounslow
Dense conversions and takeaway-heavy high streets: grease is the number one blocker here.
Hounslow keeps us busier than anywhere else in the TW area, and the reason is simple: density. The 1930s semis of Heston and Lampton have been joined by loft conversions, extensions and houses split into flats, so drain runs designed for one family now serve three kitchens and five bathrooms. A pipe doing triple its design load doesn’t owe anyone an apology when it blocks.
Then there’s the High Street. We say this with love and a jetting lance: Hounslow’s food scene is the best fatberg factory in south-west London. Grease from commercial kitchens cools and sets in shared runs behind the parades, and the domestic drains connected to them inherit the problem. If you’re above or behind a takeaway and your sink has stopped draining, it’s probably not your washing-up. We jet these runs every week and we know exactly what we’ll find.
Out west, Cranford and the TW6 fringe around Heathrow add long postwar estate runs and a lot of hard-working shared drainage. Wherever you are in TW3 to TW6, we cover it 24/7, one number, and the person who turns up will be genuinely enthusiastic about whatever your drain has been hiding.
We cover all of Hounslow (TW3, TW4, TW5, TW6) — from Hounslow High Street, Lampton Park, Osterley Park and across Heston, Cranford, Lampton. Being genuinely local means we already know what Hounslow's drains are made of, and how fast we can be at your door.More about drains in Hounslow →
