Two things block Hounslow drains: density and grease. Houses split into flats put three kitchens on a run designed for one, and the shared pipework behind the High Street parades collects fat from the commercial kitchens above it. If you are behind or above a takeaway, the blockage probably did not start with you.
A blocked drain never fixes itself. It builds. Grease, wipes, roots and forty years of “it’ll be fine” collect in the pipe until one morning the shower is ankle-deep and the kitchen smells like something died under the floor.
Here’s the part we should probably keep to ourselves: we find blockages genuinely interesting. Every blocked drain is a little mystery. Is it a fatberg? Tree roots that found a joint in a Victorian clay pipe? A toy dinosaur? (Real find. His name is Trevor now.) The point is, the job everyone else dreads is the one we turn up excited about, with the right kit to solve it first visit.
We clear the blockage at its source, not just poke it further down the pipe to become next month’s call-out. If more than one drain is backing up at once, that usually points to the main run between your house and the sewer, and we handle that too.
What it costs: most straightforward domestic blockages in the TW area run £90–£180, rising to £150–£250 for middle-of-the-night call-outs. You get a price on the phone or at the door before any work starts, and it doesn’t change when we’re covered in the evidence.
One honest note: standing water from a blocked drain is a health hazard, and foul water backing up indoors can damage floors and walls quickly. The sooner it’s cleared, the smaller the bill. Day or night, we answer.
What to do right now in Hounslow
- Stop running water into the affected drain, sink or toilet. Every litre you add has nowhere to go.
- If an outside gully is overflowing, keep children and pets away from the standing water.
- Don't pour chemical unblocker into a fully blocked drain. It sits in the pipe, and whoever clears it (us, happily) gets a face full of it.
- Call us. We'll give you an honest ETA and talk you through anything urgent while we're on the way.
Blocked Drain 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 →
