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 Isleworth

  1. Stop running water into the affected drain, sink or toilet. Every litre you add has nowhere to go.
  2. If an outside gully is overflowing, keep children and pets away from the standing water.
  3. 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.
  4. 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 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 →

Blocked Drain in Isleworth: your questions

How much does it cost to unblock a drain in Isleworth?

Most blocked drains in Isleworth come in between £90 and £180, and out-of-hours visits run £150 to £250. You get the price agreed on the phone or at the door before anything starts, and it does not change when we are covered in the evidence. If it turns out to be Thames Water's responsibility, we will tell you and you will not be charged for us saying so.

How quickly can you get to a blocked drain in Isleworth?

Typically 60–90 min across Isleworth and the wider TW area, 24 hours a day. When you call, a real person picks up and gives you an honest ETA for your actual street rather than a national average. If something needs doing before we arrive, like stopping water going into the drain, we will talk you through it on the phone.

What actually happens when you arrive?

We find the blockage before we touch anything, usually by lifting the nearest inspection chamber to see which way the water is standing. That tells us whether the problem is in your pipe or the shared run. Then we clear it at the source with rods or a jetting lance, run water through to prove it is genuinely gone, and put your covers and flowerpots back where we found them.

Why does my drain keep blocking?

A drain that re-blocks within weeks is telling you something structural is wrong, not that it needs clearing more often. The usual causes are tree roots that have found a joint, a cracked or dropped section collecting debris, or years of grease narrowing the pipe. A camera survey finds the actual cause so you stop paying to treat the symptom.

Is the blocked drain my responsibility or Thames Water's?

Roughly: pipes inside your boundary serving only your home are yours, and shared drains or sewers beyond the boundary are usually Thames Water's. The quickest tell is where it is overflowing and whether your neighbours have the same problem. We will say honestly on the phone if it sounds like their job, because a free fix for you is a fair answer from us.

Do you cover Isleworth?

Yes, all of TW7, 24 hours a day, from Old Isleworth and Syon Park across to the hospital quarter and the Osterley side. The person answering actually knows where Mill Plat is.

Why are Old Isleworth drains so unpredictable?

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 and finds brickwork older than the borough. Guessing does not work here; looking does.

I'm in a new riverside flat. Why does the blockage keep coming back?

The riverside and hospital-quarter developments pump into communal stacks, which means wet wipes at apartment-block scale and one floor's habits becoming five floors' blockage. Clearing it fixes today; it comes back because the cause is upstream of you. Blocks like these need planned jetting and a survey rather than repeat emergency call-outs.
