New Malden's 1930s streets have long garden runs with a gentle fall towards the Beverley Brook, and when the brook is high after a storm the surface water system backs up into them. A gully that overflows only in heavy rain is usually telling you about the brook, and we will say so rather than invoice for a drain that is clear.
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 New Malden
- 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 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.
We cover all of New Malden (KT3) — from the High Street, New Malden station, Beverley Brook and across Kingston upon Thames, Raynes Park, Worcester Park. Being genuinely local means we already know what New Malden's drains are made of, and how fast we can be at your door.More about drains in New Malden →
