Blocked Drain Clearing

Overflowing manholes, backed-up gullies and blocked main drains cleared — usually the same day, and usually on the first visit. Fixed price agreed before anything starts.

Before You Call

Is It the Main Drain or Internal Pipework?

Thirty seconds on this saves you a wasted visit from the wrong trade.

That's the main drain — call us

  • An outside gully, grid or manhole is overflowing or standing full
  • Several fixtures affected at once — toilet, shower and sink together
  • Flushing the toilet makes water rise in the bath or shower
  • Sewage smell outside, or water pooling in the garden

That's a plumber's job

  • One sink draining slowly, everything else fine
  • A single blocked toilet while other fixtures work
  • Leaks under sinks, taps, washing machines
  • Internal pipework with everything outside running clear

If it turns out to be internal, we'll tell you — and you won't be charged for the visit.

Not sure?

Run the kitchen tap for a minute and watch the outside drains. If water backs up anywhere it shouldn't, or an outside gully rises, that's the main drain.

Still unsure? Call and describe it. We'd rather spend two minutes on the phone than send you the wrong trade.

Common Causes

What Actually Blocks a Drain

Fat, oil and grease

Cools, hardens and coats the pipe wall until the bore narrows and everything else catches on it. The single most common cause in drains serving flats and converted houses.

Wet wipes

"Flushable" wipes don't break down. They snag on any imperfection and build into a mass — a particular problem where one drain serves several households.

Root ingress

Roots find hairline cracks and old clay joints, grow into the pipe and trap everything passing through. Jetting clears them; only repair stops them returning.

Silt and ground material

Where a pipe has cracked, soil and sand wash in and build up slowly. The sign is a drain that clears easily then blocks again months later.

Collapsed pipework

Old clay and pitch-fibre drains crack, sag and lose alignment. Debris catches at the fault every time — clearing is temporary, repair is the fix.

Leaves and grit

Gullies and yard grids silt up, especially in autumn. Often the quickest and cheapest of the lot, sometimes sorted on the spot.

FAQs

Common Questions

How much does it cost to unblock a drain?

It depends where the blockage is, what is causing it and how long it takes to clear. That is why we do not quote a figure on the phone and change it on the driveway. The engineer confirms a fixed price on site before starting, and there is no charge if you decide not to proceed.

Should I try rods or chemicals first?

Rods are fine for a gully you can reach. In the main drain they often push the blockage further along or dislodge a joint. Chemical unblockers rarely clear a main-drain blockage and make the work hazardous for whoever comes next.

How long does it take?

Most straightforward blockages are cleared within an hour or two. Where the cause is root ingress or a collapsed section, clearing restores flow but a survey will tell you what needs doing to stop it recurring.

Will you make a mess?

Drainage work is not clean, but clearing up is part of the job rather than an extra. We wash down afterwards and reseat covers properly.

Is the blockage my responsibility?

Drains within your boundary serving only your property are generally yours. Shared drains and sewers beyond the boundary are usually the water company's. We check and tell you which applies, including when it means you should not be paying us.
