We are a family-run firm covering London since 2013, and SW19 is well within our patch. The postcode takes in Wimbledon and Merton.

What we cover in SW19

SW19 covers Wimbledon and Merton, inside Merton. Homes, flats and commercial premises are all covered, from single blockages to full drainage installations.

Wimbledon splits between the village, with large period houses and mature gardens, and the town, with terraces and interwar semis. Clay subsoil moving seasonally opens joints in rigid older pipework.

Common causes in SW19

The causes we see most often in SW19 follow a pattern:

  • Cooking fat washed into the kitchen waste, which solidifies as soon as it cools
  • Cleaning wipes, which stay intact in the drain
  • Roots from nearby planting working into the pipe
  • Soil and grit collecting in a low point

Signs worth reporting

The symptoms worth reporting when you ring:

  • Standing water in a yard gully long after use
  • Two or more fittings affected together, which points at the shared run
  • A glugging noise from a plughole when something else empties
  • A sour smell near the gully that keeps coming back

How the visit works

Finding the cause comes before clearing it:

  1. Check the chambers along the run to find where the flow stops
  2. Establish whether it is your pipe or the water company’s
  3. Clear it with high-pressure jetting at a pressure suited to the pipe
  4. Prove the flow from every connected appliance before we finish

Before we arrive

Worth doing while you wait:

  • Keep water use to nothing, especially washing machines
  • Move children and pets away from the affected area
  • Move bins or planters off the inspection covers
  • Jot down what is draining and what is not so we arrive prepared

Who pays for the repair

Whose pipe it is matters as much as what is in it. Most pipework beyond your boundary became the water company’s responsibility in 2011, so a fault out in the road is not yours to fund. We work out where the fault is and say so, even where it means there is no job in it for us.

What it costs in SW19

Outside drain clearance is a fixed £144 plus VAT. There is no call-out charge in SW19, at any hour. You get the figure before any work begins.

Frequently asked

No. We never charge a call-out fee, at any hour, on any day of the year. You get a fixed price for the work itself before anything starts.

Yes. We run a genuine 24/7 emergency service, 365 days a year, including bank holidays.

Shared drains and public sewers are usually the water company's responsibility rather than yours. We identify where the fault sits and tell you plainly, so you are not paying for someone else's pipe.
