If you have a blocked drain in SW20, we are typically 60 to 90 minutes away. We attend jobs throughout Raynes Park and West Wimbledon and everything nearby, 24 hours a day, 365 days a year.

What we cover in SW20

SW20 covers Raynes Park and West Wimbledon, inside Merton. Homes, flats and commercial premises are all covered, whatever the size of the job.

Raynes Park and West Wimbledon are largely interwar semi-detached housing with off-street parking and side access. Soakaways paved over during driveway work are a frequent cause of surface water problems.

Common causes in SW20

What actually causes most of the work in SW20 follow a pattern:

  • Grease from the kitchen, which cools and hardens inside the pipe
  • Cleaning wipes, which hold together all the way to the sewer
  • Tree and shrub roots working into the pipe
  • Silt and grit collecting in a low point

Signs worth reporting

The signs that bring people to call us in SW20:

  • Standing water in a yard gully hours after the last discharge
  • Several fittings draining slowly at once, rather than a single sink
  • Bubbling in the pan when the bath is let out
  • A sour smell near the gully that is stronger in warm weather

How the visit works

The process is the same whatever the address, which is how we can quote a fixed price:

  1. Work through the inspection chambers to find where the flow stops
  2. Work out which side of the boundary the fault sits
  3. Jet the restriction out 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:

  • Hold off on taps, showers and appliances, especially washing machines
  • Move children and pets away from the affected area
  • Move bins or planters off the inspection covers
  • Have your postcode and a description ready so we arrive prepared

Who pays for the repair

A blockage is not automatically your bill. Since 2011, most shared drains and lateral drains in England belong to the water company, so a fault out in the road is not yours to fund. We identify the location and are straight with you about it, even when that means we are not the ones doing the repair.

What it costs in SW20

Outside drain clearance is a fixed £144 plus VAT. We quote a fixed price, not a rate, so a difficult job in SW20 does not become an expensive surprise.

Frequently asked

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.

Yes. We work with restaurants, offices, retail and managed buildings, and we can attend outside trading hours where closing during the day is not practical.

Always, and before any work begins. We quote a fixed figure rather than an hourly rate, so a difficult job does not become an open-ended bill.
