If you have a drain blockage in SE21, we can usually be with you inside 90 minutes. We attend jobs throughout Dulwich and Tulse Hill and everything nearby, day and night, including weekends and bank holidays.

What we cover in SE21

SE21 covers Dulwich and Tulse Hill, inside Southwark and Lambeth. We work for householders and businesses alike in this area, whatever the size of the job.

Dulwich has large Victorian and Edwardian villas, generous gardens and heavy tree cover on clay subsoil. Roots entering open clay joints, and seasonal movement opening those joints further, are the defining faults.

Common causes in SE21

The bulk of the jobs in SE21 comes down to a short list:

  • A build-up that has been narrowing the pipe for a while, tipped over by a single wash
  • A cracked or displaced section catching debris every time
  • A common drain serving more than one home
  • Surface water overwhelming a combined sewer

Signs worth reporting

What tends to prompt the call around SE21:

  • Water standing in an outside gully hours after the last discharge
  • Several fittings draining slowly at once, rather than a single sink
  • A glugging noise from a plughole when something else empties
  • A sour smell near the gully that worsens after rain

How the visit works

The order matters, so we work it out before we jet:

  1. Make the property safe on arrival
  2. Find where the flow stops by working through the chambers
  3. Clear it by jetting or mechanically
  4. Report what caused it and whether the pipe needs more than clearing

Before we arrive

Worth doing while you wait:

  • Stop using water in the property, including the washing machine and dishwasher
  • Move children and pets away from the affected area
  • Move bins or planters off the inspection covers
  • Note which fittings are affected so we arrive prepared

Who pays for the repair

Before anyone invoices you, it is worth knowing where the fault sits. Pipework inside your boundary serving only your property is yours; shared runs and anything past the boundary generally are not. We record it so you have something to act on.

What it costs in SE21

Drain unblocking starts at a fixed £120 plus VAT, with no call-out charge at any hour. Prices are fixed rather than hourly, so nothing changes once we are on site.
