Blocked drains, jetting and drain repairs

Generally, you're responsible for drains that serve only your property and sit within its boundary. Pipes shared with neighbours, or that run outside your boundary, are usually the water company's responsibility, which is Thames Water across most of London. We can tell you which applies once we've looked.

Repeat blockages soon after clearing, a constant sewage smell, damp patches, sinking paving or rodents near a drain run all suggest damage. A CCTV drain survey confirms it by showing cracks, displaced joints, root intrusion or collapse, with the exact location so the repair can be targeted.

Yes, when it's done properly. The pressure and nozzle are matched to the pipe's size and condition. If a CCTV survey shows a pipe is already cracked or fragile, we adjust the approach or recommend a repair first, so jetting doesn't make existing damage worse.

Drain smells usually come from food, grease and soap rotting in the pipe, a dried-out trap letting sewer gas through, or a partial blockage. Run water through rarely used fittings to refill their traps. If the smell persists, the drain needs cleaning or there may be a defect.
