Internal drain unblocking covers blockages inside your home — kitchen sinks, basins, baths, showers, toilets, and utility room drains. Everyday things cause most of these blockages: hair, soap, food waste, grease, and wet wipes. Since internal pipes run through walls and under floors, finding the blockage isn't always simple without the right kit.
Ask your engineer whether hand rods, powered drain snakes, micro-jetting, or a camera survey suits your blockage. We work carefully inside your home, and we protect floors and surfaces throughout.
Most internal blockages clear within 30 minutes to an hour. The affected fixtures then go straight back into use.
We check which fixtures struggle to work out where the blockage sits. This tells us whether it's a single trap or a shared pipe run serving several appliances.
We use drain rods, a powered snake, or micro-jetting to clear the obstruction from the waste pipe. Since traps sit directly beneath fixtures, we sometimes remove and clean the trap assembly too.
We flush the cleared pipe with running water from every connected fixture at once. Since this shows up any weak spots straight away, it confirms no secondary blockage remains further along the run.
We refit any access panels or traps and wipe down surfaces before we finish. We also check every connected fixture is draining freely.
The cost of internal drain unblocking depends on whether it's a simple single-fixture blockage or a shared pipe run, since a shared run sometimes needs camera investigation to trace.

When more than one fixture blocks at the same time, the obstruction is almost certainly in a shared waste pipe or the underground drainage rather than in individual traps. This is common in older properties, since multiple fixtures often connect to a single pipe run before it exits the building.
Yes. A blocked internal drain can cause water to leak from pipe joints, overflow from waste traps, or back up through fixtures. Slow leaks can damage plaster, flooring, and joinery over time, so fixing a blockage early limits the risk.
In most cases, no. We reach internal drainage through points that already exist — trap fittings, clean-out plugs, and outside inspection chambers. On the rare occasion a pipe is hard to reach, we talk through the options with you first.
