Internal drain unblocking clears blockages inside your home — in sinks, basins, baths, showers, toilets, and laundry drains. Hair, soap, food waste, grease, and wet wipes build up inside the pipes over time. Because these pipes run through walls, floors, and behind fixtures, finding the blockage takes the right tools. We use hand rods, powered drain snakes with swap-in heads, micro-jetting for narrow pipes, and compact CCTV cameras. We work with care around your home and protect floors and surfaces as we go. Most blockages clear within 30 minutes to an hour, and we tidy up before we leave.
We check which fixtures show the problem. This tells us whether the blockage sits in one trap or a shared pipe section.
We clear the blockage with drain rods, a powered snake, or micro-jetting. For a trap right beneath a fixture, we may remove and clean it directly, although this takes extra time.
We flush the cleared pipe with water from every connected fixture at once. This confirms no blockage remains further along.
We put access panels back and wipe down surfaces. We still check every fixture drains well before we finish.
The cost of internal drain unblocking depends on the type of blockage, since some are quicker to reach than others. A single blocked sink trap is usually the quickest fix. A blockage in a shared pipe run, or one that needs a camera, takes more work. Request a fixed-price quote online — we always confirm the price first, with no call-out fee.
When more than one fixture blocks at once, the blockage is almost always in a shared pipe. It sits in the underground drain, not in the individual traps. This is common in older homes, where several fixtures join a single pipe before it leaves the building.
Yes. A blocked internal drain can leak at pipe joints, overflow from waste traps, or back up through your fixtures. Ongoing damp from a slow leak can damage plaster, flooring, and woodwork. Fixing a blockage early lowers the risk, since damp damage often costs more to repair than the blockage itself.
In most cases, no. We reach internal drains through existing access points — trap fittings, clean-out plugs, and outside inspection chambers. On the rare occasion a pipe is fully out of reach, we'll talk through the options with you first.
