Internal drain unblocking clears blockages inside the waste pipes in your property. That covers kitchen sinks, bathroom basins, baths, showers, toilets, and utility room drains, right up to where they leave the building. Everyday things like hair, soap, food waste, grease, sanitary products, and wet wipes cause most internal blockages, building up inside traps and pipes. Since internal pipes run through walls, under floors, and behind fixtures, finding a blockage often needs the right tools. Your engineer carries a full set of internal clearing tools, including hand rods, powered drain snakes with swap-out heads, micro-jetting units for smaller pipes, and compact CCTV cameras. They work carefully inside your home, protect floors and surfaces, and clean up afterwards. Most internal blockages clear within 30 minutes to an hour, and the fixture is back in full use straight away.
We check which fixtures are affected, since that shows whether the blockage sits in a single trap or a shared pipe run serving several fixtures.
We clear the blockage from the waste pipe using drain rods, a powered snake, or micro-jetting. For traps right under a fixture, we may remove and clean the trap itself.
We flush the cleared pipe with water from every connected fixture at once, since that checks for any other blockage further along.
Any access panels or traps are refitted and surfaces wiped down. We still confirm every connected fixture is draining freely before finishing.
The cost of internal drain unblocking depends on the job. A simple single-fixture blockage, like a clogged sink trap, costs less than a shared pipe run that needs a camera check. Request a fast, fixed-price quote online. Since there's no call-out fee, the price is confirmed before work starts.
When more than one fixture blocks at once, the blockage is almost certainly in a shared waste pipe or the underground drainage, since it's unlikely each trap failed separately. This is common in older properties, where several fixtures share one pipe run.
Yes, since a blocked internal drain can cause water to leak from pipe joints, overflow from waste traps, or back up through fixtures. Ongoing damp from slow leaks can damage plaster, floors, and woodwork, so dealing with blockages quickly cuts that risk.
In most cases, no, since we reach internal drainage through existing access points such as removable trap fittings, clean-out plugs, and external inspection chambers. On the rare occasion a pipe is fully out of reach, we talk through access options with you first.
