Internal drain unblocking deals with blocks in the waste pipes inside your property. This covers kitchen sinks, bathroom basins, baths, showers, toilets and utility room drains. It runs up to the point where they leave the building for the underground drains. Everyday things cause these blocks. They include hair, soap, food waste, grease, sanitary products and wet wipes that build up inside traps and pipes.
Internal pipes run through walls, under floors and behind fixtures. Because of this, blocks are not always easy to find without specialist tools. Our engineers carry a full range of drain clearing tools. These include hand rods and powered drain snakes with interchangeable cutting heads. They also include micro-jetting units for smaller pipes and compact CCTV cameras for pipe inspection.
We work carefully inside your home. We protect floors and surfaces, and we always clean up after ourselves. Most internal blocks clear within 30 minutes to one hour. This restores full use of the fixtures.
We check which fixtures show symptoms. This shows if the block is in a single trap or in a shared pipe section that serves several appliances.
We use drain rods, a powered snake or micro-jetting to clear the block from the waste pipe. For traps directly under fixtures, we may remove and clean the trap.
We run water from all connected fixtures at the same time to flush the cleared pipe. This confirms no secondary blocks exist further along the run.
We refit any access panels or traps and wipe down surfaces. Before we finish, we check that each connected fixture drains freely.
The cost of internal drain unblocking depends on the type of blockage. Simple single-fixture problems, such as a clogged sink trap, are usually quicker to fix. Blocks in shared pipe runs take longer, while those that need camera investigation take longer still. Request a fast, fixed-price quote online. We always confirm the price before we begin and never charge a call-out fee.
When more than one fixture blocks at once, the block is almost certainly in a shared waste pipe or the underground drains. It is rarely in the individual traps. This is common in older properties, because several fixtures often join a single pipe run before it leaves the building.
Yes. A blocked internal drain can make water leak from pipe joints, overflow from waste traps or back up through fixtures. Slow leaks that keep things damp can harm plaster, flooring and joinery. Because of this, fixing blocks promptly lowers the risk of secondary water damage.
In most cases, no. We reach internal drains through existing access points. These include trap fittings you can remove, clean-out plugs and external inspection chambers. Rarely, pipes are completely inaccessible. However, we then discuss access options with you before we go ahead.
