Blocked drain cleared, and the cause found.
Updated
We clear blocked drains, toilets, sinks and outside gullies, then put a camera down the pipe to show you why it blocked. That way you fix the cause, not just this blockage.

Why blocked drains keep coming back.
Most blockages are caused by what goes down the drain. Fat and cooking oil set hard in a cold pipe. Wet wipes, which are sold as flushable but do not break down like toilet paper, catch on joints and gather everything behind them. Hair and soap build up in shower wastes. Leaves and silt wash into outside gullies.
Some blockages are caused by the pipe itself. Tree roots find their way in through tiny gaps at the joints and grow into a mat that catches waste. Older clay pipes crack and shift. A dip in the pipe lets water sit and debris settle. In many homes built from the 1950s to the 1970s, pitch fibre pipes were used, and these can soften and lose their shape over time.
If a drain blocks once, clearing it is often all it needs. If it blocks again, the cause is usually in the pipe. That is why we follow every clearance with a camera check: you see what caused the blockage and whether the pipe is sound, so you are not paying for the same call-out every few months.
Things to try before you call.
For a slow sink or shower, take out the plug or waste cover and remove any hair or debris you can reach. A plunger can shift a blocked toilet or sink. Pouring very hot, not boiling, water down a greasy kitchen sink sometimes helps. Avoid strong chemical drain cleaners, which can damage older pipes and are dangerous if they splash back.
If more than one fitting is affected, water is rising outside, or you can smell sewage, the blockage is further down the system. That needs clearing from a chamber or gully with proper equipment, so call us rather than keep plunging.
Shared drains and the water company.
If the blockage is in a drain shared with neighbours, or in the sewer beyond your boundary, it is usually the responsibility of your local water company. Our camera survey shows where the blockage is, and the footage gives you something clear to send them.

Call us07888 868356How do I know if my outside drain is blocked?
Look for water pooling around a gully, a smell of sewage near the house, or waste visible when you lift the inspection chamber cover. Inside, several fittings draining slowly at once, or a toilet that gurgles when the bath empties, usually means a blockage further down the drain rather than in a single waste pipe.
Are flushable wipes safe to put down the toilet?
No. Wipes labelled flushable do not break down the way toilet paper does. They catch on pipe joints and roots, gather fat and other waste behind them, and are one of the most common causes of blocked drains. Put wipes, cotton buds and sanitary products in the bin instead of the toilet.
Can tree roots block a drain?
Yes. Roots grow towards water and get into drains through small gaps at the pipe joints, then form a mat that catches waste. We can cut the roots back to clear the drain, but they will regrow unless the pipe is sealed. A liner or patch repair stops roots getting back in, usually without digging.
Who pays to clear a blocked shared drain?
In England, a drain that serves more than one property is usually the responsibility of the local water company once it leaves your boundary or joins a neighbour's drain. A drain that serves only your home is yours. Our camera survey shows exactly where the blockage is, which tells you who is responsible.
