What causes blocked drains in homes?

The most common causes are a build-up of grease, fat and food debris in kitchen drains, hair and soap scum in bathroom drains, and root ingress or collapsed pipework in outdoor drains. Baby wipes, cotton pads and sanitary products flushed down toilets are also a very frequent cause of blockages. Regular maintenance can help prevent most blockages from developing.

Can you unblock a drain on the same day?

In most cases, yes. We carry drain rods, high-pressure water jetting equipment and CCTV drain cameras in our vans, so we can tackle most blockages the same day you call. Severe root ingress or collapsed pipes may require additional investigation, but we'll advise you fully before any extra work is carried out.

How do I know if I have a blocked drain?

Common signs include slow-draining sinks or baths, gurgling noises from pipes or toilets, unpleasant odours from drains, and in more serious cases, water backing up out of the drain. If you notice any of these, it's worth calling us before the blockage becomes a complete stoppage.

Do you use water jetting or drain rods?

We use the most appropriate method for each situation. Drain rods work well for straightforward blockages, while high-pressure water jetting is more effective for stubborn grease build-up and longer runs of pipework. For suspected root ingress or structural issues we use CCTV cameras to inspect the drain before recommending a solution.

Is drain clearance covered by home insurance?

Some home insurance policies include drainage cover — it's worth checking your policy documents or calling your insurer. We can provide a detailed report of the blockage and the work carried out, which most insurers will accept as supporting documentation for a claim.

Blocked drain problems we sort for Chiswick homes

If you need a plumber in Chiswick for a blocked drain, we deal with everything from slow running sinks to more serious outside drain issues. We work across W4 and nearby areas like Acton and Hammersmith, from Edwardian terraces in Bedford Park to riverside homes and period conversions.

Blocked Toilet

A blocked toilet is often caused by too much paper, wipes, or a partial blockage further down the waste pipe. Our engineer checks whether the problem is local to the pan or deeper in the drainage line, then clears it without causing damage to the soil stack or pan connector.

Blocked Kitchen Sink

Kitchen sinks usually block because of grease, food waste, soap residue, and narrow pipe runs that build up over time. We trace the blockage, clear the pipework, and check for poor fall or recurring fat deposits so the sink drains properly again.

Blocked Shower or Bath

Hair, soap scum, and limescale are the usual causes of a slow or blocked shower or bath. We remove the obstruction from the trap or waste line, then test the flow to make sure water is draining away cleanly without leaving standing water behind.

Outside Drain Blockage

Outside drains and manholes can back up because of leaves, silt, wipes, or a cracked section where debris catches. We inspect the chamber, locate the blockage, and clear it safely, which is especially useful for older properties in W4 where drains may have several bends or junctions.

High Pressure Jetting

High-pressure drain jetting is used when a blockage is too stubborn for rods alone, or when pipe walls are coated with grease and sludge. We use the right jetting nozzle and pressure for the drain size, which clears the pipe thoroughly without unnecessary digging.

CCTV Drain Survey

A CCTV drain survey helps when a drain keeps blocking or you want to know why waste is not flowing away properly. We use a camera to inspect the pipework, then identify cracks, roots, offsets, or collapsed sections so you have a clear picture of what needs fixing.

Bad Drain Smells

Bad drain smells often point to a partial blockage, trapped waste, a dry trap, or a venting issue in the drainage system. We check the likely source, clear any build-up, and make sure the trap seals and pipework are working as they should so the smell does not return.
