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 fix across Chelsea

If you need a plumber in Chelsea for a blocked drain, we deal with everything from slow-running sinks to serious outside drain backups. Our engineers work across Chelsea SW3, South Kensington, Fulham and nearby postcodes, with fast, tidy repairs suited to period homes and mansion blocks.

Blocked Toilet Repair

A blocked toilet is often caused by too much paper, sanitary products, wipes or a fault in the pipework further along the line. We trace the blockage, clear it safely without damaging the pan or soil pipe, and check the flush is carrying waste away properly.

Blocked Kitchen Sink

Kitchen sinks usually back up because grease, food waste and soap residue build up in the waste trap and pipework. We clear the blockage, inspect the trap and pipe run, and make sure water is draining freely before leaving the area clean and usable.

Blocked Shower Drain

Shower and bath blockages are commonly caused by hair, soap scum and limescale narrowing the waste pipe. We remove the blockage, test the drain flow and look for any hidden issue such as poor pipe fall or a partial obstruction deeper in the system.

Outside Drain Blockage

Outside drains and manholes can block with wet wipes, silt, fat and leaves, which often leads to slow drainage or overflow near the property. We locate the problem, clear the run and check the chambers, which is especially useful in older Chelsea terraces and basement flats.

High Pressure Jetting

High-pressure drain jetting uses a focused water jet to break up grease, scale and stubborn debris inside the pipework. It is a reliable way to clear recurring blockages in shared drains, long runs and older properties where standard rodding is not enough.

CCTV Drain Survey

A CCTV drain survey lets us see inside the pipework and identify cracks, displaced joints, root ingress or repeated blockages without guesswork. We use it when the same drain keeps backing up, or when you need clear evidence before repair work is agreed.

Bad Drain Smells

Persistent drain smells often point to a partial blockage, dry trap, damaged seal or a venting issue in the drainage system. We find the source of the odour, clear any obstruction and check the fittings so the smell does not keep returning.

Expert Advice

““Blocked drains in Chelsea can be caused by shared stacks, older pipework and everyday build-up from busy kitchens and bathrooms. I use the right kit for the property, whether it is a basement flat near Fulham Road or a townhouse off Chelsea Embankment.””
