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 across Finchley

If you need a plumber in Finchley for a blocked drain, we deal with the sort of issues that turn up in Edwardian semis, interwar houses and converted flats across N3, N2 and nearby streets. Our plumbing services are set up to find the cause quickly and clear it properly, not just shift the symptom.

Blocked Toilet

A blocked toilet is often caused by too much paper, non-flushable wipes, or a partial blockage further down the soil pipe. Our engineer checks whether the problem is local to the pan or part of a wider drainage issue, then clears it using the right rods or jetting so it is less likely to come straight back.

Blocked Kitchen Sink

Kitchen sinks usually block from fat, food waste and soap residue building up in the pipework, especially where older layouts have long runs to the soil stack. We trace the restriction, clear the waste line, and check the trap and surrounding fittings so your sink drains away properly again.

Blocked Shower or Bath

Slow-draining showers and baths are often down to hair, soap scum and scale collecting in the waste, trap or branch pipe. We remove the blockage carefully, test the flow, and look for any underlying problem such as poor fall or a hidden partial blockage that could keep causing trouble.

Outside Drain Blockage

Outside drains and manholes can back up because of silt, leaves, root ingress or a collapsed section of pipe. We inspect the chamber, identify where the water is backing up, and clear the line using drainage equipment suited to the blockage, whether it is a simple clearance or a deeper fault.

High-Pressure Drain Jetting

High-pressure drain jetting is useful when a blockage is stubborn or the pipework is heavily coated with grease, sludge or debris. We use controlled water pressure to break up the build-up and flush it through the system, which is often the best option for repeat blockages in Finchley homes.

CCTV Drain Survey

If a drain keeps blocking, a CCTV drain survey lets us see exactly what is going on inside the pipe without unnecessary digging. We use the camera to spot cracks, dips, root damage or displaced joints, then explain the findings clearly so you know whether a repair or cleaning is needed.

Bad Drain Smells

Persistent drain smells can come from a partial blockage, a dry trap, a cracked pipe or waste sitting in the system for too long. We track down the source, clear any buildup, and check for ventilation or sealing issues so the smell does not keep returning through the property.

Expert Advice

“Not every blockage needs digging up. If a Finchley drain keeps blocking, I'll put a camera down to find the real cause.”
