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 in Kingston

If you need a plumber in Kingston for a blocked drain, we can help quickly and without fuss. From KT1 terraces to riverside flats in Kingston upon Thames, we deal with the messy stuff properly and get drains flowing again.

Blocked Toilet

A blocked toilet is often caused by too much paper, wipes, sanitary products, or a partial blockage further down the branch pipe. Our engineer clears the blockage, checks the flow, and makes sure the toilet is flushing away properly before leaving.

Blocked Kitchen Sink

Kitchen sinks usually block because grease, food waste, and soap build up in the waste pipe, especially in busy homes and flats. We trace the restriction, clear the pipework, and check the trap and waste run so the sink drains freely again.

Blocked Shower or Bath

Hair, soap scum, and limescale are the usual reasons a shower or bath starts draining slowly or backing up. We remove the blockage, inspect the plughole and waste connection, and test the drain so you are not left standing in water.

Outside Drain or Manhole Blockage

If an outside drain or manhole is overflowing, the problem is often tree roots, silt, collapsed pipework, or a solid build-up in the drain line. We clear the blockage safely, identify where it is coming from, and check the system for signs of damage.

High Pressure Jetting

High-pressure drain jetting is used when a blockage needs a stronger clean than rods alone can provide. We use controlled water pressure to break up grease, sludge, and debris, which is especially useful on shared lines and older drainage runs in places like Surbiton and New Malden.

CCTV Drain Survey

A CCTV drain survey lets us see inside the pipework, so we can find recurring blockages, cracks, root ingress, or displaced joints without guesswork. It is a practical option when the drain keeps backing up or when you want clear evidence before repair work starts.

Bad Drain Smells

Bad smells from drains can come from a partial blockage, a dry trap, poor ventilation, or waste sitting in the pipework. We find the source of the smell, clear any hidden buildup, and check the system so your kitchen, bathroom, or hallway does not keep smelling damp and foul.

Expert Advice

“Blocked drains in Kingston upon Thames often come down to a mix of older pipework, tree roots, and heavy use in busy households. I check the system properly, from the internal waste to the outside run, so we clear the blockage and understand why it happened.”
