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 in Sunbury

If you need a plumber in Sunbury for a blocked drain, we deal with the slow, messy problems that build up in homes across TW16 and nearby areas. From riverside properties to newer estates, our engineers find the cause quickly and clear it with the right approach.

Blocked Toilet

A blocked toilet is often caused by too much paper, wipes, sanitary products, or a partial blockage further down the soil pipe. We assess whether it is a local toilet issue or a larger drain problem, then clear it safely without damaging the pipework.

Blocked Kitchen Sink

Kitchen sinks usually block because of cooking fat, food debris, and soap residue hardening in the waste pipe. We clear the blockage, check the trap and pipe run, and make sure water is draining properly so the problem does not come straight back.

Blocked Shower or Bath

Hair, soap scum, and limescale can slow shower and bath drains until water starts pooling around your feet. We remove the blockage, inspect the waste pipe for hidden build-up, and restore normal flow without leaving the bathroom in a worse state.

Outside Drain Blockage

Outside drains and manholes often block because of silt, leaves, wipes, or tree roots getting into the system. We lift the cover, identify where the backup is happening, and clear the line properly, which is especially useful on older runs serving homes in Sunbury-on-Thames and nearby streets.

High Pressure Jetting

High-pressure drain jetting is used when ordinary rodding is not enough, or when grease, sludge, and debris are sticking to the inside of the pipe. Our engineer uses controlled jetting equipment to break the blockage down and flush the drain through thoroughly.

CCTV Drain Survey

If a drain keeps blocking, a CCTV drain survey helps us see exactly what is going on inside the pipe. We use a camera to find cracks, collapses, root ingress, or displaced joints, then explain the issue clearly so you know the best next step.

Bad Drain Smells

Bad drain smells can come from a partial blockage, dry traps, trapped waste, or a faulty vent in the drainage system. We trace the source, clear any build-up, and check the pipework so the smell is dealt with at the cause, not just masked.

Expert Advice

“Blocked drains in Sunbury-on-Thames often show up after wet weather, especially where gullies, shared runs, or older pipework are involved. I use the right equipment to clear the blockage, then check why it formed so the problem is less likely to return.”
