High-Pressure Water Jetting

Water jetting is one of the most reliable ways to clear drain blockages. We use high-pressure hoses to push fluid past the clogged area, breaking up everything from common kitchen waste to hair and built-up grime. It’s also effective against hard-to-remove blockages like root systems and compacted debris, jobs that standard tools often can’t reach.

CCTV Drain Surveys in Merton

If a blockage is recurring or persists, a CCTV survey is the best way to understand the problem inside your drains. We send in a small, high-definition camera into the system, which lets us check the full layout without removing anything. This footage helps us identify breaks, tree growth, clogs, or pipe collapse, so we can locate the problem precisely and determine the best course of action.

Signs You Have a Blocked Drain

While some drainage issues are immediately obvious, spotting early warning signs can help you prevent costly problems. Below is a guide of common indicators to keep an eye on if you suspect a drainage problem in your residence or business.

Water Draining Slowly

When water is slow to leave in your sink, bath, or shower, it’s often one of the early symptoms of a blockage developing. In kitchens, the most common culprits are oil and cooking waste. In bathrooms, it’s often scum and scale. If water isn’t flowing out smoothly, it’s a good time to get help before the issue grows bigger.

Unblocked Sink

Unpleasant Smells

If you’re noticing a pong coming from your sink, it usually means a bit of a problem’s brewing where it shouldn’t be. Old food, fat, or something grim can get caught and start to rot. It’s best not to hope it goes away, a bad smell is often a sign that a blockage is already in the works.

Gurgling Sounds From Pipes

Unusual sounds coming from your drains, particularly air-like noises, are often a sign that air pockets are forming. This typically occurs when water is disrupted by an obstruction, causing air to be drawn in behind it. If your pipes begin making noises reminiscent of a kettle, it’s recommended to have them checked by a specialist.

what causes blocked drains

Water Backing Up

Water rising instead of draining? That’s one of the clear warnings. A blocked drain is likely the cause. And trust me, if you’ve seen it once, it won’t fix itself. Call us in, and we’ll make sure it’s sorted in no time.

Toilet Flushing Poorly

If your toilet isn’t working right or struggles to reset, it could mean there’s a problem somewhere in the toilet line. These blockages are often caused by items not meant for drains, like personal cloths, sanitary products, or too much paper. It’s best to call in help before it gets worse.

Overflowing Outdoor Drains

Water pouring out of outside drains after rain? That’s a warning sign. Might be a clog in the line. If water can’t get through, it backs up. That mess? It can crack driveways. Don’t wait, call it in.

Multiple Fixtures Affected at Once

If more than one thing’s draining slowly, like your toilet, sink, and bath all being weird at the same time, it’s probably not just a small clog. When it’s in the main drain, everything gets affected. A quick go with a plunger won’t do the trick here. You’ll want to get someone in to inspect things with a camera and clear it with pressure to get things moving again.

Damp Patches or Mould

Hidden blockages can creep in. One day everything’s fine, then suddenly, damp patches on the floor, stuff growing where it shouldn’t, or a musty odour near the skirting board. If it feels off, it probably is. And we are ready to fix it.

    Garden sorted, no more flooding.

    Cheers to Clark Drainage for getting our garden sorted after that downpour. Great job. We’d tried a few things ourselves with no luck, but they came in, identified the issue quickly, and had the drainage working perfectly again.

    Proper pride in their work.

    It’s not glamorous work but they do it with a smile and real pride. Can’t say I’ve ever seen someone so happy clearing a drain, but they made the whole thing stress-free and even a bit fun.
