High-Pressure Water Jetting

Water jetting’s the way. Fast, tough, and doesn’t miss. We use high-pressure hoses to cut into grease, hair, food, and roots. Nothing else cuts through it like this. Rods? Fine for light jobs. Jetting? Built for the heavy stuff.

Drain Jetting London

Water jetting is one of the most effective ways to clear drain blockages. We use specialist tools to force water through the clogged area, shifting everything from common kitchen waste to hair and built-up grime. It’s also effective against deeper clogs like tree roots and hardened waste: jobs that traditional rods often can’t clear.

CCTV Drain Surveys in Sydenham

When a blockage keeps returning or difficult to diagnose, a CCTV drain survey provides a clear picture of your pipes. Rather than relying on disruptive methods or guesswork, we insert high-definition cameras that move inside your system, delivering real-time video to our engineers. This process allows us to spot issues such as fractures, structural failure, tree intrusion, or excess residue. With this footage, we can pinpoint the exact cause and location of the problem and determine the most effective solution.

Signs You Have a Blocked Drain

Sure, some drainage problems make themselves known fast. But most start small. Spot the early signs and you’ll stop it before it spreads. Check out this list of common warning signs if you think your drains might be getting blocked.

Water Draining Slowly

Water not moving like before? If your sink, bath, or shower’s lagging, that’s usually the big hint. In the kitchen, it’s food and fat. In the bathroom? Hair, soap, and scale are the biggest offenders. If water’s sitting still, it’s time to act.

Unblocked Sink

Unpleasant Smells

That rotten whiff near the sink? That’s not just something in the air, it’s waste stuck in your pipes, starting to rot. Food, grease, even sewage can sit and fester. If you’re picking up a stink, don’t ignore it. It means a problem is on the move, and it’s better to sort it quickly.

Gurgling Sounds From Pipes

Unfamiliar bubbling in your plumbing, especially fluid-like sounds, are often caused by air stuck in the system, which appears when water is slowed down by a blockage. If your pipes are bubbling like a blocked sink, it’s a good idea to get it inspected.

what causes blocked drains

Water Backing Up

Water backing up instead of draining? That’s one of the clear warnings. A blocked drain is probably to blame. And trust me, if you’ve spotted it, it won’t get better on its own. Call us in, and we’ll make sure it’s cleared quick.

Toilet Flushing Poorly

If your toilet isn’t flushing right or takes ages to fill back up, there might be a clog in the drain. It’s often down to stuff that didn’t belong, like baby wipes, sanitary bits, or just too much toilet paper.

Overflowing Outdoor Drains

If you observe water spilling from external drains during or after rainfall, the issue may extend beyond simple surface runoff. A minor or full underground blockage could be preventing proper drainage, causing water to overflow. Left ignored, this overflow can lead to erosion, cracking, or structural issues. Prompt intervention is advised to minimise damage.

Multiple Fixtures Affected at Once

When several plumbing fixtures in your property are backing up simultaneously, it’s often linked to a system-level problem within the primary drainage channel. Such obstructions can impact the function of several fixtures at once. In these cases, quick fixes like manual clearing are unlikely to be sufficient. A thorough investigation using CCTV technology, followed by professional jetting, is typically recommended to locate and clear the obstruction.

Damp Patches or Mould

Drain problem? It’s not always obvious. Water stains? Fungal growth? Smells near the skirting? That could be a buried blockage. Get it looked at.

    Really down-to-earth team who know what they’re doing. Cheers for the help. From the moment they turned up, it was clear we were in good hands. They made the whole process simple and stress-free.

    They were recommended by a mate and didn’t disappoint. From the first phone call to the final clean-up, it was clear they knew their stuff. We felt confident we were in good hands the entire time.

    Surprisingly brilliant.

    Never thought I’d be raving about a drain company but here we are. They were just that good. Helpful, friendly, honest – and most importantly, they fixed the problem without any stress.

    Detailed and really useful.

    Had a CCTV survey done. Report was super detailed and made it easy for our builder.

    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.

  • 17/08/2025

    Quick turnaround and sorted fast.

    The lads came out next day and fixed the issue in half an hour. It had been bothering us for weeks, so to see it sorted that quickly was honestly a huge relief.

  • 16/08/2025

    Did it right first time.

    We’d had other companies round who couldn’t fix it. Clark Drainage had it sorted in one visit. The difference in professionalism and competence was night and day. Absolutely brilliant from start to finish.

  • 14/08/2025

    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.
