We don’t go for guesswork or do temporary solutions. With a team of trained specialists, modern tools, and a straightforward method, we zero in on the source and fixing it properly. Here’s a quick overview at the main things we offer across Welsh Harp.

High-Pressure Water Jetting

Water jetting is our go-to method for resolving most drain blockages due to its speed, thoroughness, and versatility. Using high-pressure hoses, we direct a concentrated jet of water through the blocked area, breaking up common materials like grease, food particles, and organic buildup.

This method is also capable of removing more resilient blockages such as root intrusions and hardened waste, making it highly suitable for situations where older methods are ineffective.

Drain Jetting London

Water jetting is one of the most reliable ways to clear drain blockages. We use specialist tools to force water through the clogged area, dislodging everything from food waste and grease to soap scum and organic matter. It’s also effective against hard-to-remove blockages like tree roots and compacted debris: jobs that traditional rods often can’t manage.

CCTV Drain Surveys in Welsh Harp

When a blockage proves persistent or difficult to diagnose, a CCTV drain survey provides a detailed inspection of your underground infrastructure. Rather than relying on disruptive methods or guesswork, we insert high-definition cameras that move inside your system, delivering a continuous feed to our engineers. This process allows us to spot issues such as fractures, collapsed pipework, tree intrusion, or excess residue. With this footage, we can identify the true source of the problem and determine the most effective solution.

Signs You Have a Blocked Drain

While some drainage issues are immediately obvious, identifying early warning signs can help you intervene before it escalates. Below is a list of common indicators to look out for if you suspect a developing issue in your residence or business.

Water Draining Slowly

When water sits for too long in your sink, bath, or shower, it’s often one of the first signs of a blockage starting to build. In kitchens, the most common culprits are grease and scraps. In bathrooms, it’s often soap residue and strands. If water isn’t flowing out smoothly, it’s a good time to book an inspection before the issue causes problems.

Unblocked Sink

Unpleasant Smells

If you’re gettin’ a bad whiff coming from your outside drain, it usually means something’s stuck where it shouldn’t be. Old food, fat, or something grim can build up down there and go bad. It’s best not to ignore it, a bad smell is often a sign that a clog is already getting started.

Gurgling Sounds From Pipes

Unusual sounds coming from your drains, particularly gurgling or bubbling, are often a sign that air is trapped in the plumbing system. This typically occurs when water is struggling to move past a blockage, causing air to be drawn in behind it. If your pipes begin making noises reminiscent of a kettle, it’s recommended to have them professionally inspected.

what causes blocked drains

Water Backing Up

Water backing up instead of draining? That’s one of the big red flags. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t get better on its own. Get on top of it early, and we’ll make sure it’s cleared quick.

Toilet Flushing Poorly

Toilet not emptying or refilling right? Might be a plug in the line. Wet wipes, pads, or tissue usually to blame. Time to clear it out.

Overflowing Outdoor Drains

Water pouring out of outside drains after rain? That’s a problem. Might be a blockage underground. If water can’t get through, it comes out. That mess? It can crack driveways. Don’t delay, deal with it.

Multiple Fixtures Affected at Once

If more than one fixture is sluggish, like your toilet, sink, and bath all playing up together, it’s probably not just a simple fix. When it’s in the main drain, even your washing machine can feel it. A quick go with a plunger won’t help much here. You’ll want to get someone in to take a proper look with a camera and blast it with water to sort it properly.

Damp Patches or Mould

Drain problem? It’s not always obvious. Wet marks? Mould in odd spots? Smells near the skirting? That could be a hidden leak. Get it looked at.

    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.
