High-Pressure Water Jetting

Water jetting is our preferred technique for resolving most drain blockages due to its effectiveness, reliability, and wide use. Using high-pressure hoses, we direct a focused blast of water through the blocked area, removing common materials like oils, kitchen waste, and organic buildup.

This method is also capable of removing more difficult clogs such as tree roots and solidified material, making it highly suitable for situations where traditional drain rods are unsuccessful.

Drain Jetting London

When it comes to unblocking pipes, we nearly always go for water jetting, it just works. It’s quick, strong, and sorts out most of the usual problems. With high-pressure hoses, we push water through the pipe and blast away grease, scraps, hair, and any gunk that’s sitting there. It’s even strong enough to take on tougher blockages, much stronger than using rods for the tough stuff.

CCTV Drain Surveys in Harefield

If a blockage is recurring or persists, a CCTV survey is the best way to find out what’s happening 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 spot damage, tree growth, clogs, or pipe collapse, so we can target the cause and fix it right the first time.

Signs You Have a Blocked Drain

While some drainage issues show clear symptoms, being able to recognise 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 potential blockage in your home or commercial property.

Water Draining Slowly

Delayed water flow in sinks, bathtubs, or showers is often the first sign of a problem starting within your plumbing system. In kitchens, the cause is frequently buildup from grease and scraps, while in bathrooms, it’s typically mineral and organic deposits. If water is taking longer than normal, it’s a strong hint the system should be assessed.

Unblocked Sink

Unpleasant Smells

That foul smell near the drain? That’s not just something in the air, it’s gunk building up, starting to turn. Food, grease, even sewage can get nasty. If you’re getting whiffs like that, don’t ignore it. It means a blockage is on the move, and it’s better to get ahead of it.

Gurgling Sounds From Pipes

Odd gurgling coming from your drains, particularly gurgling or bubbling, are often a sign that there’s air in the line. This typically occurs when water is unable to flow smoothly, causing vacuum pressure. 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 flooding back 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 clear up without help. Call us in, and we’ll make sure it’s cleared quick.

Toilet Flushing Poorly

A toilet that doesn’t flush properly or takes longer than normal to refill may suggest a restriction within the connected drainage system. These blockages are often the result of inappropriate materials being flushed, common culprits include wet wipes, sanitary products, or large amounts of paper.

Overflowing Outdoor Drains

Noticed water pouring out of your outdoor drains when it rains? That might be a sign of something worse, it could mean there’s a drainage problem below that’s stopping things from draining properly. If left too long, all that overflow can even reach your house’s foundation. It’s smart to get help before it starts costing more.

Multiple Fixtures Affected at Once

Multiple drains acting up? That’s not a small issue. If toilets, sinks, and your washer are all blocked, the blockage is probably deep in the main line. Plunging won’t solve it. You need a CCTV inspection and powerful flushing to sort it for good.

Damp Patches or Mould

Sometimes it starts with a smell. A musty hint near the cupboard. A dark patch curling across the base of a wall. Maybe even a fuzzy patch by the skirting. These quiet warnings often mean something deeper, a slow buildup, out of sight, slowly doing damage.

    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.

    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.
