High-Pressure Water Jetting

Water jetting is our go-to method for resolving most drain blockages due to its efficiency, reliability, and versatility. Using specialised jetting equipment, we direct a powerful stream of water through the obstructed section of pipe, removing common materials like oils, food particles, and organic buildup.

This method is also capable of breaking through more stubborn obstructions such as tree roots and solidified material, making it highly suitable for situations where manual tools are less reliable.

Drain Jetting London

Water jetting not only addresses the issue but also washes out the full width of the pipe, significantly lowering the risk of recurring problems. It’s a gentle yet effective solution for most drainage systems, and far less disruptive than manual clearing or groundwork. Every one of our field units is equipped with high-powered jetting units, and our engineers are certified for safe use. In most cases, we can resolve the problem in a single visit without the need for additional intervention.

CCTV Drain Surveys in Isleworth

If a blockage won’t stay gone, a CCTV drain survey helps us get to the bottom of it inside the pipes. Instead of pulling things apart or guessing, we thread a lens through the drain and take a proper look. It shows us if there are breaks, damage, tree roots, or a big old clog of waste. That way, we know where the problem sits and how to sort it.

Signs You Have a Blocked Drain

Sure, some drainage problems are impossible to miss. But most begin quietly. Spot the early signs and you’ll stop it before it spreads. Check out this quick checklist if you think your drains might be acting strange.

Water Draining Slowly

Delayed water flow in sinks, bathtubs, or showers is often the first sign of a forming blockage within your plumbing system. In kitchens, the cause is frequently fat and food waste, while in bathrooms, it’s typically a build-up of hair, soap residue, and mineral scale. If water is lingering, it’s a clear sign the system should be assessed.

Unblocked Sink

Unpleasant Smells

Unpleasant drain scents emanating from your drains are a clear indicator that waste material, such as kitchen waste, grease, or wastewater, is accumulating where it shouldn’t. These materials can become lodged in your drains and begin to rot, releasing unpleasant smells. If you notice these odours near your indoor or outdoor drains, it’s likely that a blockage is developing and should be sorted quickly.

Gurgling Sounds From Pipes

Strange noises in your plumbing, especially gurgling or bubbling, are often caused by air pockets, which appears when water can’t pass by a blockage. If your pipes are gurgling oddly, it’s a good idea to get it checked early.

what causes blocked drains

Water Backing Up

Water backing up instead of draining? That’s one of the obvious signs. A blocked drain is likely the cause. And trust me, if you’ve seen it once, it won’t fix itself. Act fast, and we’ll make sure it’s gone fast.

Toilet Flushing Poorly

A toilet that struggles to clear waste 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, feminine hygiene items, or too much tissue.

Overflowing Outdoor Drains

Water rising up in outside drains after rain? That’s a red flag. Might be a clog in the line. If water can’t get through, it comes out. That mess? It can wreck gardens. Don’t delay, get it sorted.

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, the whole system gets hit. A quick go with a plunger won’t do the trick here. You’ll want to get someone in to take a proper look with a camera and use jetting gear to sort it properly.

Damp Patches or Mould

Drain problem? It’s not always obvious. Wet marks? Fungal growth? Stale odour under the sink? That could be a hidden leak. Don’t leave it long.

    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.

    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.

    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.

    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.
