Our West Harrow Drainage Services

We take a firm stance against uncertainty and short-term fixes. Our experienced engineers use modern diagnostic tools and reliable practices to get to the bottom of the issue and fix it long-term. Below is an overview of the core services we deliver throughout West Harrow.

High-Pressure Water Jetting

Water jetting is our preferred technique for clearing most drain blockages due to its effectiveness, reliability, and broad application. Using powerful water streams, 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 breaking through more stubborn obstructions such as tree roots and hardened waste, making it highly suitable for situations where manual tools are less reliable.

Drain Jetting London

When it comes to unblocking pipes, we nearly always go for water jetting, it just works. It’s fast, powerful, and sorts out most of the regular issues. With high-pressure hoses, we push water through the pipe and break up grease, old food, hair, and whatever else has built up. It’s even strong enough to take on bigger clogs, far more effective than using rods for the tough stuff.

CCTV Drain Surveys in West Harrow

When a blockage proves persistent or hard to pinpoint, a CCTV drain survey provides a clear picture of your underground infrastructure. Rather than relying on digging or assumptions, we deploy high-definition cameras that travel the drain network, delivering a continuous feed to our engineers. This process allows us to identify issues such as cracks, collapsed pipework, tree intrusion, or severe waste build-up. With this visual insight, we can locate 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 stay ahead of the problem. Check out this quick checklist if you think your drains might be playing up.

Water Draining Slowly

When water is slow to leave in your sink, bath, or shower, it’s often one of the initial clues of a blockage developing. In kitchens, the most common culprits are grease and scraps. In bathrooms, it’s often hair, soap, and mineral build-up. If water isn’t flowing out smoothly, it’s a good time to get help before the issue grows bigger.

Unblocked Sink

Unpleasant Smells

Persistent foul odours coming from your drains are a reliable sign that waste material, such as kitchen waste, cooking oils, or wastewater, is building up where it shouldn’t. These materials can become lodged in your drains and begin to break down, releasing unpleasant smells. If you get a whiff of these odours near your kitchen or bathroom fixtures, it’s likely that a blockage is developing and should be addressed promptly.

Gurgling Sounds From Pipes

Drains bubbling? That’s a sign of trouble. Usually means water’s not flowing. If it sounds like a boiler, get help.

what causes blocked drains

Water Backing Up

Water not going down? That’s a blocked drain. Don’t stall. handle it before it causes damage.

Toilet Flushing Poorly

If your toilet isn’t working right or the tank refills slowly, it could mean there’s a problem somewhere in the toilet line. These blockages are often caused by non-flushables, like wipes, hygiene items, or too much paper. It’s best to have it looked at before it gets worse.

Overflowing Outdoor Drains

If you see water spilling from external drains during or after a storm, the issue may go deeper than simple surface runoff. A partial or complete underground blockage could be preventing proper drainage, causing water to accumulate. Left unaddressed, this overflow can lead to erosion, cracking, or structural issues. Prompt professional assessment is recommended to minimise damage.

Multiple Fixtures Affected at Once

If more than one fixture is sluggish, like your toilet, sink, and bath all backing up together, it’s probably not just a minor blockage. 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 likely need someone to have a check with a camera and blast it with water to sort it properly.

Damp Patches or Mould

A drainage issue isn’t always clear, but some signs can help you catch it early. If you’ve noticed moist areas on the floor or wall, mould in places you wouldn’t expect, or a mouldy odour near kitchen units or along the baseboard, it could suggest a problem behind the scenes.

    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.
