Our Harlesden Drainage Services

We provide complete drainage support for both homes and businesses throughout Harlesden. Whether you’re facing an urgent issue like a blocked toilet at night or require a full-system fix, our team is ready to respond around the clock.

No guessing. No patch jobs. Our engineers are trained. The gear is top-grade. We find the problem. We fix it right. Here’s what we do in Harlesden.

High-Pressure Water Jetting

Water jetting is one of the most efficient ways to clear drain blockages. We use focused water jets to force water through the clogged area, dislodging everything from food waste and grease to hair and built-up grime. It’s also effective against deeper clogs like root systems and hardened waste, jobs that standard tools often can’t clear.

Drain Jetting London

Water jetting not only addresses the issue but also thoroughly cleans the full width of the pipe, reducing the risk of future issues. It’s a safe and non-invasive method for most drainage systems, and far less disruptive than mechanical rodding or excavation. Every one of our vans is equipped with high-powered jetting units, and our engineers are certified for safe use. In most cases, we can clear the blockage in a single visit without the need for further service.

CCTV Drain Surveys in Harlesden

If a blockage is uncooperative or persists, a CCTV survey is the best way to understand the problem inside your drains. We thread 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 choose the most efficient fix.

Signs You Have a Blocked Drain

While some drainage issues show clear symptoms, spotting 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

Water backing up? Sink, bath, or shower, it’s the first sign of a blockage. In the kitchen, it’s fat and food. In the bathroom, hair and soap. Don’t wait. Fix it now.

Unblocked Sink

Unpleasant Smells

Nasty whiff from a drain? That’s a trouble alert. Waste, sewage, or worse is probably rotting. Smell it near the outdoor drain? Don’t wait. A clog is forming.

Gurgling Sounds From Pipes

Drains bubbling? That’s trapped air. Usually means water’s pushing past something. If it sounds like a blocked sink, get it checked.

what causes blocked drains

Water Backing Up

Water coming back up? That’s a blocked drain. Don’t stall. Sort it before it gets worse.

Toilet Flushing Poorly

Toilet not clearing or filling slow? Might be a clog in the soil pipe. Wipes, sanitary stuff, or too much paper usually to blame. Call it in.

Overflowing Outdoor Drains

Water spilling from outside drains after rain? That’s a red flag. Might be a blockage underground. If water can’t get through, it comes out. That mess? It can crack driveways. Don’t wait, get it sorted.

Multiple Fixtures Affected at Once

If more than one thing’s draining slowly, like your toilet, sink, and bath all being weird at the same time, it’s probably not just a minor blockage. When it’s in the main drain, even your washing machine can feel it. A quick go with a plunger won’t do the trick here. You’ll probably need a pro to take a proper look with a camera and blast it with water to shift the blockage.

Damp Patches or Mould

A drainage issue isn’t always easy to spot, but some signs can help you know what to look for. If you’ve noticed wet spots on the floor or wall, mildew in odd corners, or a musty smell near kitchen units or skirting boards, it could suggest a drainage issue.

    Bang on time, job done fast.

    Turned up bang on time and were done quicker than expected. Cheers lads! Was expecting a drawn-out job, but they clearly knew what they were doing and just cracked on.

    Explained everything so simply.

    I had no clue what was going on with our pipes but they explained it all so clearly. Felt completely reassured the whole time and appreciated how patient they were with my questions.

    Down to earth and skilled.

    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.

    Didn’t let us down.

    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.

  • 17/08/2025

    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.
