Our Willesden Drainage Services
Clark Drainage offers a complete suite of professional drainage services for homes and businesses throughout Willesden. From urgent issues such as blocked toilets at night to more involved tasks like complete system digs, our team is set up and trained to respond at all times.
We take a strong view against guesswork and quick patches. Our qualified professionals use modern diagnostic tools and proven methods to identify the root cause and resolve it thoroughly. Below is an introduction of the key services we deliver throughout Willesden.
High-Pressure Water Jetting
Water jetting’s the answer. Fast, tough, and gets through it all. We use high-pressure hoses to blast apart grease, hair, food, and solid stuff. Nothing else cuts through it like this. Rods? Fine for minor blocks. Jetting? Built for the serious clogs.

Water jetting not only resolves the current blockage 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 manual clearing or groundwork. Every one of our vans is equipped with advanced jetting systems, and our engineers are trained to operate them with precision and safety. In most cases, we can clear the blockage in a single visit without the need for additional intervention.

CCTV Drain Surveys in Willesden
If a blockage keeps coming back, a CCTV drain survey helps us get to the bottom of it inside the pipes. Instead of tearing things up or making assumptions, we send in a camera the drain and take a proper look. It shows us if there are breaks, damage, roots growing in, or a big old build-up of mess. That way, we know exactly what the issue is and how to sort it.

Signs You Have a Blocked Drain
While some drainage issues are immediately obvious, being able to recognise early warning signs can help you avoid unnecessary disruption and expense. Below is a guide of common indicators to watch for if you suspect a drainage problem in your house or workplace.
Water Draining Slowly
When water takes longer to drain 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 oil and cooking waste. In bathrooms, it’s often soap residue and strands. If water isn’t moving like normal, it’s a good time to get help before the issue causes problems.

Unpleasant Smells
That rotten whiff near the sink? That’s not just something in the air, it’s stuff left behind, starting to turn. Food, grease, even sewage can get caught up. If you’re smelling something off, don’t ignore it. It means a blockage is on the move, and it’s better to sort it quickly.

Gurgling Sounds From Pipes
Drains bubbling? That’s a sign of trouble. Usually means water’s fighting a blockage. If it sounds like a kettle, sort it.

Water Backing Up
A pretty obvious clue your drain’s blocked is when water starts coming back up. If you notice it, it’s a good idea to get it looked at before long before it causes trouble.
Toilet Flushing Poorly
If your toilet isn’t working right or the tank refills slowly, it could mean there’s a clog somewhere in the drainage system. These blockages are often caused by items not meant for drains, like personal cloths, hygiene items, or a build-up of tissue. It’s best to call in help before it gets worse.
Overflowing Outdoor Drains
If you see water emerging from external drains during or after a storm, the issue may extend beyond simple surface runoff. A minor or full underground blockage could be preventing proper drainage, causing water to accumulate. Left ignored, this overflow can damage gardens, driveways, and even the structural foundations of your property. Prompt intervention is advised to minimise damage.
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 simple fix. 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 inspect things with a camera and use jetting gear to sort it properly.
Damp Patches or Mould
Buried drain issues can show up when you least expect. One day everything’s fine, then before you know it, soggy skirting, stuff growing where it shouldn’t, or a nasty whiff near the skirting board. If it doesn’t seem right, it probably is. And we know exactly how to find it.
