Our Hornsey Drainage Services
Clark Drainage sorts it out. Homes, businesses, across Hornsey. Blocked toilet at some ungodly hour? We’re on it. Full drain excavation? No problem. We’re good to go, day or night.
We take a strong view against trial-and-error and quick patches. Our qualified professionals use modern diagnostic tools and reliable practices to understand the core problem and correct it properly. Below is an introduction of the core services we provide throughout Hornsey.
High-Pressure Water Jetting
Water jetting’s the answer. Quick, tough, and gets through it all. We use water force to smash through grease, hair, food, and roots. Nothing else cuts through it like this. Rods? Fine for easy stuff. Jetting? Built for the heavy stuff.

Water jetting not only addresses the issue but also thoroughly cleans the full interior of the pipe, significantly lowering the risk of future issues. It’s a gentle yet effective solution for most drainage systems, and far less disruptive than mechanical rodding or digging. 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 clear the blockage in a single visit without the need for further service.

CCTV Drain Surveys in Hornsey
If a blockage is stubborn or persists, a CCTV survey is the best way to find out what’s happening inside your drains. We insert a small, high-definition camera into the system, giving us a full view without removing anything. This footage helps us highlight breaks, tree growth, blockages, or sections that have failed, so we can pinpoint the issue and fix it right the first time.

Signs You Have a Blocked Drain
Not all drainage issues are obvious from the start. Many start with small, easy-to-miss signs that can lead to bigger problems if ignored. Here are some of the most common things to look for to keep an eye on, whether you’re at the house or managing a site.
Water Draining Slowly
Delayed water flow in common household drains is often the first sign of a forming blockage within your plumbing system. In kitchens, the culprit is frequently fat and food waste, while in bathrooms, it’s typically mineral and organic deposits. If water is sitting, it’s a clear sign the system should be checked.

Unpleasant Smells
Nasty whiff from a drain? That’s a warning sign. Grease, fat, or worse is probably rotting. Smell it near the sink? Don’t wait. A clog is forming.

Gurgling Sounds From Pipes
If your drains start acting up with gurgles, it usually means air’s getting trapped because water’s hitting a blockage. That often means a clog down the line. If your pipes are making odd bubbling noises, it’s probably time to call someone in.

Water Backing Up
Water backing up instead of draining? That’s one of the big red flags. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t clear up without help. Act fast, and we’ll make sure it’s sorted in no time.
Toilet Flushing Poorly
If your toilet isn’t running smoothly or takes a long time to refill, it could mean there’s a clog somewhere in the drainage system. These blockages are often caused by non-flushables, like personal cloths, sanitary products, or large amounts of toilet roll. It’s best to have it looked at before it gets worse.
Overflowing Outdoor Drains
If you see water overflowing out of external drains during or after a storm, the issue may extend beyond simple surface runoff. A partial or complete underground blockage could be stopping water from flowing, causing water to back up. Left untreated, this overflow can damage gardens, driveways, and even the structural foundations of your property. Prompt professional assessment is recommended to prevent further complications.
Multiple Fixtures Affected at Once
When different parts of your plumbing in your property are backing up simultaneously, it’s often linked to a deeper issue within the central pipework. Such obstructions can affect the function of everything from the toilet to the washing machine. In these scenarios, simple methods like plunging are unlikely to be sufficient. A proper assessment using CCTV technology, followed by power flushing, is typically recommended to get rid of the obstruction.
Damp Patches or Mould
Drain problem? It’s not always obvious. Wet marks? Dark patches? Stale odour under the sink? That could be a pipe issue. Get it looked at.
