High-Pressure Water Jetting
When it comes to getting drains moving, we nearly always go for water jetting, it just works. It’s quick, powerful, and sorts out most of the regular issues. With jetting gear, we send pressure down the pipe and break up grease, old food, hair, and whatever else has built up. It’s even strong enough to take on tree roots, far more effective than using rods for the hard jobs.

Water jetting is one of the most efficient ways to clear drain blockages. We use high-pressure hoses 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 tougher obstructions like root systems and hardened waste: jobs that traditional rods often can’t reach.

CCTV Drain Surveys in Clerkenwell
If a blockage is recurring or persists, a CCTV survey is the best way to understand the problem inside your drains. We send in a small, high-definition camera into the system, which lets us check the full layout without disruption. This footage helps us highlight damage, root intrusion, clogs, or sections that have failed, so we can locate the problem precisely and determine the best course of action.

Signs You Have a Blocked Drain
While some drainage issues are immediately obvious, identifying early warning signs can help you avoid unnecessary disruption and expense. Below is a guide of common indicators to keep an eye on if you suspect a developing issue in your home or commercial property.
Water Draining Slowly
When water takes longer to drain in your sink, bath, or shower, it’s often one of the initial clues of a blockage starting to build. In kitchens, the most common culprits are fat and leftover food. In bathrooms, it’s often scum and scale. If water isn’t flowing out smoothly, it’s a good time to get help before the issue gets worse.

Unpleasant Smells
That rotten whiff near the drain? That’s not just something in the air, it’s waste stuck in your pipes, starting to rot. Food, grease, even sewage can sit and fester. If you’re picking up a stink, don’t ignore it. It means a problem is getting worse, and it’s better to get ahead of it.

Gurgling Sounds From Pipes
If your drains start making weird noises, it usually means air’s getting trapped because water’s not flowing properly. That often points to a clog down the line. If your pipes are making odd bubbling noises, it’s probably time to call someone in.

Water Backing Up
One of the most apparent indicators of a blocked drain is water rising back up. If you notice any sign of water backing up, it’s important to address the issue promptly to prevent it from developing further.
Toilet Flushing Poorly
Toilet not emptying or filling slow? Might be a blockage in the drain. Wipes, tampons, or too much paper usually to blame. Call it in.
Overflowing Outdoor Drains
Water pouring out of outside drains after rain? That’s a red flag. Might be a serious backup. If water can’t get through, it overflows. That overflow? It can crack driveways. Don’t wait, call it in.
Multiple Fixtures Affected at Once
Multiple drains slowing down? That’s not a minor fault. If toilets, sinks, and your washer are all backing up, the blockage is probably deep in the main line. Plunging won’t solve it. You need a CCTV inspection and high-pressure water jetting to clear it properly.
Damp Patches or Mould
Sometimes it starts with a scent. A faint odour near the cupboard. A dark patch spreading in a corner. Maybe even a fuzzy patch by the skirting. These subtle signs often mean something lurking, a leak or blockage, hiding underfoot, slowly making its presence known.
