High-Pressure Water Jetting
Water jetting is one of the most efficient ways to clear drain blockages.

It’s also effective against tougher obstructions like root systems and compacted debris, jobs that standard tools often can’t reach.

Water jetting is one of the most efficient ways to clear drain blockages. We use focused water jets to send water down the clogged area, shifting everything from common kitchen waste to soap scum and organic matter.

CCTV Drain Surveys in Herne Hill
When a blockage keeps returning or resists standard fixes, a CCTV drain survey provides a clear picture of your pipes. Rather than relying on digging or assumptions, we navigate with high-definition cameras that navigate through the pipes, delivering a continuous feed to our engineers. This process allows us to detect issues such as fractures, structural failure, tree intrusion, or excess residue. With this visual insight, we can locate the exact cause and location of the problem and plan the most effective solution.

Signs You Have a Blocked Drain
Sure, some drainage problems hit you right in the face. But most start small. Spot the early signs and you’ll save yourself a ton of bother. Check out this list of common warning signs if you think your drains might be playing up.
Water Draining Slowly
When water sits for too long 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 grease and scraps. In bathrooms, it’s often hair, soap, and mineral build-up. If water isn’t draining properly, it’s a good time to have it checked before the issue gets worse.

Unpleasant Smells
Bad smell from a drain? That’s a red flag. Grease, gunk, or worse is probably rotting. Smell it near the outdoor drain? Don’t wait. A blockage is forming.

Gurgling Sounds From Pipes
Drains gurgling? That’s a sign of trouble. Usually means water’s pushing past something. If it sounds like a kettle, get help.

Water Backing Up
Water rising instead of draining? That’s one of the clear warnings. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t clear up without help. Get on top of it early, and we’ll make sure it’s cleared quick.
Toilet Flushing Poorly
If your toilet feels off when you flush or takes ages to fill back up, there might be a clog in the drain. It’s often down to things that shouldn’t have been flushed, like wet wipes, feminine products, or just too much toilet paper.
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 backup? It can undermine your foundation. Don’t delay, call it in.
Multiple Fixtures Affected at Once
Multiple drains backing up? 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 cut it. You need a camera check and powerful flushing to clear it properly.
Damp Patches or Mould
Drain problem? It’s not always obvious. Wet marks? Dark patches? Smells near the skirting? That could be a pipe issue. Don’t leave it long.
