High-Pressure Water Jetting
Water jetting is one of the most reliable ways to clear drain blockages. We use specialist tools to push fluid past the clogged area, dislodging everything from common kitchen waste to hair and built-up grime. It’s also effective against hard-to-remove blockages like root systems and compacted debris, jobs that standard tools often can’t reach.

Water jetting’s the fix. Fast, solid, and gets through it all. We use high-pressure hoses to smash through grease, hair, food, and solid stuff. Nothing else does the job like this. Rods? Fine for minor blocks. Jetting? Built for the serious clogs.

CCTV Drain Surveys in Dollis Hill
When a blockage isn’t straightforward or difficult to diagnose, a CCTV drain survey provides a clear picture of your drainage system. Rather than relying on disruptive methods or guesswork, we deploy high-definition cameras that move inside your system, delivering live footage to our engineers. This process allows us to identify issues such as fractures, collapsed pipework, root ingress, or excess residue. With this information, we can pinpoint the true source of the problem and determine the right course of action.

Signs You Have a Blocked Drain
Not all drainage issues shout for attention. Many start with minor hints that can lead to more costly repairs if ignored. Here are some of the most common warning signs to keep an eye on, whether you’re at home or running a business.
Water Draining Slowly
Water not draining like it used to? If your sink, bath, or shower’s lagging, that’s usually the early sign. In the kitchen, it’s cooking gunk. In the bathroom? The usual build-up are the usual suspects. If water’s sitting still, it’s time to do something about it.

Unpleasant Smells
If you’re noticing a pong coming from your sink, it usually means there’s something trapped where it shouldn’t be. Old food, fat, or even sewage can build up down there and start to rot. It’s best not to hope it goes away, a bad smell is often a sign that a blockage is already in the works.

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

Water Backing Up
One of the most apparent indicators of a blocked drain is water returning instead of draining. If you observe any sign of backflow, it’s important to act quickly to prevent it from escalating.
Toilet Flushing Poorly
If your toilet isn’t working right 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 items not meant for drains, like wipes, pads and tampons, or large amounts of toilet roll. It’s best to have it looked at before it gets worse.
Overflowing Outdoor Drains
Water pouring out of outside drains after rain? That’s a red flag. Might be a blockage underground. If water can’t get through, it comes out. That overflow? It can wreck gardens. Don’t wait, call it in.
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 cut it here. You’ll probably need a pro to inspect things with a camera and use jetting gear to shift the blockage.
Damp Patches or Mould
Drain problem? It’s not always obvious. Wet marks? Fungal growth? Smells near the skirting? That could be a hidden leak. Time to check it out.
