High-Pressure Water Jetting
Water jetting is our standard approach for resolving most drain blockages due to its speed, effectiveness, and versatility. Using specialised jetting equipment, we direct a powerful stream of water through the blocked area, removing common materials like grease, kitchen waste, and hair.
This method is also capable of cutting through more resilient blockages such as tree roots and hardened waste, making it ideal for situations where older methods are unsuccessful.

Water jetting’s the answer. Quick, tough, and doesn’t miss. We use water force to smash through grease, hair, food, and solid stuff. Nothing else cuts through it like this. Rods? Fine for minor blocks. Jetting? Built for the serious clogs.

Signs You Have a Blocked Drain
Not all drainage issues shout for attention. Many start with quiet symptoms that can lead to serious issues 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
When water takes longer to drain in your sink, bath, or shower, it’s often one of the early symptoms of a blockage developing. In kitchens, the most common culprits are fat and leftover food. In bathrooms, it’s often hair, soap, and mineral build-up. If water isn’t flowing out smoothly, it’s a good time to book an inspection before the issue grows bigger.

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

Gurgling Sounds From Pipes
Unfamiliar bubbling in your plumbing, especially fluid-like sounds, are often caused by air stuck in the system, which appears when water struggles to move by a blockage. If your pipes are gurgling oddly, it’s a good idea to get it inspected.

Water Backing Up
Water backing up? That’s a blocked drain. Don’t wait. handle it before it gets worse.
Toilet Flushing Poorly
If your toilet isn’t flushing right or is sluggish after a flush, there might be a problem in the pipe. It’s often down to stuff that didn’t belong, like wet wipes, feminine products, or just excess paper.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a problem. Might be a clog in the line. If water can’t get through, it backs up. That backup? It can undermine your foundation. Don’t risk it, get it sorted.
Multiple Fixtures Affected at Once
Multiple drains acting up? That’s not a minor fault. If toilets, sinks, and your washer are all blocked, the blockage is probably deep in the main line. Plunging won’t solve it. You need a camera check and powerful flushing to get it done right.
Damp Patches or Mould
Sometimes it starts with a scent. A musty hint near the cupboard. A soggy line curling across the base of a wall. Maybe even a fuzzy patch by the skirting. These quiet warnings often mean something hidden, a slow buildup, out of sight, slowly making its presence known.
