High-Pressure Water Jetting
Water jetting is one of the most efficient ways to clear drain blockages. We use focused water jets to force water through the clogged area, breaking up everything from food waste and grease to soap scum and organic matter. It’s also effective against deeper clogs like root systems and hardened waste, jobs that standard tools often can’t reach.

Water jetting’s the fix. Quick, tough, and gets through it all. We use jetting gear to smash through grease, hair, food, and solid stuff. Nothing else does the job like this. Rods? Fine for easy stuff. Jetting? Built for the serious clogs.

Signs You Have a Blocked Drain
While some drainage issues show clear symptoms, spotting early warning signs can help you prevent costly problems. Below is a list of common indicators to watch for if you suspect a potential blockage in your home or commercial property.
Water Draining Slowly
Slow drainage in sinks, bathtubs, or showers is often the initial clue of a forming blockage within your plumbing system. In kitchens, the cause is frequently buildup from grease and scraps, while in bathrooms, it’s typically blockage from hair, soap, and scale. If water is sitting, it’s a good indicator the system should be assessed.

Unpleasant Smells
That rotten whiff near the drain? That’s not just something in the air, it’s stuff left behind, starting to break down. Food, grease, even sewage can get nasty. If you’re smelling something off, don’t ignore it. It means a problem is on the move, and it’s better to sort it quickly.

Gurgling Sounds From Pipes
Strange noises in your plumbing, especially gurgling or bubbling, are often caused by trapped air, which forms when water is slowed down by a blockage. If your pipes are bubbling like a blocked sink, it’s a good idea to have a professional take a look.

Water Backing Up
Water not going down? That’s a blocked drain. Don’t put it off. Sort it before it causes damage.
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 non-flushable wipes, pads and tampons, or just a wad of tissue.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a red flag. Might be a blockage underground. If water can’t get through, it overflows. That mess? It can wreck gardens. Don’t delay, get it sorted.
Multiple Fixtures Affected at Once
When different parts of your plumbing in your property are backing up at the same time, it’s often indicative of a blockage within the primary drainage channel. Such blockages can affect the function of toilets, sinks, bathtubs, and even washing machines. In these cases, quick fixes like home tools are unlikely to be sufficient. A proper assessment using CCTV technology, followed by power flushing, is typically recommended to locate and clear the obstruction.
Damp Patches or Mould
A drainage issue isn’t always clear, but some signs can help you identify it quickly. If you’ve noticed damp patches on the floor or wall, mould in places you wouldn’t expect, or a musty smell near kitchen units or floor edges, it could suggest a hidden leak or blockage.
