High-Pressure Water Jetting
Water jetting’s the answer. Fast, tough, and doesn’t miss. We use water force to cut into grease, hair, food, and roots. Nothing else does the job like this. Rods? Fine for easy stuff. Jetting? Built for the real ones.

Water jetting not only resolves the current blockage but also flushes the full interior of the pipe, reducing the risk of repeat blockages. It’s a low-impact approach for most drainage systems, and far less disruptive than mechanical rodding or digging. Every one of our field units is equipped with top-tier water jets, and our engineers are certified for safe use. In most cases, we can clear the blockage in a single visit without the need for further service.

This process allows us to spot issues such as cracks, collapsed pipework, tree intrusion, or severe waste build-up. With this footage, we can locate the exact cause and location of the problem and recommend the right course of action.

Signs You Have a Blocked Drain
Sometimes drain problems are easy to spot. Other times, you’ve got to notice the quiet hints to avoid a whole load of hassle. Here are some of the main things to spot early if you think something’s not right with your drains at home or work.
Water Draining Slowly
Slow drainage in common household drains is often the initial clue of a developing issue within your plumbing system. In kitchens, the culprit is frequently an accumulation of fat and food debris, while in bathrooms, it’s typically blockage from hair, soap, and scale. If water is taking longer than normal, it’s a good indicator the system should be assessed.

Unpleasant Smells
That foul smell near the shower? That’s not just something in the air, it’s waste stuck in your pipes, starting to break down. Food, grease, even sewage can get caught up. If you’re getting whiffs like that, don’t ignore it. It means a problem is on the move, and it’s better to get ahead of it.

Gurgling Sounds From Pipes
If your drains start bubbling and gurgling, it usually means air’s getting trapped because water’s not flowing properly. That often signals a blockage somewhere. If your pipes gurgle like a blocked sink, it’s probably time to have it looked at.

Water Backing Up
Water backing up instead of draining? That’s one of the big red flags. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t get better on its own. Call us in, and we’ll make sure it’s cleared quick.
Toilet Flushing Poorly
A toilet that doesn’t flush properly or has a slow tank refill may point to a clog within the connected drainage system. These blockages are often the result of non-flushable items being flushed, common culprits include disposable cloths, sanitary products, or large amounts of 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 comes out. That overflow? It can crack driveways. Don’t risk it, 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 jet gear to sort it for good.
Damp Patches or Mould
Sometimes it starts with a scent. A damp whiff near the cupboard. A dark patch gathering near the floor. Maybe even a fuzzy patch by the skirting. These early hints often mean something lurking, a drainage fault, out of sight, slowly doing damage.
