High-Pressure Water Jetting
Water jetting is our standard approach for addressing most drain blockages due to its speed, effectiveness, and wide use. Using powerful water streams, we direct a concentrated jet of water through the affected drain, dislodging common materials like grease, food particles, and organic buildup.
This method is also capable of breaking through more difficult clogs such as tree roots and hardened waste, making it highly suitable for situations where traditional drain rods are unsuccessful.
Water jetting not only resolves the current blockage but also thoroughly cleans the full width of the pipe, significantly lowering the risk of repeat blockages. It’s a low-impact approach for most drainage systems, and far less invasive than mechanical rodding or digging. Every one of our field units is equipped with high-powered jetting units, and our engineers are fully qualified to use them correctly. In most cases, we can resolve the problem in a single visit without the need for additional intervention.

Signs You Have a Blocked Drain
Sure, some drainage problems make themselves known fast. But most begin quietly. Spot the early signs and you’ll save yourself a ton of bother. Check out this quick checklist if you think your drains might be acting strange.
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 starting to build. In kitchens, the most common culprits are fat and leftover food. In bathrooms, it’s often soap residue and strands. If water isn’t flowing out smoothly, it’s a good time to get help before the issue causes problems.

Unpleasant Smells
Unpleasant drain scents rising through your drains are a clear indicator that waste material—such as kitchen waste, fats, or wastewater—is building up where it shouldn’t. These items can become trapped within the pipework and begin to rot, releasing offensive odours. If you notice these odours near your kitchen or bathroom fixtures, it’s likely that a blockage is forming and should be looked at without delay.
Gurgling Sounds From Pipes
Drains gurgling? That’s trapped air. Usually means water’s not flowing. 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 see any sign of backflow, it’s important to act quickly to prevent it from escalating.
Toilet Flushing Poorly
A toilet that fails to flush effectively or has a slow tank refill may suggest a clog within the main toilet pipe. These obstructions are often the result of non-flushable items being flushed—common culprits include flushable wipes, tampons or pads, or excessive toilet paper.
Overflowing Outdoor Drains
If you notice water emerging from external drains during or after heavy rain, the issue may be more serious than simple surface runoff. A minor or full underground blockage could be stopping water from flowing, causing water to accumulate. Left ignored, this overflow can lead to erosion, cracking, or structural issues. Prompt intervention is advised to avoid escalation.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are backing up at the same time, it’s often a sign of a deeper issue within the primary drainage channel. Such blockages can impact the function of toilets, sinks, bathtubs, and even washing machines. In these cases, basic solutions like plunging are unlikely to be enough. A proper assessment using camera equipment, followed by professional jetting, is typically required to locate and clear the obstruction.
Damp Patches or Mould
A drainage issue isn’t always obvious, but some signs can help you catch it early. If you’ve noticed damp patches on the floor or wall, unexpected fungal growth, or a musty smell near cupboards or along the baseboard, it could suggest a drainage issue.
