High-Pressure Water Jetting
When it comes to clearing drains, we nearly always go for water jetting, it just works. It’s quick, powerful, and sorts out most of the common clogs. With high-pressure hoses, we blast through the pipe and break up grease, scraps, hair, and whatever else has built up. It’s even strong enough to take on tree roots, way better than using rods for the deep blockages.

Water jetting not only resolves the current blockage but also flushes the full diameter of the pipe, reducing the risk of repeat blockages. It’s a gentle yet effective solution for most drainage systems, and far less damaging than mechanical rodding or groundwork. Every one of our service vehicles is equipped with advanced jetting systems, and our engineers are trained to operate them with precision and safety. In most cases, we can resolve the problem in a single visit without the need for follow-up work.

Signs You Have a Blocked Drain
Not all drainage issues are obvious from the start. Many start with minor hints that can lead to serious issues if ignored. Here are some of the most common things to look for to keep an eye on, whether you’re at your property or your workplace.
Water Draining Slowly
Water draining sluggishly in sinks, bathtubs, or showers is often the first sign of a developing issue within your plumbing system. In kitchens, the cause is frequently an accumulation of fat and food debris, while in bathrooms, it’s typically mineral and organic deposits. If water is lingering, it’s a strong hint the system should be checked.

Unpleasant Smells
Consistent bad smells emanating from your drains are a clear indicator that debris, such as bits of leftover food, fats, or wastewater, is getting trapped where it shouldn’t. These items can become lodged in your drains and begin to decompose, releasing offensive odours. If you smell these odours near your indoor or outdoor drains, it’s likely that a blockage is forming and should be addressed promptly.

Gurgling Sounds From Pipes
Unfamiliar bubbling in your plumbing, especially fluid-like sounds, are often caused by trapped air, which builds up when water can’t pass 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
One of the clearest indicators of a blocked drain is water reversing direction. If you see any sign of reverse flow, it’s important to address the issue promptly to prevent it from developing further.
Toilet Flushing Poorly
Toilet not emptying or taking too long? Might be a clog in the drain. Wet wipes, tampons, or tissue usually to blame. Needs sorting.
Overflowing Outdoor Drains
Water rising up in outside drains after rain? That’s a red flag. Might be a clog in the line. If water can’t get through, it backs up. That mess? It can crack driveways. Don’t wait, get it sorted.
Multiple Fixtures Affected at Once
If more than one drain’s acting up, like your toilet, sink, and bath all playing up together, it’s probably not just a minor blockage. When it’s in the main drain, everything gets affected. A quick go with a plunger won’t help much here. You’ll want to get someone in to have a check with a camera and clear it with pressure to get things moving again.
Damp Patches or Mould
Hidden blockages can creep in. One day everything’s fine, then boom, wet walls, stuff growing where it shouldn’t, or a funky smell near the skirting board. If it doesn’t seem right, it probably is. And we are ready to fix it.
