High-Pressure Water Jetting
Water jetting is one of the most reliable ways to clear drain blockages. We use high-pressure hoses to push fluid past the clogged area, shifting everything from food waste and grease to soap scum and organic matter. It’s also effective against hard-to-remove blockages like root systems and compacted debris, jobs that standard tools often can’t clear.

When it comes to unblocking pipes, we nearly always go for water jetting, it just does the trick. It’s fast, powerful, and sorts out most of the usual problems. With jetting gear, we blast through the pipe and break up grease, scraps, hair, and any gunk that’s sitting there. It’s even strong enough to take on tree roots, way better than using rods for the deep blockages.

Signs You Have a Blocked Drain
Sure, some drainage problems make themselves known fast. But most start small. Spot the early signs and you’ll stop it before it spreads. Check out this quick checklist if you think your drains might be playing up.
Water Draining Slowly
If the water in your sink, bath, or shower is draining slower than usual, that’s often your first clue. In the kitchen, it’s usually bits of cooking waste getting stuck. In the bathroom, it’s more likely soap scum and strands. Either way, if water’s not going anywhere fast, it’s time to call in a pro.

Unpleasant Smells
If you’re catching a nasty smell coming from your shower, it usually means there’s something trapped where it shouldn’t be. Old food, fat, or even sewage can sit in the pipes and go bad. It’s best not to hope it goes away, a bad smell is often a sign that a blockage is already getting started.

Gurgling Sounds From Pipes
Strange noises coming from your drains, particularly air-like noises, are often a sign that air pockets are forming. This typically occurs when water is struggling to move past a blockage, causing air flow issues. If your pipes begin making noises that sound like a boiling appliance, it’s wise to have them checked by a specialist.

Water Backing Up
Water not going down? That’s a blocked drain. Don’t put it off. handle it before it gets worse.
Toilet Flushing Poorly
A toilet that doesn’t flush properly or has a slow tank refill may suggest a blockage within the connected drainage system. These obstructions are often the result of foreign objects being flushed, common culprits include flushable wipes, feminine hygiene items, or excessive toilet paper.
Overflowing Outdoor Drains
Water pouring out of outside drains after rain? That’s a red flag. Might be a clog in the line. If water can’t get through, it overflows. That backup? It can undermine your foundation. Don’t wait, call it in.
Multiple Fixtures Affected at Once
If more than one fixture is sluggish, like your toilet, sink, and bath all backing up together, it’s probably not just a simple fix. When it’s in the main drain, even your washing machine can feel it. A quick go with a plunger won’t do the trick here. You’ll likely need someone to inspect things with a camera and clear it with pressure to shift the blockage.
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 strange growth. These early hints often mean something deeper, a leak or blockage, hiding underfoot, slowly coming to light.
