We take a clear position against guesswork and temporary solutions. Our qualified professionals use state-of-the-art technology and established techniques to identify the root cause and fix it long-term. Below is an outline of the key services we offer throughout Blackheath.
High-Pressure Water Jetting
Water jetting is our preferred technique for addressing most drain blockages due to its speed, thoroughness, and broad application. Using powerful water streams, we direct a concentrated jet of water through the affected drain, removing common materials like oils, food particles, and hair.
This method is also capable of breaking through more difficult clogs such as tree roots and solidified material, making it ideal for situations where traditional drain rods are ineffective.

Water jetting not only addresses the issue but also flushes the full interior of the pipe, minimising the risk of future issues. It’s a safe and non-invasive method for most drainage systems, and far less invasive than manual clearing or groundwork. Every one of our field units is equipped with high-powered jetting units, 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.
24/7 Emergency Drain Unblocking in Blackheath

CCTV Drain Surveys in Blackheath
When a blockage keeps returning or hard to pinpoint, a CCTV drain survey provides a clear picture of your pipes. Rather than relying on digging or guesswork, we deploy high-definition cameras that travel the drain network, delivering a continuous feed to our engineers. This process allows us to identify issues such as fractures, collapsed pipework, root ingress, or severe waste build-up. With this visual insight, we can identify the exact cause and location of the problem and determine the most effective solution.

Signs You Have a Blocked Drain
Sometimes drain problems are plain as day. Other times, you’ve got to catch the little signs early to avoid a proper mess. Here are some of the main things to look out for if you think something’s not right with your drains at your place.
Water Draining Slowly
Water not going down right? If your sink, bath, or shower’s getting sluggish, that’s usually the early sign. In the kitchen, it’s food and fat. In the bathroom? Bath muck are the common cause. If water’s not moving, it’s time to do something about it.

Unpleasant Smells
If you’re noticing a pong coming from your shower, it usually means something’s stuck where it shouldn’t be. Old food, grease, or even sewage can get caught and turn. It’s best not to ignore it, a bad smell is often a sign that a clog is already on the way.

Gurgling Sounds From Pipes
Strange noises in your plumbing, especially noises that rise and fall, are often caused by trapped air, which appears when water is slowed down by a blockage. If your pipes are making sounds like a kettle, it’s a good idea to get it checked early.

Water Backing Up
A pretty obvious clue your drain’s blocked is when water doesn’t go down like it should. If you notice it, it’s a good idea to get it looked at quickly before it gets worse.
Toilet Flushing Poorly
Toilet not emptying or taking too long? Might be a plug in the drain. Wipes, tampons, or toilet roll usually to blame. Call it in.
Overflowing Outdoor Drains
If you observe water spilling 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 overflow. Left unaddressed, this overflow can affect your landscape and foundation. Prompt attention is essential to prevent further complications.
Multiple Fixtures Affected at Once
If more than one thing’s draining slowly, like your toilet, sink, and bath all backing up together, it’s probably not just a small clog. When it’s in the main drain, everything gets affected. A quick go with a plunger won’t help much here. You’ll probably need a pro to inspect things with a camera and blast it with water to sort it properly.
Damp Patches or Mould
Sometimes it starts with a hint of something off. A musty hint near the cupboard. A damp streak gathering near the floor. Maybe even a strange growth. These early hints often mean something deeper, a drainage fault, hiding underfoot, slowly coming to light.
