High-Pressure Water Jetting
Water jetting is our preferred technique for clearing most drain blockages due to its effectiveness, reliability, and wide use. Using high-pressure hoses, we direct a powerful stream of water through the blocked area, breaking up common materials like oils, kitchen waste, and organic buildup.
This method is also capable of breaking through more difficult clogs such as tree roots and solidified material, making it highly suitable for situations where traditional drain rods are ineffective.

When it comes to clearing drains, we nearly always go for water jetting, it just gets the job done. It’s quick, strong, and sorts out most of the regular issues. With jetting gear, we push water through the pipe and blast away grease, old food, hair, and the usual grime. It’s even strong enough to take on tree roots, far more effective than using rods for the tough stuff.

CCTV Drain Surveys in Upper Norwood
When a blockage isn’t straightforward or resists standard fixes, a CCTV drain survey provides a clear picture of your underground infrastructure. Rather than relying on excavation or guesswork, we insert high-definition cameras that navigate through the pipes, delivering live footage to our engineers. This process allows us to detect issues such as fractures, collapsed pipework, tree intrusion, or severe waste build-up. With this information, we can locate the true source of the problem and plan the right course of action.

Signs You Have a Blocked Drain
Sure, some drainage problems make themselves known fast. But most creep up slowly. Spot the early signs and you’ll stay ahead of the problem. Check out this list of common warning signs if you think your drains might be playing up.
Water Draining Slowly
Water draining slow? Sink, bath, or shower, it’s the early signal of a blockage. In the kitchen, it’s fat and food. In the bathroom, soap and scale. Don’t wait. Get it looked at.

Unpleasant Smells
That foul smell near the sink? That’s not just something in the air, it’s gunk building up, starting to break down. Food, grease, even sewage can get nasty. If you’re smelling something off, don’t ignore it. It means a drain issue is just starting, and it’s better to sort it quickly.

Gurgling Sounds From Pipes
If your drains start bubbling and gurgling, it usually means air is stuck in the pipe because water’s hitting a blockage. That often points to 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? That’s a blocked drain. Don’t put it off. Sort it before it gets worse.
Toilet Flushing Poorly
Toilet not flushing or taking too long? Might be a clog in the line. Wipes, sanitary stuff, or too much paper usually to blame. Time to clear it out.
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 preventing proper drainage, causing water to overflow. Left untreated, this overflow can lead to erosion, cracking, or structural issues. Prompt professional assessment is advised to avoid escalation.
Multiple Fixtures Affected at Once
If more than one drain’s acting up, like your toilet, sink, and bath all backing 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 cut it 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
Drain problem? It’s not always easy to spot. Damp on the floor or wall? Dark patches? Stale odour under the sink? That could be a buried blockage. Get it looked at.
