We take a strong view against guesswork and short-term fixes. Our skilled technicians use modern diagnostic tools and established techniques to identify the root cause and fix it long-term. Below is an outline of the core services we deliver throughout New Addington.
High-Pressure Water Jetting
When it comes to unblocking pipes, we nearly always go for water jetting, it just does the trick. It’s quick, strong, and sorts out most of the common clogs. With jetting gear, we push water through the pipe and blast away grease, scraps, hair, and the usual grime. It’s even strong enough to take on tougher blockages, much stronger than using rods for the hard jobs.

Water jetting not only addresses the issue but also washes out the full interior of the pipe, significantly lowering the risk of future issues. It’s a low-impact approach for most drainage systems, and far less damaging than traditional tools or digging. Every one of our field units is equipped with advanced jetting systems, 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.

CCTV Drain Surveys in New Addington
If a blockage is recurring or won’t fully clear, a CCTV survey is the best way to understand the problem inside your drains. We send in a small, high-definition camera into the system, allowing us to inspect the interior without digging. This footage helps us identify damage, root intrusion, clogs, or sections that have failed, so we can target the cause and choose the most efficient fix.

Across New Addington, we support businesses with jet-powered cleaning, real-time surveys, and appointments planned around your hours to minimise interruption.

Signs You Have a Blocked Drain
Not all drainage issues are obvious from the start. Many start with quiet symptoms that can lead to more costly repairs if ignored. Here are some of the most common warning signs to keep an eye on, whether you’re at the house or managing a site.
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 forming. In kitchens, the most common culprits are fat and leftover food. In bathrooms, it’s often hair, soap, and mineral build-up. If water isn’t flowing out smoothly, it’s a good time to book an inspection before the issue causes problems.

Unpleasant Smells
That nasty scent near the sink? That’s not just something in the air, it’s stuff left behind, starting to rot. Food, grease, even sewage can get nasty. If you’re picking up a stink, don’t ignore it. It means a blockage is on the move, and it’s better to get ahead of it.

Gurgling Sounds From Pipes
If your drains start bubbling and gurgling, it usually means the system’s got air where it shouldn’t be because water’s hitting a blockage. That often means a blockage somewhere. If your pipes start sounding like a boiling kettle, it’s probably time to call someone in.

Water Backing Up
One of the most apparent indicators of a blocked drain is water reversing direction. If you observe any sign of backflow, it’s important to act quickly to prevent it from developing further.
Toilet Flushing Poorly
Toilet not clearing or filling slow? Might be a blockage in the line. Wipes, pads, or too much paper usually to blame. Needs sorting.
Overflowing Outdoor Drains
If you observe water spilling from external drains during or after rainfall, the issue may be more serious than simple surface runoff. A partial or complete underground blockage could be stopping water from flowing, causing water to overflow. Left untreated, this overflow can lead to erosion, cracking, or structural issues. Prompt professional assessment is advised to prevent further complications.
Multiple Fixtures Affected at Once
If more than one drain’s acting up, like your toilet, sink, and bath all being weird at the same time, 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 help much here. You’ll likely need someone to take a proper look with a camera and use jetting gear to get things moving again.
Damp Patches or Mould
Sometimes it starts with a scent. A damp whiff near the cupboard. A dark patch curling across the base of a wall. Maybe even mould in a place you’d never expect it. These subtle signs often mean something lurking, a leak or blockage, out of sight, slowly coming to light.
