We take a strong view against guesswork and temporary solutions. Our skilled technicians use modern diagnostic tools and established techniques to identify the root cause and resolve it thoroughly. Below is an outline of the key services we offer throughout Frognal.
High-Pressure Water Jetting
Water jetting is one of the most reliable ways to clear drain blockages. We use high-pressure hoses to force water through the clogged area, shifting everything from food waste and grease to soap scum and organic matter. It’s also effective against deeper clogs like root systems and hardened waste, jobs that standard tools often can’t manage.

Water jetting is one of the most effective ways to clear drain blockages. We use focused water jets to push fluid past the clogged area, dislodging everything from common kitchen waste to hair and built-up grime. It’s also effective against hard-to-remove blockages like tree roots and hardened waste: jobs that standard tools often can’t clear.

CCTV Drain Surveys in Frognal

Signs You Have a Blocked Drain
Sometimes drain problems are easy to spot. Other times, you’ve got to pay attention early to avoid a whole load of hassle. Here are some of the main things to keep in mind if you think something’s not right with your drains at home or work.
Water Draining Slowly
Water not going down right? If your sink, bath, or shower’s lagging, that’s usually the big hint. In the kitchen, it’s food and fat. In the bathroom? Hair, soap, and scale are the usual suspects. If water’s just hanging out, it’s time to act.

Unpleasant Smells
If you’re noticing a pong coming from your outside drain, it usually means a bit of a problem’s brewing where it shouldn’t be. Old food, fat, or something grim can build up down there and turn. It’s best not to ignore it, a bad smell is often a sign that a problem is already in the works.

Gurgling Sounds From Pipes
Strange noises coming from your drains, particularly low bubbling sounds, are often a sign that air is trapped in the plumbing system. This typically occurs when water is unable to flow smoothly, causing air to be drawn in behind it. If your pipes begin making noises that sound like a boiling appliance, it’s recommended to have them professionally inspected.

Water Backing Up
A sure sign your drain’s blocked is when water starts coming back up. If you notice it, it’s a good idea to sort it straight away before it gets worse.
Toilet Flushing Poorly
If your toilet isn’t flushing right or is sluggish after a flush, there might be a problem in the pipe. It’s often down to stuff that didn’t belong, like non-flushable wipes, feminine products, or just too much toilet paper.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a problem. Might be a blockage underground. If water can’t get through, it comes out. That backup? It can undermine your foundation. Don’t wait, get it sorted.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are backing up at the same time, it’s often indicative of a system-level problem within the primary drainage channel. Such obstructions can disrupt the function of toilets, sinks, bathtubs, and even washing machines. In these scenarios, simple methods like manual clearing are unlikely to be enough. A proper assessment using camera equipment, followed by high-pressure water jetting, is typically needed to get rid of the obstruction.
Damp Patches or Mould
Drain problem? It’s not always easy to spot. Wet marks? Fungal growth? Smells near the skirting? That could be a pipe issue. Don’t leave it long.
