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 high-pressure hoses, we send pressure down the pipe and clear out grease, old food, hair, and any gunk that’s sitting there. It’s even strong enough to take on bigger clogs, far more effective than using rods for the hard jobs.

CCTV Drain Surveys in St Helier
When a blockage proves persistent or difficult to diagnose, a CCTV drain survey provides a detailed inspection of your underground infrastructure. Rather than relying on disruptive methods or assumptions, we insert high-definition cameras that navigate through the pipes, delivering a continuous feed to our engineers. This process allows us to spot issues such as fractures, structural failure, root ingress, or severe waste build-up. With this information, we can identify the exact cause and location of the problem and recommend the best fix.

Signs You Have a Blocked Drain
While some drainage issues are immediately obvious, spotting early warning signs can help you prevent costly problems. Below is a guide of common indicators to watch for if you suspect a developing issue in your residence or business.
Water Draining Slowly
Water not going down right? If your sink, bath, or shower’s getting sluggish, that’s usually the big hint. 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 act.

Unpleasant Smells
Consistent bad smells rising through your drains are a strong signal that waste material, such as bits of leftover food, cooking oils, or organic sludge, is accumulating where it doesn’t belong. These items can become trapped within the pipework and begin to decompose, releasing offensive odours. If you smell these odours near your sink, shower, or external drainage, it’s likely that a blockage is already taking shape and should be looked at without delay.

Gurgling Sounds From Pipes
Drains noisy? That’s a warning. Usually means water’s fighting a blockage. If it sounds like a kettle, sort it.

Water Backing Up
Water rising instead of draining? That’s one of the clear warnings. A blocked drain is usually behind it. And trust me, if you’ve seen it once, it won’t get better on its own. Act fast, and we’ll make sure it’s sorted in no time.
Toilet Flushing Poorly
If your toilet isn’t flushing properly or takes a long time to refill, it could mean there’s a clog somewhere in the toilet line. These blockages are often caused by things that shouldn’t be flushed, like wipes, pads and tampons, or large amounts of toilet roll. It’s best to call in help before it gets worse.
Overflowing Outdoor Drains
Water pouring out of outside drains after rain? That’s a problem. Might be a serious backup. If water can’t get through, it backs up. That mess? It can crack driveways. Don’t delay, get it sorted.
Multiple Fixtures Affected at Once
If more than one drain’s acting up, like your toilet, sink, and bath all playing 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 help much here. You’ll want to get someone in to inspect things with a camera and clear it with pressure to shift the blockage.
Damp Patches or Mould
A drainage issue isn’t always obvious, but some signs can help you catch it early. If you’ve noticed wet spots on the floor or wall, unexpected fungal growth, or a musty smell near cupboards or along the baseboard, it could suggest a hidden leak or blockage.
