High-Pressure Water Jetting

Water jetting’s the fix. Fast, tough, and doesn’t miss. We use high-pressure hoses to smash through grease, hair, food, and roots. Nothing else does the job like this. Rods? Fine for minor blocks. Jetting? Built for the serious clogs.

Drain Jetting London

Water jetting is one of the most efficient ways to clear drain blockages. We use focused water jets to send water down the clogged area, breaking up everything from food waste and grease to hair and built-up grime. It’s also effective against deeper clogs like root systems and compacted debris: jobs that traditional rods often can’t manage.

Signs You Have a Blocked Drain

Not all drainage issues shout for attention. Many start with minor hints that can lead to bigger problems if ignored. Here are some of the most common red flags to keep an eye on, whether you’re at home or running a business.

Water Draining Slowly

If the water in your sink, bath, or shower is taking its time, that’s often your first clue. In the kitchen, it’s usually fat and food getting stuck. In the bathroom, it’s more likely hair and soap. Either way, if water’s lingering too long, it’s time to get it looked at.

Unblocked Sink

Unpleasant Smells

Persistent foul odours rising through your drains are a strong signal that debris, such as bits of leftover food, grease, or sewage, is accumulating where it can cause problems. These items can become lodged in your drains and begin to rot, releasing nasty gases. If you smell these odours near your indoor or outdoor drains, it’s likely that a blockage is already taking shape and should be addressed promptly.

Gurgling Sounds From Pipes

If your drains start making weird noises, it usually means air’s getting trapped because water’s struggling to pass. That often points to a problem in the system. If your pipes start sounding like a boiling kettle, it’s probably time to have it looked at.

what causes blocked drains

Water Backing Up

Water backing up instead of draining? That’s one of the big red flags. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t fix itself. Act fast, and we’ll make sure it’s gone fast.

Toilet Flushing Poorly

If your toilet won’t flush properly or takes ages to fill back up, there might be a clog in the drain. It’s often down to bits that block the pipe, like non-flushable wipes, sanitary bits, or just too much toilet paper.

Overflowing Outdoor Drains

Noticed water spilling from your outdoor drains when it rains? That might be more than just surface water, it could mean there’s a blockage underground that’s backing everything up. If left too long, all that overflow can even reach your house’s foundation. It’s smart to get help before it gets any worse.

Multiple Fixtures Affected at Once

Multiple drains backing up? That’s not a small issue. If toilets, sinks, and your washer are all backing up, the blockage is probably in the central drain. Plunging won’t cut it. You need a camera check and powerful flushing to sort it for good.

Damp Patches or Mould

A drainage issue isn’t always clear, but some signs can help you know what to look for. If you’ve noticed moist areas on the floor or wall, mould in places you wouldn’t expect, or a musty smell near kitchen units or skirting boards, it could mean a problem behind the scenes.
