High-Pressure Water Jetting
Water jetting is one of the most reliable ways to clear drain blockages. We use specialist tools to push fluid past the clogged area, dislodging everything from common kitchen waste to soap scum and organic matter. It’s also effective against deeper clogs like root systems and compacted debris, jobs that standard tools often can’t clear.

Water jetting is one of the most efficient ways to clear drain blockages. We use specialist tools to push fluid past the clogged area, dislodging everything from food waste and grease to hair and built-up grime. It’s also effective against tougher obstructions like tree roots and compacted debris: jobs that traditional rods often can’t manage.

CCTV Drain Surveys in Islington
If a blockage keeps coming back, a CCTV drain survey helps us figure out what’s wrong inside the pipes. Instead of digging up your garden or trying things blindly, we thread a lens through the drain and get a good view. It shows us if there are cracks, wear, roots growing in, or a big old clog of waste. That way, we know where the problem sits and how to sort it.

Signs You Have a Blocked Drain
Not all drainage issues show up with a splash. Many start with small, easy-to-miss signs that can lead to bigger problems if ignored. Here are some of the most common things to look for to keep an eye on, whether you’re at home or running a business.
Water Draining Slowly
Water not moving? Any fixture, it’s the first sign of a blockage. In the kitchen, it’s fat and food. In the bathroom, soap and scale. Don’t wait. Fix it now.

Unpleasant Smells
If you’re gettin’ a bad whiff coming from your sink, it usually means there’s something trapped where it shouldn’t be. Old food, cooking muck, or even sewage can get caught and start to rot. It’s best not to ignore it, a bad smell is often a sign that a blockage is already in the works.

Gurgling Sounds From Pipes
Drains bubbling? That’s a sign of trouble. Usually means water’s fighting a blockage. If it sounds like a kettle, get it checked.

Water Backing Up
One of the easiest to spot indicators of a blocked drain is water rising back up. If you observe any sign of water backing up, it’s important to act quickly to prevent it from becoming more serious.
Toilet Flushing Poorly
If your toilet isn’t running smoothly or takes a long time to refill, it could mean there’s a problem somewhere in the soil pipe. These blockages are often caused by non-flushables, like baby wipes, sanitary products, or too much paper. It’s best to get it checked before it gets worse.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a warning sign. Might be a serious backup. If water can’t get through, it overflows. That overflow? It can undermine your foundation. Don’t delay, deal with it.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are struggling to empty simultaneously, it’s often indicative of a deeper issue within the main drain line. Such blockages can affect the function of everything from the toilet to the washing machine. In these cases, basic solutions like plunging are unlikely to be enough. A proper assessment using camera equipment, followed by professional jetting, is typically needed to locate and clear the obstruction.
Damp Patches or Mould
A drainage issue isn’t always obvious, but some signs can help you identify it quickly. If you’ve noticed moist areas on the floor or wall, unexpected fungal growth, or a mouldy odour near under the sink or along the baseboard, it could mean a hidden leak or blockage.
