High-Pressure Water Jetting
When it comes to getting drains moving, we nearly always go for water jetting, it just gets the job done. It’s fast, strong, and sorts out most of the usual problems. With high-pressure hoses, we send pressure down the pipe and break up grease, old food, hair, and the usual grime. It’s even strong enough to take on bigger clogs, way better than using rods for the hard jobs.

Water jetting is one of the most efficient ways to clear drain blockages. We use focused water jets to force water through the clogged area, shifting everything from food waste and grease to hair and built-up grime. It’s also effective against tougher obstructions like tree roots and hardened waste: jobs that standard tools often can’t manage.

CCTV Drain Surveys in Greenwich
If a blockage won’t stay gone, a CCTV drain survey helps us see exactly what’s going on inside the pipes. Instead of tearing things up or making assumptions, we thread a lens through the drain and have a nosey. It shows us if there are breaks, wear, roots growing in, or a big old pile of gunk. That way, we know where the problem sits and where to fix it.

Signs You Have a Blocked Drain
While some drainage issues show clear symptoms, spotting early warning signs can help you intervene before it escalates. Below is a list of common indicators to look out for if you suspect a developing issue in your house or workplace.
Water Draining Slowly
If the water in your tub or sink is taking its time, that’s often your sign something’s up. In the kitchen, it’s usually fat and food getting stuck. In the bathroom, it’s more likely soap scum and strands. Either way, if water’s hanging around, it’s time to call in a pro.

Unpleasant Smells
If you’re catching a nasty smell coming from your sink, it usually means there’s something trapped where it shouldn’t be. Old food, grease, or something grim can get caught and start to rot. It’s best not to leave 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 air-like noises, are often a sign that air pockets are forming. This typically occurs when water is disrupted by an obstruction, causing air to be drawn in behind it. If your pipes begin making noises similar to a blocked plughole, it’s recommended to have them looked at promptly.

Water Backing Up
Water backing up? That’s a blocked drain. Don’t put it off. get it fixed before it gets worse.
Toilet Flushing Poorly
If your toilet isn’t flushing right or takes ages to fill back up, there might be a problem in the pipe. It’s often down to bits that block the pipe, like wet wipes, sanitary bits, or just a wad of tissue.
Overflowing Outdoor Drains
Had water bubbling up 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 blocking the flow. If left too long, all that overflow can start damaging your garden. Best to get someone in before it gets any worse.
Multiple Fixtures Affected at Once
When multiple outlets in your property are slow to drain at the same time, it’s often linked to a system-level problem within the primary drainage channel. Such clogs can affect the function of several fixtures at once. In these scenarios, quick fixes like home tools are unlikely to be enough. A thorough investigation using camera equipment, followed by high-pressure water jetting, is typically required to identify and eliminate the obstruction.
Damp Patches or Mould
Sometimes it starts with a smell. A damp whiff near the cupboard. A soggy line gathering near the floor. Maybe even mould in a place you’d never expect it. These quiet warnings often mean something deeper, a slow buildup, tucked away behind the plaster, slowly doing damage.
