High-Pressure Water Jetting
Water jetting is one of the most effective ways to clear drain blockages. We use focused water jets to send water down the clogged area, dislodging 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 standard tools often can’t reach.

When it comes to clearing drains, we nearly always go for water jetting, it just gets the job done. It’s fast, strong, and sorts out most of the regular issues. With high-pressure hoses, we send pressure down the pipe and blast away grease, old food, hair, and any gunk that’s sitting there. It’s even strong enough to take on tougher blockages, way better than using rods for the hard jobs.

CCTV Drain Surveys in Erith
If a blockage is recurring or persists, a CCTV survey is the best way to find out what’s happening inside your drains. We thread a small, high-definition camera into the system, which lets us check the full layout without removing anything. This footage helps us identify damage, root intrusion, clogs, or pipe collapse, so we can pinpoint the issue and choose the most efficient fix.

Signs You Have a Blocked Drain
While some drainage issues show clear symptoms, being able to recognise early warning signs can help you prevent costly problems. Below is a list of common indicators to watch for if you suspect a potential blockage in your house or workplace.
Water Draining Slowly
Delayed water flow in sinks, bathtubs, or showers is often the first sign of a developing issue within your plumbing system. In kitchens, the reason is frequently buildup from grease and scraps, while in bathrooms, it’s typically blockage from hair, soap, and scale. If water is lingering, it’s a clear sign the system should be checked.

Unpleasant Smells
Bad smell from a drain? That’s a warning sign. Waste, sewage, or worse is probably trapped. Smell it near the shower? Don’t wait. A mess is forming.

Gurgling Sounds From Pipes
Unusual sounds coming from your drains, particularly gurgling or bubbling, 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 wise to have them checked by a specialist.

Water Backing Up
Water flooding back instead of draining? That’s one of the clear warnings. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t clear up without help. Act fast, and we’ll make sure it’s cleared quick.
Toilet Flushing Poorly
If your toilet feels off when you flush or is sluggish after a flush, there might be a clog in the drain. It’s often down to stuff that didn’t belong, like baby wipes, pads and tampons, or just excess paper.
Overflowing Outdoor Drains
If you see water overflowing out of external drains during or after a storm, the issue may extend beyond simple surface runoff. A minor or full underground blockage could be disrupting flow, causing water to overflow. Left ignored, this overflow can lead to erosion, cracking, or structural issues. Prompt attention is recommended to prevent further complications.
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, the whole system gets hit. A quick go with a plunger won’t cut it here. You’ll likely need someone to have a check with a camera and blast it with water to get things moving again.
Damp Patches or Mould
Sometimes it starts with a smell. A musty hint near the cupboard. A soggy line spreading in a corner. Maybe even a strange growth. These early hints often mean something deeper, a slow buildup, out of sight, slowly making its presence known.
