High-Pressure Water Jetting
Water jetting is one of the most effective ways to clear drain blockages.

It’s also effective against hard-to-remove blockages like tree roots and compacted debris, jobs that traditional rods often can’t reach.

CCTV Drain Surveys in Mill Hill
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 digging or trial and error, we navigate with high-definition cameras that travel the drain network, delivering a continuous feed to our engineers. This process allows us to identify issues such as fractures, collapsed pipework, tree intrusion, or severe waste build-up. With this visual insight, we can pinpoint the true source of the problem and plan the best fix.

Signs You Have a Blocked Drain
Sometimes drain problems are right in front of you. Other times, you’ve got to pay attention early to avoid a whole load of hassle. Here are some of the main things to keep in mind if you think something’s not right with your drains at your place.
Water Draining Slowly
If the water in your tub or sink is taking its time, that’s often your early warning. In the kitchen, it’s usually leftovers and grease getting stuck. In the bathroom, it’s more likely soap scum and strands. Either way, if water’s hanging around, it’s time to get someone to check it out.

Unpleasant Smells
If you’re noticing a pong coming from your shower, it usually means there’s something trapped where it shouldn’t be. Old food, grease, or worse can build up down there and start to rot. It’s best not to leave it, a bad smell is often a sign that a blockage is already on the way.

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

Water Backing Up
A pretty obvious clue your drain’s blocked is when water starts coming back up. If you see that, it’s a good idea to call someone in before long before it gets worse.
Toilet Flushing Poorly
Toilet not emptying or taking too long? Might be a clog in the soil pipe. Wipes, pads, or tissue usually to blame. Time to clear it out.
Overflowing Outdoor Drains
If you notice water spilling from external drains during or after heavy rain, the issue may extend beyond simple surface runoff. A significant underground blockage could be stopping water from flowing, causing water to overflow. Left untreated, this overflow can affect your landscape and foundation. Prompt attention is recommended to prevent further complications.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are slow to drain at the same time, it’s often a sign of a blockage within the primary drainage channel. Such obstructions can impact the function of everything from the toilet to the washing machine. In these scenarios, basic solutions like manual clearing are unlikely to be sufficient. A proper assessment using video diagnostics, followed by professional jetting, is typically needed to locate and clear the obstruction.
Damp Patches or Mould
Drain problem? It’s not always clear. Water stains? Dark patches? Stale odour under the sink? That could be a hidden leak. Get it looked at.
