High-Pressure Water Jetting
Water jetting is our go-to method for resolving most drain blockages due to its efficiency, reliability, and broad application. Using specialised jetting equipment, we direct a concentrated jet of water through the obstructed section of pipe, breaking up common materials like grease, food particles, and organic buildup.
This method is also capable of cutting through more resilient blockages such as root intrusions and solidified material, making it ideal for situations where older methods are unsuccessful.

Water jetting’s the way. Quick, solid, and gets through it all. We use high-pressure hoses to blast apart grease, hair, food, and roots. Nothing else clears it out like this. Rods? Fine for minor blocks. Jetting? Built for the heavy stuff.

CCTV Drain Surveys in Crouch End
If a blockage keeps coming back, a CCTV drain survey helps us get to the bottom of it inside the pipes. Instead of tearing things up or guessing, we pop a camera down the drain and take a proper look. It shows us if there are cracks, damage, roots growing in, or a big old pile of gunk. That way, we know where the problem sits and what to do next.

Signs You Have a Blocked Drain
Sure, some drainage problems are impossible to miss. But most begin quietly. Spot the early signs and you’ll stay ahead of the problem. Check out this quick checklist if you think your drains might be playing up.
Water Draining Slowly
Water not moving like before? If your sink, bath, or shower’s feeling slow, that’s usually the early sign. In the kitchen, it’s leftovers building up. In the bathroom? The usual build-up are the biggest offenders. If water’s sitting still, it’s time to act.

Unpleasant Smells
Persistent foul odours emanating from your drains are a clear indicator that debris, such as kitchen waste, grease, or sewage, is building up where it can cause problems. These materials can become trapped within the pipework and begin to break down, releasing offensive odours. If you notice these odours near your kitchen or bathroom fixtures, it’s likely that a blockage is developing and should be looked at without delay.

Gurgling Sounds From Pipes
Drains bubbling? That’s a sign of trouble. Usually means water’s pushing past something. If it sounds like a blocked sink, get it checked.

Water Backing Up
Water coming back up? That’s a blocked drain. Don’t wait. get it fixed before it goes further.
Toilet Flushing Poorly
If your toilet isn’t working right or struggles to reset, it could mean there’s a clog somewhere in the soil pipe. These blockages are often caused by things that shouldn’t be flushed, like wipes, hygiene items, or too much paper. It’s best to have it looked at before it gets worse.
Overflowing Outdoor Drains
If you see water spilling from external drains during or after heavy rain, the issue may go deeper than simple surface runoff. A significant underground blockage could be disrupting flow, causing water to back up. Left ignored, this overflow can affect your landscape and foundation. Prompt attention is recommended to prevent further complications.
Multiple Fixtures Affected at Once
When multiple outlets in your property are slow to drain simultaneously, it’s often indicative of a blockage within the main drain line. Such clogs can disrupt the function of toilets, sinks, bathtubs, and even washing machines. In these scenarios, simple methods like home tools are unlikely to be sufficient. A proper assessment using CCTV technology, followed by high-pressure water jetting, is typically recommended to locate and clear the obstruction.
Damp Patches or Mould
Sometimes it starts with a hint of something off. A musty hint near the cupboard. A damp streak curling across the base of a wall. Maybe even mould in a place you’d never expect it. These early hints often mean something hidden, a slow buildup, hiding underfoot, slowly making its presence known.
