No messing around. No short-term fixes. Our engineers are experienced. The gear is the real deal. We find the problem. We fix it properly. Here’s what we do in Waltham Forest.
High-Pressure Water Jetting
Water jetting is one of the most effective 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 soap scum and organic matter. It’s also effective against deeper clogs like root systems and hardened waste, jobs that traditional rods often can’t reach.

When it comes to clearing drains, we nearly always go for water jetting, it just does the trick. It’s fast, powerful, and sorts out most of the usual problems. With high-pressure hoses, we blast through the pipe and clear out grease, old food, hair, and any gunk that’s sitting there. It’s even strong enough to take on tougher blockages, much stronger than using rods for the tough stuff.

Signs You Have a Blocked Drain
Not all drainage issues show up with a splash. Many start with quiet symptoms that can lead to more costly repairs if ignored. Here are some of the most common red flags to keep an eye on, whether you’re at home or running a business.
Water Draining Slowly
Water not moving like before? If your sink, bath, or shower’s getting sluggish, that’s usually the big hint. In the kitchen, it’s leftovers building up. In the bathroom? Hair, soap, and scale are the biggest offenders. If water’s just hanging out, it’s time to act.

Unpleasant Smells
Nasty whiff from a drain? That’s a trouble alert. Waste, gunk, or worse is probably trapped. Smell it near the outdoor drain? Don’t wait. A clog is forming.

Gurgling Sounds From Pipes
Odd gurgling coming from your drains, particularly gurgling or bubbling, are often a sign that there’s air in the line. This typically occurs when water is struggling to move past a blockage, causing air to be drawn in behind it. If your pipes begin making noises reminiscent of a kettle, it’s recommended to have them checked by a specialist.

Water Backing Up
One of the clearest indicators of a blocked drain is water rising back up. If you observe any sign of water backing up, it’s important to get it looked at to prevent it from becoming more serious.
Toilet Flushing Poorly
If your toilet isn’t flushing right or seems slow to refill, there might be a problem in the pipe. It’s often down to things that shouldn’t have been flushed, like wet wipes, sanitary bits, or just a wad of tissue.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a red flag. Might be a serious backup. If water can’t get through, it overflows. That mess? It can undermine your foundation. Don’t risk it, deal with it.
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 simple fix. When it’s in the main drain, even your washing machine can feel it. A quick go with a plunger won’t help much here. You’ll probably need a pro to take a proper look with a camera and blast it with water to sort it properly.
Damp Patches or Mould
Sometimes it starts with a hint of something off. A damp whiff near the cupboard. A damp streak gathering near the floor. Maybe even a strange growth. These quiet warnings often mean something hidden, a slow buildup, hiding underfoot, slowly doing damage.
