We take a strong view against uncertainty and short-term fixes. Our qualified professionals use advanced equipment and reliable practices to get to the bottom of the issue and resolve it thoroughly. Below is an introduction of the main services we offer throughout Wandsworth.

High-Pressure Water Jetting

Water jetting is our go-to method for addressing most drain blockages due to its effectiveness, reliability, and wide use. Using powerful water streams, we direct a powerful stream of water through the obstructed section of pipe, breaking up common materials like grease, kitchen waste, and hair.

This method is also capable of breaking through more resilient blockages such as tree roots and hardened waste, making it highly suitable for situations where traditional drain rods are unsuccessful.

Water jetting’s the answer. Quick, solid, and gets through it all. We use jetting gear to smash through grease, hair, food, and roots. Nothing else cuts through it like this. Rods? Fine for minor blocks. Jetting? Built for the real ones.

CCTV Drain Surveys in Wandsworth

When a blockage keeps returning or difficult to diagnose, a CCTV drain survey provides a clear picture of your drainage system. Rather than relying on disruptive methods or trial and error, we insert high-definition cameras that travel the drain network, delivering live footage to our engineers. This process allows us to detect issues such as cracks, structural failure, root ingress, or severe waste build-up. With this footage, we can locate the exact cause and location of the problem and determine the best fix.

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 stop it before it spreads. Check out this quick checklist if you think your drains might be acting strange.

Water Draining Slowly

Water draining slow? Any fixture, it’s the first sign of a blockage. In the kitchen, it’s fat and food. In the bathroom, the usual suspects. Don’t wait. Sort it.

Unblocked Sink

Unpleasant Smells

Nasty whiff from a drain? That’s a trouble alert. Grease, sewage, or worse is probably rotting. Smell it near the outdoor drain? Don’t wait. A blockage is forming.

Gurgling Sounds From Pipes

If your drains start acting up with gurgles, it usually means air’s getting trapped because water’s hitting a blockage. That often points to a clog down the line. If your pipes start sounding like a boiling kettle, it’s probably time to have it looked at.

what causes blocked drains

Water Backing Up

A really clear sign your drain’s blocked is when water doesn’t go down like it should. If you see that, it’s a good idea to sort it before long before it turns into a bigger mess.

Toilet Flushing Poorly

Toilet not clearing or taking too long? Might be a plug in the soil pipe. Wipes, sanitary stuff, or too much paper usually to blame. Needs sorting.

Overflowing Outdoor Drains

If you observe water spilling from external drains during or after a storm, the issue may be more serious than 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 advised to minimise damage.

Multiple Fixtures Affected at Once

Multiple drains slowing down? That’s not a quick fix. If toilets, sinks, and your washer are all blocked, the blockage is probably deep in the main line. Plunging won’t cut it. You need a camera check and high-pressure water jetting to clear it properly.

Damp Patches or Mould

Drain problem? It’s not always obvious. Water stains? Fungal growth? Smells near the skirting? That could be a buried blockage. Get it looked at.

    Bang on time, job done fast.

    Turned up bang on time and were done quicker than expected. Cheers lads! Was expecting a drawn-out job, but they clearly knew what they were doing and just cracked on.

    Explained everything so simply.

    I had no clue what was going on with our pipes but they explained it all so clearly. Felt completely reassured the whole time and appreciated how patient they were with my questions.

    Down to earth and skilled.

    Really down-to-earth team who know what they’re doing. Cheers for the help. From the moment they turned up, it was clear we were in good hands. They made the whole process simple and stress-free.

    Didn’t let us down.

    They were recommended by a mate and didn’t disappoint. From the first phone call to the final clean-up, it was clear they knew their stuff. We felt confident we were in good hands the entire time.

    Surprisingly brilliant.

    Never thought I’d be raving about a drain company but here we are. They were just that good. Helpful, friendly, honest – and most importantly, they fixed the problem without any stress.

    Detailed and really useful.

    Had a CCTV survey done. Report was super detailed and made it easy for our builder.

  • 17/08/2025

    Garden sorted, no more flooding.

    Cheers to Clark Drainage for getting our garden sorted after that downpour. Great job. We’d tried a few things ourselves with no luck, but they came in, identified the issue quickly, and had the drainage working perfectly again.

  • 17/08/2025

    Quick turnaround and sorted fast.

    The lads came out next day and fixed the issue in half an hour. It had been bothering us for weeks, so to see it sorted that quickly was honestly a huge relief.

  • 16/08/2025

    Did it right first time.

    We’d had other companies round who couldn’t fix it. Clark Drainage had it sorted in one visit. The difference in professionalism and competence was night and day. Absolutely brilliant from start to finish.

  • 14/08/2025

    Proper pride in their work.

    It’s not glamorous work but they do it with a smile and real pride. Can’t say I’ve ever seen someone so happy clearing a drain, but they made the whole thing stress-free and even a bit fun.
