Our Thornton Heath Drainage Services

Clark Drainage offers a comprehensive suite of professional drainage services for residential and commercial properties throughout Thornton Heath. From after-hours problems such as late-night plumbing issues to more involved tasks like complete system digs, our team is ready and prepared to respond at a moment’s notice.

We take a clear position against guesswork and quick patches. Our skilled technicians use state-of-the-art technology and proven methods to identify the root cause and fix it long-term. Below is an outline of the main services we offer throughout Thornton Heath.

High-Pressure Water Jetting

Water jetting is one of the most efficient ways to clear drain blockages. We use specialist tools to send water down the clogged area, shifting everything from food waste and grease to hair and built-up grime. It’s also effective against hard-to-remove blockages like root systems and hardened waste, jobs that standard tools often can’t manage.

Drain Jetting London

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 jetting gear, we send pressure down the pipe and blast away grease, scraps, hair, and the usual grime. It’s even strong enough to take on tree roots, far more effective than using rods for the tough stuff.

Signs You Have a Blocked Drain

Sure, some drainage problems make themselves known fast. But most creep up slowly. Spot the early signs and you’ll stop it before it spreads. Check out this handy guide if you think your drains might be getting blocked.

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, soap and scale. Don’t wait. Get it looked at.

Unblocked Sink

Unpleasant Smells

Foul odour from a drain? That’s a trouble alert. Food, sewage, or worse is probably rotting. Smell it near the outdoor drain? Don’t wait. A clog is forming.

Gurgling Sounds From Pipes

If your drains start acting up with gurgles, it usually means air is stuck in the pipe because water’s struggling to pass. That often points to a clog down the line. If your pipes are making odd bubbling noises, it’s probably time to have it looked at.

what causes blocked drains

Water Backing Up

A sure sign your drain’s blocked is when water rises back. If you spot that happening, it’s a good idea to get it looked at straight away before it turns into a bigger mess.

Toilet Flushing Poorly

If your toilet feels off when you flush or takes ages to fill back up, there might be a problem in the pipe. It’s often down to stuff that didn’t belong, like wet wipes, sanitary bits, or just excess paper.

Overflowing Outdoor Drains

Water pouring out of outside drains after rain? That’s a warning sign. Might be a serious backup. If water can’t get through, it overflows. That mess? It can wreck gardens. Don’t wait, deal with it.

Multiple Fixtures Affected at Once

Multiple drains slowing down? That’s not a minor fault. If toilets, sinks, and your washer are all affected, the blockage is probably deep in the main line. Plunging won’t solve it. You need a CCTV inspection and high-pressure water jetting to get it done right.

Damp Patches or Mould

Sometimes it starts with a hint of something off. A faint odour near the cupboard. A damp streak spreading in a corner. Maybe even a fuzzy patch by the skirting. These quiet warnings often mean something lurking, a leak or blockage, hiding underfoot, slowly doing damage.

    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.

    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.

    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.
