Our Frognal Drainage Services

Clark Drainage is here for it all. From the quiet panic of a toilet that won’t flush at midnight to the serious business of digging out and replacing a broken drain, we’re always there. Across Frognal, in homes and businesses alike, we’re the team you can count on, no matter the hour.

We take a strong view against guesswork and temporary solutions. Our skilled technicians use modern diagnostic tools and established techniques to identify the root cause and resolve it thoroughly. Below is an outline of the key services we offer throughout Frognal.

High-Pressure Water Jetting

Water jetting is one of the most reliable ways to clear drain blockages. We use high-pressure hoses 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 standard tools often can’t manage.

Drain Jetting London

Water jetting is one of the most effective ways to clear drain blockages. We use focused water jets to push fluid past the clogged area, dislodging everything from common kitchen waste to hair and built-up grime. It’s also effective against hard-to-remove blockages like tree roots and hardened waste: jobs that standard tools often can’t clear.

CCTV Drain Surveys in Frognal

If a blockage is stubborn or keeps returning, a CCTV survey is the best way to find out what’s happening inside your drains. We thread a small, high-definition camera into the system, allowing us to inspect the interior without digging. This footage helps us spot breaks, root intrusion, blockages, or pipe collapse, so we can pinpoint the issue and fix it right the first time.

Signs You Have a Blocked Drain

Sometimes drain problems are easy to spot. 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 home or work.

Water Draining Slowly

Water not going down right? If your sink, bath, or shower’s lagging, that’s usually the big hint. In the kitchen, it’s food and fat. In the bathroom? Hair, soap, and scale are the usual suspects. If water’s just hanging out, it’s time to act.

Unblocked Sink

Unpleasant Smells

If you’re noticing a pong coming from your outside drain, it usually means a bit of a problem’s brewing where it shouldn’t be. Old food, fat, or something grim can build up down there and turn. It’s best not to ignore it, a bad smell is often a sign that a problem is already in the works.

Gurgling Sounds From Pipes

Strange noises coming from your drains, particularly low bubbling sounds, are often a sign that air is trapped in the plumbing system. This typically occurs when water is unable to flow smoothly, causing air to be drawn in behind it. If your pipes begin making noises that sound like a boiling appliance, it’s recommended to have them professionally inspected.

Water Backing Up

A sure sign your drain’s blocked is when water starts coming back up. If you notice it, it’s a good idea to sort it straight away before it gets worse.

Toilet Flushing Poorly

If your toilet isn’t flushing right or is sluggish after a flush, there might be a problem in the pipe. It’s often down to stuff that didn’t belong, like non-flushable wipes, feminine products, or just too much toilet paper.

Overflowing Outdoor Drains

Water spilling from outside drains after rain? That’s a problem. Might be a blockage underground. If water can’t get through, it comes out. That backup? It can undermine your foundation. Don’t wait, get it sorted.

Multiple Fixtures Affected at Once

When several plumbing fixtures in your property are backing up at the same time, it’s often indicative of a system-level problem within the primary drainage channel. Such obstructions can disrupt the function of toilets, sinks, bathtubs, and even washing machines. In these scenarios, simple methods like manual clearing are unlikely to be enough. A proper assessment using camera equipment, followed by high-pressure water jetting, is typically needed to get rid of the obstruction.

Damp Patches or Mould

Drain problem? It’s not always easy to spot. Wet marks? Fungal growth? Smells near the skirting? That could be a pipe issue. Don’t leave it long.

    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.

    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.

    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.

    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.
