Our Mortlake Drainage Services
Clark Drainage is here for it all. From the late-night stress of a toilet that backs up at midnight to the serious business of digging out and replacing a broken drain, we’re always there. Across Mortlake, in homes and businesses alike, we’re the team you can turn to, no matter the hour.
We take a clear position against trial-and-error and temporary solutions. Our skilled technicians use advanced equipment and proven methods to identify the root cause and resolve it thoroughly. Below is an introduction of the main services we deliver throughout Mortlake.
High-Pressure Water Jetting
Water jetting’s the way. Fast, solid, and works nearly every time. We use water force to smash through grease, hair, food, and solid stuff. Nothing else cuts through it like this. Rods? Fine for easy stuff. Jetting? Built for the real ones.

Water jetting not only resolves the current blockage but also thoroughly cleans the full width of the pipe, minimising the risk of repeat blockages. It’s a low-impact approach for most drainage systems, and far less disruptive than mechanical rodding or groundwork. Every one of our field units is equipped with high-powered jetting units, and our engineers are certified for safe use. In most cases, we can complete the job in a single visit without the need for further service.
24/7 Emergency Drain Unblocking in Mortlake

CCTV Drain Surveys in Mortlake
If a blockage is recurring or won’t fully clear, a CCTV survey is the best way to understand the problem inside your drains. We send in a small, high-definition camera into the system, allowing us to inspect the interior without disruption. This footage helps us highlight breaks, tree growth, blockages, or sections that have failed, so we can target the cause and choose the most efficient fix.

Across Mortlake, we support businesses with professional flushing, CCTV diagnostics, and flexible scheduling to keep business running.

Signs You Have a Blocked Drain
While some drainage issues show clear symptoms, identifying early warning signs can help you prevent costly problems. Below is a guide of common indicators to look out for if you suspect a drainage problem in your home or commercial property.
Water Draining Slowly
Water not going down right? 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? Hair, soap, and scale are the usual suspects. If water’s not moving, it’s time to jump on it.

Unpleasant Smells
Consistent bad smells coming from your drains are a reliable sign that debris, such as bits of leftover food, grease, or sewage, is building up where it can cause problems. These substances can become stuck deep in the system and begin to decompose, releasing offensive odours. If you notice these odours near your kitchen or bathroom fixtures, it’s likely that a blockage is already taking shape and should be looked at without delay.

Gurgling Sounds From Pipes
Strange noises in your plumbing, especially gurgling or bubbling, are often caused by air stuck in the system, which appears when water can’t pass by a blockage. If your pipes are bubbling like a blocked sink, it’s a good idea to get it inspected.

Water Backing Up
Water backing up? That’s a blocked drain. Don’t stall. get it fixed before it causes damage.
Toilet Flushing Poorly
A toilet that fails to flush effectively or refills unusually slowly may suggest a restriction within the main toilet pipe. These issues are often the result of non-flushable items being flushed, common culprits include flushable wipes, sanitary products, or large amounts of paper.
Overflowing Outdoor Drains
Had water spilling from your outdoor drains when it rains? That might be a sign of something worse, it could mean there’s a blockage underground that’s backing everything up. If left too long, all that overflow can mess with your driveway. Best to get someone in before it turns into a bigger problem.
Multiple Fixtures Affected at Once
If more than one fixture is sluggish, like your toilet, sink, and bath all being weird at the same time, it’s probably not just a small clog. When it’s in the main drain, even your washing machine can feel it. A quick go with a plunger won’t do the trick here. You’ll probably need a pro to inspect things with a camera and clear it with pressure to get things moving again.
Damp Patches or Mould
Sometimes it starts with a hint of something off. A faint odour near the cupboard. A damp streak gathering near the floor. Maybe even a fuzzy patch by the skirting. These early hints often mean something hidden, a slow buildup, out of sight, slowly coming to light.
