Our Wandsworth Drainage Services
Clark Drainage offers a comprehensive suite of professional drainage services for homes and businesses throughout Wandsworth. From urgent issues such as late-night plumbing issues to more involved tasks like complete system digs, our team is ready and prepared to respond at any hour.
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.

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.

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.
