CCTV Drain Surveys in Kings Cross
When a blockage isn’t straightforward or resists standard fixes, a CCTV drain survey provides a detailed inspection of your pipes. Rather than relying on disruptive methods or trial and error, we deploy high-definition cameras that navigate through the pipes, delivering a continuous feed to our engineers. This process allows us to identify issues such as cracks, collapsed pipework, tree intrusion, or excess residue. With this footage, we can pinpoint the true source of the problem and plan the right course of action.

Signs You Have a Blocked Drain
Not all drainage issues are obvious from the start. Many start with small, easy-to-miss signs that can lead to serious issues if ignored. Here are some of the most common things to look for to keep an eye on, whether you’re at home or running a business.
Water Draining Slowly
Water not draining like it used to? If your sink, bath, or shower’s feeling slow, that’s usually the big hint. In the kitchen, it’s leftovers building up. In the bathroom? Bath muck are the biggest offenders. If water’s not moving, it’s time to act.

Unpleasant Smells
That foul smell near the drain? That’s not just something in the air, it’s stuff left behind, starting to rot. Food, grease, even sewage can get caught up. If you’re picking up a stink, don’t ignore it. It means a problem is getting worse, and it’s better to sort it quickly.

Gurgling Sounds From Pipes
Drains gurgling? That’s a sign of trouble. Usually means water’s not flowing. If it sounds like a kettle, get it checked.

Water Backing Up
Water flooding back instead of draining? That’s one of the big red flags. A blocked drain is likely the cause. And trust me, if you’ve spotted it, it won’t clear up without help. Get on top of it early, and we’ll make sure it’s cleared quick.
Toilet Flushing Poorly
A toilet that doesn’t flush properly or takes longer than normal to refill may indicate a restriction within the soil pipe. These issues are often the result of foreign objects being flushed, common culprits include disposable cloths, feminine hygiene items, or large amounts of paper.
Overflowing Outdoor Drains
If you see water overflowing out of external drains during or after heavy rain, the issue may go deeper than simple surface runoff. A significant underground blockage could be stopping water from flowing, causing water to overflow. Left unaddressed, this overflow can lead to erosion, cracking, or structural issues. Prompt attention is advised to minimise damage.
Multiple Fixtures Affected at Once
Multiple drains acting up? That’s not a quick fix. If toilets, sinks, and your washer are all backing up, the blockage is probably in the central drain. Plunging won’t cut it. You need a proper look and jet gear to clear it properly.
Damp Patches or Mould
Sometimes it’s not obvious there’s a drain problem until you see damp patches on the floor or walls. You might get mould popping up where it usually isn’t, or smell something odd near the kitchen units or along the base of the wall. That’s often a sign something’s gone wrong out of sight.
