CCTV Drain Surveys in St James
When a blockage proves persistent or difficult to diagnose, a CCTV drain survey provides a detailed inspection of your drainage system. Rather than relying on excavation or assumptions, we insert high-definition cameras that navigate through the pipes, delivering live footage to our engineers. This process allows us to detect issues such as fractures, structural failure, tree intrusion, or severe waste build-up. With this information, we can identify the exact cause and location of the problem and determine the most effective solution.

Signs You Have a Blocked Drain
Sometimes drain problems are easy to spot. Other times, you’ve got to catch the little signs early to avoid a whole load of hassle. Here are some of the main things to look out for if you think something’s not right with your drains at the house or business.
Water Draining Slowly
Slow drainage in sinks, bathtubs, or showers is often the earliest indication of a forming blockage within your plumbing system. In kitchens, the cause is frequently fat and food waste, while in bathrooms, it’s typically a build-up of hair, soap residue, and mineral scale. If water is sitting, it’s a clear sign the system should be investigated.

Unpleasant Smells
Bad smell from a drain? That’s a warning sign. Food, fat, or worse is probably trapped. Smell it near the sink? Don’t wait. A clog is forming.

Gurgling Sounds From Pipes
Drains noisy? That’s a warning. Usually means water’s not flowing. If it sounds like a boiler, sort it.

Water Backing Up
One of the most apparent indicators of a blocked drain is water rising back up. If you observe any sign of water backing up, it’s important to get it looked at to prevent it from developing further.
Toilet Flushing Poorly
If your toilet isn’t working right or struggles to reset, it could mean there’s a blockage somewhere in the drainage system. These blockages are often caused by non-flushables, like wipes, pads and tampons, or too much paper. It’s best to call in help before it gets worse.
Overflowing Outdoor Drains
Water spilling from outside drains after rain? That’s a red flag. Might be a serious backup. If water can’t get through, it backs up. That overflow? It can undermine your foundation. Don’t wait, deal with it.
Multiple Fixtures Affected at Once
Multiple drains backing up? That’s not a minor fault. If toilets, sinks, and your washer are all backing up, the blockage is probably further down. Plunging won’t fix it. You need a proper look and high-pressure water jetting to get it done right.
Damp Patches or Mould
A drainage issue isn’t always obvious, but some signs can help you catch it early. If you’ve noticed wet spots on the floor or wall, unexpected fungal growth, or a mouldy odour near cupboards or along the baseboard, it could suggest a hidden leak or blockage.
