CCTV Drain Surveys in Highgate
If a blockage doesn’t clear properly, a CCTV drain survey helps us see exactly what’s going on inside the pipes. Instead of digging up your garden or trying things blindly, we thread a lens through the drain and have a nosey. It shows us if there are cracks, damage, tree roots, or a big old build-up of mess. That way, we know where the problem sits and where to fix it.

Signs You Have a Blocked Drain
Sure, some drainage problems make themselves known fast. But most start small. Spot the early signs and you’ll stay ahead of the problem. Check out this quick checklist if you think your drains might be getting blocked.
Water Draining Slowly
Water not going down right? If your sink, bath, or shower’s getting sluggish, that’s usually the early sign. In the kitchen, it’s food and fat. In the bathroom? The usual build-up are the usual suspects. If water’s not moving, it’s time to act.

Unpleasant Smells
Nasty whiff from a drain? That’s a warning sign. Grease, sewage, or worse is probably stuck. Smell it near the sink? Don’t wait. A blockage is forming.

Gurgling Sounds From Pipes
Odd gurgling coming from your drains, particularly air-like noises, are often a sign that air is trapped in the plumbing system. This typically occurs when water is unable to flow smoothly, causing vacuum pressure. If your pipes begin making noises reminiscent of a kettle, it’s advisable to have them professionally inspected.

Water Backing Up
One of the easiest to spot indicators of a blocked drain is water reversing direction. If you notice any sign of reverse flow, it’s important to act quickly to prevent it from becoming more serious.
Toilet Flushing Poorly
Toilet not clearing or taking too long? Might be a blockage in the line. Wipes, tampons, or too much paper usually to blame. Call it in.
Overflowing Outdoor Drains
If you see water emerging from external drains during or after heavy rain, 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 untreated, this overflow can damage gardens, driveways, and even the structural foundations of your property. Prompt intervention is recommended to prevent further complications.
Multiple Fixtures Affected at Once
When several plumbing fixtures in your property are slow to drain all together, it’s often a sign of a blockage within the main drain line. Such blockages can impact the function of toilets, sinks, bathtubs, and even washing machines. In these situations, quick fixes like plunging are unlikely to be sufficient. A thorough investigation using video diagnostics, followed by professional jetting, is typically needed to get rid of the obstruction.
Damp Patches or Mould
Drain problem? It’s not always easy to spot. Damp on the floor or wall? Mould in odd spots? Stale odour under the sink? That could be a hidden leak. Time to check it out.
