  • What are the most common causes of blocked drains?

    Blocked drains are usually caused by a build-up of foreign materials such as hair, grease, soap scum, food scraps, or tree roots invading outdoor pipes. Over time, these obstructions restrict water flow and may lead to unpleasant smells or flooding. Identifying the cause early helps prevent damage and reduces the cost of repairs.

  • How do I know if I have a blocked drain?

    Signs include slow-draining sinks or showers, gurgling noises from pipes, foul odours, or water pooling around drains. Toilets may also overflow or take longer to flush. These symptoms usually mean there’s a blockage somewhere in your system. If left untreated, the problem can escalate and cause serious water damage.

  • Can I unblock a drain myself?

    Minor blockages can sometimes be cleared with a plunger or boiling water. However, chemical drain cleaners can damage pipes if misused, and DIY solutions often provide only temporary relief. Persistent or severe blockages usually require professional tools and expertise to fully clear the problem and prevent it from returning.

How We Fix Your Drains

We handle blocked drains using specialised equipment like CCTV drain cameras and high-pressure water jetting. These tools allow us to locate the problem precisely, remove stubborn build-ups, and prevent further damage to your system. Our goal is to provide lasting repairs that keep your drainage flowing freely, without the stress of recurring blockages.
