Common warning signs include slow-draining sinks, baths or showers, gurgling noises from pipes, unpleasant odours from drains, water backing up in toilets or sinks, and damp patches or pooling water in your garden near drain covers. If you notice any of these symptoms, contact us immediately – early intervention prevents costly damage.
The most frequent causes of blocked drains in London include fat, oil and grease build-up from kitchens, hair and soap residue in bathroom drains, tree root intrusion through cracked pipes, foreign objects flushed down toilets, and collapsed or damaged pipes due to age or ground movement. Our CCTV surveys identify the exact cause so we can apply the right solution first time.
When you call us, a fully equipped engineer arrives within 60 to 90 minutes. We begin with a visual inspection and, if needed, a CCTV drain survey to pinpoint the blockage location. We then clear the blockage using high-pressure water jetting, which is effective against fat, grease, scale and debris. Once cleared, we run a final camera check to confirm the drain is flowing freely and identify any underlying issues that could cause future problems.
