Frequently Asked Questions
Get answers to common questions about our drainage services
We aim to reach most properties in Watford within an hour for emergencies. On arrival, most outside blockages can be cleared promptly using high-pressure water jetting.
If the drain is shared with a neighbour or is a public sewer, responsibility often falls to the local water company. For private drains within your property boundary, you’re usually responsible.
Keep children and pets away from the affected area. Avoid flushing toilets or using sinks linked to the blockage until the engineer arrives.
Drain lining can repair cracks and minor faults without excavation, saving time and disruption. Badly collapsed pipes may still need to be dug up and replaced.
We work throughout Hertfordshire, visiting homes and businesses in Abbots Langley, Aldenham, Borehamwood, Bushey, Garston, Holywell, Kings Langley and Letchmore Heath.
Drain jetting flushes blockages clear using high-pressure water. We also check the system for further issues and advise if any repairs are needed.
