Outside Drain & Gully Unblocking
Outside Drain & Gully Unblocking
Water pooling around a gully or a drain smell in the garden usually means leaves, silt or fat have blocked the run between the house and the chamber.
Outside Drain & Gully Unblocking in North London, done properly the first time
We clear gullies, rodding eyes and inspection chambers using rods and high-pressure jetting, then flush the run to make sure it's genuinely clear rather than temporarily draining.
We also lift and check chamber covers for standing water, which tells us whether the blockage is on your private run or in the shared sewer — important to establish before any bigger work is proposed. We cover Barnet and the surrounding EN and N postcodes.

Your questions, answered
Is a blocked drain my responsibility or the water company's?
Runs within your boundary that serve only your property are yours; shared and public sewers are Thames Water's. We check the chambers and tell you which applies.
Can you attend the same day?
We keep same-day slots for drainage emergencies across Barnet and North London.
Do you use a camera?
Where a blockage keeps returning we can arrange a CCTV survey to find the underlying defect.
What causes outside drains to block?
Autumn leaves, kitchen fat, wipes, and root ingress into older clay pipes are the four we see most in North London.
