Blocked Outside Drain & Gully in Nottingham

Common Causes of Blocked Outside Drains

Leaf and debris accumulation in the gully trap is the most frequent cause, particularly in Nottingham's tree-lined residential streets during autumn. A single gully trap can fill to capacity in a few days of leaf fall. Fat and grease from kitchen waste pipes are another common cause: they cool as they travel outside and settle in the gully trap or the drain below, forming a solid deposit that the trap cannot hold. Silt build-up in yard gullies — particularly in older properties where the gully hasn't been cleared in years — narrows the trap until even light rainfall overwhelms it. And in some cases the gully is clear but water pools around it because there is a blockage or structural problem in the drain further below.

DIY Cleaning vs When to Call

Removing the gully cover and scooping out leaves and silt is reasonable first-line maintenance that any householder can do — wear gloves and use a trowel or scoop. If the trap looks clean but water is still not draining away, the restriction is in the drain run below the gully, and the job needs a professional. If there is a sewage smell from the gully, do not put your hand in without appropriate protection — call us instead. A sewage-smelling outside gully suggests the drain below is connected to foul drainage and the smell is coming up from a blockage or structural problem further along.

How We Clear It

We lift and clean the gully trap, removing all debris, and rod or jet the drain run below as required. Where there is any doubt about what is causing the problem, or where clearing the gully doesn't resolve the pooling water, we use CCTV to confirm the run is clear and check for structural issues further along. We test the drainage before leaving and confirm the gully is draining freely.

Standing Water — When It Might Mean More

If standing water persists around an outside drain after the gully trap has been cleared and the drain run has been jetted, the cause is likely structural: a damaged drain below, a failed soakaway, or a ground-level drainage problem that is backing up to the gully. We investigate the specific cause before advising on the next step — rather than suggesting a soakaway replacement as a first guess.
