Gullies & rainwater drainage in Macclesfield
In short
Gullies take waste water and rainwater into the drain, and they block with leaves, silt and moss from the roof. Clearing them is a small job that prevents a large one — an overflowing gully puts water against the wall of the house, which is where damp problems start.
Also called: blocked gully · downpipe blocked · surface water drain · rainwater not draining
Signs you need this
- Water standing over a gully after rain
- A downpipe overflowing at a joint
- Moss, leaves and silt visible in the gully
- Damp on an internal wall behind a downpipe
- Water surfacing in the yard during heavy rain
A gully is the small grated chamber at the base of a downpipe or beneath a waste outlet, with a trap below it to keep smells out. It collects everything the roof and the yard deliver, and it is the most neglected component in domestic drainage: nobody thinks about it until water is standing over it.
Clearing is mostly manual — lift the grid, remove the debris from the trap, flush it through — and it is worth doing seasonally on a property with trees nearby. A missing or broken grid should be replaced rather than left, because without it the gully takes everything, including the gravel and leaves that will block the drain beyond it.
Downpipes block above the gully too, particularly at the shoe and at any offset. A downpipe overflowing at a joint in heavy rain is soaking the wall behind it, and on an older solid wall that is a direct route to internal damp. It is a five-minute job to clear and an expensive one to ignore.
Surface water deserves particular attention in this town. Cheshire East's Preliminary Flood Risk Assessment identifies Macclesfield as the borough's only designated Flood Risk Area, with 47 internal flooding incidents recorded since 2011 — the most of any town in the borough — and points to an ageing network of unmapped, culverted watercourses beneath the town as part of the cause. In that context, keeping your own surface water drainage clear and flowing is not housekeeping; it is the part of the system you can actually control.
Where a property regularly floods around the gullies in heavy rain, the questions are whether the surface water drain is blocked, whether it is undersized for the area it drains, and whether it is connected to a combined sewer that surcharges in storms. A camera survey answers the first two.

What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your plumber has to honour it. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
How often should gullies be cleared?
Twice a year is sensible for a property with trees nearby — after autumn leaf fall and again in spring. A gully that stays clear is a drain that does not block.
Water pools around my drain in heavy rain — is that a blockage?
Often, but not always. It can also mean the surface water drain is undersized or that a combined sewer is surcharging in storms. Clearing it is the first step; a survey answers the rest.
