A blocked downpipe can cause gutter overflow or water to spill from joints when rain cannot reach the receiving drain. We check the visible pipe and what it discharges into rather than assume the obstruction is at the top.
Blocked Downpipe

Downpipe bends and outlets
Overflow can be caused by debris in the pipe or by a restriction where the downpipe reaches the receiving drainage.
Safe working access
The building height and surrounding ground determine the suitable access method.
Bends and the drainage at ground level
Leaves and debris can lodge at an offset bend or where the downpipe enters a gully. If the downpipe connects directly to underground surface-water drainage, a restriction below ground can make the visible pipe back up.

Safe access to the affected section
Building height, ground conditions and nearby services determine how the downpipe can be reached safely.
Blockage or damaged rainwater pipework
A split joint, loose connection or damaged bend can leak even when the pipe is clear. We distinguish those defects from the debris removed and check the receiving drainage where access allows.
Blocked Downpipe: common questions
Why does water leak from a downpipe joint?
A blocked downpipe or receiving drain can back water up, but a loose or damaged joint can also leak.
Is a blocked downpipe the same as a blocked sewer?
No. A downpipe normally carries roof water, and its receiving drainage should be identified rather than assumed to be a foul sewer.
Can a blocked gully make the downpipe back up?
Yes. A restricted receiving gully or drain can prevent water leaving the downpipe.
Why can building height affect downpipe clearance?
The access method has to suit the building height, ground conditions and surrounding area.
Does downpipe clearance include repairing damaged joints?
Repair work is separate unless it is included in the agreed job.
