Blocked downpipes are one of the most common causes of overflowing gutters—and one of the most overlooked. If water’s backing up in your guttering system, a blocked downpipe is often to blame.
Here’s what you need to know to spot the issue early, prevent damage, and deal with it properly.
What Causes Downpipes to Block?
Leaves and moss: Especially in autumn, leaves and moss easily get washed into the pipe.
Roof debris: Broken tiles, dirt, and bird nesting materials can fall into the gutter and cause clogs.
Poor maintenance: Downpipes that haven’t been cleared in years are almost guaranteed to have blockages.
Signs Your Downpipe Is Blocked
Water pouring over the top of the gutter during rain
Gurgling sounds in the downpipe
Water stains on walls near the downpipe
Little or no water exiting at the base
If you live in areas like Haslemere or Alton where heavy rainfall is common, these signs shouldn't be ignored.
Why Blocked Downpipes Are a Big Problem
Left unchecked, a blocked downpipe can:
Cause gutters to overflow
Lead to damp inside your home
Erode soil near your foundation
Cause damage to brickwork and render
How to Fix a Blocked Downpipe
DIY Option
You can try to clear the blockage using a drain rod or high-pressure hose, but it’s often messy and not always effective — especially if the blockage is deep.
Professional Help
A gutter cleaning expert will use high-reach equipment and CCTV inspections to safely and effectively clear your downpipes. They’ll also check for cracks, splits, or joint problems while they’re up there.
Prevention Is Cheaper Than Repairs
Regular maintenance — at least twice a year — is the best way to avoid blocked downpipes. It’s particularly important in wooded areas around Farnham and Petersfield where falling debris is more frequent.
