Regular – but quick! - exterior wipe downs of gutters and downpipes are recommended to maintain good condition. While you’re there, you can check for any leaking joints and if necessary, lift the gutter, clean gaskets, and re-clip the gutter (a silicone spray can help). Loose swan necks (off-set bends) or downpipe clips can also be re-secured. Be sure that you check any ‘grey water’ water butts fed by your gutters as well, as many have a leaf trap that could also need cleaning. Bear in mind - those that don’t, may also have a layer of silt and leaf debris at the bottom, which will need scooping out and flushing through with a hose.
