Gutters are the sort of thing you only think about when water's pouring over the edge in the middle of a storm. By then the damage is already starting.
What goes wrong
Leaves, bark, roof grit and seedlings build up. Seedlings are a surprise to many people. Seeds blow in, settle in the muck, and start growing in your gutter. A blocked gutter overflows, and that water ends up behind fascia boards, down walls, or soaking around the foundations. It's also a place for mosquitoes to breed.
The job
Gutters are cleared by hand, flushed with water to check that they're running, and the downpipes are checked and unblocked. While we're up there, we have a look at the general condition: loose brackets, rust spots, sagging sections, joins that look like they might leak. We'll tell you what we see, and quote separately for any fix.
When to do it
Ideally just before the wet season starts, so the gutters are clear when you need them. A second clean afterwards makes sense if you have trees overhanging the roof. Properties under big trees may need a clean more often than those with open skies.
It pairs well with pressure cleaning of the roof and walls, and with a small repair if a bracket or join needs attention.
Working at height
Single-storey roofs are the usual. If your place is tall, steep, or has awkward access, say so when you ask for a quote. Some roofs aren't safe to do from a ladder, and we won't take a risk we shouldn't.
