How Often Should You Clean Your Gutters?

Published by Tony Wright

Most homeowners in Northamptonshire don't think about their gutters until something goes wrong. A damp patch appears on the bedroom ceiling, or water starts running down the outside wall during heavy rain. By that point, the gutter has been blocked for weeks and the damage is already happening.

The short answer: twice a year for most properties. Once in late spring and once in late autumn. That schedule catches the two worst periods for debris buildup.

Why twice a year works

Winter drops leaves, twigs, and moss into your guttering. Spring growth adds seeds and blossom. By April or May, your gutters have had six months of accumulation sitting in them. A spring clear gets rid of all that before summer rain tests the system.

Then autumn arrives and the trees drop everything at once. October and November fill gutters faster than any other time of year. A clear in late November or early December means your gutters go into winter running freely, which is when they need to work hardest.

Properties that need more attention

If you have mature trees within 10 metres of your roofline, twice a year might not be enough. Oak, sycamore, and horse chestnut trees are the worst offenders. Their leaves are large, they drop in volume, and they clump together when wet. Three clears a year (spring, late summer, and late autumn) keeps properties like this under control.

Bungalows and single-storey extensions tend to collect more debris because the gutter sits closer to ground-level vegetation. If you have climbing plants near the roofline, expect to need more frequent clears.

Warning signs your gutters are blocked

You don't always need to get up and look. There are signs you can spot from the ground:

  • Water spilling over the gutter edge during rain
  • Green or damp staining on the wall below the gutter line
  • Plants or grass growing out of the guttering
  • Sagging sections where the weight of debris has pulled the gutter away from the fascia
  • Puddles forming at the base of downpipes that didn't used to be there

Any of those is worth investigating before the next rainy week.

What happens if you leave them

Blocked gutters cause water to back up behind the fascia board. That water has nowhere to go except into the wall cavity or down behind the external render. Over months, this leads to damp, mould, and in serious cases, structural damage to lintels and brickwork. Fascia boards themselves start to rot if they're timber, or discolour permanently if they're UPVC.

Replacing fascias costs thousands. A twice-yearly gutter clear costs a fraction of that.

Can you do it yourself?

You can, but it involves working at height. If you're comfortable on a ladder and confident you can reach the full run of guttering safely, a pair of gloves and a bucket will do the job. For most people, though, it's quicker, safer, and more thorough to have someone with the right equipment do it.

We use extended-reach tools that let us clear gutters from ground level on most properties. No ladders leaning against your walls, no risk of damaging the guttering by standing on it.

Pair it with a fascia clean

While the gutters are being cleared, it makes sense to clean the fascias and soffits at the same time. The green and black marks that build up on UPVC come from the same algae that grows in gutters. We can quote for both in one visit.
