Autumn is the season that decides whether your gutters get through winter cleanly or spend it overflowing down your walls. This checklist covers everything worth doing between now and the end of November: a ground-level inspection, a downpipe check, a look at the fascias, and — the most important item — booking a professional clean for after the leaves have finished falling.

Work through it in order. Because every item can be done from the ground, none of it requires a ladder, and the whole inspection takes under half an hour.

1. Walk the Property and Check the Gutter Line

Start with a slow lap of the house from the pavement or garden. The gutters should form a neat, straight line with a slight fall towards each downpipe. Look for sections that sag, bow downward, or pull away from the fascia — these are signs that debris and standing water are already weighing the system down.

Additionally, look up at the gutter edge itself. Weeds, grass, or moss visible from the ground mean debris has been sitting long enough to become a growing medium, and the gutters are overdue for a clean.

2. Watch the Gutters During the Next Rainfall

Nothing diagnoses a gutter like rain. During the next decent shower, spend two minutes watching the roofline. Water sheeting over the gutter edge, dripping at joints, or spilling behind the gutter onto the fascia all point to blockages or failed seals. However, water flowing quietly to the downpipes means the system is still coping — for now.

Mark any problem spots mentally, because they’re the first places a professional should check.

3. Check the Downpipes and Gullies

Downpipes are where autumn blockages most often take hold. During or just after rain, check that water is actually emerging at the bottom of each downpipe. A gutter overflowing above a silent downpipe usually means a plug of leaves has capped the outlet.

At ground level, clear leaves away from the gully or drain grate that each downpipe feeds into. Since a blocked gully backs water up the pipe, this two-minute job prevents a surprising number of problems.

4. Look for Overflow Stains on the Walls

Examine the brickwork or render directly below the gutter line. Dark streaks, green algae staining, or damp patches indicate water has been overflowing for some time — a sign the gutters were already struggling before this autumn’s leaves arrived. In that case, don’t wait for the end of leaf fall; a clean now, plus a follow-up if needed, beats another two months of soaking. Our guide to the warning signs your gutters need cleaning covers what each type of staining means.

5. Inspect the Fascias and Soffits

While you’re looking up, check the boards behind and beneath the gutters. Peeling paint, dark staining, or visible sagging on the fascia boards suggests overflowing water has been getting behind the gutter. Because rotten fascias can’t hold gutter brackets securely, catching this early keeps the fix small.

6. Note Your Tree Cover

Count the mature trees within about ten metres of your roofline. Streets across Uxbridge, Harrow, and Hillingdon are lined with planes, oaks, and limes, and a single mature tree can fill a gutter run in one autumn. Heavy tree cover means two things: your clean should wait until the leaves have mostly finished falling, and a twice-yearly schedule is worth considering. For the full reasoning, see how often gutters should be cleaned.

7. Time the Clean for After Leaf Fall

The most common autumn mistake is cleaning too early. A clean in early October gets buried under the second half of the season’s leaf drop within weeks. Around London, most leaves are down by mid-November, which makes late November the ideal slot for the main clean. Our post on the best time to clean gutters in the UK explains the seasonal logic in detail.

8. Book Early — November Fills Up Fast

Everyone’s leaves fall at the same time, so late autumn is the busiest period of the year for gutter companies. Therefore, book your slot in advance rather than waiting for the first overflow. A professional gutter cleaning visit covers what the checklist above can only observe: vacuum removal of all debris, a downpipe flush with a flow test, and before-and-after photos so you can see the result without leaving the ground. If the inspection turns up loose brackets or failing joints, you’ll get a written recommendation rather than a surprise next spring.

Frequently Asked Questions

When in autumn should I have my gutters cleaned?

After the majority of leaves have fallen — typically mid-to-late November in the London area. Cleaning earlier in autumn risks the remaining leaf drop refilling the gutters within weeks.

Can I do autumn gutter maintenance myself?

The checks in this list are all safe, ground-level tasks: watching for overflow, checking downpipes, and clearing gullies. The clean itself is best left to professionals with vacuum equipment and insurance for working at height, since ladder work is where DIY gutter maintenance goes wrong.

What happens if I skip the autumn clean?

Leaf debris compacts into a dam, and the gutters then overflow through winter — the UK’s wettest season. Repeated soaking of the wall below leads to staining, damp, and rotting fascia boards, all of which cost far more to fix than a routine clean.

Do downpipes need clearing as well as gutters?

Yes. Downpipes are where autumn blockages most often form, and a capped outlet backs up the entire gutter run. A proper professional clean includes flushing the downpipes and testing water flow, not just clearing the visible channel.
