How often, by property
| Situation | How often |
|---|---|
| Open site, no trees nearby | Once a year, late autumn |
| Trees within throwing distance | Twice a year — autumn and spring |
| Conifers or evergreens overhanging | Twice a year, minimum |
| North-facing run that grows moss | Twice a year |
| Three storeys, hard access | Once a year, but do not skip it |
Why late autumn is the one that counts
Deciduous trees around here finish dropping in early to mid November. Clear before that and you are clearing part of the load, then paying again in December when the rest comes down.
The point of the autumn clear is to get the system empty before the winter rain, because that is when a blocked gutter does its damage. A gutter that overflows in July dries out. One that overflows from November to March keeps a wall wet for five months.
The signs it needs doing now
- Water spilling over the front edge in heavy rain
- Green or dark staining running down the wall beneath a joint
- Plants — actual plants — growing out of the run
- A downpipe that stays silent while it is pouring
- Birds nesting at the gutter line
- A damp patch on an inside wall that nobody can explain
That last one is worth taking seriously. Gutters are the most common cause of unexplained internal damp on a house, and they are the cheapest to rule out.
What happens if it is left
The failure is not what people expect. A blocked gutter does not simply overflow down the front — it backs up and spills behind the gutter, against the fascia board and the wall head. That is out of sight.
So the sequence is: blockage, then a wet fascia board, then rot in the board, then the brackets lose their fixing and the run starts to sag, then it never drains properly again whatever you do to it. At that point a £120 annual clear has become a £1,200 fascia-and-guttering replacement.
What about gutter guards?
They help with leaves and they do not help with the fine stuff. Silt, moss spores, roof grit and seed still get through most mesh systems and build up underneath, where they are harder to reach than they would have been in an open gutter. They lengthen the interval; they do not remove it.

Questions
Frequently asked questions
What is the best month to get your gutters cleaned?
November, once the leaves are genuinely down. Clearing in early October while the trees are still shedding means paying for it twice. If you only do it once a year, do it in late autumn — that is the clear that carries the system through the wet months.
How many times a year should gutters be cleaned?
Once for most houses, twice where there are overhanging trees or a north-facing run that grows moss. Conifers and evergreens shed year-round, so those properties genuinely need two.
How do you know when your gutters need to be cleaned?
Water running over the front edge in heavy rain, green staining down the wall under a joint, plants growing out of the run, or a downpipe that stays silent while it is pouring. An unexplained damp patch on an inside wall is very often a gutter.
What happens if you do not clean your gutters?
The run overflows behind the fascia rather than in front of it, which soaks the wall head and rots the fascia board the gutter is fixed to. Once the board goes, the brackets have nothing to hold and it becomes a replacement job instead of a clean.
