Cleaning your gutters: when and how to do it effectively
Gutters play an essential role in protecting your home: they collect the rainwater from the roof and carry it to the downpipes, away from the foundations. If they get blocked, the water overflows, seeps under the tiles, runs down the walls and can even damage the foundations. Regular cleaning, twice a year, is generally enough to avoid these nuisances.
When to clean your gutters?
The most common rule is to clean the gutters at least twice a year: in autumn after the leaves fall, and in spring after periods of wind and pollen. If you live near deciduous trees, an extra pass at the end of the rainy season may be necessary. A simple indicator: as soon as the water overflows the edge of the gutter in rain, or when plants grow in the gutter, it is time to act.
Adapting the frequency to your environment
The ideal frequency depends above all on your environment. A house surrounded by tall trees, especially broadleafs that lose their leaves in autumn, will require a more frequent pass than an isolated house in a neighbourhood with no vegetation. In windy or high-rainfall regions, leaves also accumulate faster. If you regularly notice debris in the gutter before the planned date, do not wait: a few minutes of prevention are worth more than an infiltration. A gutter guard remains the most effective solution for spacing out the interventions.
The necessary tools
- Thick gardening gloves: decomposed leaves can contain sharp debris and insects.
- A small gutter scoop or a trowel, and a bucket hung on the edge of the gutter to collect the debris.
- A garden hose to rinse and check the flow.
- A stable ladder with a stabiliser, or scaffolding if the house is tall.
- For hard-to-reach facades: a telescopic broom or a ground-level gutter cleaning kit, generally sold between 20 and 60 €.
- Optional: a mesh gutter guard (a few euros per metre) to limit the entry of leaves.
The cleaning steps
- Set the ladder on stable, flat ground, never on a slope or soft ground, and ideally work with someone with you.
- Remove the large debris by hand or with the scoop, starting at the bottom of the gutter's fall and working up.
- Unblock the downpipes: if the water stagnates, unscrew the bottom elbow of the downpipe to remove the leaf plug.
- Rinse the gutter with the garden hose starting from the highest point: the water must flow freely towards the downpipe.
- Check the fixings: the brackets and joints must not be loose or rusted.
- Check the fall: as a general rule, the gutter must have a slight slope (a few millimetres per metre) towards the downpipe so the water flows without stagnating.
The mistakes to avoid
- Standing on the edge of the gutter or leaning on it: it can give way under your weight and cause a serious fall.
- Cleaning in the rain or when the gutter is frozen: the surfaces become slippery and dangerous.
- Pushing the debris into the downpipe hoping it will pass: it forms a plug that is often impossible to remove afterwards.
- Forgetting the valleys and corners, which are the areas where debris accumulates fastest.
- Filling the gutter with water from the hose without checking that the water comes out properly through the downpipe at the bottom of the wall.
Very high or hard-to-reach gutters?
For a house of one storey or more, or if you are not comfortable on a ladder, several solutions exist: telescopic gutter brooms let you work from the ground for a few dozen euros, and cleaning companies offer this service with scaffolding or a cherry picker. Do not hesitate to ask for a quote: it is often safer and quicker than taking an unnecessary risk.
The particular case of winter
In winter, a gutter full of damp leaves becomes the starting point of ice plugs: rain or melting snow water accumulates, freezes and can make the water overflow under the tiles, or weigh heavily on the brackets. If you live in a cold region, do a final clean before the first frosts, then check the flow after each big thaw. Never try to break the ice inside the gutter with a metal tool: you risk piercing or deforming the profile, and the ice can be harder than expected. Wait for the temperature to rise, or simply clear the top of the downpipes.
Regular, methodical cleaning of your gutters is one of the most cost-effective maintenance actions in the house: two passes a year, simple tools and an hour of work are enough to preserve your walls, foundations and roof. Think of it before the big rains, and your gutter will do its job without overflowing for years.
