# How long does artificial grass last?

> A good-quality artificial lawn that's properly installed and looked after should last many years. As a reference point, the UK's Football Foundation expects a well-maintained 3G football pitch, under far heavier use, to last 10 to 12 years. How long yours lasts depends mainly on the grass quality, the groundwork, how much wear and sun it gets, and basic care.

## No single figure

There's no one number that holds for every lawn. A good-quality artificial lawn that's properly installed and looked after will last many years, but how many depends on the grass and the groundwork, how much use it gets and how much sun it sits in.

As a reference point, the Football Foundation in the UK expects a well-maintained 3G football pitch to last [between 10 and 12 years](https://footballfoundation.org.uk/pitch-replacement-fund-advice) before the surface needs replacing. A pitch takes far heavier wear than a family garden, but a garden lawn sits out in the same sun and weather all year, so treat that as a benchmark rather than a promise.

## What decides how long it lasts

### The grass itself

Better grass has UV-stabilised fibres that hold out against fading and going brittle. The pile is denser, so it springs back after it's walked on, and the backing is strong enough to hold the fibres firmly. Cheaper grass can look grand on day one and then flatten, fade or shed sooner.

### The installation

This counts for as much as the grass. A lawn on a properly compacted stone sub-base stays level and drains well. One laid on soil or old turf will sink, ripple and hold water, and that movement puts strain on the joins and edges. Badly made joins can open up, and loose edges get caught and lifted. We explain how we do it on the [how we install](/artificial-grass-installation/) page.

### How it's used

A quiet front lawn wears far more slowly than a back garden with children, a trampoline and a dog or two. Wear that's concentrated in one place shows first: the path to the shed, say, or the line a dog runs along the fence.

### Sun and weather

UV light is what slowly fades and weakens the fibres. Ireland's cloudy climate is easier on artificial grass than hotter, sunnier countries, but a south-facing lawn still gets plenty of exposure over the years. Rain itself does no harm, provided the base drains.

## What shortens its life

Most early problems come down to a handful of causes:

- **Poor groundwork**, leading to sinking, puddles and stretched joins
- **Heat damage** from barbecues, fire pits, chimineas, fireworks and dropped cigarettes, all of which can melt the fibres
- **Reflected sunlight** from some windows or glass, which can now and then scorch a strip of grass
- **Debris left to rot**, which brings on moss and weeds and can stain the fibres
- **Heavy items left in one place** for long periods, crushing the pile
- **Harsh chemicals** such as solvents, bleach or fuel spills
- **Metal rakes and wire brushes**, which pull and damage the fibres

## Care that helps it last

Looking after artificial grass takes far less time than mowing, but a bit of regular care does lengthen its life:

1. Clear leaves and debris before they break down on the surface.
2. Brush against the pile every few weeks to keep the fibres upright.
3. Rinse dog areas regularly so residue doesn't build up.
4. Top up kiln-dried sand in busy areas, where it's been used.
5. Move garden furniture and play equipment around now and then.
6. Keep anything hot on a patio, not on the grass.

Our guide on [how to clean artificial grass](/guides/how-to-clean-artificial-grass/) covers this step by step.

## Signs it's coming to the end

Every artificial lawn gets tired in the end. The signs are:

- fibres that feel brittle or break off when brushed
- patches that stay flat no matter how much you brush them
- noticeable fading, especially in the sunniest parts
- a backing that's starting to break down or tear

## Repair or replace?

Localised damage, like a burn mark or a worn patch, can usually be cut out and a new piece joined in. The new grass may look a little fresher than grass that has weathered for a few years, but a repair is often far better value than replacing the whole lawn.

If the problem is the base, with sinking or puddling across the lawn, the grass may have to be lifted so the groundwork can be put right. If the grass is still in decent condition, it can sometimes be relaid instead of replaced.

| Problem | Usual fix |
|---|---|
| Burn mark or small worn patch | Cut it out and join in new grass |
| Flattened areas | Regular brushing, moving furniture, topping up sand |
| Open join or lifting edge | Re-join it or re-fix the edge |
| Sinking or puddles across the lawn | Lift the grass, rebuild the base, then relay or replace |
| Brittle, faded fibres throughout | Replace the grass |

## Getting the most out of it

The two biggest things in your control are picking decent grass and having it laid on a proper base. After that, a few minutes of care every so often does the rest. We've been fitting artificial grass for more than 20 years, and we'll always give you a straight answer about which grass suits the way you use your garden.

## Questions
### Does artificial grass fade in the sun?

Good-quality grass has UV-stabilised fibres to slow fading, but all artificial grass loses some colour over the years, more so in full sun. Ireland's cloudy climate is easier on it than hotter, sunnier countries.

### Can damaged artificial grass be repaired?

Often, yes. A burn mark or worn patch can usually be cut out and a new piece joined in, although the new grass may look a little fresher than grass that has weathered for a few years.

### What shortens the life of artificial grass?

Poor groundwork, heat damage from barbecues or reflected sunlight, heavy wear in one spot, and debris left to rot on the surface. A good installation and a bit of care avoid most of these.

### How do I know when artificial grass needs replacing?

The fibres feel brittle or break off, some patches stay flat however much you brush them, the colour has faded noticeably, and the backing is starting to break down.
