Unpleasant smell from an artificial lawn

Artificial Grass That Smells: Causes and Cures

Artificial grass has no smell of its own. Odour comes from organic residue trapped in the infill or sitting on an impermeable layer that will not let it flush away.

Almost every case we are called to traces back to how the lawn was built.

Where the smell is held

Sand infill absorbs residue. If the lawn was laid on a weed membrane over compacted clay with no free-draining stone below, liquid cannot escape and sits in the sand.

Non-permeable or hole-punched backings with too few perforations have the same effect.

Treating an existing lawn

Rinsing thoroughly and applying an enzyme-based artificial grass cleaner breaks down the residue rather than masking it. Bleach and strong disinfectants damage the yarn and only cover the smell temporarily.

Where the sand is saturated, removing and replacing the infill makes a dramatic difference.

Getting the specification right

A pet installation should have a fully permeable backing, a free-draining stone sub-base, and an antimicrobial or zeolite infill that captures ammonia between rinses.

Done that way, routine rinsing is all that is needed.

Frequently asked questions

Can a smelly lawn be saved without replacing it?

Often yes — infill replacement and enzyme treatment resolve most cases if the base drains.

Is bleach safe on artificial grass?

No. It can damage fibres and only masks the source.

Do you retro-fit better drainage?

We can lift the grass, correct the base and relay it where the turf itself is sound.

Odour problems with a previous install?

We diagnose the base and put pet installations right.
