Moss on Your Driveway: Removal and Prevention
Driveways might seem too busy for moss, but it quietly takes hold along the edges, in joints between blocks and in any spot that stays damp. Over a few years it can spread into green carpets beside walls and lawns. Besides looking untidy, moss makes the surface slippery and its roots can disturb joints.
Where moss grows on a driveway
Moss favours the parts of a drive that tyres and feet rarely touch: the edges, the area beside a wall or hedge, under a parked car and in the gaps between blocks. Shade from the house, trees or a fence keeps those areas damp.
On tarmac, moss often grows in cracks and along edges where soil has washed onto the surface.
Different surfaces, different problems
On block paving, moss grows in the sand joints and can push blocks apart as it spreads. On concrete, it tends to settle in expansion joints and rough patches. On tarmac, it roots into cracks and porous areas. Gravel drives develop moss where the stones have thinned.
Our block paving cleaning page covers the particular care block drives need.
Slip risk
Wet moss is very slippery underfoot, particularly on a sloping drive. Paths from the drive to the front door are often shaded by the house and among the first areas to green over.
If anyone in the household is unsteady on their feet, those routes are worth prioritising.
How driveway moss is removed
Moss needs removing from joints and edges, not just washing over. The method depends on the surface, with care taken not to wash out jointing sand or damage soft surfaces. Our patio and driveway cleaning service looks at the surface first, then chooses the approach.
If there are sunken or loose areas, we will point them out; cleaning will not fix movement in the base.
Do it yourself or call someone in?
Small patches of moss on a level, sound surface can be scraped out of joints by hand with a suitable tool. Hiring a powerful pressure washer without experience can wash sand out of block paving joints and mark the surface.
If the area is large, the joints are fragile or you are unsure of the surface, ask for advice first.
Keeping moss away
Regular sweeping removes the soil and organic matter that moss needs. Clearing leaves before they rot, keeping gutters and drains clear so the drive isn't constantly wet, and trimming overhanging plants all help.
Our driveway cleaning guide has more practical upkeep advice.
Tarmac driveways
On tarmac, moss often grows along edges where soil has washed on, in cracks and in porous areas where the surface has worn. Cleaning removes the growth, but cracks remain and moss can return to them.
Cracked or crumbling tarmac is a surfacing issue rather than a cleaning one.
Concrete and imprinted concrete
Plain concrete drives develop moss in expansion joints and rough patches. Imprinted concrete often has a sealed surface; once that wears, the textured pattern can hold algae. The cleaning method needs to suit the surface.
Tell us what kind of concrete drive you have when enquiring.
Gravel and resin-bound drives
Gravel drives grow moss where stones have thinned and soil shows through. Resin-bound surfaces can develop algae on the top, especially in shade. Each needs different care, and gravel cannot be cleaned in the same way as a solid surface.
Our driveway cleaning guide covers several driveway types.
Edges beside lawns and borders
Where a driveway meets a lawn or flower bed, soil washes onto the paving with every downpour. That thin layer of soil is exactly what moss needs to establish. Edging, regular sweeping and keeping borders slightly lower than the drive all reduce it.
Moss at the edges usually returns first after cleaning, so it is worth watching these areas.

If your roof has moss too, roof work is best done first so debris does not land on the clean drive.

Frequently asked questions
Why is there moss on my driveway?
Shade, damp and soil in the joints let moss grow, mostly in areas tyres and feet rarely touch.
Will pressure washing remove driveway moss?
It can, but excessive pressure may wash out jointing sand or mark the surface. The method should suit the driveway.
How do I stop moss coming back on my drive?
Sweep regularly, clear leaves and soil, keep drainage working and let in light where you can.
Will cleaning fill the gaps in my block paving?
Cleaning removes moss and weeds from joints. Joints that have lost sand may need re-sanding afterwards.
Can moss damage block paving?
As it spreads, moss and the soil it traps can disturb jointing sand, which over time may let blocks move.
