DUBLIN, Ireland, 2 November 2026 - After a run of damp weeks, patio slabs in shaded corners turn green. Algae, moss and lichen thrive on stone that stays wet, and a film of algae makes paving slippery underfoot. Before booking Patio Cleaning Services in Dublin, homeowners can run five quick checks themselves.
Quick checks before you clean
Walk the wettest, shadiest slab slowly. If it feels slick, treat that area first.
Look along north-facing and shaded edges, where algae and moss start.
Note where water pools after rain, because poor drainage keeps slabs damp.
Check dark patches near a barbecue or a parked car. They point to oil, not algae.
Look at the joints between slabs for moss and weed growth.
Spot what is growing on the surface
Algae is a green or dark film that feels slimy when wet. Moss forms raised cushions, often in the joints. Black speckles are lichen or mould. Oil stains are dark and flat, and a hose will not shift them.
M.R Garden & Tree Service, based in Lucan, Co. Dublin, lists algae, moss, lichen, mould and oil stains among the problems its team removes from patios.
Match the method to the material
Common patio surfaces are natural stone, concrete and block paving. Pressure washing suits concrete and block paving. Soft washing is gentler and suits delicate stone and older patios. Anyone comparing Patio Cleaning Services in Dublin should ask which method will be used on their surface.
Ask for solutions that are safe for plants, pets and people, because most patios sit beside lawns or flower beds.
What a professional clean involves
A thorough job follows a set order:
A site inspection and an assessment of the material
A pre-treatment to loosen the build-up
Cleaning with the method that suits the surface
Individual treatment for stains
A final rinse and clean-up
Timing
The company advises cleaning a patio once a year, and more often in high-traffic areas. Autumn, before the first frost, is the point when green growth turns slippery.
Cost
The price of a patio clean depends on five factors:
The size of the patio
The material
How dirty the surface is
Whether the property is a home or a business
How easy the area is to reach and drain
