Professional decking cleaning

A proper process for a lasting improvement.

Decking often becomes green and slippery because moisture sits within the board texture and shaded joints. Blasting timber at excessive pressure can feather the grain, leave stripes and shorten the life of the surface.

A controlled clean combines lower pressure with suitable treatment to remove algae and ingrained dirt while respecting the board material. Both wooden and composite decking can be assessed.

For suitable timber, optional oiling, staining or painting can be discussed once the boards are clean and fully dry.

Decking Cleaning FAQs

Questions customers commonly ask.

Need advice about a specific surface? Send photographs and the property postcode for a more useful answer.

Can pressure washing damage decking?
Yes, excessive pressure can mark timber and raise the grain. The pressure, nozzle distance and cleaning direction must be controlled.
Do you clean composite decking?
Yes. Composite boards can be cleaned using a method appropriate to their manufacturer, texture and condition.
Can you oil or stain the decking afterwards?
Finishing options can be quoted for suitable wooden decking after cleaning and adequate drying.
Will cleaning make decking less slippery?
Removing algae and organic build-up normally improves grip, although the board design, shade and weather will continue to affect the surface.
