Why Decking Cleaning Is Important
Regular decking cleaning helps improve appearance, reduce slippery build-up and maintain the condition of timber or composite surfaces.
Outdoor decking is constantly exposed to moisture, leaves and weather changes, which can quickly lead to surface discolouration and algae growth if not cleaned regularly.

Where required, an appropriate cleaning treatment can be used to help loosen algae, moss and organic growth.

The decking is cleaned using pressure and methods appropriate to the material and its condition.
