Decking Cleaning

Bring your garden decking back to life with expert cleaning from Sanderson Cleaning Services.

Over time, timber and composite decks become slippery and discoloured from algae, mould, dirt, and general weathering. Our specialist decking cleaning service restores the natural look and makes your decking safe underfoot again.



Our Decking Cleaning Process

Inspection & Assessment
We begin by evaluating the condition and material of your decking—be it softwood, hardwood, or composite. This helps us choose the right cleaning method to avoid damage while ensuring a deep, thorough clean.

Low-Pressure Washing

Unlike harsh jet washing that can splinter wood, we use controlled soft washing or low-pressure techniques to gently but effectively remove grime, algae and stains without damaging the surface.

Anti-Algae & Moss Treatments

We apply specialist biocides to kill off moss, lichen and algae spores at the root, helping to prevent regrowth and reduce slipperiness for the long term.

Optional Aftercare Advice

Once cleaned, we can advise on re-oiling or protective treatments to keep your decking looking fantastic and lasting longer.
