Best Time of Year to Clean Patios and Decking

March 2026 • 5 min read

Patios and decking take a battering from UK weather. Knowing the best time of year to have them professionally cleaned in Frome, Somerset, Bath and nearby areas can mean better results and a surface that stays cleaner for longer.

When to book: spring and early summer lead the way

Spring (March–May) is ideal for most patios and decking. Winter has left moss, algae and grime at a peak; days are longer and (usually) drier, so surfaces dry well after cleaning. You get a fresh start before the main outdoor season. Early summer (June) is also excellent – warm, dry weather helps treatments work and speeds drying.

Autumn: a solid second choice

Cleaning in autumn (September–October) removes a summer’s worth of dirt and growth before winter. Good for shaded areas that green up quickly. Avoid very wet or cold spells so the surface can dry properly.

What to avoid

• Frost and freezing – Risk of ice and damage; avoid winter pressure washing.
• Prolonged rain – Hard to get a lasting clean; book when a drier spell is likely.
• Strong midday sun on decking – Can dry wood too fast; morning or late afternoon is better for timber.

Why timing matters in Somerset and the South West

Shaded gardens in Bath, Frome, Trowbridge and Warminster encourage algae and moss. A spring or early summer clean gives you a head start before the worst regrowth. We use methods suited to local conditions and can advise on the best slot for your patio or decking.
