At its core, patio jet washing is about restoring the surface, not just “blasting it clean.”

• Removes algae, moss, and lichen (that green layer you see)
• Lifts ground-in dirt and weather staining
• Brings the original colour of the slabs back out
• Makes the surface safer (less slippery when wet)

What makes a proper job (like yours)

From your before/after:

• Evenly clean across all slabs (no zebra striping)
• Edges and joints cleaned properly
• No visible damage or scarring to the stone
• Natural colour restored—not over-etched

That tells me it’s been done with the right pressure and technique, not just full power blasting.

Why customers care

• It can make a patio look new again without replacement
• Big visual impact for relatively low cost
• Improves overall garden appearance instantly
• Often adds value before selling or renting

The simple way to explain it to a customer
