Surrey sits in the south-east of England, where mild, damp winters combined with summer humidity create ideal conditions for algae, moss and lichen growth on outdoor surfaces. Patios and driveways in Surrey — particularly those in shaded spots common in the county’s wooded areas around Haslemere, Cranleigh, Dorking and the Surrey Hills — can develop a green, slippery coating over a single winter season.

This is not merely cosmetic. Algae on patio slabs and decking is genuinely dangerous — it creates a slip hazard in wet conditions that insurance companies increasingly flag as a homeowner liability. Our jet washing service removes algae down to the surface level, and we can apply a biocide treatment that inhibits regrowth for 12–18 months.

For driveways, the combination of Surrey’s clay soils, heavy leaf fall from deciduous trees and urban pollution creates tannin staining and deep-seated discolouration on block paving and concrete that ordinary domestic pressure washers cannot remove. Our commercial-grade machines operate at pressures and flow rates that lift this contamination reliably without damaging the surface.
