Trusted Patio Cleaning in Boldon and the Surrounding Area

Patio cleaning across Boldon: biocide treatment for black spot lichen, gentle cleaning for sandstone and limestone, plus sealing advice. Fully insured team.

We use a softwash biocide treatment first, low-pressure or steam cleaning second, and only bring higher pressure in where the surface can genuinely take it - never as the default. That order matters: pressure without treatment just scatters lichen spores across the rest of the patio.

Proper treatment means killing the lichen and algae first with a biocide, letting it work, then cleaning the dead growth away. It takes longer than a straight pressure wash but it's the only approach that actually lasts.

Porous stone like sandstone and limestone soaks up dirt and organic growth differently to sealed porcelain or dense concrete, so we adjust pressure, chemical dwell time and rinse approach to the actual surface in front of us, not a one-size-fits-all wash.

Pressure Washing vs Our Treat-First Approach

A standard pressure wash blasts dirt and growth off the top of the stone using force alone. It's fast, and it looks dramatic, but on lichen-affected sandstone or limestone it can drive spores into the pores of the stone and damage soft pointing at the same time.

Our approach treats the biological growth chemically first, so it's actually dead before any pressure touches the surface. We then use the lowest pressure that gets the job done - often steam or a soft wash - which is gentler on the stone and the joints, and the clean lasts considerably longer as a result.
