Our Natural Stone Cleaning Services:

Black Spot & Lichen Removal

We apply dedicated black spot remover to eliminate deep-rooted lichen that traditional jet washing can’t touch. This specialist chemical penetrates pores and lifts dark organic stains. It restores the original tone of natural stone without damage. Ideal for sandstone, limestone and patio slabs.

Low-Pressure Rotary Cleaning

We clean stone surfaces using soft rotary systems to avoid etching or surface abrasion. This method evenly lifts dirt and algae from textured surfaces. It’s far safer than high-pressure jetting, especially on fragile or aged stone. The result is a uniform, refreshed finish across the patio.

Biocide & Algae Treatments

After cleaning, we apply an HSE-approved biocide to neutralise algae spores and inhibit regrowth. This extends the life of the clean and keeps surfaces looking better for longer. It also helps kill off any residual organic material in hard-to-reach joints. Great for shaded, damp areas.

Rust, Efflorescence & Stain Removal

We offer targeted treatment for rust stains, cement smears, and white salt efflorescence. These issues can be common on porous stone or recently pointed joints. Our safe, pH-balanced formulas lift these blemishes without discolouring the stone. A professional solution for visible surface damage.

Nano Sealers & Preventative Care

We can apply breathable nano-sealers or colour-enhancing impregnators to protect the cleaned surface. These products help repel water, reduce algae regrowth and make future maintenance easier. For long-term care, we also offer an annual black spot preventer spray. No jet washing needed.
