Patio Cleaning & Rotary Pressure Washing
Transform slippery, mossy, and lichen-stained garden patios with commercial 250-bar rotary flat surface cleaning and chemical black spot treatments.
Professional Patio Cleaning & Deep Surface Restoration
Over damp British autumns and winters, garden patios become coated in slippery green algae biofilms, stubborn black spot lichen, and deep-seated moss cushions that turn outdoor living spaces into unsightly slip hazards. Standard domestic electric pressure washers lack the water flow rate to clean evenly, often leaving unsightly zebra stripes and gouging soft stone mortar.
At WOW Roofers Ltd, our specialized patio cleaning service uses commercial-grade 250-bar petrol pressure washers, enclosed rotary flat surface cleaners, and professional biocide treatments.
We restore the original vibrant natural color of Indian sandstone, porcelain slabs, York stone, slate, and concrete pavers safely and efficiently with zero messy splashback onto your house walls or windows.
Eradicating Black Spot Lichen from Natural Stone
Why standard water pressure alone cannot remove stubborn black spots.
Black spots are resilient lichen (fungi and algae symbiosis) that anchor microscopic roots deep into the porous matrix of sandstone and paving slabs. High-pressure water merely tears the surface cap off, leaving the roots behind to regrow within weeks.
Our technicians apply an advanced active chemical biocide wash that dissolves lichen roots within the stone pores, followed by a heated rotary rinse that washes away all dead organic residue.
- ✓Penetrates deep into porous stone to eradicate stubborn black and white lichen spots
- ✓Gentle on delicate Indian sandstone bedding, preventing surface flaking or delamination
- ✓Low-pressure chemical soft washing protects fragile resin or sand-cement joint mortar
- ✓Restores original stone texture and natural mineral color variation
Long-Lasting Protection & Anti-Slip Finishes
Following the deep clean, we apply an anti-microbial biocide barrier that retards moss, algae, and weed recurrence for 12 to 24 months. We also offer premium breathable penetrating stone sealers for long-term oil, wine, and barbecue stain resistance.
- ✓Biocidal barrier keeps patios clear of green slime and slip hazards for 12–24 months
- ✓Improves garden safety for children, elderly family members, and outdoor entertaining
- ✓Optional breathable penetrating sealer enhances color and resists oil stains
- ✓100% self-contained mobile units with commercial water buffer tanks
💡 Key Takeaways

See why property owners across Birmingham and surrounding districts trust WOW Roofers Ltd for reliable roofline solutions.
“After high winds dislodged several ridge tiles on our roof, WOW Roofers arrived within 2 hours of calling. They made the roof watertight immediately and returned the following day to re-bed the tiles. Excellent communication, fair price, and zero mess left behind.”
“We needed a full re-roof on our 1930s semi. The team was prompt, polite, and worked relentlessly through freezing conditions. The quality of the new Marley tiles and dry ridge system is second to none, and knowing the team is fully insured provides real peace of mind.”
“Delighted with the roof soft washing and biocide treatment. Our roof looked tired and covered in thick moss. The technicians scraped it manually without pressure-damaging the tiles and applied a preventative wash. The house looks ten years newer!”
