Patio Cleaning
Removing Black Spot Algae, Lichen, Moss and Deep Outdoor Stains
Outdoor patio surfaces across Southampton, Portsmouth, Fareham, Waterlooville, and Havant accumulate organic black spot lichen, green algae, moss, and weather grime over time. Standard domestic pressure washers often fail to lift deep black spot spores embedded in stone pores.
Our patio cleaning service uses rotary flat-surface pressure washers combined with eco-friendly biocide treatments to remove lichen and algae completely. Once clean and dry, we offer protective breathable sealers to shield stone against future weather staining.
Patio Cleaning FAQs
Expert Answers to Your Patio Cleaning Questions
Read details on black spot removal, impregnating sealers, pressure washer safety, and drying times.
How do you remove stubborn black spot lichen from stone patios?
We apply specialist biocide chemical treatments that break down stubborn lichen roots before pressure washing.
What is an impregnating stone sealer?
Impregnating sealers soak deep into stone pores to repel water and oil while allowing natural moisture vapor to escape.
Will high-pressure jet washing damage patio pointing mortar?
Our flat-surface rotary pressure washers distribute water pressure evenly to protect sound pointing mortar joints.
How long after cleaning should a patio be sealed?
Patios must dry completely for 24 to 48 hours in fine weather before applying protective sealers.
How often should outdoor patio paving be cleaned?
A thorough clean every 12 to 24 months maintains vivid stone colors and suppresses moss and weed growth.
