What Happens During a Professional Patio Clean?

A professional patio clean begins with an assessment of the surface type and condition. This determines the pressure settings and cleaning products to use. Indian sandstone, porcelain, concrete slabs, and natural stone all require slightly different approaches. We identify any areas of particular concern — heavy black spot growth, lifting slabs, or badly eroded joints — and discuss them with you.

Pre-treatment chemicals are applied where needed. A biocidal solution is applied to surfaces with significant moss or algae growth to kill the organisms and loosen their hold on the surface. After the dwell time, the rotary surface cleaner is used systematically across the patio. The spinning action delivers an even clean across every slab without streaking.

Edge work is completed by hand with the pressure lance to clean borders, steps, and areas around planters or garden furniture that the surface cleaner can't reach. Joints are flushed clean and the whole surface is rinsed down. We tidy up and carry out a final check. The improvement is often remarkable — customers frequently comment that their patio looks better than it has in years.
