About this service
Patios pick up everything the garden throws at them: moss in the joints, green algae in the shade, black spot lichen on sandstone, and a general grey film that makes even a lovely Indian stone patio look dull.
Every stone needs a different approach. Porcelain and concrete take a rotary clean; sandstone and limestone need lower pressure and a dedicated black-spot treatment; slate needs care around its layers. We match the method to your patio and finish with re-sanding or advice on re-pointing, plus optional Smartseal sealing to keep the colour up and the lichen off.
Part of Driveways & Patios. Rotary surface cleaning for driveways, patios, paths and decking, followed by re-sanding and optional Smartseal sealing so the finish lasts and the weeds stay away.

Why it matters
The black-spot problem
- 01
Black spot is a lichen with roots that grow into the surface of sandstone and limestone.
- 02
Pressure washing alone removes the top of it and leaves the spots looking as bad within weeks.
- 03
Only a dedicated treatment kills the lichen at the root and lets the stone come clean.
- 04
Once treated and sealed, the surface is far harder for lichen to re-colonise.

Our patios process
- 01
Identify the stone
Sandstone, limestone, slate, porcelain, concrete or brick — the pressure, technique and products are chosen to suit.
- 02
Treat
Moss, algae and black spot are treated so the growth is killed rather than just trimmed.

Clean
Rotary cleaner or low-pressure lance across the patio, with the joints protected from wash-out where mortared.

Finish
Re-sand or advise on re-pointing, rinse down, and seal on a dry return visit if chosen.

FAQs
Patios questions
Yes, with the right treatment and a little patience — heavy infestations sometimes need a second application. It cannot be removed by pressure alone.
