Ready for summer

Signs your patio needs cleaning

Patios in the shade go downhill fast, especially after a wet winter.

  • Green and slippery

    Algae turns slabs green and dangerous underfoot.

  • Lichen and staining

    Yellow and dark spots are usually lichen, which needs treating rather than just washing.

  • Weeds in the joints

    Moss and weeds filling the gaps between slabs.

  • Faded, tired stone

    Stone that has lost its colour under a film of dirt.

The right clean for every stone

Sandstone, porcelain and concrete all need a different approach. Get it wrong and you can damage the surface.

All FAQs
Can you clean sandstone and porcelain patios?

Yes. We match the method to the stone, because sandstone and porcelain need a different approach to concrete slabs.

What are the black spots on my patio?

They're usually lichen. It grips the stone, so it needs treating rather than just washing.

Will my patio be less slippery afterwards?

Yes. Removing the algae and moss that make it slippery is a big part of the clean.

Do I need to move my garden furniture?

We're happy to move furniture and pots ourselves. Just let us know about anything fragile.
