Is Your Patio Telling You It Needs a Clean?

Green or black slippery patches are the clearest sign that your patio needs attention. Algae and moss grow steadily in damp conditions and once they've taken hold across a significant portion of your patio, a garden hose and brush won't be enough to remove them. Professional cleaning with the right equipment and products is needed to clear them properly.

Discolouration and dullness are also common indicators. Natural stone patios like Indian sandstone and limestone lose their vibrant colour as algae and surface dirt build up. If your patio used to look bright and warm but now looks flat and grey, cleaning will restore the original colour and texture dramatically.

Black spot — a dark mould that appears in small dots across patio surfaces — is another sign that your patio needs professional attention. Black spot is more resistant than surface algae and requires specialist treatment to remove. If left unchecked it can etch into stone and cause permanent staining. The sooner it's treated, the easier it is to remove completely.
