Green algae on driveways, paths and concrete surfaces is one of the most common exterior cleaning issues in Queensland, particularly in shaded areas, near garden beds and on the shaded sides of properties. Beyond aesthetics, algae-covered concrete is legitimately dangerous — it becomes extremely slippery when wet and is a common cause of slips and falls, particularly for elderly residents and children. Queensland's humidity and rainfall create near-perfect conditions for algae to establish on concrete, pavers and exposed aggregate, and once established it spreads quickly. Professional pressure cleaning combined with a soft wash biocide treatment removes algae completely and significantly slows regrowth.
Shaded concrete retains moisture for longer periods, and Queensland's humidity means surfaces stay damp even between rain events. This creates ideal conditions for algae to establish on any concrete, paver or exposed aggregate surface. Properties with mature trees overhead, shaded garages and south-facing paths are particularly susceptible. Concrete is also naturally porous — algae roots into the surface rather than sitting on top, which is why a garden hose won't remove it.
Algae-covered concrete and pavers can be as slippery as ice when wet. In Queensland where afternoon storms are frequent throughout summer, a path or driveway that looks manageable in dry conditions can become extremely hazardous after rain. If you've noticed green growth on any walkway, path or driveway, having it cleaned is a genuine safety priority, not just an aesthetic choice.
After cleaning, concrete driveways and paths can be sealed to significantly slow algae regrowth. Sealing fills the porous surface that algae roots into, making it harder for growth to re-establish and easier to clean when it does. Ask about sealing options when requesting your quote.
Driveways, paths, patios, pool surrounds, entertaining areas, exposed aggregate, pavers and concrete steps — any outdoor surface that's developed algae or general grime. We use the appropriate pressure and method for each surface type.
Yes — algae-covered concrete and pavers are extremely slippery when wet and a common cause of slips and falls. Having it professionally cleaned is a safety priority, particularly if you have elderly family members or children.
Typically 12 to 18 months before significant algae regrowth occurs. Shaded driveways may need more frequent attention. Sealing after cleaning can extend results significantly.
Yes — pavers, exposed aggregate, brushed concrete and plain concrete are all surfaces we clean regularly. We adjust the pressure and method to suit each surface type.
Driveway cleaning is often included as an add-on to a house wash or roof clean at significant savings. Standalone driveway cleans depend on size. Contact us for a free quote.
