Garden Maintenance
Pressure Washing
Over time, patios, paths and driveways accumulate algae, moss, lichen and general grime that make them look dull, neglected and potentially slippery. A thorough pressure wash can transform the appearance of your hard landscaping in a matter of hours, at a fraction of the cost of replacement.

Over time, patios, paths and driveways accumulate algae, moss, lichen and general grime that make them look dull, neglected and potentially slippery. A thorough pressure wash can transform the appearance of your hard landscaping in a matter of hours, at a fraction of the cost of replacement.
We carry out pressure washing as a standalone service or as part of an annual maintenance schedule, and can treat a wide range of surfaces including natural stone, porcelain, concrete pavers, block paving and resin bound gravel.

Patio, Path & Driveway Cleaning
We use professional hot and cold water pressure washers calibrated to the appropriate pressure for each surface type — powerful enough to remove embedded dirt and biological growth without damaging the surface or disturbing jointing sand.
Before washing, we apply a pre-treatment biocide to break down stubborn algae and lichen, which significantly improves the final result and reduces the risk of regrowth. All waste water and loosened debris is swept clear and removed from the site.
Aftercare & Ongoing Treatment
After pressure washing, we recommend applying a post-treatment algaecide sealer to stone and concrete surfaces. This penetrates the surface and significantly extends the time before biological regrowth returns — in some cases protecting for two to three years rather than six to twelve months.
For block paving, we re-apply kiln-dried jointing sand after washing to stabilise the blocks, fill any gaps that have opened up and restore the tight, neat appearance of the finished surface. We can also re-seal block paving to lock the sand in place and protect against oil and staining.
