Exterior Cleaning in Andergrove
Andergrove is an established suburb, and established suburbs have mature trees. That canopy is what makes the streets pleasant to live on and what makes exteriors here deteriorate faster than in newer estates.
Constant leaf drop feeds gutters and roof valleys. Shade holds moisture on surfaces long after the sun has dried out an exposed roof three streets away. Together they produce the two problems we see most in Andergrove: lichen colonies on roof tiles, and a persistent black staining on driveways and paths that never quite dries out.
Lichen Is Not a Stain, It Is a Plant
This is the thing most homeowners get wrong. Lichen is not dirt sitting on a tile; it is a living organism with a root structure that has physically bonded into the surface. Blasting it off with pressure removes the visible growth and leaves the root system behind, which is why it comes back within months and why the tile looks pitted afterwards.
We treat lichen chemically first. A biocide solution kills the organism through its full depth, then a controlled rinse takes the dead matter away. The surface is left intact and regrowth is measured in years rather than months.
Roofs, Driveways and Shaded Walls
On tiled roofs we work in two stages, kill then clear, and we check the condition of the tiles and pointing before we start. On Colorbond we softwash only; the coating is what protects the steel and it does not survive aggressive pressure.
Shaded south-facing walls get the same biocide treatment as roofs. If we only cleaned the visible green off, it would be back before the next wet season.
Common Questions
Will the treatment harm my garden?
No. We wet down vegetation before we start, use biodegradable solutions and rinse surrounding areas afterwards. Mature Andergrove gardens are exactly the situation we plan for.
How often do Andergrove roofs need doing?
With heavy tree cover, roughly every two to three years for tiles. Driveways under shade often need attention annually. They are the first thing to go green here.
