Southern Suburbs
Green on the south wall, grey-green crust on the roof, concrete that has changed colour — in Harristown that is the climate, not neglect. This is the high southern end of the city — coldest, dampest, longest dew. Exactly the climate mould, algae and lichen want. $20 million public liability, Working at Heights certified, police-checked crew and a signed SWMS on every site.
Why us here
We work Harristown regularly, so a quote rarely means a long wait. What matters most is method: concrete, pavers and brickwork take pressure cleaning; render, paint, weatherboard, Colorbond and roofs take soft washing, where the treatment kills mould and lichen at the root rather than blasting the surface off. Firm price before we start, photos when it is done.
Local conditions here
Red Ferrosol · black clay in low spots
Red Ferrosol here: fine iron-rich clay that soaks into bare concrete instead of sitting on top, which is why hosing a stained driveway does nothing. Lifting it needs a surface cleaner; sealing afterwards stops it going back in.
This is the high southern end of the city — coldest, dampest, longest dew. Exactly the climate mould, algae and lichen want.
Harristown is an established inner-south suburb with a real mix of long-held family homes and rental properties.
Through the year
What the walls and concrete are telling you
Green or black film on the south and east walls is mould, not dirt — it needs a treatment, not a blast. Grey-green crust on the roof is lichen, bonded into the tile. Water spilling over a gutter edge is going into the fascia. A driveway that has changed colour is this ground at work. Streaky glass is mineral film. A solar array quietly making less than it used to is usually just soiled.
Most often in Harristown: roof cleaning, exterior house washing, soft washing. Also gutter cleaning, driveway and path cleaning, window cleaning. Book several in one visit — cheaper, and the order matters: roof, gutters, walls, then windows.
