House washing in Duffys Forest
A Duffys Forest house gathers mould and lichen on every shaded face, tannin streaks below the eaves where leaves sit, brown stains on sandstone and concrete, and a film of dust and soot on render and glass after a dry spell or a burn. Roofs are large, often with solar arrays, and their gutters and valleys fill with gum leaves and bark that both block flow and feed embers. Where the roof feeds a drinking water tank, clean gutters and a working first-flush diverter decide what ends up in the tank. Decks, pergolas, pool surrounds, stables and studios share the same conditions, and many owners want the whole property done in one visit before summer.
A vetted tradie plans the job around your water and wastewater. On tank supply they bring water or agree a volume; detergent and wash water are kept out of septic trenches and directed to lawn that does not drain toward the bush, the national park boundary or a dam. Render, weatherboard and any pre-1990 fibro is soft washed, and asbestos cement is never pressure cleaned. Biocides for mould get dwell time rather than force. Roof and gutter work uses anchors, edge protection or poles as the WHS Regulation requires. Where the tank inlet cannot be isolated, the tradie diverts the downpipes during the clean so dirty water does not enter it.
Tell us what needs cleaning, whether the roof feeds a tank, whether you have mains water, and how a vehicle reaches the house. Vetted, independent tradies who already clean homes in Duffys Forest and Terrey Hills receive the job, come out to look and quote in writing, listing surfaces and methods, water supply and containment, tank isolation, gutter and solar cleaning if wanted, and timing around fire season and burns. Owners often ask for photos of the roof and gutters afterwards. Nothing is charged to homeowners, and every quote can be refused.

Frequently asked questions
Not if the downpipes are diverted or the tank inlet is closed during the clean and gutters are flushed before reconnection. Ask the tradie to confirm the step in the quote.
Yes. Panels get soft brushes and deionised water, usually from a pole or with fall protection on the roof, and the output difference is often visible on the inverter.
Run-off is kept well inside the property, products are not sprayed toward native vegetation, and nothing is left on the ground. Tradies in the network treat it as a condition of the job.
Late winter or spring, before the fire danger period and after most leaf drop, with a lighter gutter check in autumn. Avoid days immediately after a burn until ash has settled.
