House washing in Randwick
The common Randwick exterior job is a soft wash of a Federation or Inter-War house whose rendered or face-brick walls have gone green and black on the shaded side, with tannin streaks below the gutters and lichen creeping across sandstone footings and garden walls. Victorian villas add stone facades that must be cleaned gently, and slate or terracotta roofs that should not be walked on. Gutters clog under street figs and other mature trees, and solar panels dull under dust and pollen rather than salt. Apartment blocks need facades, stairwells, bin areas and shared paths washed on a schedule, with sandstone fences at the street treated as heritage fabric.
A vetted tradie chooses low pressure and a biocidal treatment for growth, a mild detergent for grime, and brushes and poultices on sandstone, never a high-pressure jet or acid on heritage stone. Wash water with detergent or sediment cannot be let into the stormwater drains under NSW environmental law, so it is diverted to lawn or captured, and kerb inlets are protected. Roofs and upper walls are reached with poles from the ground or with the fall protection required by the WHS Regulation, and fragile slate is treated from the gutter line rather than walked. If a pre-1990 house shows fibro eaves or a fibro garage, asbestos cement is left untouched and flagged.
Post the job with photos of the shaded elevation, the roof and the street frontage, and say if the house is in a conservation area or listed, so the tradie plans accordingly. We match it with vetted exterior cleaning tradies who already work in Randwick and nearby, and they inspect and quote in writing, surface by surface, with the method, the wash water plan and any access equipment named. For strata blocks the quote can be addressed to the owners corporation. The match costs nothing and commits you to nothing. Autumn and winter, after the leaf drop, are good times to combine a gutter clean with a wash.

Frequently asked questions
Cleaning that does not change the fabric, such as a soft wash, usually does not, but check with Randwick Council if you are unsure, and always before stripping paint, repointing or applying coatings to sandstone.
Slowly. The tradie applies a biocide and leaves it to kill the growth over a few weeks, then rinses at low pressure. Scrubbing hard or using a pressure jet would take the stone's surface with the lichen, so patience is the method.
Twice a year is common on Randwick streets with heavy canopy, and more often if the downpipes block. Gutter guard reduces the frequency, and a handyman can fit it.
The owners corporation, because stairwells, paths and the facade are common property. One owner can collect quotes and take them to the strata manager.
