House washing is the process of cleaning a home's exterior walls, eaves, fascia, and soffits using low-pressure softwash methods that safely remove mould, algae, dirt, and salt deposits without damaging paint, render, or cladding. For homes along the NSW coast, regular house washing protects your biggest asset from the accelerated deterioration caused by salt air, humidity, and biological growth.
The exterior of your home is constantly exposed to the elements. Along the Central Coast, Sydney, and Newcastle, onshore winds carry salt aerosol that coats wall surfaces and draws moisture into render and paint systems. Left untreated, this leads to mould penetration, paint breakdown, and staining that becomes progressively harder to remove. Regular house washing prevents this cycle and keeps your home looking its best.
Surface Types We Wash
SOAKD washes every common residential exterior surface found across Sydney, the Central Coast, Newcastle, and the Hunter Valley:
- Rendered walls: Cement render, acrylic render, and textured coatings are cleaned using low-pressure softwash to remove algae, mould, and salt staining without damaging the render surface or breaking the protective seal.
- Weatherboard: Timber and composite weatherboard homes are softwashed to remove grime, mould, and oxidation. We clean between boards and around joins where biological growth accumulates.
- Fibre cement cladding: James Hardie and similar cladding products are cleaned using low-pressure methods that preserve the factory finish and prevent moisture penetration at joins and edges.
- Brick: Face brick and recycled brick exteriors are cleaned to remove mortar staining, efflorescence, algae, and atmospheric soiling. We calibrate pressure based on the brick type and mortar condition.
- Painted surfaces: All painted exterior walls are softwashed to prevent paint stripping. We match our cleaning solution to the paint type and condition, removing surface contamination while preserving the coating.
House Washing Cost Guide
House washing on the Central Coast, Sydney, and Newcastle typically falls within these ranges:
- Single-storey house: $450 to $700 depending on size and surface condition
- Two-storey house: $650 to $1,100 depending on access requirements and surface area
- Large or multi-level home: $900 to $2,500 depending on complexity and height access needs
Pricing varies based on the home's total wall area, number of surface types, level of staining, and access conditions. We provide free on-site quotes so you know the exact cost before any work begins.
How Often Should You Wash Your House?
Homeowners on the Central Coast, Sydney coastline, and Newcastle should wash their house exterior every 12 to 18 months to prevent cumulative salt and mould damage. Properties further inland or in sheltered positions can typically extend to every 2 to 3 years.
Signs your house needs washing include visible mould or green algae on walls, streaking below window sills and gutters, discolouration on the south or shaded side of the house, and a general dull or grimy appearance that hosing does not remove.
The SecureClean Process for House Washing
- Property Assessment: We inspect every exterior surface of your home, identify staining types and biological growth, assess paint and render condition, and determine the safest cleaning method for each material. Any existing damage is noted and photographed.
- Surface Protection: Windows, garden beds, outdoor furniture, fixtures, and any sensitive areas are covered and protected before cleaning begins. Downpipes and stormwater outlets are checked to manage water runoff.
- House Wash Treatment: Low-pressure softwash is applied systematically to all wall surfaces, working from top to bottom in controlled sections. Salt, mould, dirt, algae, and atmospheric deposits are removed without stripping paint or damaging coatings.
- Final Inspection: Complete walkthrough of your home checking every wall section, corner, and detail. Photo documentation provided showing the results. We recommend a maintenance schedule based on your home's location and coastal exposure.
