Professional Soft House Washing for Northern Beaches Homes & Businesses
Coastal Clear Windows provides professional soft house washing across the Northern Beaches, Lower North Shore and Upper North Shore of Sydney. Using tailored low-pressure techniques and carefully selected cleaning solutions, we safely and effectively remove mould, algae, lichen, salt deposits and grime from your home's exterior — restoring its appearance without risk of damage to delicate or heritage surfaces.
Living on the Northern Beaches means living with one of Australia's most beautiful natural environments — but that same coastal environment is relentless on the exterior surfaces of your home. Salt air, coastal humidity, abundant rainfall, established vegetation and the proximity to bush all create ideal conditions for organic growth and surface deterioration that simply doesn't occur at the same rate in inland suburbs.
Mould and mildew thrive in the Northern Beaches’ humid coastal air — appearing as dark streaking and spotting on render, weatherboard, brick and cladding. Algae creates green and brown discolouration on walls, paths and roof surfaces. Lichen — the most stubborn of all organic growths — attaches firmly to render and masonry and causes genuine surface damage if left untreated. Salt deposits from ocean air accumulate on all exterior surfaces, accelerating deterioration and causing a dull, hazy appearance even on recently painted homes.
Many Northern Beaches homeowners reach for a high-pressure washer to tackle these problems – but high pressure washing on residential surfaces causes more problems than it solves. It forces water into wall cavities, damages render and mortar, strips paint, and can permanently damage timber weatherboards and delicate heritage surfaces. Soft washing is the professional solution – effective, safe and appropriate for all surface types.
WHAT IS SOFT WASHING?
Soft washing is a professional exterior cleaning method that uses low water pressure — similar to a garden hose — combined with carefully selected biodegradable cleaning solutions to safely remove organic growth, salt deposits and surface grime from exterior surfaces.
Unlike high-pressure washing which physically blasts contaminants off surfaces — often causing damage in the process — soft washing treats the biological source of the problem. The cleaning solutions we use penetrate organic growth at a cellular level, killing mould, algae and lichen at the root rather than just removing what’s visible on the surface. The result is a deeper, longer-lasting clean that doesn’t damage your home’s exterior.
Soft washing is safe for all exterior surfaces including render, brick, weatherboard, Hardiplank, timber, painted surfaces, roof tiles, Colorbond, sandstone and heritage masonry.
Our Xero soft, extendable brushes are the state of the art cleaning technology to get to hard to reach places – and are as perfect for windows as they are for soft washing the exterior of your house.
OUR SOFT HOUSE WASHING PROCESS
We begin with a thorough inspection of your home's exterior, identifying the types and extent of organic growth and surface soiling, checking for any pre-existing damage, and noting any areas requiring particular care — heritage surfaces, delicate paintwork, garden beds below treatment areas.
Before applying any cleaning solutions we protect garden beds, plants, outdoor furniture and any surfaces that shouldn't be treated. We wet down surrounding vegetation to dilute any overspray and protect your garden during the cleaning process.
We apply our carefully selected biodegradable cleaning solutions to all exterior surfaces using low-pressure equipment. The solutions penetrate organic growth — mould, algae, lichen — killing it at the root and loosening salt deposits and surface grime for easy removal.
We allow the cleaning solutions to work for the appropriate dwell time depending on the level of soiling and the surface type. This is what makes soft washing so effective — the treatment does the work, not the pressure.
A thorough low-pressure rinse removes all loosened organic matter, cleaning solution residue and surface grime. The result is a visibly transformed exterior that's been treated at the source — not just surface cleaned.
We inspect the completed work with you, point out any areas of note and provide recommendations for maintenance frequency based on your property's specific exposure and surface types.
Before professional soft house washing Northern Beaches homes typically show dark mould streaking on render and cladding, green algae discolouration on shaded walls and lower elevations, lichen patches on render and brick, and a general dullness and discolouration that makes even well-maintained homes look tired and neglected.
After our professional soft wash the transformation is dramatic — often described by customers as looking like the house has had a complete repaint. Original surface colours are restored, organic growth is eliminated at the root, and the home's exterior looks fresh, clean and well-maintained. The results typically last 12-24 months depending on the level of sun exposure, moisture and surrounding vegetation.
As a general guide for Northern Beaches properties:
For most Northern Beaches properties we recommend soft house washing every 12-18 months. However the ideal frequency depends on your specific situation:
Properties in shaded aspects with limited sun exposure — particularly south-facing walls and homes surrounded by established trees — may require more frequent treatment as shade and moisture encourage faster organic regrowth.
Properties close to the ocean or other bodies of water face higher salt air exposure and may benefit from more frequent treatment to address accelerated surface soiling.
Properties with significant north-facing sun exposure and good airflow typically maintain their appearance longer between treatments as sunlight and airflow inhibit organic growth.
We’ll assess your property’s specific situation and recommend the right maintenance schedule when we quote.
Pressure washing uses high-pressure water — typically 1500-3000 PSI — to physically blast contaminants off surfaces. This is effective for very hard surfaces like concrete driveways but damages render, brick mortar, weatherboard, painted surfaces and heritage masonry. Soft washing uses low pressure — similar to a garden hose — combined with biodegradable cleaning solutions that kill organic growth at the root. It’s safer, more effective and longer lasting for all residential exterior surfaces.
Yes — we take specific precautions to protect your garden during every soft wash. We wet down surrounding vegetation before treatment, apply cleaning solutions carefully to avoid overspray onto garden beds, and thoroughly rinse surrounding areas after treatment. Our biodegradable cleaning solutions break down rapidly and are safe for established gardens when applied and rinsed correctly.
No — soft washing is specifically designed to be safe for all exterior surfaces including render, brick, weatherboard, painted surfaces and heritage masonry. Unlike high-pressure washing which can crack render, force water into wall cavities and strip paint, soft washing uses only gentle pressure and surface-safe cleaning solutions.
Most standard residential properties take between 2 and 4 hours depending on the size of the home and the extent of soiling. We’ll give you a time estimate when we quote.
Not necessarily — many customers arrange access while they’re at work. We’ll confirm arrangements with you beforehand and contact you when the job is complete.
Results typically last 12-24 months depending on your property’s aspect, sun exposure, proximity to the coast and surrounding vegetation. We’ll recommend the right maintenance schedule for your specific property.
