Professional soft washing removes dirt, grime, moss, mold, and weathering from your home's exterior while protecting delicate surfaces.
Your home is your most significant investment. The exterior is constantly exposed to harsh elements—wind, rain, UV rays, and the damp climate of Queenstown, Wanaka, and Otago & Southland—that accumulate dirt, moss, algae, mold, and weathering. Professional house soft washing safely restores your home's appearance and protects its value.
We specialize in soft washing, not pressure washing. Our carefully calibrated low-pressure techniques combined with controlled cleaning solutions effectively remove all organic growth and staining without damaging painted surfaces, rendered finishes, or delicate exterior materials. This is premium care for your home.
Guardian Wash serves homeowners, property managers, Airbnb owners, and holiday home operators across Queenstown, Wanaka, Invercargill, and wider Otago & Southland, providing reliable, professional house washing that reflects our commitment to quality and care.

Mold growth near entryways and windows poses potential health risks to your family

Guardian Wash believes in transparency about our cleaning methods. For house washing, we use a professional soft washing process with carefully calibrated solutions, applied using controlled low-pressure methods. This approach treats organic growth such as mould, moss, algae, grime and cobwebs without blasting delicate exterior surfaces.
Before and after application, we thoroughly rinse nearby plants, gardens and sensitive areas with water to help protect the property. We adjust our process depending on the surface type, condition, property access and surrounding environment. This professional, transparent approach ensures your home receives the exact care it needs while protecting what matters most to you.
We focus on being responsible stewards of your property and environment. Our pre-rinsing and post-rinsing practices, combined with careful application, mean your landscaping and garden areas are protected throughout the cleaning process.
We recommend professional house washing every 12-18 months depending on climate, shade, and tree coverage. Properties with more moss or mold growth may benefit from annual cleaning.
