House Soft Wash Auckland
1.5% SH Mix · Low Pressure Under 500 PSI
Your home's exterior takes a beating from Auckland's subtropical climate. Moisture, salt-laden wind, and shade create the perfect breeding ground for moss, algae, and black mould that eat into paintwork and cladding over time. A standard garden hose won't shift it, and high-pressure blasting risks cracking weatherboards and forcing water behind the building envelope. That's where soft washing comes in.
What Is Soft Washing?
Soft washing uses a carefully calibrated 1.5% sodium hypochlorite (SH) solution applied at low pressure — always under 500 PSI. The chemical does the heavy lifting, penetrating the root system of organic growth so it doesn't simply regrow within weeks. We rinse at gentle pressure, protecting your paint, timber, and joinery throughout the process.
Safe for All Auckland Cladding
Whether your home features Hardie plank, cedar weatherboards, painted brick, plastered block, or lightweight concrete panels, our soft wash method is safe for every surface. The low-pressure technique eliminates the risk of water ingress through joints and cavities — a common problem with traditional pressure washing. We've treated hundreds of homes across the North Shore, Central Auckland, and the wider region.
Kills Moss and Algae at the Root
The difference between a soft wash and a pressure wash is longevity. Pressure alone strips the surface layer but leaves the root system intact, meaning regrowth appears within weeks. Our SH solution kills organic matter at its source. Most homes stay visibly cleaner for 12 months or longer — and we back that with our written guarantee.
The BlueHawk Rig
Every Wash Method job is powered by the BlueHawk — our purpose-built, trailer-mounted cleaning rig. It carries its own water supply, a commercial-grade 4000 PSI pump (dialled down for soft wash work), chemical dosing system, and all hoses and lances needed for a complete clean. No running your garden tap dry, no extension leads across your lawn.
Auckland Council Compliant
We use biodegradable, environmentally responsible products and follow Auckland Council guidelines for stormwater management. Run-off is contained and neutralised where required, and all chemical concentrations sit within approved thresholds. You can be confident your property is cleaned properly and responsibly.
Pricing
House soft wash starts from $350 + GST for a standard single-storey home. Multi-storey, large footprint, or heavily soiled properties are quoted individually after a free on-site assessment. We provide a written quote before any work begins — no surprises.
