What is the difference between soft washing and water blasting?

Water blasting uses high pressure, which strips paint, forces water behind cladding and leaves the mould spores in place so it grows straight back. Soft washing applies a treatment that kills the growth at the root, then rinses at low pressure. It lasts longer and is safe on the building envelope.

Will the treatment harm plants or stormwater?

Plants and gardens are rinsed before and after, and runoff is controlled and contained so nothing goes into the stormwater system that should not.

Soft Wash

Low Pressure, Treatment Based, Longer Lasting

High pressure strips paint, forces water behind cladding and leaves the spores in place so it grows straight back. Treatment based washing does not.

Cladding And Building Envelope

A treatment is applied, given time to work through the growth, then rinsed at low pressure. Works on plaster, weatherboard, precast, metal cladding and painted surfaces without damaging the coating.

Mould, lichen and algae killed at the root
Soffits, fascia and canopies
No high pressure on the envelope

Roofs, Gutters And Hardstand

Roof moss treated so it dies off and washes away with the rain, gutters cleared, and paths, loading bays and carparks washed down. Runoff is managed so nothing goes into the stormwater it should not.

The Detail

Scope, Access And Timing

We visit, measure the building, check access for elevated work platforms, and confirm water and power availability. You get a fixed price and a date, not a day rate.

Most commercial washing is done over a weekend so staff, customers and vehicles are not in the way. Access equipment is arranged and included in the quote.

Auckland's humidity means most buildings need this every twelve to eighteen months. We will tell you what your site realistically needs rather than selling you a contract you do not.
