How we operate

The principles that guide every job.

  • Fixed quotes in writing, in 24 hours

    Every job is priced per surface — square metreage, condition, access — not per hour. The number you see on the quote is the number you pay. Quotes are returned within 24 business hours of enquiry.

  • Right method for the surface

    Soft wash for any surface where high pressure would do damage (render, paint, weatherboard, fibre cement, roof tiles). Pressure wash for what you walk or drive on (concrete, pavers, retaining walls). Deionised water for glass and solar.

  • Photo-documented work

    Gutter cleans, strata cycles and any commercial scope are documented with before-and-after photos sent with the invoice — useful for landlords, body corporate compliance and insurance records.

  • 24-hour satisfaction guarantee

    If you’re not happy with the finish, tell us within 24 hours and we’ll come back and fix it at no extra cost. We don’t consider a job done until you’re happy.

Methodology

The right method for every surface.

Most exterior cleaning failures come from using the wrong tool on the wrong surface — pressure-washing render and stripping the coating, blasting roof tiles loose, scratching coated glass with stiff brushes. Our entire process is built around matching method to substrate, not the other way around.

  • Soft washing (under 500 PSI)

    Render, paint, weatherboard, fibre cement, roof tiles and building facades. Detergent-led — chemistry kills mould and algae at the spore level.

  • Pressure washing (1,500–4,000 PSI)

    Concrete, exposed aggregate, pavers, retaining walls, driveways and pool surrounds. Surface-cleaner-led for even results without zebra striping.

  • Deionised water + soft brushes

    Solar panels, glass facades and high-rise windows. Mineral-free water dries with no spotting; warranty-safe on PV.

  • EWP and rope access (heights)

    EWP for buildings to 3 storeys; hired access for higher work. Site-specific SWMS issued before every working-at-heights job.

Where we work

South East Queensland — two metro hubs.

We operate from a Brisbane base across two metro markets in South East Queensland. Brisbane is the primary service area with same-week scheduling for residential. The Sunshine Coast is run as weekly batched trips so multiple jobs share the travel time.

What we clean

Nine exterior cleaning services.

Every service we offer is exterior. We don’t do interior cleaning, garden work or pest control — exterior surface care is the only thing we do, and the only thing we want to do.
