We wash commercial building exteriors throughout Brisbane — from two-storey office blocks on the northside through to multi-level retail complexes in the CBD and industrial facades out west. Our soft wash systems deliver sodium hypochlorite and surfactant solutions at low pressure to kill mould and algae on rendered, painted and cladded surfaces without stripping coatings or forcing water behind flashings. For tougher contamination like atmospheric carbon staining on concrete panels, we step up to medium-pressure cleaning at 2,000–3,000 PSI with appropriate fan tips. We carry $20M public liability, provide full Safe Work Method Statements, and can coordinate boom lift or rope access for buildings above two storeys. Every job is backed by our satisfaction guarantee.

What's Included
Your commercial building wash includes a pre-clean inspection to assess surface types, contamination severity and access requirements. We supply all equipment, chemicals, safety barriers and signage — you just need to provide access to a water supply. The wash covers all exterior walls, fascia, soffits, gutters and downpipes within the agreed scope. We pre-treat heavy mould and algae growth with a targeted biocide application to ensure a lasting result, not just a surface-level rinse. You receive before-and-after photos and a written report suitable for property management files or tenant communication.
Surfaces We Clean
Commercial buildings in Brisbane come in every finish imaginable, and we have the right method for each one. Acrylic-rendered walls get soft washed at under 1,000 PSI to avoid pitting or water ingress. Face brick and block handle medium pressure with a fan tip for even coverage. Painted Colorbond and metal cladding panels are soft washed with a low-concentration sodium hypochlorite mix to remove mould without affecting paint adhesion. Concrete tilt panels, precast facades and exposed aggregate respond well to higher pressure combined with a commercial degreaser. We always test an inconspicuous section first to confirm the method before scaling up.
Our Method (Soft Wash / Pressure Wash)
We begin with a full perimeter walk to document surface conditions, identify any existing damage, and plan chemical run-off management. Biological growth — mould, algae and lichen — is pre-treated with a sodium hypochlorite solution and left to dwell for 10 to 15 minutes to break down at the root level. We then wash each section systematically from top to bottom, adjusting pressure and tip selection for each surface type. Rinse water is contained or directed to sewer-connected drains in line with Brisbane City Council trade waste guidelines. Final inspection with the property manager ensures every area meets the agreed standard.
Why Brisbane Properties Need This
Brisbane’s warm, humid climate means commercial building facades cop a hiding — particularly south-facing and shaded walls that stay damp longer. Black mould and green algae can establish within weeks during the wet season, and once embedded in porous render, they spread fast. UV degradation chalks painted surfaces, trapping dirt and making buildings look years older than they are. Storm season brings organic debris, leaf tannin staining and wind-driven grime. Regular building washing maintains your asset’s presentation, protects surface coatings, and avoids costly repainting or render repairs down the track.

Frequently Asked Questions
How much does commercial building washing cost in Brisbane?
Pricing depends on the building size, number of storeys, surface type and access requirements. A single-storey commercial unit might start from a few hundred dollars, while a multi-storey office block requiring boom lift access will be significantly more. We provide free on-site quotes with a detailed written scope — call us on 1300 580 435 or email [email protected] and we will get back to you within 24 hours.
Will pressure washing damage the render on my commercial building?
Not when it is done properly. We soft wash rendered surfaces at under 1,000 PSI — well below the threshold that causes pitting or water penetration. The cleaning is done with sodium hypochlorite solutions that kill biological growth chemically rather than blasting it off mechanically. We have washed hundreds of rendered commercial buildings across Brisbane without a single damage claim.
Can you wash a commercial building while it is occupied?
Yes — we do it every week. We coordinate with your property manager to schedule work around tenant access, deliveries and peak trading times. Safety barriers and signage are set up to protect pedestrians, and we manage chemical overspray to avoid contact with vehicles, outdoor furniture and landscaping. Most tenants barely notice we are there.
How long does a commercial building wash take?
A standard single-storey commercial unit takes half a day. A multi-storey building or large complex may take one to three days depending on access, contamination levels and the number of surface types involved. We provide a timeframe estimate in your quote so you can plan accordingly.
Do you provide ongoing maintenance washing contracts?
We do. Many Brisbane property managers and building owners set up quarterly or six-monthly maintenance washes to keep facades consistently clean. Maintenance contracts lock in your pricing, guarantee scheduling priority and keep your building looking sharp year-round. We will recommend a frequency based on your building’s orientation, surroundings and surface types after the initial clean.
