Commercial & strata pressure cleaning in Canberra

Commercial and strata pressure cleaning is a different discipline from residential work. The cleaning technique is much the same; the scheduling, access, compliance and documentation around it are not. If you manage a scheme, a retail site or a commercial building in Canberra, here's what the job should look like.

Who this applies to

• Strata schemes and owners corporations — common driveways, visitor parking, walkways, stairwells, bin bays and external common walls.
• Commercial and retail landlords — forecourts, entries, awnings, signage surrounds and loading docks.
• Hospitality — alfresco areas, outdoor dining paving, kitchen exhaust surrounds and grease-affected concrete.
• Schools, clubs and community facilities — courts, playground soft-fall surrounds, covered walkways and shade structures.
• Real estate and facilities managers — between-tenancy makegoods and presentation for listings.

What typically gets cleaned

Area	Why it matters	Typical frequency
Car parks & driveways	Oil, tyre rubber, dust; presentation from the street	6–12 months
Common walkways & stairs	Slip risk from algae and lichen	6–12 months
Bin bays & waste areas	Odour, pests, leachate staining	Quarterly or monthly
Entries, lobbies & forecourts	First impression; heavy foot traffic	3–6 months
External walls & render	Mould and pollution film	12–24 months (soft wash)
Awnings, signage & shade sails	Grime dulls branding and fabric	12 months
Tennis & sports courts	Moss makes surfaces slick and degrades the coating	12 months
Gutters & roof areas	Overflow, water ingress, fire load	6–12 months
Graffiti	Attracts more graffiti the longer it stays	As required, promptly

The compliance side

Slip resistance and duty of care

Algae, lichen and oil films reduce the slip resistance of trafficable surfaces, and walkways, ramps and stair treads are where that matters most. A documented cleaning schedule is a simple, defensible maintenance record for common property, and it's usually cheaper than resurfacing a walkway that's been left to degrade.

Stormwater and runoff

In the ACT, allowing contaminated water to enter the stormwater system can breach environment protection requirements. On a residential driveway this is straightforward; on a car park, bin bay or food-service area, the runoff carries oil, grease and organic waste, and it needs to be managed. That means drain covers or bungs, containment, and recovering the wash water for proper disposal. It's worth asking any contractor directly how they intend to handle it.

Documentation and site access

For any commercial site, expect to see — and to ask for — a public liability certificate of currency, a SWMS covering the specific work, and height-safety competency where roofs, awnings or elevated access are involved. Most managing agents won't grant access without them.

Scheduling around people

The biggest practical constraint on commercial work isn't the cleaning, it's keeping people and vehicles away from wet, slippery surfaces while it happens. Typical approaches:

• Staged sections. Car parks and walkways cleaned in halves or bays so access is never fully lost.
• After-hours or early-morning work. Standard for retail and hospitality, so surfaces are dry before opening. In residential strata, ACT noise standards limit how early or late equipment can run, so timing needs to be agreed up front.
• Resident and tenant notice. Signage and advance notice reduce complaints far more effectively than anything else, particularly for cars that need to be moved.
• Wet-floor management. Barriers, cones and signage until surfaces are dry.

How commercial pricing works

Residential jobs are priced as a package. Commercial work is normally either per square metre for large open areas, or a fixed price per scheduled visit under an ongoing agreement. What moves the number:

• Area and condition. Rates drop as area grows; heavy oil and long-neglected surfaces push it back up.
• Access. Multi-level car parks, restricted height clearance, distance to a water source and power availability all add time.
• Out-of-hours work. Night and weekend scheduling carries a premium.
• Water management. Containment and recovery add cost, but they're not optional where runoff is contaminated.
• Frequency. A scheduled program is meaningfully cheaper per visit than ad-hoc call-outs, because maintained surfaces clean faster.

For smaller schemes and standalone sites, the residential ranges in our Canberra cost guide are a reasonable starting reference — but anything at genuine commercial scale should be quoted after a walk-through.

Getting the scope right

The most useful thing a manager can do before seeking quotes is define the scope precisely: which areas, what square metreage, what condition, what access constraints, what hours, and whether it's one-off or recurring. Quotes built on the same scope are comparable; quotes built on a vague "clean the common areas" aren't, and that's where disputes over scope creep begin.

FAQs

How much does commercial pressure cleaning cost?

Commercial work is usually priced per square metre for large areas, or as a fixed price per scheduled visit for ongoing contracts. Rates fall as area increases, and a recurring schedule prices better than one-off call-outs because each visit is quicker. The practical way to get a real figure is a site walk-through and a defined scope.

Who pays for pressure cleaning in a strata scheme?

Cleaning of common property — driveways, visitor parking, shared walkways, bin bays, lobbies and external common walls — is normally funded from the owners corporation's administrative fund. Anything inside a unit's exclusive-use area is generally the owner's responsibility. Check the scheme's rules and by-laws, as allocations vary.

Can pressure cleaning be done after hours?

Yes, and for retail, hospitality and car parks it usually should be. Working outside trading hours avoids pedestrian and vehicle conflict and lets surfaces dry before people are on them. Note that ACT noise standards restrict what can run late at night in residential areas, so overnight work in a residential scheme needs planning.

Is pressure cleaning a slip hazard management measure?

It's a real one. Algae, lichen, moss and oil films measurably reduce the slip resistance of a walkway, and a scheduled clean is straightforward, documentable evidence that a site is maintaining its trafficable surfaces. Many managers schedule common walkways specifically for this reason.

What about wastewater and stormwater rules?

In the ACT it is an offence to allow contaminated water to enter the stormwater system. Commercial work — especially car parks, bin bays and anywhere with oil or food waste — needs drain protection, containment and appropriate disposal of the recovered water. Ask any contractor how they manage runoff before they start.

Do you need insurance and documentation for commercial sites?

Yes. Expect a contractor to provide a certificate of currency for public liability, a SWMS for the work, and evidence of height-safety training where roof or elevated access is involved. Most managing agents and building owners require all three before site access is granted.
