Eco Strata & Common Area Cleaning in Wollongong

Shared air, shared surfaces, shared accountability

Strata common areas are different from a private office. Lobbies, lifts, stairwells, carpark cores and shared amenities are used by every resident, of every age and health status, at every hour of the day. When conventional cleaning products are used in these enclosed, high-traffic spaces, the residues and fumes linger where people wait for lifts, carry groceries and let children pass through. That is precisely the environment where a lower-tox approach earns its place.

For an owners' corporation or building manager, the decision isn't only about a clean-looking foyer. It is about reducing complaints, protecting the people who do the work, and being able to demonstrate a defensible approach if a resident or committee asks what is being sprayed in their building. Low-tox cleaning answers all three.

Why residues matter more in common areas

The health evidence for cleaning products is stronger than most committees realise. Svanes et al. (2018), drawing on the European Community Respiratory Health Survey, found lung-function decline in regular cleaners comparable to around 20 pack-years of smoking. The AIHW attributes 9 to 15 per cent of adult-onset asthma to occupational exposure, with cleaning named as a high-risk occupation. In a strata setting, the exposure isn't limited to your contractor. Fumes and residues sit on handrails, lift buttons and lobby floors that residents touch and breathe around continuously.

Removing hazardous inputs at the source is elimination, which sits at the top of the WHS hierarchy of controls. It is the most effective control available, and it is the one that keeps working after the cleaner has left the building.

How our methods work

We replace the harshest conventional chemistry with methods proven to clean and disinfect without leaving hazardous residue:

• Electrolysed water (HOCl): made on site from water and a trace of salt, GECA-certified and TGA-listed. It cleans and disinfects, then reverts to salt water. Ideal for lobby surfaces, handrails and lift interiors where residents make contact.
• Stabilised aqueous ozone: an effective cleaner for floors and general surfaces that reverts to oxygen and water, leaving nothing behind.
• Dry steam: low-moisture thermal decontamination for grout, amenities and hard-to-reach detailing, useful in Wollongong's coastal humidity where moisture and mould pressure are real considerations.
• Colour-coded microfibre with disciplined dwell times: the unglamorous discipline that prevents cross-contamination between amenities, lifts and food-adjacent areas.

Where a task is disinfection-critical, we retain TGA-listed disinfectants and use them deliberately. We describe this honestly: no added synthetic chemicals and no hazardous residue on standard surfaces, never "chemical-free".

The compliance and ratings angle

Two things make this timely for Wollongong buildings. First, from 1 December 2026, enforceable Workplace Exposure Limits (WELs) replace the current WES across roughly 700 reviewed chemicals. Buildings that reduce hazardous inputs now are ahead of that curve rather than scrambling behind it.

Second, for mixed-use and higher-spec residential developments, GECA-certified products are deemed-to-satisfy for the Green Star Green Cleaning credit, WELL's Cleaning Products and Protocol feature targets hazardous-chemical reduction, and NABERS Indoor Environment tests VOCs and formaldehyde. If your building carries or aspires to any of these, our documentation supports what you need to report.

What a Wollongong strata program looks like

Every building is scoped individually, but a typical common-area program covers:

• Daily or several-times-weekly: lobby floors, lift interiors and buttons, entry glass, mail areas and high-touch points.
• Weekly: stairwells, shared corridors, amenity rooms and bin store areas.
• Periodic: hard-floor detailing, grout and tile decontamination, and moisture management in below-ground carpark cores where coastal humidity encourages mould.

Frequencies are matched to resident numbers, foot traffic and the building's amenity mix, then set out clearly so your committee knows exactly what is delivered. We work Australia-wide through an accredited partner network, so the Wollongong team follows the same methods and standards nationally.

Pricing without the premium myth

Low-tox does not mean high-cost. On standard common-area scopes we price at parity with conventional cleaning. A modest premium of 10 to 15 per cent applies only on health-critical or rating-critical sites where the extra rigour is genuinely warranted. The walkthrough and quote are free, so you can compare like for like before committing.

Book a free site walkthrough

The simplest way to understand what changes is to walk the building with us. We will assess your lobbies, lifts, stairwells and amenities, note the humidity and mould pressures specific to your site, and return a clear scope and quote your committee can review.
