How Often Should an Apartment Complex Be Pressure Cleaned?

One of the most common questions strata managers and property managers ask is how often an apartment complex actually needs to be pressure cleaned. The honest answer is that it depends on several factors — but there are practical benchmarks that work for most properties in NSW.

The Baseline: Once a Year Is the Minimum

For most apartment complexes, a full exterior clean once per year is the minimum needed to stay on top of surface build-up. A single annual clean covers building facade washing, common area pathways, bin areas, car parks, and entry points. It keeps the property looking presentable, reduces the rate of surface degradation, and gives management a full photo record of the property's condition.

Once a year works reasonably well for smaller strata properties in lower-traffic areas with good natural drainage and minimal tree cover. For most apartment complexes in NSW, though, it's not enough on its own.

Why Most Properties Need More Frequent Cleaning

A few conditions push the required frequency up quickly:

• High foot traffic — busy common areas, narrow pathways, and shared entry points accumulate grime faster than low-traffic zones
• Tree cover and shade — areas that stay damp attract mould and algae growth within months of a clean
• Coastal locations — salt air accelerates surface staining and biological growth on building facades
• Bin areas and waste enclosures — these almost always need cleaning more frequently than the rest of the property, often every one to three months depending on tenant density
• Car parks and basement garages — oil, tyre rubber, and fluid staining builds up quickly in high-use areas

For most mid-sized apartment complexes, biannual cleaning — twice per year — covers the building exterior, common areas, and high-traffic surfaces well. Quarterly cleans are appropriate for larger complexes, high-density buildings, or properties where presentation is a priority for tenants or the owners corporation.

A Practical Schedule for Most NSW Apartment Buildings

A workable schedule for most apartment complexes looks like this:

• Building facade and common areas — every six to twelve months
• Entry areas, lobby surrounds, and pathways — every three to six months
• Car parks and driveways — every six months, or quarterly for high-use basement garages
• Bin pads and waste enclosures — every one to three months
• Pool surrounds and courtyards — every three to six months depending on use

A scheduled maintenance programme makes this easier to manage. Rather than raising a new work order each time, a maintenance plan locks in the frequency, keeps costs predictable, and ensures the property stays on a consistent cleaning cycle.

Signs Your Property Needs a Clean Sooner

Outside of a set schedule, these are the signals that indicate a clean should be booked:

• Visible green or black streaking on the building facade or walls
• Slippery walkways or entry areas after rain
• Tenant or resident complaints about appearance or odour
• Upcoming AGM, property inspection, or re-leasing activity
• Post-storm debris or organic staining on exterior surfaces

Getting the Right Programme in Place

The best way to work out the right schedule for your property is a site walkthrough. Surface types, drainage, shade, tenant density, and traffic patterns all affect how quickly a property builds up and how long a clean lasts. CleanHaven inspects each property before recommending a programme and provides a written scope and schedule that can be put to the body corporate for approval.
