This case study is based on a real Adelaide client. The company name is not shared at their request, but the details are accurate. They are a professional services firm based in Norwood with 18 staff, operating from a single-floor office of approximately 220 square meters.
The Situation Before We Started
When they first contacted us, this Adelaide firm was running on a weekly clean from a solo operator they had used for about two years. The cleaner came on Friday mornings, worked through the office while staff were present, and charged a flat fee that had not changed since the arrangement started.
On the surface, it seemed to be working. The office looked presentable enough. The floors were vacuumed. The desks were wiped. Nobody had complained directly.
What the business owner noticed when she looked more carefully was a pattern she had not connected to the cleaning. Between May and August each year, the team ran about 30 percent higher sick day rates than the rest of the year. She had put it down to winter illness. Which is partly right. But she had also never asked whether the office environment was making the transmission of that illness easier than it needed to be.
What We Found When We Assessed the Site
When we visited the site, the visible cleaning was adequate. The problem was in the surfaces that routine weekly cleaning was not reaching consistently.
The bathroom exhaust fan covers had not been removed and cleaned in a long time. The kitchen tap handles showed heavy residue. The door handles throughout the office had not been part of the regular scope. High-touch surfaces including light switches and the shared printer and coffee machine had no sanitizing component in the existing routine at all.
The kitchen was cleaned weekly, meaning it received full attention once in five working days. With 18 staff using it daily, that left four days between each clean where benches, tap handles and shared appliance surfaces accumulated contact contamination without being addressed.
The cleaner was not doing a bad job. They were doing exactly what they had been asked to do, on a scope and frequency that was not matched to how the space was actually being used.
What We Changed
We moved the firm from a weekly single visit to a three times per week schedule. Monday, Wednesday, Friday evenings, after the office closed.
The scope change was specific. Every visit included full sanitising of all bathroom tap handles, door handles throughout the office, light switches, and the shared kitchen surfaces and appliance handles. The kitchen received attention three times per week instead of once. Bathroom exhaust fans were added to the fortnightly rotation.
The cost increase from the previous arrangement was around $280 per month. The business owner approved it after we walked her through the specific changes to scope and the reasoning behind each one.
We also added carpet cleaning on a quarterly cycle, which addressed the traffic lane buildup in the corridor and the entry that had not been extracted since the office was fitted out.
What Happened Over the Following Six Months
Three months in, the office manager mentioned that the kitchen complaints had stopped. There had been a recurring issue where staff raised the state of the kitchen in team meetings. That stopped in the first month. She assumed the timing was coincidental until it had not come back after three months.
At the six-month mark, we asked for a formal review of how the service was working. During that conversation, the business owner mentioned something she had not expected to notice: the sick day rate over June and July, which had historically been the worst two months for absences, was down compared to the same period the previous year.
She was careful about attributing it entirely to the cleaning, which is the right instinct. There were other variables. But she noted that nothing else significant had changed in the business during that period. Same team, same workload, same office. The main operational change was the cleaning frequency and scope.
The sick day reduction across those two months represented approximately 11 fewer sick days across the team compared to the year before. At an average loaded staff cost of around $450 per day, that is approximately $4,950 in recovered productivity. Against a cleaning cost increase of $280 per month, the financial case is straightforward.
What This Reflects More Broadly
This case study reflects a pattern we see regularly across Adelaide offices. The problem is rarely a bad cleaner. It is a mismatch between cleaning frequency and scope, and how the space is actually being used.
According to Safe Work Australia, maintaining sanitary facilities and clean work areas is part of an employer’s ongoing duty of care. The practical application of that obligation is a cleaning schedule and scope that matches the actual use of the space, not the minimum that keeps the floor looking presentable.
An office with 18 staff sharing a kitchen, bathrooms, a corridor, and shared equipment is not the same cleaning environment as a four-person office where two people work from home three days a week. Treating them the same way produces the results this Adelaide firm was experiencing before they called us.
What Changed for This Business Beyond the Numbers
Beyond the sick day rate, the business owner noted two other changes that she felt were directly connected.
The first was staff feedback. In a team survey run about four months after the change, several staff members mentioned the kitchen and bathroom cleanliness specifically as something that had improved. Nobody had been asked about cleaning. They raised it unprompted in response to a general question about the office environment.
The second was her own experience of the space on Monday mornings. Before, she had noticed the kitchen and bathroom on Monday with a sense of mild frustration, particularly after a busy Friday. After the schedule change, Monday mornings felt different. That is a small thing. But it is also the thing that shapes how people feel about coming into work, which is not a small thing at all.
How This Applies to Your Adelaide Office
If your office has more than ten staff sharing bathrooms and a kitchen, and your current cleaning happens once a week, the scenario above probably sounds familiar.
The solution is not always expensive. In this case, moving from one visit to three visits per week, with a more specific scope, cost less than $70 per week more than the previous arrangement.
