10 Questions to Ask Before Hiring an Office Cleaner

The 10 questions that separate a reliable Adelaide office cleaner from a risky one cover insurance, security clearance, staff retention, cover for sick days, the remedy for a missed clean, references, equipment and products, scope, contract term, and communication. A professional answers each one clearly and specifically. Vague or evasive answers are the reddest flag there is, and they tell you more than any quote.

The 10 questions

1. Are you fully insured, and can I see the certificate?

You want current public liability cover, typically $10 million to $20 million for commercial work. Ask for the certificate of currency and check the expiry date. Uninsured cleaning turns any accident on your premises into your liability.

2. Are your staff security-cleared and background-checked?

Because most Adelaide offices are cleaned after hours, cleaners have keys and unsupervised access. You want cleared, directly employed staff, and police checks where the site is sensitive.

3. How long has the crew that would clean my site been with you?

Staff retention is the best single predictor of a stable standard. Low churn means the same people learn your building. Frequent new faces mean the standard will drift.

4. What happens when a cleaner is off sick?

A real company has trained backup and your clean still happens. A sole operator with no cover means a missed clean every time they are unwell or on leave.

5. What is your remedy if a clean is missed or below standard?

The professional answer is a prompt re-clean or a credit, in writing. No remedy means you have no leverage when something goes wrong, which it eventually will.

6. Can you give me 2 or 3 current Adelaide references?

Ask for references from sites of a similar type and size to yours, and actually call one. A cleaner proud of their work hands these over without hesitation.

7. What equipment and products do you use?

You want commercial-grade equipment, colour-coded cloths to avoid cross-contamination between bathrooms and kitchens, and safe, compliant products. Ask whether green or low-tox options are available if that matters to your team.

8. Exactly what is included in each clean?

Get the scope in writing: daily tasks, rotational tasks, and add-ons. This is the document you hold the contractor to, so it needs to be specific, not a generic list.

9. What is the contract term and notice period?

Understand the minimum term, how price reviews work, and how much notice ends the agreement. A confident cleaner does not need to lock you into a long, hard-to-exit contract to keep you.

10. Who do I contact, and how fast do you respond?

You want a named point of contact and a clear response time. Cleaning problems are usually small and easily fixed, but only if someone answers when you raise them.

How to read the answers

The content of the answer matters, but so does the manner. A professional who runs a tight Adelaide operation answers these confidently, with specifics: a name, a number, a written document, a certificate. Hesitation, deflection, or a promise to send something later that never arrives all point the same way.

• Specific, confident answers with documents to back them up signal a professional.
• Vague answers, no paperwork, or defensiveness are consistent red flags.
• Any refusal to show the insurance certificate should end the conversation.

Why asking upfront saves you later

Nearly every cleaning-contract problem traces back to a question that was never asked. No sick-day cover becomes a missed clean before a client visit. No written remedy becomes a standoff over a floor that was skipped. No scope becomes an argument about whether internal glass was ever included. Asking these 10 questions before you sign prevents the most common disputes entirely.

Turning the answers into a shortlist

Ask all 10 questions of every cleaner you are considering, and treat the first 5 (insurance, clearance, retention, sick-day cover, and remedy) as pass-or-fail. A contractor who stumbles on any of those comes off the list regardless of price. Then use the remaining questions on references, equipment, scope, term, and communication to separate the cleaners who cleared the bar, because that is where the difference between a good contractor and a merely acceptable one shows up.
