Commercial cleaning is one of the most outsourced services in South African business, and one of the most prone to problems: staff who are not vetted, equipment that is inadequate, chemicals used incorrectly, and contracts that look reasonable until something goes wrong and the company is nowhere to be found. For many businesses, the cleaning crew has unsupervised access to the premises — including offices, server rooms, kitchens, and storerooms. Getting this decision wrong is not just inconvenient; it creates genuine security and liability exposure.
This guide focuses on the warning signs that appear before you sign a commercial cleaning contract — at the quoting stage, during reference checks, and in the contract terms. It applies to small business offices, retail spaces, medical practices, schools, and any premises where professional cleaning is contracted out.
Red Flags in the Quoting Process
A professional commercial cleaning company quotes after understanding your specific requirements: square metres of space, surfaces and materials, cleaning frequency, required times of service, and any specialist needs (medical-grade sanitisation, food-safe kitchen cleaning, high-floor window cleaning). A company that gives you a per-month price in a phone call without assessing the space is either guessing or bidding low to win the contract and then cutting the service.
Significantly below-market quotes are a consistent red flag in commercial cleaning. The main costs in cleaning are labour and consumables. If a company is substantially cheaper than competitors, they are either paying staff below minimum wage (creating liability risk for you under the Basic Conditions of Employment Act), using inferior chemicals (which may damage surfaces or be unsafe in food or medical environments), or planning to reduce cleaning frequency or time once the contract is signed.
Ask specifically what cleaning products will be used and whether the staff are trained to use them correctly. Incorrect dilution of industrial cleaning chemicals can damage flooring, surfaces, and fabrics — and exposure to improperly used chemicals creates a health risk for your staff. A professional company has documented cleaning protocols and knows the correct dilution ratios for every product they use.
Staff Vetting and Employment Practices
The cleaning staff will have access to your premises, often outside business hours. This makes vetting essential. Ask the company directly: do you conduct criminal background checks on all staff? How do you verify employee identity? What happens if a staff member is found to have a criminal record for theft or fraud after placement?
A company that vague-answers these questions, or says "we know all our staff personally," is not running a professional vetting process. Reputable commercial cleaning companies in South Africa conduct criminal background checks through registered background screening services, verify ID documents against the Home Affairs database, and maintain employment records for all staff.
Also ask about staff turnover. High turnover means a constant rotation of unfamiliar people in your premises — each of whom needs to be reveted and briefed on your specific requirements. It also signals poor employment conditions, which is itself a risk indicator for theft and carelessness.
Check whether the company complies with the Sectoral Determination for Private Security and Cleaning Services, which sets minimum wage rates for cleaning staff. If they are paying below sector minimum wage, they are in violation of South African labour law — and the liability for any resulting labour disputes can have implications for your business as the client.
Red Flags in the Contract Terms
Commercial cleaning contracts deserve careful reading. Common problematic terms include:
Blanket exclusion of liability. A clause stating the company accepts no liability for any loss, damage, or theft during cleaning operations. Under the CPA, this cannot exclude liability for negligence. If the clause is there, ask for it to be amended to "we accept no liability except where damage or loss results from negligence by our staff" — watch how they respond.
Long minimum contract terms with heavy cancellation penalties. Twelve-month contracts with a 3-month cancellation penalty are common in the industry. Understand what you are committing to before you sign, and whether the penalty is realistic given the service quality. Reputable companies with strong track records are often willing to negotiate shorter initial terms.
No service level agreement (SLA). A credible contract specifies what will be cleaned, how often, at what standard, and what the remedy is if the standard is not met. A contract that is simply "monthly fee for cleaning services" with no specifics is not enforceable when the service level drops.
Substitution of staff or equipment after signing. Some companies send a senior, experienced team for the initial assessment and first few sessions, then replace them with lower-skilled staff once the contract is locked in. Build in a right to be notified of permanent staff changes and to re-evaluate the contract if standards drop.
Reference Checks and Track Record
Always ask for two or three client references from businesses of a similar type to yours. A company that cleans office blocks may not be appropriate for a medical practice with infection control requirements. Ask for references specifically from clients in your sector.
When calling references, ask not just whether the cleaning is good, but how the company handled problems: what happened when something was damaged, when a staff member was identified as unreliable, or when the service standard slipped. A company's response to problems is more revealing than its performance when everything goes smoothly.
Check whether the company is registered with the Contract Cleaning Association of South Africa (CCSA). CCSA membership is voluntary but indicates a company that has committed to industry standards and ethics. Also verify that the company is registered as an employer with the relevant SETA (Services SETA for cleaning) — this is a legal requirement for training and skills development compliance.

- Ask for the cleaning protocol document showing which products are used and at what dilution
- Confirm that criminal background checks are conducted on all staff with access to your premises
