Most commercial cleaning companies present well in a sales conversation. The gaps tend to show up later — in inconsistent service, unclear billing, or a different crew every few weeks.
Red Flags Before You Sign
No written scope of work. A verbal quote with no task list in writing leaves no accountability.
Unusually low pricing. Quotes significantly below market usually mean something is missing.
No proof of insurance. A legitimate cleaning company can produce a current certificate of insurance quickly. Hesitation is a sign they don't have it.
Vague answers about who cleans your space. If a provider can't tell you whether staff are employees or subcontractors, proceed carefully.
High-pressure sales tactics. Artificial urgency isn't a sign of a reputable business.
Red Flags During the Relationship
Constant staff turnover. A different crew every few weeks means no institutional knowledge of your space.
Ignored complaints. A provider that's slow to respond to service issues won't improve over time.
Skipped tasks you're paying for. Document any recurring gaps and raise them formally.
Reluctance to walk through the space with you. A transparent provider welcomes periodic walkthroughs.
