How to Choose a Commercial Cleaning Company: 9 Questions to Ask

Switching janitorial vendors is disruptive, so the goal is to choose well the first time. The difference between a partner you keep for years and one you replace in six months usually comes down to the questions you ask before signing.

The 9 questions that matter

1. 1Will I have a dedicated, consistent crew — or a rotating cast?
2. 2Are your workers background-checked and insured?
3. 3Who supervises quality, and how do you handle complaints?
4. 4Is the scope of work documented in writing?
5. 5Do you offer after-hours and emergency service?
6. 6What products do you use, and do you have green options?
7. 7Can you scale across multiple locations if we grow?
8. 8How quickly can you provide a quote, and is it walkthrough-based?
9. 9Can you share references in my industry?

Red flags to walk away from

• A quote with no documented scope of work.
• No supervisor or quality-check process.
• Unwillingness to confirm insurance or background checks.
• A price dramatically below every other bid.
• High crew turnover or no dedicated team.

Why the dedicated-crew question is the most important

Consistency is the entire game in commercial cleaning. A dedicated crew learns your building, your standards, and your quirks — and that institutional knowledge is what keeps quality high month after month. Vendors who rotate anonymous crews can’t deliver it.
