How to Interview Commercial Cleaning Companies

Published by the ABR team · Updated October 2026

Key takeaways
  • Use the same questions and the same scorecard for every company.
  • Ask for documents, not just answers: insurance, a sample checklist and references.
  • Decide on scope clarity, quality control and communication, not on the best presentation.

Think of this as a hiring interview. You are hiring a team to care for your building, so a consistent process pays off.

1. Prepare a scorecard

2. Ask the same questions

Keep a short list and ask in the same order. Good starting points are in questions to ask before hiring and during a consultation.

3. Request documents

4. Pay attention to how they listen

5. Check references

Ask each reference:

6. Compare and decide

Sit down with your scorecards. Look at where the companies differ on the factors you care about most. If the top two are close, ask both a final question or two.

Tip: Involve whoever will work with the vendor day to day, such as the office manager. They will notice details you may not.

Finish with the vendor verification checklist.
