Short answer

Ask how the scope is documented, who manages changes, how quality is checked, what happens when access changes, which tasks are periodic, and how additional work is approved.

Questions about the scope

Ask whether the proposal lists tasks by area and frequency. Confirm what is excluded, which periodic tasks cost extra, and how the scope changes when headcount or layout changes.

  • What happens every visit?
  • Which tasks rotate?
  • What is excluded?
  • Who approves added work?

Questions about scheduling and access

Discuss alarms, keys, lockboxes, building rules, elevators, parking, holidays, and contact procedures. A good proposal reflects real access constraints.

Questions about communication

Identify the main contact, the escalation path, and how issues are documented. Avoid relying on an undefined promise that someone will always be reachable.

Questions about quality

Ask how the written scope is reviewed, how missed items are reported, and how recurring issues lead to an adjustment in the plan.

Frequently asked questions

Should I choose the lowest office cleaning proposal?

Not without comparing scope, frequency, exclusions, and access assumptions. A lower total may represent less work.

Is a walkthrough necessary before hiring?

It is strongly useful because it aligns both sides on condition, access, materials, priorities, and schedule before pricing.
