When a Facilities Contractor Should Stop Using a Staffing Agency

A facilities contractor should start moving off staffing agencies once its hiring is high-volume and predictable enough that agency markups exceed the cost of a sourcing capability, which for most firms happens sooner than they think.

Signal 1: predictable, recurring roles

If you are paying agency fees for the same roles month after month, you are renting something you could own. Predictability is the clearest signal to insource.

Signal 2: agency spend is a real line item

When agency markups add up to more than a sourcing tool would cost, the maths has already tipped. Many contractors never actually run this comparison.

Signal 3: you want continuity

If you are frustrated by never getting the same workers, or by quality you cannot control, that is agencies' structural limit, not a fixable complaint.

How to transition safely

Do not cut the agency off cold. Build in-house sourcing for your easiest roles first, prove the fill rate holds, then expand. Keep the agency for genuine surges.

A real-world example

A contractor that had used the same agency for years finally compared the annual markup to a sourcing subscription, found it was overpaying heavily on routine roles, and transitioned in stages without a single unfilled shift.
