How to Switch Custodial Contractors Without Disrupting Your Campus

By Keith Mowen, CEO, Contract Service Solutions, LLC · Published November 2026

Short answer: A custodial contractor change goes well when the transition is planned before award, not after. Require a written 30, 60 and 90-day transition plan in the RFP, settle the incumbent workforce question early, run a baseline inspection before the new contractor starts, and measure the first 90 days against the same standard you'll use for the life of the contract. Most transitions that go badly fail in the first two weeks, on keys, badges, staffing and communication, not on cleaning.

Why custodial transitions go wrong

Changing contractors is one of the few times a facilities leader can reset a custodial program. It is also when the program is most likely to slip. The new contractor is learning your buildings, the outgoing contractor has little reason to help, and the people doing the work are wondering whether they still have jobs.

The common failure points are predictable:

Every one of these can be planned for before the first shift.

Plan the transition in the RFP, not after award

The best time to fix a transition is when you write the solicitation. Ask every bidder for a dated transition plan as part of the proposal, and score it. A plan that says "seamless transition" without dates, names and milestones is a warning, not a plan.

A strong plan answers:

Settle the incumbent workforce question early

The custodians already working in your buildings know where everything is, which spaces matter most and which problems keep coming back. Losing all of that knowledge at once is the single biggest risk in a transition.

Decide early what you expect. Many institutions ask the new contractor to interview and offer positions to qualified incumbent staff, and some public contracts and collective bargaining agreements require it. Whatever your rules are, put them in the RFP so every bidder prices the same assumption, and communicate them to the current staff before rumors fill the gap.

Before day one: the first 30 days

The first month is about readiness, not perfection. By the start date you want:

Days 31 to 60: full service, measured

By the second month, the new contractor should be delivering the full contracted scope at the contracted levels. This is when scored inspections start to matter. Compare them with the baseline. Track service requests, how fast they are answered and how fast they are closed.

If you required a work-order and inspection system you can log into, this is when it earns its keep. You shouldn't have to ask how the transition is going. You should be able to see it.

Days 61 to 90: adjust to how your buildings are really used

Once the basics are steady, a good contractor uses what it has learned to adjust. Some spaces need more attention than the old schedule gave them, and some need less. Expect a short review at day 90 that shows what was found, what changed and what the scores are doing.

Frequently asked questions

How long does it take to transition to a new custodial contractor?

Plan for about 90 days from the start date to a fully settled program, with the first 30 days focused on readiness. Hiring, background checks, training and access should be underway before the start date.

Should the new contractor hire the current custodial staff?

Often, yes. Incumbent staff know your buildings, and keeping qualified people reduces disruption. Some public contracts and labor agreements require offering positions to incumbent staff. State your expectation in the RFP so every bidder prices the same assumption.

What should a custodial transition plan include?

A transition lead, a dated 30, 60 and 90-day timeline, the approach to incumbent staff, hiring and training dates, equipment and supply readiness, key and badge control, a baseline inspection, and a communication plan for building occupants.

How do I know if the transition is working?

Compare scored inspections with the baseline, and track service requests, response times, staffing levels and occupant feedback through the first 90 days.

What is a baseline inspection?

A scored inspection of your buildings against your APPA levels, done before or at the start of the new contract, that both sides agree on. It is the starting point every later result is measured against.
