Most facility managers who want to switch cleaning contractors delay the decision because they are not sure how to exit the current contract without creating a gap in service. The process is straightforward if the steps are taken in the right order.
Most commercial cleaning contracts include a notice period — typically 30 or 60 days — and sometimes an auto-renewal clause that locks in another term if notice is not given within a specific window. Pull the contract and note the exact notice requirement and the current term end date before making any other move. If you cannot find the contract, ask your current vendor for a copy.
The most common mistake in contractor transitions is giving notice first and then starting the quote process. That creates a clock. Instead, collect at least one written quote — including scope, price, crew assignment process and start date — before triggering the notice period on the existing contract. This gives you a confirmed replacement and a confirmed start date before the current vendor knows a transition is coming.
Written notice — email with a read receipt, or certified mail if the contract requires it — creates a documented record. Verbal notice creates a dispute about whether it was given. State the last service date explicitly. Keep a copy.
If the logistics allow it, structure the transition so the new contractor's first clean happens one week before the old contractor's last clean. This gives the new crew time to learn the space and identify anything the scope missed, while the old contractor is still under contract and responsible for service quality. The overlap cost is usually one extra week of cleaning — a reasonable insurance premium against a service gap.
Before the final clean by the outgoing contractor, do a walkthrough and document the state of the facility: floor condition, any outstanding items on the scope, supply inventory. This establishes a baseline for the incoming contractor and resolves any disputes about what condition the space was in at handoff.
A signed written scope, confirmed crew assignment, documented access procedure, certificate of insurance and a confirmed first clean date. If any of those are missing, the transition is not complete.
