Switching Janitorial Vendors with Minimal Disruption
To switch janitorial vendors with minimal disruption to operations, plan the change from your contract's notice deadline rather than its expiration date, settle exit terms before you tell the incumbent, and decide how the current crew will be handled. Require a written transition plan from the new vendor before award. Once service starts, run a joint inspection in the first month to set a baseline, put escalation paths in writing, and keep a regular review cadence so quality holds after the handoff.
The switch itself is where the risk sits. The building still has to be cleaned every night, including the night the contract changes hands, and the new vendor is learning the building while production, classes or public services carry on around it. Much of that risk can be seen in advance: an exit timed off the wrong date, no plan for the people already in the building, or a start with no baseline to measure against. This guide goes through each stage, from giving notice to the first quarterly review.

Further down: common ways a transition goes wrong and where McLemore fits.
When should you start planning a janitorial vendor switch?
Start from the notice date, not the end date. Many janitorial contracts renew automatically for another term unless one side gives written notice by a set deadline. Notice windows commonly fall 60 to 90 days before expiration, and some contracts require more, so check what yours says. Miss that window and the contract can roll over for a full term, sometimes with a price escalation already built in.
Pull the contract and find three things before anything else:
- The notice deadline: the last date written non-renewal notice can be given, and how it has to be delivered
- Termination for convenience: whether you can exit mid-term, with how much notice, and at what cost
- Termination for cause: what counts as cause, and whether the vendor gets a cure period first
Then work backward from the notice deadline. If you want to evaluate alternatives properly, with site walks, bids, references and internal approvals, we recommend starting four to six months before that date. That leaves room to finish the evaluation before the window closes, and our guide on how to run the buying process lays out each step in order.
What should you settle before you tell the incumbent?
Before the incumbent hears you are leaving, know what you own and what they own. Equipment, consumables stock, keys, badges, alarm codes, chemical inventory and any documents describing how your building is cleaned should all be listed, with a handover date for each.
Check for costs that come due at exit: equipment amortization written into the monthly rate, minimum-term penalties, or supplies you are required to buy back. It is better to find those now than to argue about them on an invoice after you have left.
Then plan for the last 30 days. An incumbent that has lost the account still has to perform to the end of the contract. Keep inspecting through the notice period, and document what you find.
What happens to the incumbent crew?
The people cleaning your building now know things that are written down nowhere: which door sticks, which manager wants their office left alone, where the roof leaks when it rains. Some of them are likely good at the job, and your occupants may know them by name.
Ask every bidder how they handle incumbent staff. Good answers include interviewing the current crew, rehiring those who pass the new vendor's background check and meet its standards, and bringing them on as the new vendor's employees. A vendor that plans to bring in an entirely new crew should explain why, and how it will learn the building in time. For one example, our distribution center takeover case study describes a transition run quietly during peak season, in which 5 of the 7 incumbent staff were retained.
Do not promise the crew anything yourself. The hiring decision and the employment relationship belong to the new vendor.
What does a 90-day transition timeline look like?
A well-run changeover moves in phases. The table below is an illustrative sequence, not a standard. The dates shift with the size and complexity of the facility, but the order tends to hold.
| Phase | Illustrative timing | What should happen | What you should see |
| Pre-start | 2 to 4 weeks before start | Site walk with the new supervisor, area-by-area documentation, crew hiring and background checks, badging, site-specific training, supply and equipment staging | A written transition plan with names and dates |
| First week | Days 1 to 7 | Crew on site under direct supervision, daily check-ins with your facility lead, punch list opened | A daily log and a single point of contact |
| First month | Days 8 to 30 | Daily check-ins continue, first formal inspection, punch list worked down | Inspection results and a shrinking punch list |
| Stabilization | Days 31 to 60 | Check-ins move to weekly, periodic work (floor care, high dusting) scheduled | A 30-day review with trends, not anecdotes |
| Steady state | Days 61 to 90 | Inspection cadence settles, reporting format agreed | A 90-day review that sets the baseline for the first QBR |
At McLemore this sequence is a documented process: a pre-start walkthrough by our operations team, area-by-area documentation, facility-specific crew training, the account supervisor on site through the first week, daily check-ins for the first 30 days, and a structured 30-day review. Issues raised in the first weeks are addressed within 24 hours. Our standard is minimal disruption to your operation. Whoever you choose, ask to see something equally specific, on paper, before award. We covered the kickoff itself in more detail in how to kick off a vendor transition.
How should you run the first inspection?
The first formal inspection matters because it is the first measurement, and later conversations about quality get measured against it.
Run it jointly, with your facility lead and the vendor's supervisor walking the same areas with the same checklist. Agree on how it is scored before anyone picks up a clipboard: which areas, which items, what counts as a pass. Keep the results. Six months from now, "it's gotten worse" is an opinion. A recorded drop, for example restroom scores falling from 94 to 81 (a hypothetical figure), is something the vendor has to answer.
Service can drift after the first few months, once attention moves elsewhere and the transition is treated as finished. We wrote about that pattern in why janitorial contracts start strong and fall apart after 90 days. An inspection cadence set in the first month gives both sides a way to see drift early and correct it.
Who do you call when something goes wrong?
Before the first night of service, you should know who to call for each type of problem, and what response to expect. The paths below are examples; agree on the actual paths with your vendor.
- A routine miss, like a skipped trash run or a restroom out of supplies, goes to the site supervisor. Example expectation: fixed that shift or the next.
- A repeated miss, for example the same miss three times in two weeks, goes to the account or area manager. Example expectation: a corrective plan in writing.
- Anything urgent, such as a spill near production, flooding or a security concern, goes to a 24/7 number.
- A pattern of misses, or a supervisor who is not working out, goes to a named executive at the vendor.
Put names and numbers in an escalation sheet, and update it whenever someone changes roles. Ask for the sheet before start. If a vendor cannot produce one yet, ask who will handle each type of escalation and when the sheet will be ready.
What should a quarterly business review cover?
For larger accounts, the quarterly business review is where you and the vendor look at the whole picture together. A useful QBR covers inspection scores by area and trend, service completion rates, the punch list and complaint log, staffing stability including supervisor changes, safety incidents, and anything coming up on your side such as a shutdown, an event, an expansion or a budget change.
It should run from data both sides saw in advance. If you are seeing your scores for the first time in the QBR, the reporting between reviews needs fixing.
What should you do when service slips?
Service can slip at some point, even with a good vendor. What you can judge is how the vendor responds.
When you raise an issue, a good vendor acknowledges it, finds the cause (staffing, training, supervision or scope), fixes it, and tells you what it changed. The warning signs look different: explanations that shift, fixes that last a week, and more of your team's time spent chasing the vendor. If you recognize that last one, we listed the signs you're managing your janitorial vendor instead of the other way around.
If the pattern persists, go back to the contract. Document each miss against the inspection baseline, give written notice under the cure provision, and keep the record. A documented cure process puts you in a stronger position if you later need to terminate for cause; have your legal or procurement team confirm the steps your contract requires.
What are the common ways a transition goes wrong?
- Timing the exit off the expiration date. By then the notice window may have closed and the contract renewed.
- Starting without a baseline. With no agreed reference point, quality conversations can turn into arguments.
- No plan for the incumbent crew. What the old crew knew about the building can leave with them.
- Treating day 30 as the finish line. Check-ins stop, supervision thins out, and service can drift in the months that follow.
- Escalation paths nobody wrote down. The first real problem turns into a search for the right phone number.
Where McLemore fits
McLemore has run janitorial programs for more than 50 years and retains 96 percent of its clients year over year. Our transitions follow a documented process, and the first 30 days include daily check-ins with your team. After that, sites with 10 or more full-time staff have a dedicated on-site supervisor, and smaller sites are overseen by a route or area manager. The standard we hold the transition to is minimal disruption: the switch should touch your operation as little as possible.
Guides on buying, budgeting, staffing and managing custodial services, sorted by role and facility type, are collected in the Facility Services Resource Center.
If you are weighing a change and want to know what a transition would actually involve at your facility, we will walk the building with you and lay out the plan before you commit to anything. Reach the sales team at sales@mbminc.com or (713) 528-7775.
