Switching janitorial vendors in Metro Detroit does not have to mean a dirty building for two weeks. With the right sequence, you can move from one commercial cleaning company to another and keep your space client-ready every night. CJT Janitorial serves Wayne, Oakland, and Macomb counties and can walk facility managers through this process.
This guide covers the practical steps: reviewing your current contract, timing the overlap, handling keys and badges, inventorying supplies, and setting up inspections during the first month.
What should you check in your current cleaning contract before giving notice?
Pull your existing agreement and read the termination clause first. You need to know the required notice period, any auto-renewal deadlines, and whether equipment in your building belongs to you or the outgoing vendor. Missing an auto-renewal window can lock you in for another full term.
- Note the required notice period (commonly 30 to 90 days for commercial janitorial contracts).
- Mark any auto-renewal deadline on your calendar so you do not accidentally extend.
- Identify who owns the floor scrubbers, chemical dispensers, and other cleaning equipment on site.
- Confirm whether the contract includes early-termination language or fees.
How do you select a new vendor before canceling the old one?
Never cancel your current service before a replacement is confirmed with a start date in writing. A gap between vendors means your building goes uncleaned, and occupants notice quickly. Get walkthroughs from two or three local cleaning companies so you can compare written scopes and confirm each one covers your specific facility type.
- Request a walkthrough of your space from each candidate. A vendor who quotes without seeing the building is guessing.
- Compare written scopes of work side by side, not just monthly pricing.
- Ask for references from facilities similar to yours (office, medical, industrial, or apartment common areas).
- Confirm insurance documentation before signing.
How do you time the overlap so nothing gets missed?
Schedule one overlap night where both vendors have building access. The outgoing crew finishes its last shift, and the incoming crew starts the same week. This keeps your space covered and gives the new crew a chance to learn the building layout with a supervisor present from day one.
- Align the new vendor's start date with the outgoing vendor's final service date.
- Plan for the incoming crew to do a baseline deep clean on their first visit rather than jumping straight into the regular schedule.
- Notify tenants or occupants about the transition one to two weeks in advance so they know to expect a different crew.
What is the safest way to handle keys, badges, and alarm codes?
Security is the part of the transition that goes wrong most often. Collect all keys, fobs, and access badges from the outgoing crew on their final night. Reset alarm codes before the new vendor's first shift. Never give a new company the same code the old one used.
- Create a written inventory of every key, fob, and badge the outgoing vendor currently holds.
- Coordinate with your building's security or property management to deactivate old credentials and issue new ones.
- If your building uses a keyless entry system, schedule deactivation and reactivation several business days ahead.
- Confirm the new vendor's supervisor has tested their access before the first cleaning shift.
How do you inventory supplies and equipment without a gap?
Outgoing vendors sometimes strip the supply closet on their last night. Document the current inventory of paper goods, trash liners, soap, and chemicals at least one week before the transition date. Confirm who owns the equipment on site and make sure the incoming vendor has replacements staged if anything leaves with the old crew.
- Walk the supply closet with the outgoing vendor and photograph everything.
- Ask the outgoing vendor to leave a reasonable buffer of consumables for the bridge period.
- Confirm whether auto-scrubbers, burnishers, and vacuums belong to the vendor or your facility.
- Have the new vendor stage their own equipment and supplies before their first shift.
What should your first-month inspection cadence look like?
The transition is not done after the first night. Set up a structured inspection schedule during the first month so small misalignments get corrected early. At CJT Janitorial, we build a written task-and-frequency scope for every facility and give you a named point of contact to hold us accountable from day one.
- Week 1: Walk the building with the new vendor's point of contact. Document anything that needs adjusting.
- Week 2: Follow up on any items flagged during the first walk. Confirm the regular cleaning schedule is running as scoped.
- Week 3: Review supply usage and restroom stock levels.
- Week 4: Conduct a formal end-of-month review meeting. Assess the scope of work against actual results and agree on any adjustments.
Vendors who welcome early inspections are telling you something about how they operate. Vendors who push back on week-one walkthroughs are telling you something too.
How does CJT Janitorial help you switch vendors in Metro Detroit?
We start every new account with a free walkthrough of your space. We review square footage, traffic patterns, priority areas, and your current cleaning pain points. Then we put together a written scope that lists every task, frequency, and service window, along with a fixed monthly price.
You get a named point of contact for questions, scope changes, and service reviews. We handle offices, medical facilities, industrial and warehouse spaces, post-construction cleanups, floor and carpet care, day porter service, and apartment and condo common areas across Wayne, Oakland, and Macomb counties.
An insurance certificate is available on request. We coordinate the key handoff, supply staging, and overlap scheduling so your building stays clean through the entire transition.
Frequently asked questions
How long does a janitorial vendor switch take in Metro Detroit?
Most transitions take a few weeks from signed contract to first night of service. CJT Janitorial schedules a free walkthrough, builds a written scope, and confirms a start date that aligns with your outgoing vendor's final shift. Longer notice periods in your current contract may extend the timeline.
Can you switch cleaning companies without a gap in service?
Yes. The key is timing the overlap so the incoming vendor starts the same week the outgoing vendor finishes. CJT Janitorial coordinates the transition schedule, supply staging, and access logistics so your building stays clean through the handoff.
What should a new janitorial vendor's first week look like?
A good first week starts with a baseline deep clean to reset the building to a known standard. The vendor's supervisor should be on site during the first several shifts. CJT Janitorial walks the building with you after week one to document anything that needs adjusting.
Do I need to give my current cleaning company written notice?
Check your contract. Many commercial janitorial agreements require a month or more of written notice before cancellation. Send that notice via email or certified mail so you have a record. Do not wait until the notice period starts to begin evaluating replacement vendors.
What happens to keys and alarm codes when you switch janitorial vendors?
Collect all keys, fobs, and badges from the outgoing crew on their final service night. Reset alarm codes before the new vendor's first shift. CJT Janitorial works with your building security to coordinate badge issuance and access testing ahead of our first cleaning night.
