Switching commercial cleaning companies without a gap in service

Switching commercial cleaning companies without a gap comes down to order of operations. Sign the new vendor first, give notice second, and use the notice period to hand over everything the old crew holds, including what they know but never wrote down.

The plan here runs day by day, with a handover checklist to copy and the step that prevents most first-month complaints: capturing the building knowledge that walks out the door with the old crew.

Before you give notice

Do not give notice until the new contract is signed and you have its certificate of insurance. Notice given first can leave you with a final night and no first night.

Do these four things while the current vendor is still unaware:

1. Read the termination clause. Find the notice period, how notice must be delivered, any auto-renewal date, and any fee for early exit.
2. Pick the new vendor. Walkthroughs and written quotes from two or three companies. Our guide to hiring a commercial cleaning company covers what to ask, and a short janitorial RFP makes the bids comparable.
3. Sign with a start date. Set it for the night after the old vendor's final night.
4. Collect the certificate of insurance. Check it against what your lease or risk team requires.

If the current contract is weak on exit terms, fix that in the new one. Our janitorial contract checklist lists the handover clauses to require.

The 30-day transition plan

A typical switch runs on a 30-day notice period. Here is how to use it.

Expect the outgoing crew's effort to slip in the final two weeks. Keep morning walks going and log misses with dates and photos, in case you need to dispute a final invoice.

Building knowledge: the handover nobody writes down

Every night crew carries knowledge that is not in the scope. Which door alarm trips if you prop it. Which tenant wants the suite door locked behind the crew. Which restroom drain backs up. Where the spare paper is. That the CEO works late on Thursdays.

When the crew changes, that knowledge leaves with them, and the first two weeks of complaints usually trace back to it. It is the cheapest part of the switch to fix.

Ask the current supervisor for a short interview before the final weeks, or walk the building yourself at night and write it down. Capture:

• Alarm zones, arming steps, and doors that must never be propped.
• Rooms that stay locked, and rooms the crew must lock behind them.
• Tenant or department preferences: no cleaning during a late meeting, desks left untouched, confidential bins.
• Recurring problem spots: a drain, a leak, a carpet stain that keeps coming back.
• Supply closet locations and the paper and soap brands in each dispenser.
• Trash and recycling routes, compactor or dumpster schedules, and pickup days.
• Periodic work history: when floors were last stripped and refinished, when carpet was last extracted.

Hand the sheet to the new account manager at the walkthrough. It becomes part of the site's work instructions.

Keys, supplies, and baseline photos

Before you give notice, list every key, fob, and alarm code the old vendor holds. Collect them on the final night, deactivate the old codes and fobs the next morning, and rekey any lock whose keys do not all come back. Give the new crew individual codes so activity traces to a person.

Inventory the janitor's closets too, and decide who owns what. Paper, liners, and soap you paid for stay. The old vendor's machines and chemicals leave by an agreed date. If the new vendor supplies paper, check that it fits your dispensers, since many take one brand only.

Then take dated photos of floors, restrooms, and any damage in the last week. A worn floor finish or a stained carpet belongs to the old contract, and the new vendor's floor work starts from a clear baseline.

Timing the start, and whether to overlap

Pick the start date with your building's calendar open next to the notice period:

• Avoid the week of a big event, a tenant move-in, an audit, or a board meeting. The new crew needs a normal week first.
• Watch the old vendor's floor work. A strip and refinish scheduled after the final night will not happen. Get it done before the final night, or plan it with the new vendor.
• Use slow periods where you have them: summer for schools, the weeks after the holiday rush for stores.
• Plan periodic work for month two, once the new crew knows the building.

A full overlap, with both vendors cleaning for a week, means paying twice and is rarely needed. These get the same benefit for less:

• A crew walk before day one. The new crew lead walks the building at night a few days before the start and finds the switches, closets, and alarm panel before cleaning around them.
• A heavier first week. Ask for an extra person or a supervisor on site for the first few nights.
• A phased start on large sites. Switch one building or floor group at a time, a week apart.

If you have daytime porter coverage, keep the porter shift continuous across the switch. Restrooms and lobbies show a gap first.

Send tenants or staff a short note a week ahead: the date, that a new crew will be in at night, and who to contact with problems (you or the account manager, not the night crew). In multi-tenant buildings, add any change to service nights or day porter hours.

Handover checklist to copy

The list for your transition file:

• New contract signed, start date set, certificate of insurance received
• Written notice sent per contract, final service date confirmed
• Building knowledge sheet completed
• New vendor walkthrough done, scope reviewed room by room
• Key, fob, and code list made; all returned on final night
• Old codes and fobs deactivated; new individual codes issued
• Closet inventory done; vendor equipment removed by agreed date
• Baseline photos taken and filed
• Tenant or staff notice sent with contact for problems
• Day 7 inspection booked; day 30 scope review booked

Start the switch with a walkthrough

Book our walkthrough before you send notice, so the written quote and our certificate of insurance are both in hand on day -30. Tell us your notice period and the old vendor's final night, and we set the first night to follow it. Your building knowledge sheet goes to your dedicated account manager, and the new crew holding your keys is background-checked.
