How to Switch Commercial Cleaning
Companies Without a Gap in Service

Most businesses that are unhappy with their cleaning company don’t switch. Not because the service is acceptable, but because switching feels like more trouble than tolerating it. There’s a contract to read, keys to recover, a new crew to explain the building to, and the worry of a week where nobody cleans at all.

So the trash keeps getting missed on Thursdays, the restrooms keep running out of towels, and someone on staff keeps quietly doing the work the vendor is being paid for.

Changing cleaning companies is genuinely straightforward when it’s planned. Done in the right order, the old vendor’s last night and the new vendor’s first night can be back to back, with no gap and very little effort on your side. This is the order.

How to Switch Commercial Cleaning Companies Without a Gap in Service

1. Confirm It's Time — and Whether the Problem Is Fixable

Before starting a switch, it’s worth being honest about whether the relationship can be repaired. Sometimes one direct conversation fixes it.

Common patterns that usually can be fixed:

  • A specific task being missed that was never clearly in the scope
  • A new crew member who hasn’t been trained on your building
  • A communication breakdown with a single point of contact

Patterns that usually signal it’s time to move on:

  • The same issues recurring after they’ve been raised more than once
  • Missed visits, or crews arriving and leaving noticeably early
  • Nobody answering or returning calls
  • Staff doing cleaning work themselves to cover gaps
  • Security concerns — unlocked doors, alarms not set, unfamiliar people with keys
  • Declining standards with no explanation
  • Surprise charges or price increases outside the agreement

If you’ve raised the problem clearly, in writing, and it hasn’t changed, you have your answer. Documenting that conversation is also useful if the contract requires cause for termination.

2. Read Your Current Contract First

The single most important step, and the one most often skipped. Find the agreement and check:

  • Notice period — typically 30 to 60 days’ written notice
  • Term and renewal date — especially whether it auto-renews, and whether there’s a narrow cancellation window
  • Termination for cause — whether poor performance allows an earlier exit, and whether a cure period applies
  • Early termination terms — any fee or penalty
  • How notice must be given — email, certified letter, a specific address
  • Equipment and supplies — what belongs to the vendor, and what belongs to you

Month-to-month agreements are simple: give the required notice and set the end date. Longer contracts need more care, particularly around the renewal window. If you find you’re inside a long term with no performance exit, that’s worth remembering for the next contract — our guide to what a cleaning contract should include covers what to look for.

3. Line Up the New Vendor Before Giving Notice

The order matters. Choose the replacement first, then give notice. Doing it the other way round is how buildings end up with a gap.

  • Schedule walkthroughs with two or three candidates
  • Get a written scope of work from each, built from your actual building
  • Compare scopes line by line, not just monthly totals
  • Check insurance, workers’ compensation, and background screening
  • Agree a start date that lines up with the end of your notice period
  • Confirm the new vendor can start on that exact date

A walkthrough is also the moment to fix whatever went wrong last time. If the old vendor missed things because they were never written down, write them down now. Our guide on how to choose a commercial cleaning company covers vendor evaluation in more detail.

4. Plan the Handover Date

The goal is for the outgoing vendor’s last service and the incoming vendor’s first service to fall on consecutive nights.

A clean timeline looks like this:

WhenStep
Week 1Walkthroughs and written quotes from new vendors
Week 2Choose the new vendor, agree the start date, sign
Week 2Give written notice to the current vendor, stating the final service date
Final 2 weeksNew vendor confirms supplies, access, and scope details
Last nightOutgoing vendor’s final service; keys and codes returned
Next nightNew vendor’s first service
Week 1 of new serviceJoint walkthrough and adjustments
Day 30Formal review against the scope

Where the notice period is longer than the time you need, you can still line things up — the new vendor simply starts on the day the old agreement ends.

If the current vendor has already stopped showing up, the timeline compresses. Most established cleaning companies can start within days for a building that genuinely has no service, and the initial visit is usually a deeper catch-up clean.

5. End the Old Relationship Professionally

A clean exit protects you, and it’s simply good practice in a market where businesses know each other.

  • Give notice in writing, in the way the contract requires
  • State the final service date clearly
  • Keep it brief and factual — there’s no need to list every grievance
  • Arrange the return of keys, fobs, and access cards on or before the final day
  • Confirm what equipment and supplies belong to them and when they’ll collect it
  • Request a final invoice and confirm nothing is owed beyond the agreed term

Most cleaning companies handle a professional termination professionally. Staying courteous also makes the key return and final invoice go smoothly.

6. Secure Your Building During the Changeover

This is the step with real risk attached, and the one most often handled loosely.

  • Recover every key and fob issued to the outgoing vendor, and count them against your records
  • Change alarm codes assigned to the outgoing vendor on their last day
  • Deactivate access cards and remove any vendor accounts from your access system
  • Re-key or change locks if keys can’t all be accounted for, or if you have any security concern
  • Update your alarm company with the new vendor’s authorised contacts
  • Issue new access to the incoming vendor under a documented process

If you don’t currently know how many keys your cleaning company holds, that’s worth fixing now regardless of whether you switch. Key control belongs in writing, as covered in our guide for property managers.

7. Supplies, Equipment, and Consumables

Small details that cause friction on day one if nobody checks:

  • Consumables — whether the new contract includes soap, paper products, and liners, or whether you supply them. If the old vendor supplied them, expect the dispensers to be near-empty on their last day.
  • Dispensers — some vendors install their own branded soap and towel dispensers and remove them when they leave. Check whether yours are owned or loaned.
  • Supply closet — clear out the old vendor’s chemicals and equipment, and confirm the new vendor has storage space.
  • Chemicals — anything left behind should be identified before being used or discarded.

The dispenser question catches more businesses than any other. Ask it before the last night, not on the first morning.

8. The First 30 Days With the New Vendor

The start of a new relationship sets the standard for the rest of it.

  • First-week walkthrough — walk the building together after the first few services and point out anything missed or done differently than expected
  • A single point of contact on both sides, so feedback goes to one person
  • Written notes, not just conversations — a short email after the walkthrough keeps everyone aligned
  • Adjust the scope where needed — the first weeks often reveal tasks that need adding, moving, or changing in frequency
  • A 30-day review — a structured check against the written scope
  • Expect a catch-up clean — if the previous service had slipped, the first visits usually involve more work than routine ones

A good vendor welcomes the early feedback. The first month is when they learn your building, and the specific notes you give in week one are what they’ll be working from for years.

9. Common Mistakes When Switching

  • Giving notice before the new vendor is lined up
  • Missing an auto-renewal window
  • Forgetting to change alarm codes or recover keys
  • Comparing quotes on price without comparing scopes
  • Not writing down what went wrong last time, so it happens again
  • Assuming the new vendor supplies consumables when they don’t
  • Skipping the first-week walkthrough and waiting for problems to appear
  • Carrying a vague scope from the old contract into the new one

Most of these come down to the same root cause: an unwritten scope. A switch is the ideal moment to fix it.

Why Switching Is Easier Than It Looks

The effort involved in changing cleaning companies is front-loaded and short — a few walkthroughs, a notice letter, a key count, and a new start date. The cost of not switching is ongoing and mostly hidden: staff time spent covering gaps, the appearance of the building to clients, and the gradual slide in standards that follows a vendor who knows nobody will act.

The businesses that switch well tend to do three things: they choose the new vendor before giving notice, they take the security handover seriously, and they use the change as a chance to write down exactly what they expect. With those three in place, most transitions happen with no gap in service at all.

Frequently Asked Questions

Q1: How much notice do I need to give my cleaning company?

That depends on your contract. Most commercial cleaning agreements require 30 to 60 days’ written notice. Check how notice must be delivered and whether the agreement auto-renews, since missing a renewal window can extend the term.

Choose and sign with the new vendor before giving notice, then set the new vendor’s start date for the day after the outgoing vendor’s final service. With that order, the changeover can happen on consecutive nights.

Usually two to three weeks to evaluate and select a new vendor, plus whatever notice period your current contract requires. If the current vendor has stopped providing service, most established companies can start within days.

Recover and count every key, fob, and access card from the outgoing vendor on or before their last day, change or deactivate their alarm codes, and re-key if anything can’t be accounted for. Then issue access to the new vendor under a documented process.

Many contracts allow termination for cause, sometimes after a written notice and a cure period. Document the issues in writing when you raise them. For contracts with significant termination terms, have your attorney review before acting.

Sometimes. Some vendors install and own their dispensers and remove them when they leave. Confirm who owns yours and whether the new vendor supplies consumables before the changeover.

In writing, following the method your contract specifies, stating the final service date and arranging the return of keys and equipment. Keep it brief and professional.
