Who Buys From Commercial Cleaning Companies?

Plays That Work
In short 5 outbound plays for commercial cleaning companies, each tied to a trigger you can spot.
| Play | Channel | Trigger | Angle |
|---|---|---|---|
| New office or clinic opening | A new lease, build-out permit or opening date is announced for an office or medical practice. | Write to the office manager or practice administrator before move-in, while they are choosing vendors for the new space. | |
| Example first lineWith [Company]'s new space opening soon, I can walk it before move-in and give you a fixed monthly price for nightly cleaning. | |||
| Building changes hands | Email and LinkedIn | A sale is recorded or a new management company is announced for an office or medical building. | Write to the property manager at the new owner or management firm while they review the building's service contracts. |
| Example first lineCongrats on taking over the building, and if the janitorial contract is up for review, I can bid the common areas and tenant floors this month. | |||
| In-house custodian job posting | The company posts a job for a janitor, custodian or day porter. | Write to the Director of Operations or HR lead about covering the role with a contract crew that handles absences and supplies. | |
| Example first lineI saw [Company] is hiring a custodian, and a contract crew can cover the same hours with backup staff for sick days and supplies included. | |||
| Medical practice adds a location | The practice opens a new location, adds providers or adds exam rooms. | Write to the practice administrator about cleaning exam rooms and waiting areas after close, so staff start the day without cleanup. | |
| Example first lineCongrats on the new [Company] location - we clean exam rooms and waiting areas after close, so your staff open each morning to a clean office. | |||
| School summer deep clean | Spring, while schools plan summer maintenance for the weeks the building is empty. | Write to the facilities director at a private or charter school about a summer floor and deep-clean project that can lead to the school-year contract. | |
| Example first lineBefore [Company] closes for the summer, we can strip and refinish floors and deep-clean classrooms for a fixed price while the building is empty. | |||
Campaigns or 1:1 Accounts?
In short With 196,463 buyers and a typical deal of $7,200-$42,000 (estimate), volume outbound in Campaigns fits best.
| Check | Commercial Cleaning Companies | Points to Accounts (Coming) when |
|---|---|---|
| Typical deal (estimate) | $7,200-$42,000 (first-year value of one monthly janitorial contract), midpoint $24,600 | Over $15,000 |
| Buyer companies in Ken's database | 196,463 | Fewer than 25,000 |
| Suggested lane | Campaigns | Both checks pass |
Ken's estimate: 12 months of a $600-$3,500 monthly contract, which pays for about 20-120 cleaner hours a month at the $17.71 median janitor wage in the source plus payroll costs, supplies and margin.
Ken's view: when one deal is worth more than $15,000 and there are fewer than 25,000 buyers, each account is worth researching and writing to one by one. Otherwise volume wins: a Campaign of short email and LinkedIn sequences reaches more of the market for the same effort.
Objections
In short What buyers tend to say back to commercial cleaning companies, and how to answer.
| Objection | How to answer |
|---|---|
| We already have a cleaning company. | Understood. Let me walk the space once and quote it, so you have a price on file the next time the contract comes up or service slips. |
| Your price is higher than our current vendor. | Ask both vendors how many cleaner hours per night their price covers. If ours costs more for the same hours, tell me and I'll take another look. |
| Our own staff handles it. | That works until someone is out or quits. A contract crew covers nights, absences and supplies for a fixed monthly price, and your team gets those hours back. |
FAQ
How do commercial cleaning companies get clients?
In Ken's view, most contracts come from referrals, property managers who control several buildings, and walk-throughs that turn into quotes. Outbound reaches office managers, practice administrators and property managers when a move, an opening or an ownership change puts the cleaning contract up for review.
How do I get government janitorial contracts?
Federal work starts with registering your business in SAM.gov, which gives you the Unique Entity ID the SBA says you need before you can bid. You also match your services to a NAICS code and search open opportunities under it. State, city and school district bids run through their own procurement offices.
What should the first email say?
Name the building or event you noticed, say what you clean and how often, and offer a walk-through with a fixed monthly price. Office buildings are usually cleaned after hours, so the buyer rarely sees your crew; tell them how you prove the work got done.
What does the CAN-SPAM Act require of a cold email?
In the US, the CAN-SPAM Act covers commercial email, and the FTC says it makes no exception for business-to-business email. Its requirements: no false or misleading header information, no deceptive subject lines, identify the message as an ad, include your valid physical postal address, tell recipients how to opt out, honor opt-outs within 10 business days, and monitor anyone who sends email on your behalf. Other countries have their own rules. This is general information, not legal advice.
