Selling a commercial cleaning company

Commercial cleaning has the shape buyers look for: the same work at the same sites on a fixed schedule, in a market split between a few national providers and a long tail of local, often owner-run companies. ABM says the low cost of entry keeps the business very competitive¹. When Boyne Capital launched a cleaning platform with H&B Facility Services of New Jersey in May 2026, it called the sector highly fragmented and said it would grow by partnering with regional operators².

Labor is the other driver. Janitors and building cleaners held about 2.4 million jobs in 2025, and the Bureau of Labor Statistics projects about 321,800 openings a year through 2035, mostly to replace people who change occupations or leave the workforce⁴. A company that can hire, train and keep crews, with supervisors who know each building, gives a buyer something it cannot build quickly.

Whether you would be a platform or an add-on shapes the conversation. A platform needs a management team, systems and enough contract revenue to anchor a region. An add-on buyer already has that structure, so it focuses on your contracts, your crews and how your sites fit its territory. Add-ons are usually simpler deals.

You will usually hear from five kinds of buyers:

• National providers: large cleaning and facility companies that fold acquired accounts into their branches. ABM, for example, bought LMC FM, a Dublin facilities services company, in June 2025¹.
• Private equity-backed platforms: companies built to grow by acquisition. In July 2026, 4M Building Solutions, backed by O2 Investment Partners, bought Bluegrass Commercial Cleaning in Kentucky and Rainbow Maintenance Services in Illinois, its 15th and 16th acquisitions since January 2023⁵.
• New platforms: a sponsor making its first investment in the sector, as Boyne did with H&B² and as Talus Holdings did when it launched Headwater Cleaning in the Twin Cities in August 2026³.
• Minority and growth investors: capital for an owner who wants to keep control. When Blue Sage Capital invested in Clean Team of Toledo in September 2026, the founder stayed on as CEO and kept majority ownership⁶.
• Holding companies and family offices: investors with longer horizons. Talus tells sellers it has no investment timelines or outside shareholders³.

Buyers start with how you get paid. ABM's annual report describes the common arrangements: a fixed monthly fee, a monthly fee based on square footage, cost-plus pricing in which the client reimburses labor and other costs plus a margin, and work orders for extra jobs such as construction cleanup¹. The first three are your recurring base. Buyers treat work orders as one-time revenue, so report them separately.

Next comes how long that base lasts. ABM says its agreements are generally cancelable by either party on 30 to 90 days' notice¹. Because the paper offers little protection, buyers judge your contracts by their history: how long your top 20 accounts have stayed, how much revenue you kept each year, how many rebids you won and lost, and why customers left. ABM also notes that long relationships tend to be more profitable, since new accounts cost more until staffing settles in¹.

Your end-market mix shapes who will pay most. ABM warns that hybrid work and high office vacancy could reduce demand for office cleaning¹, while hospitals, schools, distribution centers and plants need service every day. Recent announcements stress diversified customers, as with the distribution, medical, government and education clients 4M pointed to at Bluegrass⁵. Specialized work draws its own buyers: in September 2026, Promera, backed by Angeles Equity Partners, bought two UK and Ireland firms that provide contamination control for data centers⁷.

Margin by account matters more than margin in total. Labor is most of the cost: at ABM, direct labor equaled 68 percent of revenue in fiscal 2025¹. The federal minimum wage is still $7.25, but many states, including California, Oregon and Virginia, adjust theirs every year by formula⁸, and ABM notes that those increases can lift pay for workers above the minimum too¹. Buyers look for escalators tied to wages or inflation, and a record of passing increases through without losing accounts.

The labor model comes next. Buyers generally prefer crews you employ directly, because you control hiring, training and quality, and the classification question is settled. Blue Sage singled out Clean Team's direct-employed workforce⁶, and Inspirit Equity described Carlson Building Maintenance, which agreed in July 2026 to join its portfolio company Sizemore, as fully self-performing⁹.

Finally, buyers want proof that quality does not depend on you: written scopes for every site, scored inspections, supervisors with clear territories and complaint logs. Headwater, for example, runs each account against a written scope and shares scored inspections with the client³. ISSA, the cleaning industry's trade association, offers the Cleaning Industry Management Standard, or CIMS, a certification awarded after an assessment and open to contractors of any size¹⁰. You do not need it to sell, but it shows a buyer a working management system.

Buyers find most of these issues early in diligence, so find them first. Few end a deal on their own, but each tends to move part of the price into an earnout, a holdback or a lower offer. The most common:

• One large customer. If one property manager, school district or manufacturer is a big share of revenue, a single cancellation notice could take a large slice of profit.
• Accounts without paper. Handshake arrangements, expired agreements and scopes that no longer match the work are hard to value and hard to transfer.
• High turnover and thin supervision. Constant rehiring raises training costs and hurts quality.
• Worker classification. The IRS looks at behavioral control, financial control and the type of relationship to decide whether a worker is an employee, and a business that treats an employee as a contractor without a reasonable basis can be held liable for the employment taxes¹¹. Subcontract and franchise models draw extra scrutiny.
• Thin or slipping margins. Accounts priced years ago and never repriced as wages rose can run at a loss.
• Union and pension exposure. ABM reports that about 45 percent of its employees are covered by collective bargaining agreements, and that withdrawing from a multiemployer pension plan can create material liabilities¹. If your crews are union, estimate your potential withdrawal liability before a buyer asks.
• Owner dependence. If you hold every facility manager relationship and price every bid, a buyer has to wonder what stays after you leave.
• Insurance and compliance gaps. Lapsed certificates, open workers' compensation claims, missing state registrations and incomplete employee files all surface in diligence.

Your contracts are what a buyer is paying for, so how they move to a new owner matters. In a stock sale the contracting company stays the same, though some agreements allow cancellation after a change of control. In an asset sale each contract has to be assigned to the buyer, and many cleaning agreements require the customer's written consent first. List the agreements that need consent, and agree with the buyer on how and when to ask.

Government work has its own rules. Federal law bars a contractor from transferring a government contract to a third party, but the government may recognize the buyer of the business, or of the assets used to perform the contract, as the successor through a novation agreement¹³. A novation is generally unnecessary in a stock purchase where the contracting company stays the same and keeps performing the work¹³. Federal service contracts over $2,500 also require paying at least locally prevailing wages and fringe benefits under the McNamara-O'Hara Service Contract Act¹⁴, and buyers will check that you have.

Some states regulate janitorial employers directly. California requires janitorial employers to register with the Labor Commissioner and renew every year, with a $500 renewal fee¹². Its law reaches companies that provide cleaning through subcontracts or franchise arrangements, counts franchisees and independent contractors who mainly work as janitors as covered workers, and requires in-person sexual violence and harassment prevention training every two years¹². If you work in California, have your registration and training records in order, and ask your attorney whether a buyer's entity needs its own registration. Check whether your state or city has similar rules.

Smaller cleaning deals are often asset purchases, in which the buyer takes your contracts, equipment and name, offers jobs to your crews, and leaves most other liabilities with you. Larger deals more often transfer ownership of the company itself, which can avoid assigning every contract. Either way, the customer relationships are the core of what is bought; ABM records acquired customer contracts and relationships as an intangible asset¹.

Because notice periods are short, part of the price is often tied to whether customers stay. When ABM bought LMC FM in June 2025, it paid about $22.5 million in cash and agreed to pay up to $5.8 million more in 2027 if the top two customers are retained¹. If your earnout is measured on retained revenue, the definitions decide what you are paid. Agree in writing on how a rebid lost on price is counted, what happens when a customer cuts its scope or a tenant moves out, and who controls pricing and staffing after closing.

Rollover equity is common when a private equity firm is building a platform: you reinvest part of your proceeds in the larger company for a second payout if it grows. Rainier Partners, which bought Kleen-Tech Services in September 2025, says it typically invites founders or management teams to invest alongside it¹⁵. Some owners keep control instead, as Clean Team's founder did⁶. Either path carries real risk, so it makes sense only if you trust the plan and the people.

Expect a transition period as well, in which you introduce the buyer to your largest customers and key supervisors stay on. Many buyers keep local names: under its agreement with Sizemore, Carlson keeps its name and its owners continue to lead it⁹, Kleen-Tech operates under nine brands¹⁵, and Shore Capital Partners' Maintera platform kept the names of the two companies it combined¹⁶. Smaller deals may also include a seller note and, if you own your building, a lease to the buyer.

A buyer's confidence comes from data it can check. Start a year or two out, so your numbers have a track record when someone asks:

• Build a contract inventory: one row per account and site, with scope, square footage, frequency, monthly billing, start date, term, renewal date, notice period, escalator, assignment clause and last price increase.
• Calculate margin by account every month from actual labor hours, wages, supplies and supervision, and reprice or exit the accounts that lose money.
• Track retention: revenue kept from existing customers each year, every lost account with the reason, and rebids won and lost.
• Keep a labor history: headcount by month, turnover, tenure, wage rates by market, overtime and workers' compensation claims.
• Review how your crews and any subcontractors are classified with an employment attorney before a buyer does.
• Write down your quality system, from site scopes to inspection scores and complaint logs, and decide whether CIMS certification is worth pursuing.
• Separate recurring contract revenue from work orders in your financial statements, and reconcile them to your tax returns.
• Put a manager between you and your largest customers, so the relationships belong to the company.
• Gather insurance certificates, loss runs, any bonds customers require, state registrations and union agreements in one place.
