Red flags when buying a cleaning or janitorial business

Common seller tricks in cleaning or janitorial

A contract list can look like recurring revenue while every account is 30 days from walking, and while the seller is still the quality-control person on the flagship floors.

• Including accounts that are month-to-month, already under rebid, or promised a price the P&L cannot support.
• The owner or a family member still cleaning the largest buildings.
• Turnover so high that quality — and therefore renewals — depends on the seller’s nightly presence.
• Supplies marked up in a way a new owner cannot repeat, or supplies absorbed so margins look better than they are.
• Underestimated labor because overtime and no-shows never hit the sample month.

Which numbers to verify

List every account with monthly billing, start date, termination terms, and whether a bid is pending. Reconcile deposits. Look at labor hours against square footage. Recast the owner’s nights in the buildings. Supplies, equipment, and vehicle costs should be complete. If wages have to rise to keep the crew, the SDE is already stale.

Licensing and key-person risk

Bonding, janitorial licenses, and sometimes security or after-hours access rules apply. Background-check requirements are often in the customer contract. Insurance (including bonding and, for some sites, specific additional insureds) should be reviewed so you know the cost of staying compliant after close.

Equipment and condition

Autoscrubbers, buffers, and vans have hours and remaining life. Cheap equipment that dies in six months is a price adjustment. If crews use their own cars, that is a risk, not a savings. Check where chemicals are stored and whether SDS and safety practices would pass a customer audit.

Seasonality and the calendar

Commercial cleaning is steadier than most trades, but school, church, and some office work still follows a calendar. Retail and construction-cleanup add-ons can puff a year. The bigger ‘seasonality’ here is turnover: around holidays, crews disappear and quality slips.

Customer concentration

One hospital, one property manager, or one office park can be a third of the profit. Read those termination and rebid clauses. If the owner has a personal relationship with the facility manager, plan on a joint visit well before close — and do not assume the account is yours.

Questions to ask before you make an offer

1. Please provide a current account list with monthly billing, start dates, and termination or bid terms.
2. What share of revenue sits in the largest five accounts, and when is each up for rebid?
3. Which buildings does the owner or a family member still clean or inspect weekly?
4. What have wages, overtime, and turnover been for the last two years?
5. May I see bonding, insurance, and background-check requirements for the larger sites?
6. How are supplies billed, and can I review a sample of invoices to customers?
7. What equipment is included, with hours and remaining life?
8. Are any accounts already late, in dispute, or verbally promised a price cut?
9. Will building access credentials transfer, and what is required from each customer?
10. After an LOI, may I visit the top accounts with you and speak with your accountant?
