School cleaning contracts reward patience. The buyer might be an elected board, a charter network's operations office or a private school business manager with a free hand, and each one buys on a different clock. Once you know which kind of school you are talking to, the path to a signed custodial contract is predictable, and the account tends to stay put for years.
This guide is the how-to. It walks through who buys school custodial work, how public district procurement actually runs, when the bids open, what the paperwork looks like, and how to win the schools that never bid at all. For what the school market looks like as a lead source, and who the decision-makers are, see our page on school cleaning leads.
Who buys school cleaning contracts?
Five kinds of buyer purchase school cleaning, and each one decides differently.
| Buyer | Who usually signs | How they buy |
|---|---|---|
| Public school district | Board of education, on the recommendation of the facilities or business office | Formal bid or request for proposals above a legal threshold, or a cooperative contract |
| Charter school | Operations director, COO or the charter network office | Quotes or a light RFP, board sign-off in some cases |
| Private and parochial school | Business manager, CFO or head of school; sometimes a parish administrator | Direct negotiation, sometimes two or three quotes |
| College or university | Facilities or purchasing department | Formal RFP, often by building, campus or service line |
| Preschool and daycare | Owner or center director | Direct, often a phone call and a walk-through |
The table matters because it tells you where to spend your selling time. Districts and universities reward compliance and patience. Charter, private and early learning schools reward the company that shows up first with a sensible plan. Early learning centers have their own health and licensing rules, which we cover on the daycare cleaning leads page.
How do school districts buy custodial services?
Public districts buy custodial services through rules written into state law: below a set dollar amount staff can get quotes, and above it they must use a competitive method and take the award to the board.
The thresholds and methods vary by state, so read your own state's education or municipal code. Two examples show the range:
- Texas. District contracts for goods and services worth $50,000 or more in total over a 12-month period must be bought by a method that gives the district best value, including competitive bidding, competitive sealed proposals, a request for proposals or an interlocal contract (Texas Education Code 44.031).
- New York. General Municipal Law 103 requires sealed bids for purchase contracts above $20,000 and public works contracts above $35,000, and it names school districts and BOCES among the bodies it covers (NY GML 103).
In practice, a district custodial contract follows a familiar path. The facilities office writes a scope of work, purchasing posts the bid with a deadline and usually a mandatory pre-bid walk, vendors submit, staff score the responses, and the board approves the award at a public meeting. Board agendas are public, so they are one of the best free sources of intelligence you have. Search your target district's past agendas for "custodial" to see who holds the contract, what it cost and when it was last renewed.
Most districts post on their own purchasing page or on an aggregator. Our roundup of the best places to find cleaning bids lists the portals worth watching, and our guide to government cleaning contracts covers vendor registration and how public bids are scored in general.
What are cooperative purchasing contracts?
A cooperative purchasing contract is a contract one public agency has already awarded through a competitive process, which other agencies can then buy from without running a bid of their own. Districts use them to save months of procurement work.
OMNIA Partners is one example. Its public sector contract list includes a facilities category with janitorial and cleaning among the supplier categories, and it lists K-12 education, including public school districts and charter schools, among the organizations that can use its contracts, with membership free for buyers (OMNIA Partners contracts, OMNIA Partners Public Sector, both checked October 2026). You will also hear Sourcewell and TIPS named as cooperatives. We could not open their contract pages in October 2026 to confirm a current janitorial award, so check each one's own site for an active custodial or facility services contract before you plan around it.
For a single local cleaning company, getting onto a cooperative contract yourself is a longer game, because the award covers many agencies at once. The useful lesson is to ask any district you approach how they bought custodial work last time, because if the answer is "through a co-op," the next opportunity may be a quote under that contract rather than an open bid.
When do schools put cleaning contracts out to bid?
Schools usually bid cleaning in late winter and spring so a new contractor can start over the summer, when buildings are empty and the new fiscal year begins.
Many school systems budget on a year that starts July 1. In Texas, for instance, a district's fiscal year begins on July 1 or September 1, as its board decides (Texas Education Code 44.0011). Working backward from a July start, a typical district timeline looks like this:
| Month | What is happening inside the district |
|---|---|
| October to December | Facilities staff review the current contractor and decide whether to renew or rebid |
| January to March | Scope written, bid posted, pre-bid walks held |
| March to May | Responses scored, recommendation goes to the board |
| June | Contract signed, onboarding, background checks processed |
| July and August | New contractor starts with summer deep cleaning before students return |
Private and charter schools follow the same calendar loosely, without the paperwork. A business manager who is unhappy in February is often picking a replacement by April. That is why the most useful time to reach any school is in the fall and early winter, before anyone has written a scope. Our post on when businesses switch cleaning companies explains the signs that a building is ready to change.
What do school cleaning bids usually require?
School bids ask for more proof than most commercial bids, and the requirements cluster into five areas. Have each one ready in a folder before bid season starts.
Background checks and fingerprinting
Expect background checks for anyone who will be in the building. Many states set this in law. Texas requires a national criminal history review for contractor employees who will have continuing duties and direct contact with students, and makes a qualified school contractor certify to the district that it has the results for its staff (Texas Education Code 22.0834). Other states have their own versions. Find out how long checks take in your state and who pays, because a crew you cannot clear in time is a contract you cannot start.
Insurance
Bids name minimum limits for general liability, workers' compensation and auto, and often ask for umbrella coverage, a janitorial bond and the school named as an additional insured. Send the bid's insurance section to your agent the day it posts.
Prevailing wage
Some states set wage floors for cleaners on public contracts. New York's Labor Law covers building service employees, including cleaners and janitors, on contracts above $1,500 with public agencies, a definition that includes a board of education, and requires the prevailing wage for the locality (NY Labor Law 230, NY Labor Law 231). Check your state labor department before pricing, because missing a wage rule makes a winning bid unprofitable.
Green cleaning rules
A few states require schools to buy environmentally preferable cleaning products, and the contractor's chemicals must comply. In New York, Education Law 409-i requires elementary and secondary schools, including charter, private and religious schools, to follow state guidelines and a sample product list when buying cleaning products (NY Education Law 409-i). The Office of General Services publishes those guidelines (NYS OGS). Illinois has a Green Cleaning Schools Act that requires schools to adopt a green cleaning policy and buy environmentally sensitive products, with an exemption if it would raise cleaning costs (Environmental Law Institute). Even where no law applies, a short product list with certifications reads well to a facilities director.
Staffing and supervision plan
Districts want to see how many people you will put in each building, who supervises them and how you cover absences. More on this below.
How do you size and staff a school cleaning bid?
Size a school bid by cleanable square feet per custodian at the level of clean the school wants, then check it against the bell schedule.
APPA, the association for education facilities professionals, publishes custodial staffing guidelines built around five appearance levels, from Level 1 ("orderly spotlessness") to Level 5 ("unkempt neglect"). Its figures show how fast the workload changes with the standard: one full-time custodian covers about 21,306 square feet of classroom at Level 2 but about 38,513 at Level 3, and restrooms at Level 2 need one custodian per roughly 3,303 square feet (APPA). APPA also recommends measuring cleanable square feet rather than gross square feet, because many spaces in a building are never cleaned by the custodial staff.
Ask the school which level it expects, write it into your proposal and price to it. A bid that quietly assumes Level 3 when the board wants Level 2 is how contractors lose money in year one and lose the contract in year two. Our guide on how to bid a janitorial job covers production rates and labor math in detail.
Then plan around school hours:
- Day porter. Many schools want one person on site during the day for restrooms, spills and the cafeteria. Price it as its own line.
- Evening crew. Main cleaning starts after dismissal, but gyms and cafeterias may be in use for sports, concerts and community events. Get the events calendar.
- Holidays and breaks. Crews may need fewer hours during winter and spring break, or more if those weeks are used for project work.
- Supervisor. Name one person the head custodian or principal can call. Schools judge you on how fast problems get fixed.
- Safeguarding rules. Badges, sign-in at the front office and a clear rule that staff do not interact with students.
How do you win private and charter schools without a bid?
Win private and charter schools by reaching the business manager or operations director directly, well before summer, with a specific plan for their building.
These schools are not bound by public procurement rules, so the decision often sits with one or two people. The steps that work:
- Find the person who signs. At a private school it is usually the business manager or CFO; at a small one, the head of school. At a charter, the operations director or the network office.
- Make contact in the fall or early winter. That is when frustration with the current cleaner builds and before a replacement has been chosen.
- Ask for a walk-through after dismissal. See the restrooms, cafeteria and gym at the end of the day, when the real workload is visible.
- Bring safeguarding answers unprompted. Background checks, staff consistency and how you handle keys and alarm codes matter to parents, so they matter to the business manager.
- Offer a trial. A summer project, a single building or a 90-day start lets a cautious school test you without a big commitment.
- Follow up on the school's calendar. Board or finance committee meetings set the decision date. Ask when it is and follow up the week before.
Parochial schools add one more layer: the parish or diocese may have a say, or an existing cleaner may also clean the church. Ask early who else needs to approve.
Why is summer work the best door into a school?
Summer deep cleaning is the easiest way into a school because it is scheduled every year, often bought separately, and lets the school judge your work before trusting you with the nightly contract.
Typical summer scopes include floor stripping and refinishing, carpet extraction, high dusting, locker and desk cleaning, window washing and gym floor preparation. Many schools rely on their in-house custodians for this and fall behind, or their current contractor rushes it. Either way, the facilities director remembers which company left the hallways shining in August.
Treat a summer job as a sales call that pays. Finish early, photograph the result, and ask for a meeting in the fall to talk about the recurring contract. Colleges and universities buy the same kind of project work between terms, and it can be a way onto their approved vendor list.
What does a strong school cleaning proposal include?
A strong school proposal answers the board's fears before it lists the price. Use this checklist:
- Scope by space type, with frequencies, matched to the school's chosen level of clean
- Staffing plan by building and shift, with a named supervisor
- Background check process and how long it takes to clear new staff
- Insurance certificates at the limits the bid asks for
- Product list showing compliance with any state green cleaning rule
- Wage compliance statement where prevailing wage applies
- Summer and break work priced as separate lines
- Quality inspections and how complaints are logged and closed
- References from other schools or comparable large buildings
- Transition plan for the first two weeks
If you have no school references yet, use your largest comparable accounts and offer a trial building. Schools are cautious, but a clear transition plan goes a long way.
Where should you start?
Start by listing every school within a reasonable drive of your current routes and sorting them into the five buyer types. Register as a vendor with the districts, set bid alerts, and pull last year's board agendas to see who holds each custodial contract and when it ends. Then spend the fall talking to private, charter and early learning schools directly, because those are the accounts you can win this year without waiting for a bid.
The hardest part is usually finding out which school is unhappy before the business manager starts calling around. If you want school conversations in your area handed to you, LeadWharf contacts schools in your name, checks that each one wants recurring cleaning and that you are speaking to the person who signs, and sends that lead to you alone, paid per qualified lead. You can book a call to talk through your area and the schools you want.
