A commercial cleaning contract is a recurring agreement to clean a building on a schedule, usually priced monthly. It is what turns a cleaning company from a set of jobs into a business with predictable income. There is no single way to win them. Public bids, property managers, referrals, your own sales and outside leads each find a different buyer. This page lays out every route, what each one takes, how fast it pays, who controls it, and where LeadWharf fits among them. If you want a step-by-step plan to follow each week instead, read our guide on how to get commercial cleaning contracts.
What are the main ways to get commercial cleaning contracts?
The main ways to get commercial cleaning contracts are public bids, government portals, property managers, referrals, your own outbound sales, and bought or outsourced leads. Here is how they compare.
| Route | Who the buyer is | Speed to first contract | Competition | Who controls the flow | What it takes |
|---|---|---|---|---|---|
| Public bids (city, county, school, state) | Procurement officers, facilities departments | Slow: follows the bid calendar | High: open to all registered vendors | The buyer sets every date | Registration, bonding or insurance paperwork, sharp pricing |
| Federal contracts (SAM.gov) | Federal agencies and prime contractors | Slow | High | The agency and its solicitation | Full SAM.gov registration, past performance, compliance |
| Property managers | Managers of offices, retail centers, industrial parks, HOAs | Medium | Medium: relationships matter | You, through one person you must keep | Reliability, insurance, fast response to issues |
| Referrals | Anyone who knows a happy client | Unpredictable | Low | You, indirectly, through your service | Existing clients who love you |
| Your own outbound | Office, practice, plant and facility managers | Medium | Medium | You, for as long as you keep sending | Time, a list, a sending setup, persistence |
| Bought or outsourced leads | Whoever the source reaches | Fast to start | Depends: shared or exclusive | The provider, until the contact is in your hands | Budget, fast follow-up, tracking |
Competition on every route is real. The U.S. Census Bureau counted 67,799 employer establishments in janitorial services in 2023 (Census CBP via StartBusinessByState), before counting the many owner-operators with no employees. The companies that grow tend to run several routes at once rather than waiting on one.
How do you win janitorial contracts through public bids?
You win janitorial contracts through public bids by registering with the right portals, reading every requirement in the solicitation, attending the site visit, and submitting a complete, well-priced bid on time. Public bids reward discipline more than salesmanship.
Where they are posted:
- City and county procurement pages. Most local governments post bids on their own site or a bid platform they subscribe to.
- School districts, colleges and universities. Each usually runs its own purchasing office.
- State procurement portals. Every state has one; registration is usually free.
- Bid aggregators. Paid services collect bids from many sources into one feed. Useful once you bid regularly.
What wins them:
- Read the whole solicitation. Missing a signature, a form or a deadline disqualifies good bids every week.
- Go to the pre-bid walk-through, even when optional. You will see what the drawings do not show.
- Price the scope as written, not the building you imagine. Public buyers compare line by line.
- Show past performance. References from similar buildings carry weight.
- Ask for the bid tabulation afterward. Seeing the winning price teaches you the market.

How do you get government cleaning contracts on SAM.gov?
You get federal cleaning contracts by completing full registration on SAM.gov, listing the janitorial NAICS code, and responding to solicitations posted there. SAM.gov states that full registration is what lets you bid on federal contracts, that a Unique Entity ID alone does not let you apply directly for awards, and that registration can take up to 10 business days to become active (SAM.gov).
Federal janitorial work is generally classified under NAICS 561720, Janitorial Services. The SBA's size standard for that code is $22.0 million in average annual receipts, which is the ceiling for being treated as a small business on set-aside contracts (SBA table of size standards, effective March 17, 2023). Search SAM.gov with more than one word: "janitorial," "custodial" and "housekeeping" can all describe the same work.
In Canada, federal tenders are published on CanadaBuys, the Government of Canada's procurement platform, which also covers parts of the broader public sector. Provinces and municipalities run their own portals as well, and MERX collects many Canadian tenders, including municipal ones, in one place.
Government contracts pay reliably and can run for years, but the paperwork is heavy and prices are competitive. Our guide to government cleaning contracts goes deeper, and the government building cleaning leads page covers the buildings and buyers.
How do property managers hand out cleaning contracts?
Property managers hand out cleaning contracts to companies they trust to keep tenants happy without calls at 7 a.m. about missed trash. One good property manager can control many buildings, which makes them one of the most valuable relationships a janitorial company can have.
They usually buy in one of two ways: a formal request for proposals across a portfolio, or a quiet switch when the current cleaner lets them down. The second is far more common and far less visible. The way in is to be known before that happens: introduce yourself, deliver on a small building, and respond fast when something goes wrong. See how to find property managers for cleaning contracts and property management cleaning leads.
How do referrals turn into cleaning contracts?
Referrals turn into cleaning contracts when happy clients, other trades and local business contacts mention you at the moment someone is unhappy with their cleaner. They close well because trust arrives with the introduction.
You cannot control referral volume, but you can make it more likely:
- Ask every happy client, directly, who else they know who manages a building.
- Build relationships with trades that work in the same buildings: HVAC, pest control, window cleaners, facility maintenance.
- Join a local business group and show up regularly.
- Make it easy: a short line in your emails, a card on the supply closet door.
How do you win cleaning contracts with your own outbound sales?
You win cleaning contracts with outbound sales by building a list of the buildings you want, finding the decision-maker in each, and contacting them consistently by email, phone or in person. Outbound reaches the large group of buyers who are unhappy with their cleaner but have not started looking, which is why many private contracts start this way.
It takes a list, a sending setup that stays out of spam, a message worth replying to, and weeks of steady follow-up. Done in-house, it usually falls to the owner, and it is the first thing to slip when a crew calls in sick. The channel-by-channel view, including rules on commercial email in the US and Canada, is on janitorial lead generation. Our guide on cold email for cleaning companies covers the writing.
Where do leads fit in winning cleaning contracts?
Leads fit in as a way to start more contract conversations without doing the prospecting yourself. You pay for the finding and qualifying; you still do the walk-through, the quote and the close. The value depends entirely on the quality of the lead, which is why the definition matters so much.
LeadWharf's version is outbound done for you, in your company's name. We agree your area and the buildings you want, find and verify the decision-makers, reach them with personalized outreach, and qualify each reply against three checks: the building is in your area, they want regular work at your frequency and job size, and you are getting the person who signs. You get the contact; you book the walk-through and write the quote.
Every lead is exclusive and your area is locked while you are with us. The pricing is a one-time setup and a flat fee per qualified lead, with nothing monthly and no contract. A lead that misses a check is credited. Judge it on the first lead. See janitorial leads and commercial cleaning leads for more.
Which routes keep producing after you stop paying?
Referrals, property manager relationships and your own prospect list keep producing after you stop spending, while bought leads and paid ads stop the day the budget does. Public bids sit apart: the buyer decides when work appears, and a contract you win is usually re-bid when its term ends.
That split matters for planning. Routes you own get cheaper per contract with time but are slow to start. Routes you rent are fast to start, and the bill never goes away. Two details soften the line:
- A bought lead becomes yours once it is handed over. The provider owns the flow of new contacts, but the relationship with a building you have spoken to is yours to keep, whatever happens to the subscription.
- A property manager relationship is owned but fragile. It belongs to you only as long as that manager stays in the role. When they move company, you can lose a portfolio or gain a new one, so know more than one person at each firm.
A sensible plan funds one fast, rented route to keep crews busy now and one owned route that will carry more of the load next year. To compare routes on what each signed contract actually cost you, and to decide whether a lead generation company earns its place, follow the method in our step-by-step contracts guide.
What makes a commercial cleaning contract worth signing?
A commercial cleaning contract is worth signing when the scope is written down, the price covers the work with room for supplies and wages to rise, and the exit terms are fair to both sides. Winning the contract is only half the job. A badly written one can cost you more than losing the bid.
Read or write every agreement with these points in mind:
| Clause | What to get right | What goes wrong without it |
|---|---|---|
| Scope of work | A room-by-room or area-by-area task list with frequencies | "Clean the building" becomes whatever the client says it means this week |
| Schedule and access | Days, hours, keys, alarm codes, who opens and locks | Crews locked out, alarms tripped, blame for things left open |
| Price and what it includes | Monthly price, whether supplies, paper goods and liners are included | Supply costs quietly eat the margin |
| Price review | A yearly review or an agreed increase tied to wages or costs | Three years at the same price while wages rise |
| Extra work | How one-off requests (floor strip, carpet, event cleanup) are quoted and approved | Free extra work that becomes expected |
| Term and termination | Length, renewal, notice period for either side | Being dropped with no notice, or stuck in a loss-making account |
| Insurance and liability | Required coverage, certificates, who is liable for what | A claim you assumed the client's insurance covered |
| Quality and complaints | How issues are reported and how fast you respond | Small complaints pile up until the client leaves |
Most buyers will accept a clear, fair agreement over a vague one, because it protects them too. If you need a starting point, our commercial cleaning proposal template shows how to present scope and price together.
When is the best time to approach a building about a cleaning contract?
The best time to approach a building is a few months before its current cleaning contract ends, or right after something goes wrong with the current cleaner. Both moments are hard to see from outside, which is why steady contact beats one-off pitches.
Some signals are worth watching for: a building changing owners or property managers, a new tenant moving into a large space, a business expanding into a second floor, a new clinic or school opening, or a public contract that was awarded several years ago and is approaching its end. When you first speak to a building, ask when their current agreement ends and note it. A short check-in two or three months before that date often lands at exactly the right moment.
How do you choose which routes to use?
Choose routes by matching them to your stage, your cash flow and the time you have for selling. A rough guide:
- Just starting: referrals, a few direct conversations with nearby buildings, and small bids you can win on price. Read how to start a commercial cleaning business.
- A few accounts and a steady crew: add property managers and a consistent source of qualified leads, so growth does not depend on the owner's free evenings.
- Established with references: add public and government bids, where past performance counts.
Whatever the mix, track every contract back to where it came from. After a year you will know which routes deserve more of your time. The weekly routine, the ideal client profile and the buying triggers that tell you when to call are all in our guide to how to get commercial cleaning contracts. When you are ready to add a steady flow of exclusive, qualified contract conversations, book a call and bring a map of where you work.
