Commercial cleaning leads: how to find office, medical and industrial cleaning clients

This guide is for owners and sales leads at commercial cleaning and janitorial companies who want more contract clients: offices, medical practices, industrial plants and government buildings. It covers how big each market is, who hires the cleaner in each, what they'll ask you, where to get a free list of each kind of building, and a worked plan for one county.

How many cleaning companies and clients there are

County Business Patterns, the Census Bureau's count of business locations with paid employees, found 67,799 janitorial services establishments (NAICS 561720) in 2023, employing 1,088,193 people. The market is crowded at the small end: 41,548 of them (61%) have fewer than five employees, and 204 have 500 or more. That's who you compete with, and why most buyers already have a cleaner.

The buildings are the bigger number. The Energy Information Administration's latest Commercial Buildings Energy Consumption Survey (2018) counted 5.9 million commercial buildings with 96.4 billion square feet of floor space. The survey leaves out factories, so the industrial row below uses Census counts instead.

Most office buildings are small: 518,000 of the 970,000 have 1,001 to 5,000 square feet, and about 63,000 are over 50,000 square feet. A small-office route and a large-building contract are different businesses with different buyers.

Who hires the cleaner

The person who signs depends on who controls the building, not who works in it.

Two consequences. First, in a multi-tenant building, pitching the tenant usually goes nowhere, because the property manager holds the contract and bills it back through the lease. Second, one property manager can control a dozen buildings, which makes property management firms the highest-value accounts for an office cleaning company.

What medical and industrial clients will ask you

This is general information, not legal advice.

• Medical: bloodborne pathogens. OSHA's bloodborne pathogens standard (29 CFR 1910.1030) requires the worksite to be kept clean and sanitary on a written schedule for cleaning and decontamination, set by surface, type of soil and the procedures done in each area. As the employer of your cleaners, you must train any employee with occupational exposure and make the hepatitis B vaccine available to them at no cost. Practice managers who know the rule will ask to see your training records.
• Industrial: housekeeping. OSHA's walking-working surfaces rule (29 CFR 1910.22) requires workplaces, passageways and storerooms to be kept "clean, orderly, and sanitary" and floors kept clean and, where feasible, dry. That gives plant and EHS managers a safety reason to buy, not just an appearance one.
• Food plants. FDA's food safety rule (21 CFR 117.35) requires food facilities to keep the plant clean and sanitary and to protect against allergen cross-contact. Expect written sanitation procedures and chemical approvals.
• Federal contracts. The Service Contract Act requires contractors on federal service contracts over $2,500 to pay the locally prevailing wages and fringe benefits in the contract's wage determination. To count as a small business for janitorial contracts, average annual receipts must be $22 million or less under the SBA size standard.

USAspending shows that federal agencies obligated $1.79 billion on janitorial services contracts in fiscal 2025. The Department of Defense accounted for $1.21 billion, followed by Homeland Security ($110 million), Veterans Affairs ($109 million) and the General Services Administration ($67 million). Each award shows when its current period of performance ends, which tells you when the rebid is likely to post. For how federal buying works, see selling to the government.

Segment and time your outreach

• Building type. Pick one first. Medical, office and industrial cleaning need different crews, chemicals and proof.
• Size. Square footage sets crew hours and the price. Use headcount from OSHA or CBP size bands as a proxy until you walk it.
• Who controls the building. Owner-occupied or managed by a property firm.
• Triggers. A new building or fit-out, a move, a new practice or plant manager, a recent expansion, a federal contract nearing its end date. A new manager often reviews vendors in their first months.
• Contract terms. Ask how long they've had their current cleaner, what notice their contract requires and what they'd change. A short notice period means an unhappy buyer can switch this quarter.

Worked example: medical cleaning leads in Columbus, Ohio

Illustrative example. The cleaning company and its plan are fictional; the counts come from County Business Patterns 2023 for Franklin County, Ohio.

The seller: Brightline Facility Care (brightline-care.example) cleans medical offices and wants more of them. The territory: Franklin County, which includes Columbus.

1. Size the market. Franklin County has 272 physician offices, 184 dental offices and 169 outpatient care centers with 10 to 99 employees: 625 practices large enough to need nightly cleaning. It also has 259 janitorial establishments competing for them.
2. Get the names. Search the NPI Registry for organizations in the county's ZIP codes by specialty. Each record gives a practice address, phone and an authorized official, often the practice manager or owner.
3. Remove the ones you can't win directly. If an illustrative 30% sit in hospital-owned or multi-tenant buildings where the property manager or health system hires the cleaner, about 440 practices remain. Put the property managers on a separate list.
4. Do the arithmetic. Contact 200 practices in a quarter. At an illustrative 8% rate of booked walk-throughs, that's 16 walk-throughs. Win an illustrative quarter of them and you add 4 accounts. At an illustrative $1,800 a month for a 5,000 square foot clinic cleaned five nights a week, that's $86,400 a year of recurring revenue.
5. Write to the practice. Lead with their world, not your services:

Subject: After-hours cleaning at [practice name]

Hi [first name],

I run [company], which cleans [number] medical and dental offices in [area], including [type of practice similar to theirs].

Practices like yours usually tell us the same two things matter: exam rooms decontaminated on a written schedule, and a crew that's the same people every night.

Our cleaners are trained under OSHA's bloodborne pathogens standard, and I can send you our training records and insurance certificate before we meet.

Could I walk the office one evening next week and give you a written quote? It takes about 30 minutes.

[Your name]
[Phone]

Bring a checklist to every walk-through, so the quote reflects the building and not a guess:

Building: [address], [square feet], [floors]
Contact: [name, role], decides with: [names]
Current cleaner: [company], how long: [years], notice period: [days]
What they'd change: [their words]

ROOMS
Exam or treatment rooms: [count]   Restrooms: [count]
Offices: [count]   Break rooms: [count]   Lab or sterilization: [yes/no]
Floors: [carpet / vinyl / tile, square feet of each]

REQUIREMENTS
Frequency: [nights per week]   Access window: [times]
Written cleaning schedule needed: [yes/no]
Waste handling: [what we handle, what we don't]
Chemicals approved by the facility: [list]
Keys, alarm codes, sign-in: [process]

PROOF THEY ASKED FOR
[insurance, bonding, training records, references]

QUOTE DUE: [date]

Finding the right manager at each of hundreds of practices or plants is the slow part; Bebop finds matching businesses and contacts and writes a playbook for each account.

Common mistakes

• Buying shared leads. If five cleaners get the same name, the buyer picks on price.
• Quoting by phone. Without a walk-through you'll misprice the restrooms, floors and access hours.
• Pitching tenants in managed buildings. Find the property manager.
• Treating medical like office cleaning. Clinics will ask about decontamination and training. Have the proof ready.
• Chasing federal bids without the paperwork. You need an active SAM.gov registration and a wage plan that meets the contract's wage determination.

Next step: pick one building type and one territory, then follow lead generation for small business to build a weekly outreach routine around it.
