Starting a commercial cleaning business is one of the more accessible paths to entrepreneurship — low startup costs, recurring revenue, and steady demand from offices, schools, and medical facilities. But "accessible" doesn't mean easy. Without the right structure, most new operators stall out after landing their first two or three clients.
Understand the Market Before You Start
Commercial cleaning isn't one market — it's several. Office buildings, medical facilities, schools, industrial warehouses, and retail spaces all have different requirements, frequencies, and compliance standards. Decide early which verticals you'll target.
Medical facilities, for example, require OSHA and HIPAA awareness training, specific disinfectants, and often bonded staff. Office cleaning is more forgiving but highly competitive on price. Picking a niche lets you charge more and build a reputation faster.
Legal Setup and Licensing
Before signing a single contract, get your business structure in order:
- Form an LLC or corporation — this protects your personal assets from liability claims
- Get a business license in your city or county (fees typically run $50–$150)
- Obtain general liability insurance — minimum $1 million per occurrence; most commercial clients require proof before you step on-site
- Add a janitorial bond — usually $10,000–$50,000, which protects clients from employee theft
- Register for an EIN with the IRS if you plan to hire employees
Budget around $500–$1,500 to get fully legal and insured before your first job.
Equipment and Supplies
Don't overbuy at the start. A solo operator or two-person crew cleaning offices can launch with:
- Commercial vacuum (backpack-style preferred) — $200–$500
- Microfiber mop system — $80–$150
- Trigger sprayers, buckets, and mop buckets — $100–$200
- HEPA-rated filters for allergen-sensitive clients
- EPA-approved disinfectants and green cleaning options (increasingly required by corporate clients)
As you add floor care or post-construction cleaning, you'll need auto scrubbers, extractors, and pressure washers. Rent those until volume justifies purchase.
Pricing Your Services
Underpricing is the fastest way to burn out. Commercial cleaning typically prices at $25–$55 per hour per cleaner, or as a flat monthly contract rate. For office cleaning, a common formula is:
- Square footage × cleanable area percentage × frequency factor × your hourly cost
A 5,000 sq ft office cleaned three nights per week might run $800–$1,500/month depending on your market and scope. Always walk the space before quoting — photos and guesswork lead to losing money.
Factor in labor, supplies (typically 5–8% of revenue), equipment depreciation, insurance, and your profit margin before you name a number.
Landing Your First Contracts
Cold outreach still works in this industry. Specific tactics that generate results:
- Door-to-door canvassing in office parks and light industrial zones — bring a one-page capability sheet and leave a quote offer
- Google Business Profile — set it up immediately and collect reviews from every client you land
- Local networking groups like BNI or Chamber of Commerce events, where property managers and office managers are common members
- Property management companies — one relationship can unlock a portfolio of buildings
- Subcontracting under an established janitorial firm to build experience and cash flow before going fully independent
Getting listed on a marketplace like Mercoly puts your services in front of facility managers and business owners actively searching for janitorial contractors — a direct channel to inbound leads without heavy ad spend.
Writing a Solid Janitorial Contract
Never start work without a signed agreement. Your contract should specify:
- Scope of work (exactly what gets cleaned, how often, by whom)
- Frequency and time windows for service
- Supplies responsibility (client-provided or contractor-provided)
- Payment terms (net 15 or net 30 is standard; avoid net 60)
- Cancellation clause (typically 30–60 days written notice)
- Liability and insurance provisions
Use a simple, plain-language contract. Clients are more likely to sign something they can read and understand. A template from a janitorial industry association or a one-time review by a local business attorney ($150–$300) is worth the investment.
Hiring and Scaling
Once you're reliably billing $10,000+/month, it's time to hire. Background checks are non-negotiable — every client will expect it. Classify workers correctly (W-2 employees vs. 1099 depends on control and relationship), stay current on payroll tax obligations, and build simple checklists so quality doesn't slip as your team grows.
Operational systems — scheduling software, inspection checklists, client communication protocols — are what separate businesses that scale from those that plateau.
The commercial cleaning industry rewards operators who combine reliability with professionalism; build that reputation from your first contract and the referrals will compound.
