Janitorial work is different from residential cleaning: you're servicing offices, retail stores, medical facilities, and other commercial spaces, usually on evenings or weekends, often under multi-month or multi-year contracts. That means different pricing math, different insurance requirements, and a different sales process. Here's how to set one up properly in the US (with UK notes where relevant).
Janitorial vs. residential cleaning: know the difference
Janitorial services typically cover commercial buildings — offices, gyms, schools, warehouses, medical offices, retail. Clients want consistency, discretion, after-hours access, and compliance paperwork (insurance certificates, background checks). Contracts tend to be longer and higher-value than residential jobs, but sales cycles are slower and clients expect professionalism from day one.
If you're weighing which type of business to build, or want the full step-by-step on entity setup, insurance, and pricing basics, see our complete guide: How to start a cleaning business. This article focuses specifically on the commercial/janitorial side.
Step 1: Choose your business structure
Most janitorial businesses in the US start as one of these:
- Sole proprietorship — simplest, no separate filing, but you're personally liable for any damage or injury claims on a client's property. Risky for commercial contracts.
- LLC (Limited Liability Company) — separates personal and business assets. Costs vary by state ($50–$500 filing fee), and most janitorial contracts with commercial landlords or property managers will expect this level of legitimacy.
You'll also need an EIN (Employer Identification Number) from the IRS — free, and required once you hire staff or open a business bank account. Register for sales tax if your state taxes cleaning services (this varies — check your state department of revenue).
UK equivalent: register as a sole trader or set up a limited company via Companies House, register for VAT once turnover exceeds £90,000, and get PAYE set up if you hire employees.
Step 2: Get the right insurance
Commercial clients almost always require proof of insurance before signing. Standard requirements:
- General liability insurance — typically $1M–$2M coverage, expect to pay $500–$1,500/year depending on size.
- Workers' compensation — required in most states once you have employees.
- Janitorial bonding (fidelity bond) — protects clients against theft by your staff; many commercial RFPs explicitly ask for this. Costs $100–$500/year for modest coverage.
UK note: public liability insurance (£1M–£5M cover) plus employers' liability insurance (legally required if you have staff) are the equivalents.
Step 3: Price for commercial contracts
Janitorial pricing is usually done per square foot per month, not hourly, because clients want a predictable monthly invoice. Typical US ranges:
| Facility type | Price per sq ft/month (US) | Price per sq ft/month (UK, £) |
|---|---|---|
| Small office | $0.08 – $0.15 | £0.06 – £0.12 |
| Retail store | $0.10 – $0.20 | £0.08 – £0.16 |
| Medical/dental office | $0.15 – $0.30 | £0.12 – £0.24 |
| Warehouse/industrial | $0.05 – $0.10 | £0.04 – £0.08 |
Walk the space before quoting. Factor in frequency (nightly vs. 3x/week), number of restrooms, floor types (carpet vs. hard floor adds stripping/waxing costs), and whether trash removal or window cleaning is included. Always build a buffer for supplies and travel between sites.
Step 4: Equipment and supplies
Startup equipment costs for janitorial work are higher than residential because you're often cleaning larger, harder-wearing spaces:
- Commercial vacuum: $200–$600
- Floor buffer/scrubber (if offering floor care): $800–$3,000
- Mop buckets, microfiber systems, carts: $150–$400
- Commercial-grade cleaning chemicals and disinfectants: $100–$300/month depending on volume
- Branded uniforms and ID badges (many buildings require them for after-hours access): $200–$500
Budget $2,000–$5,000 to start a basic operation, more if you plan to offer floor stripping/waxing or carpet extraction as add-on services.
Step 5: Win your first contracts
Janitorial sales looks different from residential marketing. What actually works:
- Direct outreach to property managers — they control multiple buildings and can become repeat clients across properties.
- Bidding on RFPs — many businesses and government-adjacent facilities post janitorial RFPs; search local government procurement sites and commercial real estate listings.
- Networking with facility managers at local business associations or chambers of commerce.
- Referrals from vendors — HVAC companies, security firms, and landscapers often know which buildings need a janitorial provider.
Prepare a simple proposal template with your insurance certificate, references, pricing per sq ft, and a sample cleaning checklist — commercial clients decide faster when you make evaluation easy.
Step 6: Staffing and scheduling
Janitorial work usually happens outside business hours, which means you're managing a night-shift crew, key/access logistics, and quality checks without being on-site yourself. As you take on more buildings, you'll need:
- A system for assigning crews to sites and tracking which tasks were completed
- Time tracking for payroll and to prove hours billed match contract terms
- A way to invoice multiple recurring commercial clients on different billing cycles
This is where dedicated software pays for itself quickly. CleanWhale handles scheduling across multiple sites and crews, automates recurring invoicing for commercial contracts, and sends shift reminders so nothing gets missed on an unattended night shift.

Common mistakes to avoid
- Underpricing per-square-foot contracts — always walk the site first; quoting from photos or a floor plan alone leads to lost margin.
- Skipping the bond — losing an RFP because you lack fidelity bonding is common and avoidable.
- No backup staff — commercial clients expect service every scheduled night; a no-show with no backup crew can cost you the contract.
- Ignoring contract terms — read termination clauses and scope-of-work details carefully before signing; scope creep (extra tasks not in the original bid) erodes profit fast.
