Is in-house cleaning actually cheaper? Here is the real cost breakdown of hiring employees vs. hiring a commercial cleaning contractor.
Facility managers often assume in-house cleaning is cheaper because staff wages look lower than a contractor’s invoice. But the full picture includes payroll taxes, workers’ comp, insurance, equipment, supplies, training, and management overhead. This breakdown reveals the true cost of each model.
Facility managers often assume in-house cleaning is cheaper because staff wages look lower than a contractor monthly invoice. But that comparison misses the full picture. When you add payroll taxes, workers compensation insurance, health benefits, equipment, supplies, training, management overhead, and replacement costs for turnover, the in-house model often ends up costing more than outsourcing.
A thorough cost comparison requires looking at direct costs, hidden costs, opportunity costs, and qualitative factors like service quality and risk. This breakdown gives you the full financial picture so you can make an informed decision based on total cost of ownership — not just the line item that appears on a budget spreadsheet.
The Direct Costs of In-House Cleaning
Wages: Janitorial staff $12-$18/hr. Payroll taxes and benefits add 15-25% (FICA 7.65%, workers’ comp 2-5%, health insurance if offered). Supplies: $0.10-$0.25/sq ft/year for chemicals, paper goods, trash bags. Equipment: Vacuums $300-$800 each, floor machines $1,500-$4,000, carpet extractors $2,000-$5,000. Uniforms: $200-$400/year per employee. Training: OSHA compliance, chemical handling, equipment use. Management: Supervisory time, scheduling, quality control. Total in-house: $0.15-$0.30/sq ft/month.
Wages: Janitorial staff typically earn $12-$18 per hour depending on location and experience. For a 2-hour nightly shift, that is $120-$180 per week per employee, or $6,240-$9,360 per year per employee before any additional costs.
Payroll taxes and benefits add 15-25%: FICA (Social Security and Medicare) adds 7.65%, workers compensation insurance adds 2-5% depending on the classification code, unemployment insurance adds 2-6%, and health insurance adds $400-$800 per month per employee if offered.
Supplies: $0.10-$0.25 per square foot per year for chemicals, paper goods, trash bags, and consumables. For a 50,000 sq ft building, that is $5,000-$12,500 annually.
Equipment: Commercial vacuums $300-$800 each, auto scrubbers $3,000-$15,000, floor buffers $1,500-$4,000, carpet extractors $2,000-$5,000, and various hand tools and supplies.
Training and uniforms: OSHA compliance training, chemical handling training, equipment operation training, and branded uniforms at $200-$400 per employee per year.
Total in-house cost: $0.15-$0.30 per square foot per month when all costs are included.

What’s extra: Floor stripping/waxing $0.50-$1.00/sq ft, carpet cleaning $0.15-$0.50/sq ft, window washing $2-$8 per pane, construction clean up: variable. Total outsourced: $0.10-$0.25/sq ft/month base, plus periodic services.
Contract price: Standard full-service janitorial contracts range from $0.10-$0.25 per square foot per month. For a 50,000 sq ft building, that is $5,000-$12,500 per month.
What is included: The contract price covers labor, all cleaning supplies and chemicals, all equipment and maintenance, general liability and workers comp insurance, supervision and quality control, account management, and backup staffing for absences.
What is extra: Periodic services are typically priced separately: floor stripping and waxing $0.50-$1.00 per square foot, carpet cleaning $0.15-$0.50 per square foot, window washing $2-$8 per pane, construction cleanup variable by scope, and pressure washing $0.15-$0.50 per square foot.
Total typical outsourced cost: $0.12-$0.28 per square foot per month including periodic services spread over the contract term.
Hidden Costs in the In-House Model
In-house costs many facility managers overlook: Recruitment and turnover: Janitorial turnover averages 200-400% annually. Substitute coverage: When staff call in sick, someone covers or the work doesn’t get done. Equipment repair and replacement: Unexpected breakdowns. Liability: Slip-and-fall claims, equipment damage, chemical misuse. Compliance: OSHA recordkeeping, safety training documentation, labor law compliance. Supply chain: Running out of supplies, storage costs, ordering time. For compliance details, see full-service janitorial coverage guide.
Many facility managers overlook these in-house costs:
Recruitment and turnover: Janitorial industry turnover averages 200-400% annually. Each time an employee leaves, you pay for recruiting, interviewing, background checks, drug testing, and training. Replacement costs average $1,000-$3,000 per employee.
Coverage for absences: When an in-house employee calls in sick, someone else must cover the shift — either another employee working overtime or a manager doing the cleaning. Both options add cost and reduce quality.
Equipment repair and replacement: Commercial cleaning equipment breaks down. Repairs are unexpected expenses, and replacement cycles add to long-term costs.
Liability risk: Slip-and-fall claims, chemical misuse, equipment damage — these liabilities fall on the building owner with an in-house crew. A single claim can wipe out years of perceived savings.
Compliance burden: OSHA recordkeeping, safety training documentation, labor law compliance, I-9 verification, and ongoing HR administration all require management time and attention.
Service Quality Comparison
Professional contractors provide trained, insured staff with supervision and quality assurance. Benefits include: Consistency: Scheduled inspections and follow-up. Specialized equipment: Commercial-grade that in-house budgets often skip. Flexibility: Adjust scope for special events. Depth: Backup staff for absences. Insurance: General liability typically $1M-$2M. Certifications: ISSA CIMS, Green Seal, OSHA training. For audits, see our guide on healthcare facility compliance.
Beyond cost, service quality differs significantly between the two models:
Consistency: Professional contractors have established quality control systems, inspection protocols, and account management structures that are difficult for in-house operations to replicate. They conduct regular inspections and follow up on deficiencies.
Equipment: Contractors invest in commercial-grade equipment that in-house budgets often skip. HEPA-filtered vacuums, auto scrubbers, and carpet extractors produce noticeably better results than consumer-grade equipment.
Flexibility: Contractors can scale up for special events, add services like carpet cleaning or window washing, and adjust scope as needs change. In-house crews require hiring additional staff or paying overtime.
Insurance coverage: Professional contractors carry general liability of $2M-$4M, workers compensation, and bonding. This shifts risk away from the building owner. In-house operations leave the owner exposed to employment-related claims.
When In-House Makes Sense
In-house works best for: Single-location: One facility under 50,000 sq ft with consistent needs. Specialized environments: Unique requirements contractors can’t easily staff. 24/7 operations: Manufacturing shifts requiring constant presence. Budget certainty: Direct control over labor costs with no contract escalators.
In-house cleaning works best in specific situations. Consider it when: you have a single facility under 50,000 square feet with consistent cleaning needs; your facility operates 24/7 and requires cleaning staff on-site at all times; you have specialized cleaning requirements that contractors cannot easily staff; or you need tight control over cleaning schedules and access for security-sensitive environments.
Even in these cases, a hybrid model often works better — hiring a contractor for periodic deep cleaning, carpet extraction, and floor care while keeping a small in-house crew for daily maintenance.
When Outsourced Makes Sense
Outsourcing wins for: Multi-site operations: Consistent quality across locations. Larger facilities: Over 50,000 sq ft where contractors’ efficiency scales. Complex needs: Multiple surface types, specialized cleaning, regulatory requirements. Cost control: Predictable monthly invoice with no surprise expenses. Lower risk: Contractor carries insurance and liability. See cost per square foot guide and janitorial service overview plus sample proposals.
Outsourcing wins in most commercial scenarios. It is the better choice when: you manage multiple buildings or a portfolio where consistency matters; your facility exceeds 50,000 square feet and contractors efficiency scales with size; you have complex cleaning needs like healthcare, education, or food service with regulatory requirements; you want predictable monthly costs without surprise expenses for equipment repairs or staff turnover; or you want to transfer liability and compliance burden to a professional company.
For multi-site property managers, outsourcing provides consistent quality across locations with a single point of accountability. See cost per square foot guide and janitorial service overview plus sample proposals.

For most commercial buildings over 50,000 square feet, outsourcing to a professional cleaning contractor saves money, reduces risk, and delivers higher quality than an in-house operation. The apparent cost advantage of in-house cleaning is an illusion created by comparing wages to contract prices without accounting for all the hidden costs of employment.
