Janitorial contracts are notoriously vague—what one company calls "comprehensive cleaning" another company considers a basic sweep and mop. Knowing what's actually included (and what costs extra) saves you thousands in hidden fees and prevents awkward conversations when your office still looks dirty after the service shows up.
This guide breaks down the real components of janitorial contracts so you can compare apples to apples and hire a service that actually meets your needs.
Standard Daily/Weekly Cleaning Tasks
Most janitorial contracts include routine floor maintenance, trash removal, and restroom cleaning. However, the depth varies wildly between providers.
Typical included services cover:
- Vacuuming carpeted areas and sweeping hard floors
- Emptying trash and recycling bins
- Wiping down sinks, toilets, and urinals in bathrooms
- Cleaning mirrors and dispensers
- Mopping high-traffic areas (usually with basic detergent)
- Dusting desks, tables, and common surfaces
- Restocking paper towels and toilet paper
The frequency matters more than you'd think. A service that vacuums twice weekly will prevent dirt accumulation better than one that does it once. Before signing, confirm whether your contract specifies daily, three-times-weekly, or weekly service—and ask when (overnight, early morning, mid-afternoon).
What Usually Costs Extra
This is where contracts get expensive fast. Always clarify these line items before committing:
- Deep cleaning or strip-and-wax flooring: $3–$8 per square foot, typically quarterly or semi-annually
- Carpet shampooing: $0.15–$0.35 per square foot, often done annually
- Window cleaning: $1–$3 per window for exterior, double for interior-and-exterior
- Pressure washing: $0.10–$0.50 per square foot depending on surface type
- HVAC vent and duct cleaning: $300–$800 per building, yearly
- Specialty surface polishing: $2–$6 per square foot for tile, stone, or hardwood
- Graffiti or stain removal: Quoted case-by-case, sometimes charged hourly at $50–$100
A 5,000 square-foot office building with quarterly deep cleaning could easily add $2,000–$4,000 annually to your base janitorial contract.
Frequency and Scope Tiers
Janitorial companies typically offer tiered service levels, much like subscription plans. Understanding these tiers prevents overpaying for services you don't need.
Basic Tier ($400–$800/month for a 3,000 sq ft space): Daily trash removal, twice-weekly vacuuming, bathroom restocking, light surface wiping.
Standard Tier ($800–$1,500/month): Daily vacuuming and mopping, five-times-weekly bathroom deep-clean, daily trash, kitchen appliance wiping, weekly window sills.
Premium Tier ($1,500–$2,500+/month): Nightly deep cleaning, daily bathroom sanitization, weekly window cleaning, monthly carpet spot-cleaning, restroom graffiti/stain treatment included.
Your actual needs depend on foot traffic, industry (healthcare and food service need more frequent sanitizing), and whether employees eat on-site.
Contract Length and Pricing Strategies
Janitorial companies usually offer contracts ranging from month-to-month to three years. Here's what to expect:
- Month-to-month: 10–15% premium on pricing, flexibility if service quality drops
- 12-month contract: 5–8% discount, minimal early-exit penalties often included
- 3-year contract: 10–20% discount, but locked rates—ask about escalation clauses (annual price increase caps)
Request quotes for both a 12-month and 3-year term. Sometimes the per-month savings don't justify losing flexibility, especially if you're unsure about building expansion or relocation.
Red Flags in Contracts
Before signing, watch for these problem areas:
- Vague cleaning standards: "Maintain cleanliness" is not a contract. Demand specific tasks and frequencies.
- No service level agreement (SLA): Will they respond to complaints same-day? What's the penalty for missed services?
- Hidden scheduling clauses: Can they change service times without notice? Are after-hours services charged differently?
- Automatic renewal without notice: Some contracts auto-renew unless you cancel 30–60 days prior.
Comparing and Hiring
When evaluating providers, get itemized quotes specifying each task, frequency, and pricing for add-ons. Mercoly helps you compare trusted janitorial services in one place, so you're not cobbling together fragmented information from five different websites.
Request references from current clients with similar building sizes and industries. A company's experience cleaning a medical office differs significantly from office parks or retail spaces.
Frequently Asked Questions
Q: What's the difference between janitorial and commercial cleaning services? Janitorial services handle routine daily/weekly maintenance, while commercial cleaning typically refers to larger projects like carpet cleaning, floor refinishing, or one-time deep cleans. Many providers offer both.
Q: Should I negotiate pricing if I sign a multi-year contract? Yes. Most companies expect negotiation on 2–3 year contracts. Request 12–15% discounts for longer commitments, especially if you're bundling multiple services.
Q: What happens if the cleaning quality drops mid-contract? This depends on your SLA. Ensure your contract specifies complaint procedures, response timelines, and remedies (service credit, replacement cleaning, or termination without penalty).
