How to Hire a Janitorial Company: Evaluation Criteria and Process

Hiring a janitorial company is a structured procurement decision that carries regulatory, financial, and operational consequences for any facility. The evaluation process spans vendor licensing verification, insurance confirmation, staffing practices, scope-of-work definition, and contract structure — not price alone. This page covers each stage of that process, defines the criteria that separate qualified vendors from inadequate ones, and identifies the decision boundaries that determine which type of vendor fits which facility type.

Definition and scope

The hiring process for a janitorial company is a formal procurement activity through which a facility owner, property manager, or procurement officer selects a professional cleaning vendor, defines service expectations through a documented scope of work, and executes a binding service agreement. The process applies across commercial offices, retail spaces, industrial facilities, schools, government buildings, and medical properties — each of which carries distinct regulatory obligations and operational requirements.

The scope of "hiring" includes both initial vendor selection and recurring contract renewal assessments. A vendor that met minimum thresholds at original hire may no longer satisfy updated OSHA compliance requirements, current insurance minimums, or facility-specific mandates such as green cleaning or healthcare disinfection protocols. Renewal evaluation should apply the same criteria used in initial procurement, not a reduced set.

Understanding the distinction between janitorial services and commercial cleaning is essential at the scoping stage. Janitorial work refers to recurring, scheduled maintenance — trash removal, restroom sanitation, floor mopping, and surface wiping. Commercial cleaning may encompass periodic deep-cleaning and specialty project services. A vendor capable of both categories warrants a different contract structure than one delivering only routine maintenance.

How it works

The hiring process moves through 5 discrete stages, each building on outputs from the previous step.

Facility assessment and scope definition — Before contacting any vendor, the facility manager documents the building's square footage, surface types, occupancy schedule, regulated areas (e.g., medical waste zones, food-prep spaces), and required service frequency. This becomes the basis for a janitorial service request for proposal.
Vendor identification and pre-qualification — Candidates are sourced through the cleaning services directory or industry referrals. Pre-qualification screens for active business licensure, general liability insurance (most commercial properties require a minimum of $1,000,000 per occurrence, though the specific threshold depends on the facility type and lease terms), and workers' compensation coverage. Details on coverage thresholds appear in the janitorial company licensing and insurance guide.
Proposal evaluation — Qualified vendors submit written proposals against the RFP. Evaluation criteria include: task-level scope alignment, staffing ratios per square foot, cleaning product specifications (particularly for facilities requiring green janitorial services or regulated disinfectants), equipment inventories per the janitorial equipment types and uses classification, and pricing structure. The janitorial service pricing guide provides benchmark context for assessing whether bids reflect market rates or contain unexplained variances.
Background check and staffing verification — Any vendor awarded access to a secured or regulated facility must demonstrate a defined staff vetting and background check protocol. This includes criminal history screening, employment eligibility verification, and, for healthcare or school environments, additional credential checks aligned with sector-specific requirements.
Contract execution — The final stage produces a written janitorial service contract specifying service frequency, task lists, quality audit mechanisms, termination clauses, and dispute resolution procedures. Verbal agreements or informal email exchanges do not constitute enforceable scopes and create dispute risk.

Common scenarios

Office buildings — Standard procurement for an office facility prioritizes daytime versus nighttime scheduling decisions, floor care protocols aligned with carpet or hard-surface ratios, and restroom sanitation standards. Office janitorial services contracts typically run 12 months with 30-day termination notice clauses.

Medical and healthcare facilities — Medical facility janitorial services require vendors with documented training in bloodborne pathogen handling per OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030), EPA-registered disinfectant use, and waste segregation procedures. Hiring criteria here are non-negotiable and regulatory rather than preference-based.

Schools and educational facilities — School janitorial services involve mandatory background check requirements that vary by state, daytime custodial presence for spill response, and often Green Seal or EPA Safer Choice product requirements under district sustainability policies.

Retail and warehouse environments — Retail janitorial services emphasize high-traffic floor care and restroom frequency tied to customer volume. Warehouse janitorial services introduce industrial floor equipment, dust control, and loading dock sanitation as distinct scope elements not present in office contracts.

Multi-tenant commercial properties — Janitorial services for multi-tenant buildings create a split-authority structure where the property manager holds the master contract but individual tenants may have supplemental agreements. Scope boundaries between common areas and tenant suites must be explicitly defined in the master contract to avoid service gaps.

Decision boundaries

Franchise versus independent company — The franchise versus independent janitorial company distinction affects quality control infrastructure, insurance backing, and workforce stability. Franchise operators typically carry standardized training programs and corporate insurance umbrella coverage; independent companies may offer greater schedule flexibility and direct management accountability. Neither model is categorically superior — the facility type and contract complexity determine which fits.

In-house versus outsourced — The in-house versus outsourced janitorial services decision hinges on three factors: labor cost structure, management bandwidth, and regulatory exposure. Outsourcing transfers workers' compensation liability and OSHA compliance responsibility to the vendor, which is a meaningful risk-transfer for facilities with high-traffic or hazardous environments. In-house models give direct supervisory control but require the facility to carry full employer obligations.

Certifications as qualifying criteria — Janitorial industry associations and certifications such as ISSA's Cleaning Industry Management Standard (CIMS) certification or the BSCAI (Building Service Contractors Association International) membership provide third-party verification of operational and ethical standards. Requiring CIMS certification as a minimum threshold in an RFP narrows the vendor pool but filters for documented quality management systems.

Quality audit requirements — Contracts must specify measurable janitorial service quality control mechanisms: inspection frequency, scoring rubrics, escalation paths for failed audits, and performance cure periods before termination rights activate. A contract that lacks a quality audit clause provides no enforceable remedy for substandard performance short of full contract termination.

When a vendor relationship deteriorates despite contractual protections, the janitorial service complaints and dispute resolution process governs the escalation path — from written notice through mediation and, if necessary, regulatory or civil recourse.
