Choosing a Janitorial Partner: Questions Property Managers Should Ask

Protect reputation, occupant health, and building value

A single cleaning contract can shape your building's reputation, occupant health, and long-term maintenance costs.

Poor choices raise liability, increase downtime, and accelerate floor and asset wear.

In this guide we explain which credentials to verify, from ISSA CIMS to GBAC STAR.

You'll also learn how to confirm insurance and OSHA-based training.

We'll cover technical certifications such as IICRC for advanced floor and carpet care.

Then we'll walk through evaluating quality assurance, communication, staffing, specialized services, and continuity planning.

Expect practical, research-backed questions you can use when vetting vendors.

Verify the right credentials and insurance before you sign

Want a cleaning partner who actually reduces your liability and keeps your building safe?

Start by separating company-level credentials from technician-level credentials. Company certifications show management systems and quality controls. ISSA CIMS is the industry benchmark for that, and it requires third-party audit recertification about every two years.

Company and technician credentials that matter

For infection prevention, ask about GBAC STAR accreditation. GBAC STAR proves a company follows biorisk and infection-prevention protocols.

For technical work, request IICRC or other surface‑care certifications for carpet and hard floors. And confirm OSHA-based training for staff, including Bloodborne Pathogens training when the work requires it.

Insurance, bonds, and practical verification steps

Insist on current proof of general liability insurance. General liability protects you from third-party injury and property damage during service.

Confirm workers' compensation is active for all employees. Workers' comp shields you from employee injury claims in most jurisdictions. Also ask for a janitorial surety bond to protect against theft or dishonest acts.

Request physical certificates and verify them through issuing organizations or public registries. Keep copies with your contract and check recertification dates during annual reviews.

How to specify bonding & insurance in janitorial RFPs

• Can you provide a current ISSA CIMS certificate and the date of the last third-party audit?
• Are you GBAC STAR accredited for biorisk management, and can you show the active accreditation?
• Do your on-site technicians have OSHA training and Bloodborne Pathogens certification when relevant?
• Can you produce IICRC or equivalent certificates for staff who perform carpet and specialty floor work?
• Please provide a current certificate of general liability insurance with policy limits and effective dates.
• Do you carry workers' compensation for all employees who will work on-site, and can you show proof?
• Are you bonded for janitorial services? Please provide the surety bond document and bond number.
• How do you demonstrate ongoing compliance? Ask about recertification schedules, supervisor audits, and registry listings.

We recommend collecting physical documents before finalizing a contract. Verify them now so you avoid gaps later and protect your building, occupants, and reputation.

Make quality measurable: what a strong QA program should deliver

Want consistent cleaning that you can verify each month and report on to stakeholders?

We recommend evaluating a vendor by the systems they use, not just how clean the place looks during a walkthrough.

What a robust QA program looks like

Ask whether the vendor has written standard operating procedures for every zone and task.

Look for digital mobile checklists with consistent scoring so inspections are objective and repeatable.

Industry guidance recommends weekly inspections during onboarding, then monthly checks once performance stabilizes.

Track the right KPIs and verify corrective actions

Request specific KPIs such as inspection scores, response and resolution times, corrective-action closure rates, task completion, and complaint trends.

Targets matter: Class A sites generally aim for 90-plus inspection scores, and Class B sites for about 85 and up.

Expect urgent responses under two hours and a corrective-action closure rate near 95 percent within 30 days.

Communication, references, and proof you can trust

Strong partners use a daily facility journal or digital log, scheduled touchpoints, clear escalation paths, and supervisor on-site access.

When you call references, ask targeted questions about responsiveness, staff consistency, communication methods, and handling of specialized requirements.

• Can you describe a time a cleaning issue came up and how quickly the vendor fixed it?
• Has the same crew worked here consistently, or has turnover caused problems?
• What communication tools do you use with the vendor, and do they give you clear, timestamped records?
• Did the vendor meet specialized needs like medical-grade disinfection or off-hours scheduling?
• Have there been any security or access concerns while they worked on-site?

For a practical way to compare bidders, see our vendor scorecard and contract-audit guide for KPIs and SLA language at Cleaning Concepts' vendor scorecard and contract audit guide.

Bottom line: demand documented processes, measurable KPIs, and verifiable references before you sign.

Ensure consistent coverage and protect your assets

Worried about inconsistent crews, damaged floors, or missed cleanings that hurt your reputation?

Start by confirming how a vendor hires, trains, and retains staff. Reliable programs reduce security risks and service gaps.

Staffing, training, and continuity you should verify

Ask whether cleaners are W-2 employees or 1099 subcontractors. W-2 employment gives more control over training, accountability, and security.

Request proof of thorough background checks, identity verification, and reference screening. These steps protect your facility and occupants.

Confirm the vendor’s approach to turnover. Look for competitive pay, promotion pathways, and ongoing training to keep crews consistent.

Operational flexibility, contingency, and communication

• Are your on-site cleaners W-2 employees or 1099 subcontractors?
• What background-screening steps do you perform and can you provide documentation?
• What is your average annual turnover rate for the team assigned to our account?
• How do you customize cleaning hours around our peak operations and patient-care windows?
• What is your formal contingency plan for an absent cleaner, and how fast can you deploy trained backup staff?
• How do you handle seasonal surges or outbreak-driven demand and what enhanced-disinfection protocols do you use?
• What communication tools do you provide, such as a daily facility journal or digital logs, for real-time feedback?

Floor care, post-construction, and supply transparency

Require a documented floor maintenance plan that separates daily care, interim care, and restorative deep work. Restorative work should be scheduled by wear, not fixed dates.

For post-construction, expect three phases: rough clean, light/detail clean, and touch-up clean. Ask for an itemized checklist and HEPA vacuum use.

Insist on Safety Data Sheets for all chemicals, disclosure of VOC content, and documented green-cleaning options for sensitive spaces.

Bottom line: use these focused questions to reveal whether a bidder can protect your people, minimize disruption, and extend asset life.

Turn questions into verifiable commitments

Want to turn vendor claims into verifiable commitments? Focus on three vetting areas: credentials and insurance, QA and communication, and operations plus specialty capabilities.

Ask for references, documented KPIs, and a detailed scope of work so promises become measurable obligations. Use inspection reports, service logs, and a vendor scorecard to confirm performance before you sign.
