Quick Answer: What should property managers look for in a janitorial vendor?

Property managers should vet janitorial vendors based on more than price. The right commercial cleaning partner should have proper insurance, trained employees, clear communication systems, safety protocols, quality control standards, reliable staffing, and experience with similar property types.

A cleaning vendor does not just affect how a building looks. They affect tenant satisfaction, liability exposure, building reputation, and how much time your property management team spends putting out fires.

If you are comparing janitorial companies, use this checklist before signing the contract.

Janitorial Vendor Checklist: What to Review Before Hiring

Not every cleaning company is the right fit for a professionally managed property. A reliable janitorial vendor should understand your building type, communicate clearly, and have systems in place to deliver consistent work.

Use this checklist before signing a new contract or renewing an existing one.

1. Confirm They Understand Your Property Type

A multi-tenant office building, dealership, medical office, retail center, and industrial facility all have different cleaning needs.

Ask:

• Have you worked with properties like ours before?
• How do you handle high-traffic areas?
• What areas typically need the most attention?
• Can you support both nightly cleaning and day porter services?

A strong vendor should ask questions about your property before giving a quote. They should want to understand your square footage, restroom count, flooring types, tenant needs, traffic patterns, and service expectations.

Red flag: They give you a price before learning about the building.

2. Review Employee Training and Supervision

Training is one of the biggest differences between a basic cleaning crew and a professional janitorial partner.

Ask:

• Are cleaners employees or contractors?
• How are team members trained?
• Who supervises the work?
• How do you handle call-outs or absences?
• Are staff trained on chemicals, equipment, and site-specific procedures?

According to OSHA’s cleaning industry guidance, cleaning workers may face risks related to chemicals, equipment, lifting, and workplace hazards. That makes proper training and supervision essential.

For property managers, this also means fewer missed tasks, fewer safety concerns, and more consistent service.

3. Verify Insurance and Compliance

Your janitorial vendor should be able to provide documentation quickly and clearly.

Confirm they have:

• General liability insurance
• Workers’ compensation coverage
• Business license
• Safety procedures
• Chemical Safety Data Sheet access
• Clear emergency contact information

A vendor working inside your property may have after-hours access, use cleaning chemicals, move equipment, mop floors, and handle trash removal. Proper coverage and documentation protect both the vendor and the property.

Red flag: They cannot provide insurance or safety documentation when asked.

4. Ask What Products They Use

Cleaning products matter. They affect indoor air quality, surface protection, tenant comfort, and sustainability goals.

Ask:

• What products do you use?
• Are products safe for our surfaces?
• Do you offer environmentally preferable options?
• Are staff trained not to mix chemicals?
• Do you keep Safety Data Sheets available?

The EPA Safer Choice program helps identify cleaning products made with ingredients that are safer for people and the environment. This can be especially important for properties with ESG goals, sensitive occupants, or sustainability standards.

5. Make Sure the Scope of Work Is Clear

A vague scope creates vague results. Before hiring a janitorial vendor, make sure the proposal clearly explains what is included and how often each task will be completed.

Your scope should address:

• Restroom cleaning and restocking
• Trash and recycling removal
• Lobby and common area cleaning
• Breakroom or kitchen cleaning
• Elevator and stairwell cleaning
• Glass and entrance cleaning
• High-touch surface cleaning
• Floor care
• Carpet care
• Day porter responsibilities, if needed

Red flag: The proposal only says “general cleaning” without task details or frequency.

6. Evaluate Communication Standards

For property managers, communication can be just as important as cleaning quality.

Ask:

• Who is our main point of contact?
• How quickly do you respond to issues?
• How are tenant complaints handled?
• Do you provide inspection updates?
• How do cleaners report issues they notice onsite?
• What is the escalation process?

A good janitorial vendor should reduce the number of cleaning-related problems landing on your desk. They should communicate proactively, not only when something goes wrong.

7. Check Their Quality Control Process

Every vendor says they provide quality service. The better question is how they verify it.

Ask:

• Are inspections completed regularly?
• Who checks the work?
• Is there a property-specific checklist?
• How are missed tasks corrected?
• Do you track recurring issues?
• Can the scope be adjusted as needs change?

A strong quality control process helps catch issues before tenants, customers, or building visitors notice them.

8. Confirm Safety Procedures

Cleaning should improve the safety of your property, not create new risks.

Ask whether staff are trained on:

• Wet floor signs
• Chemical handling
• Equipment use
• Proper lifting
• Spill response
• Personal protective equipment
• Secure building access

The CDC’s facility cleaning and disinfecting guidance recommends following product label directions and cleaning surfaces appropriately based on use and risk. A professional cleaning vendor should understand when cleaning, sanitizing, or disinfecting is needed.

9. Compare More Than Price

The lowest bid is not always the best value. A cheaper janitorial vendor may cost more over time if your team has to manage tenant complaints, missed tasks, poor communication, or re-cleaning.

When comparing vendors, look at:

• Experience
• Staffing
• Training
• Insurance
• Communication
• Quality control
• Safety procedures
• Flexibility
• Day porter availability
• Special project support

The right vendor should make your property easier to manage, not harder.

Key Questions for Your Janitorial Vendor Checklist

Before choosing a cleaning company, ask:

• What types of properties do you specialize in?
• Are your cleaners employees or contractors?
• How are team members trained?
• Who supervises the work?
• What insurance coverage do you carry?
• What products do you use?
• How do you handle complaints?
• How do you handle missed tasks?
• Can you provide day porter services?
• Can you support special projects?
• What makes your company different?

Their answers will help you understand whether they are a true partner or just another vendor.
