How to Evaluate Your Commercial Cleaning Company’s Performance

Most businesses never formally evaluate their cleaning company. They notice when things are bad, complaints from staff, visible problems in client-facing areas, but they don’t have a structured way to measure whether the service is actually delivering what they’re paying for.

That’s a problem. Without a baseline and a review process, you’re either overpaying for inconsistent service or missing warning signs until the situation is bad enough to force a change.

Here’s a practical approach to evaluating your cleaning vendor, one you can put into practice whether you’ve had your current company for six months or six years.

What to Inspect and How Often

Good evaluation starts with knowing what to look at. Different areas warrant different inspection frequencies.

High-Touch and High-Traffic Areas (Inspect Every Visit)

These are the spaces where failure is most visible, and most damaging to employee and client perception:

• Restrooms: Stalls wiped down, toilets and sinks sanitized, mirrors clean, supplies restocked (paper towels, toilet paper, soap)
• Entrances and lobbies: Floors clean and dry, glass wiped, mats vacuumed or shaken
• Break rooms and kitchens: Surfaces wiped, sink clean, trash emptied, microwave exterior clean
• High-touch touchpoints: Light switches, door handles, elevator buttons, shared equipment

General Work Areas (Inspect Weekly)

• Desks and workstations: Surfaces dusted, trash emptied
• Floors: Vacuumed, mopped, or swept as appropriate, no visible debris or staining
• Conference rooms: Chairs pushed in, whiteboard ledges cleaned, glass surfaces wiped

Periodic Areas (Inspect Monthly)

• Baseboards and vents: Dust accumulation
• Window interiors: Fingerprints, streaks, visible grime
• Supply closets: Organized, restocked, equipment properly stored
• Stairwells and hallways: Floors and walls, particularly in corners and along edges

A Simple Scoring System

You don’t need sophisticated software to evaluate cleaning quality. A simple five-point scale works well:

Rate each area or task, then calculate an average. Over time, track these scores month over month.

General benchmarks:

• 4.0 or above: Your cleaning program is performing well. Share the positive feedback, it reinforces good work.
• 3.0–3.9: Some areas need attention. Schedule a check-in with your account manager.
• Below 3.0: Significant quality issues exist. Escalate formally with documentation.

How to Give Feedback That Actually Works

A lot of vendor feedback lands poorly, either it’s too vague to act on, or it puts the company on the defensive. Here’s how to make it useful.

Be specific and documented. “The bathrooms are sometimes not clean” is hard to act on. “Restroom 2B had visible mineral buildup around the sink drain on three consecutive Tuesdays” is actionable. Photos are even better.

Report through the right channel. Use whatever communication method your contract specifies, usually email to an account manager, not a text to a crew member. A paper trail matters.

State what you need, not just what went wrong. “This wasn’t done correctly” is a complaint. “We need this addressed at the next scheduled visit and confirmed via the inspection log” is a request that produces results.

Track your reports. Keep a simple log of what you reported, when, and how it was resolved. This protects you if problems become chronic and you need to make a case for contract termination.

How to Conduct a Formal Performance Review

For ongoing relationships, a formal quarterly review keeps the relationship on track and gives both parties a chance to recalibrate.

Before the meeting:

• Complete a full inspection walk-through using your scorecard
• Compile any complaint logs or unresolved issues from the quarter
• Note any changes to your facility or schedule coming up

During the meeting:

• Share your scorecard findings, both positives and deficiencies
• Review any unresolved issues and get a timeline for correction
• Discuss any upcoming needs (seasonal deep cleaning, schedule adjustments, new areas)
• Confirm the right contacts on both sides

After the meeting:

• Send a brief written summary of what was discussed and agreed upon
• Set a date for the next review

This doesn’t need to be formal or lengthy. A 30-minute walk-through followed by a quick email summary is enough. What matters is that it happens consistently.

When to Escalate vs. When to Walk Away

Not every problem means it’s time to end the relationship. Here’s a practical framework.

Escalate (Don’t Leave Yet) When:

• Problems are isolated to specific tasks or areas, not systemic
• The company acknowledges the issue and responds within 24–48 hours
• There’s a clear corrective action with a follow-up timeline
• The relationship is otherwise strong and you’ve seen improvement over time

How to escalate: Put it in writing. Describe the specific issue, how many times it’s occurred, and what resolution you expect and by when. Ask for a response within 48 hours.

Consider Walking Away When:

• The same problem recurs after multiple documented complaints
• The company is unresponsive or dismissive when you raise issues
• Quality has declined steadily over 60–90 days with no turnaround
• Staff turnover on your account is so high that no one knows your facility
• There’s a serious incident, theft, property damage, breach of access, that isn’t handled properly

Before terminating, review your contract’s termination clause. Most allow exit for cause with documented evidence of repeated non-performance. If you’ve been keeping records, you’re already in a strong position.

Setting Performance Expectations in the Contract

The most effective evaluation starts before the relationship begins. Performance standards written into the contract give you an objective baseline to measure against, and legal standing if the company fails to meet them.

Before you sign, ask that the contract include:

• Specific task definitions tied to each area, not generic language
• A complaint response timeline (typically 24–48 hours)
• A make-up visit policy when tasks are missed
• A formal QC inspection schedule from the vendor side
• A scorecard or checklist format for documented inspections

This puts both parties on the same page from day one, and removes any ambiguity about what “clean” actually means for your facility.

FAQ

How often should I formally evaluate my cleaning company?

Monthly inspections with a quick scorecard are ideal for the first six months of a new relationship. Once you’ve established trust and consistency, quarterly formal reviews are typically sufficient, with informal check-ins as needed.

What’s the best way to document cleaning problems?

A timestamped photo paired with a brief written description is the most effective documentation. Keep a running log, even a simple spreadsheet with date, issue, area, and resolution status, so you can identify patterns and have a record if things escalate.

Should I tell the cleaning company when I’m doing an inspection?

It depends on what you’re trying to learn. Announced inspections let you review results together and have a real-time conversation. Unannounced inspections give you a more accurate picture of everyday performance. The best practice is a mix of both.

What score should trigger a formal complaint?

Any area scoring a 2 or below warrants a formal written complaint. A pattern of 3s across multiple areas, even if none hit “critical”, is worth raising in a scheduled review. Don’t wait until things are at 1 to say something.

Is it normal for cleaning quality to decline over time?

Some variation is normal, especially with staff transitions or seasonal demands. A gradual, sustained decline, month over month, across multiple areas, is not normal and usually reflects a management or staffing problem at the vendor level. Raise it early; it rarely self-corrects.

When is the right time to switch cleaning companies?

When documented problems persist after multiple formal complaints, when the company is unresponsive to escalation, or when the relationship has degraded to the point where you’re spending more time managing the vendor than running your business. A good cleaning company should make your facility better, not give you another thing to chase.
