Why cleaning and janitorial vendors are hard to evaluate
Of all the vendors in a facility manager's portfolio, cleaning and janitorial vendors are among the hardest to evaluate objectively. A well-structured cleaning vendor scorecard is the best tool for creating that objectivity. The work is frequent, distributed across your entire facility, and largely invisible when it's done well. Problems only become visible when something is clearly wrong, and by then, the issue has usually been building for some time.
The result is that cleaning vendor performance often gets evaluated on feelings rather than facts. A space "seems clean." A vendor "seems reliable." But when it comes to contract renewal or a performance conversation, that subjective impression doesn't hold up.
This article covers the metrics that actually matter for cleaning and janitorial vendor performance, and the five most common signs that a vendor is underperforming, before it becomes a serious problem.
The core metrics for cleaning and janitorial performance
Effective evaluation of a cleaning or janitorial vendor requires metrics that can be measured consistently, regardless of who is doing the assessment.
Inspection scores. Structured site inspections, scored against a defined standard, are the most reliable indicator of cleaning quality. Scores should cover multiple zones or areas within your facility and be recorded at each inspection. Over time, inspection scores reveal trends: is quality improving, declining, or static?
Schedule adherence. Is the cleaning completed at the agreed times? Frequency compliance, whether daily, weekly, or task-specific cleaning is completed as contracted, is a basic but often overlooked metric. A vendor completing 70% of scheduled tasks is underperforming regardless of how good the work is when it does happen.
Response time for reactive requests. When a spill, incident, or urgent cleaning need arises, how quickly does the vendor respond? Track response times against the agreed SLA and look at both the average and the outliers.
Complaint rate. Track complaints from building occupants, tenants, or staff separately from your own inspection results. A low complaint rate doesn't guarantee quality, but a rising complaint rate is almost always a leading indicator of a performance problem.
Restocking compliance. For janitorial work that includes consumables management, soap dispensers, paper products, hygiene supplies, track whether restocking is completed as required. This is frequently the first area to slip when a vendor is stretched thin.
Janitorial-specific metrics worth tracking separately
Janitorial work, the day-to-day operational side of facility cleaning, has some specific metrics that warrant separate tracking.
First-shift readiness. Are facilities ready for occupancy at the agreed start time? Restrooms stocked, floors clean, entry areas presentable? This is a binary, time-stamped metric that's easy to document.
Waste removal compliance. Are bins emptied on schedule? Is waste sorted correctly where required? Missed waste collections create hygiene and regulatory issues quickly.
Equipment condition. Is the vendor's cleaning equipment maintained to an appropriate standard? Dirty or malfunctioning equipment affects the quality of cleaning outcomes and is a visible indicator of operational care.
Training compliance. Especially relevant in regulated environments, healthcare, food preparation, education, are vendor staff trained to the required standards, and is that training documented and current?
5 signs your cleaning vendor is underperforming
1. Complaints are increasing but inspection scores are static
When the number of complaints from building occupants is rising while your formal inspection scores stay flat, it usually means your inspections aren't capturing what occupants are experiencing. Either the inspection standards are too lenient, or the inspections are too infrequent. Either way, the gap between reported scores and user experience is a warning sign.
2. Response times for reactive requests are getting longer
A vendor that is progressively slower to respond to reactive cleaning requests is showing signs of operational strain, understaffing, poor scheduling, or competing priorities. This often precedes broader quality decline.
3. Restocking is consistently incomplete
Running out of soap, paper towels, or hygiene supplies mid-day is both a practical problem and a symptom. Vendors that are consistently missing restocking obligations are either not allocating enough time for the task or managing stock levels poorly. It's rarely a one-off.
4. Staff turnover is high and unannounced
If you're regularly encountering unfamiliar faces with no advance notice, it's worth asking questions. High staff turnover in cleaning teams affects quality, cleaning work has a skill and consistency component that new staff take time to develop. It may also indicate employment practices that create compliance exposure for you.
5. Issues are fixed only when raised, never self-reported
A vendor that consistently waits to be told about problems, rather than proactively identifying and reporting issues, is not managing quality. Proactive communication is a sign of a vendor that takes ownership. Its absence is a sign that your oversight is the only mechanism keeping performance from declining further.
What to do when you identify underperformance
The most important thing is to act before the problem becomes entrenched. The longer a pattern of underperformance is tolerated without a formal response, the harder it becomes to address.
Start with a documented performance conversation. Share the data, inspection scores, complaint records, response time logs, and ask for the vendor's explanation. There is often a solvable operational issue behind persistent underperformance: understaffing on a particular shift, a misunderstood contract requirement, a scheduling conflict.
If the conversation doesn't produce a change, escalate to a formal improvement plan with a specified timeframe and defined success criteria. Document everything.
If performance doesn't improve within the agreed timeframe, you have a well-documented case to support a contract review or replacement decision, and that documentation protects you if the decision is challenged.
