Janitorial QA inspection scoring rates a sample of rooms against the written scope, rolls those ratings into area and building scores, and tracks every deficiency until it is corrected. A sound system uses a consistent rubric, a representative sample of each area type, weighting for areas occupants care about most, a defined target score and clear response times for deficiencies. The point is not the number itself but the trend and the corrective actions it drives.
Why score at all?
Without inspections, cleaning quality is measured by complaints, which arrive late and only for the most visible problems. Scoring gives you:
- Early warning before occupants notice
- Objectivity in conversations with the vendor
- Trends that show whether service is improving or slipping
- Comparison across buildings or periods
- Accountability tied to the contract
Large buyers, including federal agencies managed through the GSA's facilities programs, use structured inspection for custodial contracts. The approach works at any scale.
Step 1: Choose a rubric
Two common approaches:
Pass/fail by task: each scope item is marked done or not done. Simple and objective, good for smaller buildings.
Graded scale by area: each area is rated on a scale tied to the scope or to recognized standards such as the APPA cleanliness levels. Better for nuance.
A practical graded rubric:
| Rating | Meaning | Points |
|---|---|---|
| Meets scope | All tasks complete to standard | 4 |
| Minor deficiency | Small miss not visible to occupants | 3 |
| Major deficiency | Miss occupants would notice | 1 |
| Critical | Health, safety or security issue | 0 |
Step 2: Sample rooms
Inspecting every room every time is rarely practical. Instead, sample:
- Every restroom, because they matter most
- All high-visibility areas: lobby, reception, main conference room
- A rotating sample of offices, classrooms or exam rooms, for example 10 to 20 percent each inspection
- Problem areas from previous inspections
Rotate the sample so every room is inspected over a cycle.
Step 3: Weight what matters
Not all areas are equal. Weighting keeps the building score honest:
| Area | Example weight |
|---|---|
| Restrooms | 30% |
| Entries and lobbies | 20% |
| Breakrooms | 15% |
| Offices and workspaces | 25% |
| Corridors and other | 10% |
A building with spotless offices but neglected restrooms should not score well.
Step 4: Calculate the score
- Average the ratings within each area.
- Convert to a percentage of the maximum points.
- Multiply each area's percentage by its weight.
- Add the weighted results for a building score.
Many organizations set a target such as 90%, with a lower threshold that triggers a corrective plan.
Step 5: Close out deficiencies
The score is less important than what happens next. Every deficiency should be logged with:
- Location and description, ideally with a photo
- Severity
- Responsible person
- Correction deadline: critical immediately, major within a short defined window, minor by next visit
- Verification that it was fixed
Step 6: Look for patterns
Repeated deficiencies point to causes:
| Pattern | Likely cause | Fix |
|---|---|---|
| Same task missed in many rooms | Training or checklist gap | Retrain or revise checklist |
| One area always low | Not enough time allotted | Adjust scope or labor |
| Scores drop on certain nights | Staffing or schedule issue | Change schedule or assignment |
| Seasonal drop | Winter soil, events | Seasonal scope adjustment |
Step 7: Share and review
Review scores and trends with the vendor monthly or quarterly. Good vendors welcome it. See janitorial account management.
Calibrating with your vendor
At the start, inspect together. Agree on what "meets scope" looks like in your building. Calibration prevents disputes later and makes the vendor's own inspections more credible.
How Northmark scores
Our quality assurance program uses a graded rubric tied to your scope, scheduled supervisor walkthroughs, weighted area scores and deficiency close-out. For portfolios, scores are reported by site. See multi-site janitorial.
Frequently asked questions
What is a good janitorial inspection score?
Many organizations target around 90% on a weighted rubric, but the right target depends on the rubric and building.
How often should janitorial inspections happen?
Weekly or biweekly for busy or sensitive buildings, monthly for smaller or lower-risk ones.
Should restrooms be weighted more heavily?
Usually yes. Occupants judge cleanliness largely by restrooms.
What should happen when an inspection finds a problem?
Log it, assign it, correct it within a defined time, verify the fix and look for patterns.
