Janitorial inspection checklist: how to run monthly checks

Clients rarely cancel a cleaning contract over one bad night. They cancel when small misses pile up and nobody notices but them. A short monthly inspection catches those misses first. Here's what to check, how to rate it, and a free printable checklist.

Why inspect every month

• You find problems before the client does. A missed corner fixed this week is a non-event. Six missed corners in a row lose an account.
• You have proof. A dated report with photos settles "you never clean the break room" in your favor.
• You coach your crew with specifics. "Restroom 2 mirrors were streaky" helps more than "do better".
• It's a reason to talk to the client about what's going well, and what else they might need.

A simple rating scale

Keep ratings simple so they're consistent from month to month:

What to check, area by area

• Entry glass and door handles clean, no smudges

Halls, stairs and common areas

How to run the inspection

1. Pick a regular time, the same week each month, ideally the morning after a clean.
2. Walk the same route every time, using the same checklist, so results compare month to month.
3. Rate every item, and photograph anything rated Repair or Urgent.
4. Give every problem an owner and a date: who fixes it, and by when.
5. Close the loop. Check that it was fixed, and record it.
6. Share a short summary with the client: what was checked, what was found, and what you've already fixed.

Use the same areas as your crew's cleaning checklist, so every finding points to a line on their list. See our office cleaning checklist for daily, weekly and monthly tasks by area.

Now and then, invite the client's contact to walk with you. It shows confidence, and you'll hear about small annoyances before they become reasons to switch.
