A clear, respectful complaint letter isn’t “being difficult”: it’s how you fix repeated cleanliness, odor, trash, or restroom issues fast while keeping things professional. When you document specifics and request a measurable solution, supervisors usually respond because sanitation and housekeeping directly affect health and safety.
Quick Answer Summary (What to Do)
Address the letter to the custodial supervisor/facilities manager/property manager (not the janitor) for faster action.
Lead with one sentence: what’s wrong + where + how long it’s been happening.
Add 3–6 bullet examples with dates, times, and exact locations.
Explain the impact (restroom sanitation, slip hazards, odors, pests, customer impressions).
Request specific corrective actions (schedule + checklist + restocking + spot-checks) and a reply deadline.
Keep a copy and follow up once in writing.

Should You Write to the Janitor or Their Supervisor?
My recommendation: write to the supervisor/manager in almost every situation.
Why this works better:
Supervisors control schedules, staffing, supply ordering, inspections, and performance management.
It reduces the chance your letter feels personal or confrontational.
It creates a proper record for contract compliance (if cleaning is outsourced).
If you’re in a rental building and the janitor reports to management, you can also borrow structure from a landlord-style complaint letter: Writing a Successful Complaint Letter to Your Landlord (Free Templates).
What to Document Before You Write (10 Minutes That Makes Your Letter “Unignorable”)
Capture:
Dates/times (at least 3 incidents)
Exact location (e.g., “2nd floor men’s restroom, sink #2”)
What you observed (objective facts, not judgments)
Photos (only if allowed; avoid capturing people)
Impact (odor complaints, supplies missing, slip hazards, pests, staff avoiding area)
This matters because sanitation in restrooms and washing areas is a recognized requirement in many workplaces.
The “Winning” Complaint Letter Structure
Use this exact flow:
Subject line: problem + location
One-sentence summary: repeated issue + timeframe
Evidence bullets: specific incidents (date/time/location)
Impact: health/safety/operations
Requested actions: measurable fixes + verification
Timeline: “Please confirm by ___”
Close: professional, cooperative
This mirrors the FTC’s advice: be clear, concise, and state what you want and how long you’ll wait for a response.
Complaint Letter Template (Copy & Paste)
[Your Name]
[Unit/Department/Office]
[Phone/Email]
[Date]
To: [Custodial Supervisor / Facilities Manager / Property Manager]
[Company/Building/School Name]
Subject: Repeated Cleaning/Sanitation Issue in [Location] — Request for Corrective Action
Dear [Name/Title],
I’m writing to document a repeated cleaning/sanitation issue in [specific location] that has occurred over [time period] and to request corrective action.
Examples observed (dates/locations):
[Date, Time] – [Exact location]: [Describe what you saw—facts only]
[Date, Time] – [Exact location]: [Describe what you saw]
[Date, Time] – [Exact location]: [Describe what you saw]
[Optional: Date, Time] – [Exact location]: [Describe what you saw]
Impact:
These conditions are affecting [restroom hygiene / occupant comfort / building appearance / safety]. Regular cleaning of high-touch surfaces helps reduce the spread of germs, and issues like wet floors or obstructed walkways can increase the risk of slips and falls.
Requested resolution (please confirm by [Day, Date]):
Confirm the cleaning schedule for [location] (frequency + task checklist).
Correct the immediate issues (e.g., trash removal, restocking soap/paper towels, floor cleaning, odor source) by [deadline].
Add a simple verification step for the next 2–4 weeks (log sheet, sign-off, or supervisor spot-check).
If supplies or staffing are constraints, please confirm what’s needed so this can be resolved permanently.
Please reply by [date] confirming the plan and completion timeline. I’m happy to provide additional details or documentation if helpful.
Sincerely,
[Your Name]
Attachments (optional): [Photos, incident log, prior emails/tickets]
Key Points That Make Your Letter More Effective
1) Be factual, not personal
Bad: “The janitor is lazy.”
Better: “Soap dispensers were empty on Feb 10, Feb 12, and Feb 14.”
2) Ask for measurable outcomes
Instead of “clean better,” request:
“Restock soap and paper towels daily”
“Empty trash by 6 PM weekdays”
“Mop and dry floors; place wet-floor signage during cleaning”
“Weekly supervisor inspection of restrooms”
OSHA specifically emphasizes maintaining restrooms in a sanitary condition and having proper handwashing supplies.
3) Don’t demand specific chemicals—request safe, labeled use
If you reference disinfecting, keep it simple: “Use appropriate products per label directions,” because safe disinfectant use depends on the product and surface.
4) Add a “why” that management can’t ignore: safety and risk
Housekeeping-related hazards (wet floors, cluttered walkways) are common contributors to slip/trip incidents, and employers are expected to keep walking-working surfaces clean and dry where feasible.
(If you want additional workplace documentation templates and tone guidance, see: Writing an Employee Warning Letter That Works — it’s useful for understanding what supervisors look for in “documented issues.”)
Real-Life Examples (How This Plays Out)
Example 1: Restroom supplies repeatedly missing
You list three dates the restroom had no soap/paper towels. You request a daily checklist and a two-week spot-check. Management resolves it quickly because it’s easy to verify and fix.
Example 2: Breakroom trash overflow and odor
You document weekend overflow twice and request a schedule adjustment or added pickup. The fix is usually staffing/schedule—not effort.
Example 3: Wet floors with no signage
You document two near-slip incidents and request signage and “clean one side of hallway at a time.” Safety framing gets immediate attention.
What If Nothing Changes?
Follow up once in writing (reply to the same email/attach the letter).
Escalate to the manager above facilities/property management/HR.
If it’s a contracted cleaning service, request a contract compliance review.
If you’ve reached the point where the environment is consistently unsafe or unhealthy and leadership won’t act, keep your options open with a clean exit plan:
As a reality check: private industry employers reported 2.5 million nonfatal workplace injuries and illnesses in 2024—so it’s reasonable to take avoidable hazards (like unsafe housekeeping conditions) seriously.
FAQ
Should I send the complaint letter to the janitor?
Usually, no. Send it to the custodial supervisor/facilities manager/property manager so the person who controls staffing, supplies, and inspections can fix it. If you need a parallel “management complaint” format, model the structure used in Writing a Successful Complaint Letter to Your Landlord.
Can I include photos?
Yes—if your workplace/building policy allows it. Keep photos focused on the issue (trash overflow, empty dispensers) and avoid capturing people.
Should I CC HR?
If it’s a workplace and the issue is ongoing, safety-related, or ignored after follow-up, CC’ing HR can help. If your complaint overlaps with broader workplace issues, you may also find wording ideas in 7 Sample Complaint Letters for Unprofessional Behavior.
What if the janitor is doing their best but doesn’t have supplies or time?
That’s exactly why writing to management works. Your letter can explicitly say: “If staffing or supplies are limiting factors, please confirm what’s needed to resolve this permanently.”
Can I request compensation for damages (ruined carpet, property damage, etc.)?
If you’re seeking reimbursement, keep that request separate and specific (what happened, cost, proof). This guide may help with phrasing: How to Request Compensation in a Complaint Letter (With Sample).
What if I’m at the point of quitting over this?
If leadership won’t address persistent sanitation or safety issues, protect your reputation with a neutral resignation letter and keep details for the appropriate complaint channels. Start here: Quitting a Toxic Work Environment: Templates That Work.
