The difference between a contractor who self-reports quality and one whose quality process holds up under an independent look — for facilities managers in Washington County, MN.
Every janitorial contractor will tell you they have a quality control process. Fewer can describe what it actually looks like on a Tuesday night in a building they have been cleaning for three months. This article describes what a meaningful quality inspection involves, so you can evaluate whether what your current or prospective contractor does qualifies.
A quality inspection is not a supervisor following the cleaning crew while they work. That is supervision — a different and useful thing, but not a quality control process in any meaningful sense. An inspection that happens simultaneously with the work being inspected cannot catch what gets done when no one is watching, which is the actual quality control question.
A quality inspection is also not a post-clean walkthrough that consists of a supervisor looking at the lobby, confirming the floors are swept, and signing off. That is a check on the most visible 5% of the scope and tells you nothing about the restroom cleaning, the break room surfaces, or the trash removal in private offices.
A substantive janitorial quality inspection in a commercial facility checks the scope against the written agreement, area by area. In practice, it looks like this:
Every fixture wiped and disinfected — not just the visible surfaces. The base of the toilet, the flush handle, the door handle inside and out, the soap dispenser head, and the underside of the sink edge where residue accumulates. Supply levels confirmed and logged. Floor condition around the base of fixtures checked, because this is where routine mopping misses and buildup develops over weeks.
Under furniture where mopping typically shortcuts. Behind doors. In the corners of corridors. These are the areas where dust accumulates when the mop takes the path of least resistance. A streak test on a cleaned hard floor — running a finger along a baseboard — tells you whether the dust mop stage actually happened or whether the floor was damp-mopped over dry dust.
Every waste receptacle emptied and liner replaced. In Washington County office environments — particularly in buildings with private offices that are not always occupied — it is common for waste in less-trafficked rooms to be skipped rather than checked. An inspection confirms every room, not just the ones the crew visits first each night.
Light switches, door handles, conference room table surfaces, copy machine buttons. These are the surfaces with the highest contamination rate per square inch in any commercial building and the ones most often skipped in a rush. In a disinfection context — particularly in medical or dental offices — this is the check that carries the most consequence.
A real quality inspection produces a written record of what was found and what action was taken. Not a general "looks good" sign-off — a specific log that notes any missed tasks, any product issues, any areas that need follow-up on the next visit. This log becomes the documentation trail that lets you verify, over months of service, whether quality is improving, stable, or declining.
The most useful quality check for a new janitorial program is the 30-day review — a scheduled conversation between the facilities manager and the contractor at the end of the first month. At this point, the novelty of a new contractor has worn off, the crew has settled into their routine, and any shortcuts that were going to appear have appeared. The 30-day check-in surfaces those issues before they become entrenched habits.
What makes a 30-day check-in substantive versus ceremonial: a specific agenda that goes through the scope line by line, a record of any items that did not meet the written commitment, and a documented action plan for addressing them. A 30-day call that ends with "everything looks fine" without having reviewed the scope is not a quality review — it is a relationship maintenance call.
