Custodian Resume Guide: Square Footage, Floor Care, Building Trust
The short answer: Custodial work is assigned by area, so write the area: square footage, classrooms or offices, restrooms, buildings. Then the floor care equipment you can run and the strip-and-refinish cycle you've completed, because floors are the skilled part of the job. Then the trust facts — keys, alarm codes, opening and locking up, event setup — plus your attendance, since one call-out leaves a building uncleaned.
A custodial supervisor is assigning buildings, not tasks. They want to know how much area you've carried, whether you can run the machines without wrecking a floor, and whether the building can be left in your hands overnight.
Area first — it's how the job is measured
✗ "Responsible for cleaning assigned areas, emptying trash, and performing general custodial and maintenance duties as needed."
✓ "Sole second-shift custodian, 68,000 sq ft elementary building — 32 classrooms, 6 restrooms, gym and cafeteria; nightly autoscrubber run on all hard floors, restroom sanitation, trash and recycling for the building, and lock-up."
Square footage, room counts, restroom counts, floors, and number of buildings: those four facts place you immediately. Say whether you worked alone or on a crew and which shift — sole overnight responsibility for a building is a specific competence and should be labeled as one. Then name the setting, because they're different jobs: school district, college campus, commercial office, hospital or clinic, municipal building, church, warehouse, or contracted janitorial covering multiple sites.
Floor care is the skilled half
Anyone can empty a bin; floors are where experience shows. Name the machines you operate — autoscrubber (walk-behind or rider), buffer and high-speed burnisher, carpet extractor, wet-dry and backpack vacuums, propane equipment where used — and the processes: scrub and recoat, full strip and refinish with coat counts, carpet extraction and spot treatment, tile and grout, concrete sealing, and gym floor care including screening and finishing, which districts take seriously. If you've run a summer floor program across a building, that's a headline, not a footnote.
Then chemical and safety training by name: hazard communication and safety data sheets, correct dilution and dispensing systems, bloodborne pathogen training for cleanup, personal protective equipment, lockout/tagout where relevant, and ladder and lift safety. These are the same chemical-and-equipment specifics that matter in any cleaning trade — but here the unit is the building rather than the room.
School work has its own calendar
Term time is cleaning around people: classrooms on a nightly rotation, restrooms multiple times a day, cafeteria turnover, spill and illness response, and keeping out of the way of teachers and students. Summer is the deep cycle — furniture out, floors stripped and refinished, rooms reset to the custodial standard before staff return — and having worked a full summer cycle tells a district you understand the year's real shape.
Then the parts nobody writes down: event setup and teardown (gym and cafeteria configurations, bleachers, assemblies, graduation, evening rentals), snow and ice removal and light grounds work in many districts, minor repairs, and boiler or mechanical checks where the role includes them. If your job crossed into trades work, note what you handled and read the maintenance technician guide for how to write the multi-trade side. Districts also require background clearance to work around children — say that you hold it or can pass it.
Trust and reliability
A custodian often holds keys to an entire building and is alone in it after hours. Supervisors think about that constantly and candidates almost never address it: keys and master access held, alarm codes and arming procedure, opening or locking up, after-hours contractor and vendor access, and found-property handling. One or two lines cover it, the same way any trusted-alone role should.
Then attendance, stated plainly, because one absence means a building goes uncleaned: your record, years at each site, shifts covered for colleagues, and your availability for evenings, weekends and summer. "Four years on second shift with no attendance issues" is worth more than any adjective, which is the show-the-behavior rule at its most practical.
Starting out, and moving up
No custodial history? Count real work: housekeeping, warehouse, kitchen, groundskeeping, or any job with equipment and a standard. Add safety training, availability, and a driver's license if the role covers multiple sites — the first-resume approach in a field that hires on reliability. Moving toward lead custodian, head custodian, or facilities supervisor? Write the ownership bullets: you trained new custodians, ordered and managed supplies, planned the summer schedule, inspected others' work, coordinated with contractors, or held the head-custodian keys when the lead was out. Those are the trust markers.
