Hiring your own custodian looks like the cheaper move, and on a small campus it usually is not. A business manager pricing one full-time hire against bids from commercial cleaning companies dallas tx schools already use is comparing two different products, because one buys a person’s hours and the other buys coverage. The argument is straightforward: a single-building private school under roughly 40,000 square feet gets more cleaned hours per dollar out of a contracted crew than out of one salaried custodian. The contract absorbs payroll taxes, benefits, floor equipment, consumables and backfill, all of which sit somewhere other than the wage on your budget worksheet. Run both columns for a full year and the gap stops being a matter of opinion.
One Custodian Buys Hours, Not Coverage
One custodian at 38,000 square feet is not understaffed on paper. Spread across about 300 students, that is a workable ratio for daily trash, restrooms and a vacuum pass through the classroom wing. The trouble is that a person is a schedule, not a service. He works eight hours, he takes two weeks off, and he catches the flu in February like everyone else. In practice what usually turns up on a campus this size is a slow slide: floors get burnished less often, the gym mats slip a week, the cafeteria deep clean waits for a Saturday nobody ever schedules. Nine weeks of summer is the only real window for strip and wax across the whole building, and one employee cannot finish that and still keep up with summer camps, the office wing and the deliveries that arrive all August. A single sick day and the plan goes sideways.
A business manager at a 300-student campus north of Dallas found this out the week before an accreditation visit. Her custodian had been out four days with a back injury, the substitute she scraped together could not run the floor machine, and the main corridor went into the walkthrough looking exactly as tired as it was. Nothing had gone wrong with the hire itself. The school had bought one person’s hours and then discovered it needed coverage.
Run the Full Year Cost Both Ways
Say the wage is $46,000, an illustrative figure for a suburban DFW campus and the one I will price here. Payroll taxes at 7.65 percent add $3,519. A modest benefits package, a health contribution and a small retirement match together, runs another $9,000. Consumables come off the same budget line, so add $4,800 for paper, liners and chemicals, plus roughly $2,200 a year for the burnisher and the autoscrubber once you spread the purchase and the repairs across their working life. Ten substitute days at $180 puts $1,800 on top. That comes to $67,319 against a $60,000 custodial budget line, before anyone has been paid to strip and wax a single hallway in July.
Now price the other column. A nightly contracted crew on 38,000 square feet, five nights a week, might quote somewhere near $4,000 a month for that scope, which is $48,000 a year with the summer project work either folded in or bid beside it. The crew arrives with its own machines, its own chemicals and its own night supervisor (the equipment repair bill quietly leaving your desk is the part nobody bothers to put in the proposal). Even if your real numbers land softer than the illustration, the direction of the answer rarely flips, because coverage is priced per square foot and per visit. What you are buying is a cleaned building rather than a filled position.
Buy Coverage That Survives a Sick Day
The line in a janitorial agreement worth arguing over is what happens when somebody does not show up. A real facility services contract names the crew size, the nights, the scope for each area and the substitute policy, so an absence becomes the contractor’s staffing problem instead of yours. Get the summer schedule in writing as well, since the strip and wax, the classroom resets and the carpet extraction all have to land inside the same nine weeks that every other school in the area is also bidding for.
Districts run this comparison in public, and they do not always land where you would guess. Christian County Now reported in July 2026 that the school board approved a $400,000 investment in an outside custodial service of 11 workers for its new consolidated high school, having determined that was slightly cheaper than hiring the additional staff itself. That is a far larger building than a 300-student campus, and a public district carries different constraints than a private one. The reasoning still scales down cleanly, because once benefits, absence coverage and equipment enter the comparison, contracted labor stops reading as the premium option.
Who handles the summer strip and wax?
In most facility services contracts that work belongs to the contractor, scheduled into the break as a project with its own crew and its own dates. Pin those dates down before you sign, because every campus within twenty miles wants the same nine weeks. A bid that leaves summer work out is not cheaper than the others, it is simply smaller.
What happens when a crew member does not show up?
The contractor backfills from its other accounts, which is the whole practical difference between a contract and a hire. Ask how many supervisors cover your zone at night and how fast a replacement actually reaches the building. A vendor who cannot answer that in one sentence is selling you hours again, just with a different invoice on top.
A custodian on staff is not a mistake, and a school with big grounds, a shop and a bus lot is often right to keep one. For a single 38,000 square foot building with one deep-clean window a year, though, the payroll route costs more and delivers less predictably. Build your own two columns first, then interview commercial cleaning companies Dallas TX schools already trust and make each of them quote scope, crew size and substitute policy line by line. The building either gets cleaned on the nights you agreed or it does not, and that is a far easier standard to hold a vendor to than a fair thing to ask of one tired employee.
