Two janitorial bids for the same building can arrive hundreds of dollars apart and describe what looks like the same service. That's the trap. The lower number almost always wins the room, and six months later the property manager is fielding tenant complaints about restrooms, arguing about supplies, and paying change orders that erase every dollar the switch was supposed to save.

A janitorial bid isn't a price. It's a set of assumptions about labor hours, chemicals, equipment, insurance, and what happens when something breaks. Read it that way and the cheap bid usually stops looking cheap.

Why Do Two Bids for the Same Building Look So Different?

Cleaning pricing has three real ingredients: labor, materials, and equipment. A useful breakdown of janitorial pricing treats those three as the whole story, and labor is almost always the biggest slice. When one bid comes in dramatically lower than another, the vendor has cut one of those three, or narrowed the scope so it looks like they're pricing the same job when they aren't.

Ask for the assumed hours per night and the head count on site. If the low bid puts one cleaner on a footprint that everyone else is staffing with two, you've found the difference. You're not buying a better price. You're buying a slower clean.

What Should Actually Be Priced Line by Line?

A proposal that gives you one monthly figure and a scope paragraph is hiding the math. Push for a line-item view so you can compare bids apples to apples. The items below are the ones most often blurred together or left out entirely.

• Labor hours and wage load. The bid should show cleaner hours per shift, supervisor time, and the fully burdened wage rate, not a lump sum. Payroll taxes, workers' comp, and any benefits belong here, and a bid that assumes minimum wage in a tight labor market will not hold its crew.
• Consumables. Toilet paper, hand soap, trash liners, and paper towels can be included, billed at cost-plus, or excluded entirely. All three are legitimate. Only one matches what you assumed you were buying.
• Chemicals and equipment. Floor pads, vacuum bags, autoscrubber wear parts, and cleaning solution get consumed every month. If the bid doesn't say who pays, you will.
• Periodic services. Carpet extraction, hard-floor strip and wax, high dusting, window interiors, and pressure washing are usually quoted separately. Confirm frequency, price per event, and whether they're built into the monthly figure or billed on top.
• Day porter coverage. A daytime attendant for restrooms, lobbies, and spills is a different product than a night crew and priced differently. Buildings that need one and don't buy one end up paying for it in tenant complaints.
• Insurance and bonding. General liability, workers' comp, and a janitorial surety bond covering theft and damage on your premises are baseline. Ask for certificates before you sign, not after an incident.
• Management and QC. Site inspections, a ticketing system for complaints, and a named account manager cost money. A bid without them is cheaper because you're doing that work.

Where Does the Cheap Bid Cut Corners?

The most common cut is labor hours. A vendor prices the job at 25 hours a week when the building needs 40, wins the contract, and the crew moves through fast enough that surfaces get wiped but nothing gets cleaned. Restrooms are usually where you notice first.

The second most common cut is compliance overhead. Chemical training, labeled bottles, current safety data sheets, and PPE are required under the OSHA standards that apply to cleaning contractors. A vendor who skips that training runs cheaper right up until an inspector or an injury shows up in your building.

The third is supplies. If consumables aren't spelled out, expect a mid-contract conversation about who's stocking the restrooms. That conversation usually ends with a change order.

How Do You Compare Bids on Total Cost, Not Sticker Price?

Normalize the bids before you compare them. Put every proposal on the same denominator: cost per square foot per month for the recurring scope, with periodics broken out separately at a per-event price and an annual frequency. That single move usually reshuffles the ranking.

Rates vary widely by market, building type, and frequency, and public pricing benchmarks can help you sanity-check where a bid sits. When a proposal comes in well below the range for your building class, stop asking whether corners were cut and start asking which ones.

Then read the contract terms. Annual escalators tied to a wage or CPI index, termination for convenience with a reasonable notice period, and a clear scope-change process are worth more than a few cents per square foot. A bid that's a penny cheaper and locks you into a year with no out is the expensive one.
