Janitorial Bid Comparison: What the Numbers Hide

Three janitorial bids land on your desk for the same building, and the monthly prices are thousands of dollars apart. Every janitorial bid claims to cover “nightly cleaning of all areas,” so the cheapest one looks like the obvious choice. However, the price gap almost always comes from assumptions buried in the math, and those assumptions decide what your building looks like at 7 a.m.

Facility managers in Dallas and Fort Worth compare bids like this every time a contract comes up for renewal. This guide covers what a complete bid should show, why numbers vary so much, and how to line them up fairly before you sign.

Quick answer: compare janitorial bids by labor hours and scope first, then price. Ask every vendor for the nightly hours behind their number, the task list by area, and what’s excluded. A bid that can’t show its hours can’t show you what you’re buying.

What Should a Janitorial Bid Include?

A complete janitorial bid explains how the price was built, and the total is only the last line. If any of these pieces are missing, you’re comparing a guess to a plan.

• Scope by area: tasks listed separately for offices, restrooms, break rooms, lobbies, and any specialty spaces.
• Frequency for each task: nightly, weekly, monthly, or quarterly, written per task.
• Estimated labor hours: total cleaning hours per night or per week.
• Crew size and supervision: how many cleaners, and who checks their work.
• Consumables: whether paper towels, toilet tissue, can liners, and hand soap are included or billed separately.
• Periodic work: floor care, carpet extraction, and high dusting, with their own schedule and price.
• Insurance and staffing: general liability, workers’ compensation, and whether cleaners are employees or subcontractors.
• Exclusions: anything the vendor won’t do, written down.

For example, a bid for a 40,000-square-foot office in Las Colinas should tell you roughly how many hours a night the crew will spend on site. If it only lists a monthly total, ask for the hours before you compare anything else.

Why Do Janitorial Bids for the Same Building Vary So Much?

Janitorial bids vary mostly because vendors assume different labor hours for the same space. Labor is the largest cost in commercial cleaning, so a vendor that plans fewer hours can quote a much lower price.

The industry uses production rates to estimate those hours. A production rate is how many square feet one cleaner can service in an hour. For routine office cleaning, many bids fall somewhere between 2,500 and 4,000 square feet per hour, depending on how dense the space is and what the scope includes.

That range explains a lot. Take the same 40,000-square-foot office cleaned five nights a week:

• At 2,500 square feet per hour, the job needs about 16 labor hours a night.
• At 4,000 square feet per hour, it needs about 10 hours.
• A bid that implies 6,000 or more square feet per hour is planning roughly 6 or 7 hours a night.

That third bid is usually the cheapest one on the table. In practice, it can only hit that pace by skipping tasks. Vacuuming turns into “spot vacuuming,” restrooms get a quick wipe instead of a full reset, and dusting slides to “as needed.”

Other factors move the number too. Consumables may be included in one bid and billed separately in another. Meanwhile, one vendor may price supervision and quality inspections into the contract, while another leaves them out.

How Do You Compare Janitorial Bids Side by Side?

The fairest way to compare bids is to convert each one into the same units. That way, you’re judging the plan behind the price, and the monthly total stops doing all the talking.

1. Confirm the scope matches. Put the task lists next to each other. If one vendor included monthly high dusting and another didn’t, the bids aren’t equal yet.
2. Find the labor hours. Ask each vendor for nightly or weekly hours if the bid doesn’t show them.
3. Calculate the implied production rate. Divide your cleanable square footage by the nightly hours. Anything far outside the typical range deserves a question.
4. Calculate the effective hourly rate. Divide the monthly price by the monthly labor hours. A very low number often means thin wages, no supervision, or uninsured labor.
5. Separate periodic work. Pull floor care and carpet cleaning out of each bid and compare them on their own.
6. Check consumables. Add the cost of supplies to any bid that excludes them.

After those six steps, the spread between bids usually shrinks. Sometimes the cheapest bid is still the best value. More often, the low bid turns out to be a smaller scope at a similar price.

What Red Flags Show Up in a Low Janitorial Bid?

The biggest red flag in a low janitorial bid is missing information. A vendor who is confident in their pricing has no reason to hide the hours or the task list.

• No labor hours listed, even after you ask.
• Vague scope language like “general cleaning” or “clean as needed.”
• No supervision plan or quality inspection schedule.
• Subcontracted or 1099 crews with no clear accountability.
• No workers’ compensation coverage.
• A price well below the other bids with no clear explanation.

The workers’ comp point matters more in Texas than almost anywhere else. Texas is the one state where most private employers can opt out of workers’ compensation coverage. As a result, a vendor without it can underbid competitors, and an injury on your property can become your problem. Our breakdown of commercial cleaning insurance requirements in Texas explains what to ask for.

When Is the Higher Janitorial Bid the Better Value?

The higher bid is often the better value when it buys hours, supervision, and consistency. Those three things are what keep a building clean past the first 90 days of a contract.

For instance, a bid that plans enough hours to finish the scope every night means fewer complaints from tenants and employees. In addition, a dedicated account manager who inspects the work catches problems before you do. That saves you time you’d otherwise spend walking the building and sending emails about missed trash.

Still, higher isn’t automatically better. A high bid should be able to explain its hours the same way a low bid should. If a vendor can’t tie their price to the work, the number doesn’t mean much in either direction.

Once a vendor is in place, the same numbers become your baseline for commercial cleaning quality control. If inspection scores start dropping, the first thing to check is whether the crew is still working the hours the bid promised.

How Allied Facility Care Builds a Bid

Our bids start with a walkthrough led by the same team that will manage your account. We note floor types, count restrooms and fixtures, and ask how your building is used across the week. Then we turn that visit into a written proposal with a task list for each area.

We’re glad to walk through the hours behind our price, because that’s how you know the scope is realistic. Since 1996, we’ve cleaned offices, medical facilities, warehouses, and multi-tenant buildings across Dallas, Fort Worth, Arlington, Plano, and Irving. You can review our full range of commercial cleaning services to see what we cover.
