You searched for a monthly price and got a range so wide it told you nothing. One page says $200, the next says $3,000, and neither one says why.
Here’s the number, with the missing piece attached. The monthly office cleaning cost for most offices lands somewhere between about $200 and $2,800 for recurring service nationally. But the figure swings on how often the crew comes almost as much as on how big your office is. A monthly price with no cleaning frequency attached is meaningless, and that’s exactly the part the price charts leave off.
Get the frequency wrong in your head and you’ll compare a once a week quote to a five nights a week quote and think one company is gouging you. The same office can cost three times as much at five nights a week as it does at one. So the useful chart isn’t price by size. It’s price by size and how often you clean.
Monthly office cleaning cost by office size, with the frequency each range assumes
Here’s what recurring office cleaning typically runs per month, by size, with the cleaning frequency printed on every row. These are national industry ranges for standard office cleaning, not a quote for your building.
| Office size | Cleaning frequency | Typical monthly range (national) |
|---|---|---|
| Small, 500 to 2,000 sq ft | Once or twice a week | about $200 to $600 |
| Small, 500 to 2,000 sq ft | Five nights a week | about $600 to $1,200 |
| Mid, 3,000 to 7,000 sq ft | Two or three times a week | about $500 to $1,200 |
| Mid, 3,000 to 7,000 sq ft | Five nights a week | about $1,000 to $2,000 |
| Large, 10,000 to 20,000 sq ft | Three to five times a week | about $2,000 to $4,000 |
| Large, 20,000 sq ft and up | Daily | about $3,000 to $5,500 and up |
Read across a row and the frequency does as much work as the size. Read down the small office rows and you’ll see it plainly: the same little suite is a $300 job or a $1,000 job depending only on how many nights the crew shows up.
That’s why a bare “small office equals $X a month” number is a trap. It’s an average across frequencies nobody told you about.
Monthly cost’s only the starting number, and if you’re wondering how it fits with contract terms and choosing a company, see our complete guide to office cleaning services.
Frequency is the lever the charts hide
Cleaning is mostly labor, and labor is time. Five visits a week is roughly five times the hours of one visit a week, so it’s roughly five times the cost. Size sets how long each visit takes; frequency sets how many visits you pay for. Multiply them together and you have your bill.
This is why two honest quotes for the same square footage can look wildly different. One assumed twice a week, the other assumed nightly, and neither company was wrong. They were pricing different things.
It also means a smaller office cleaned every night can easily outcost a bigger office cleaned once a week. Before you compare a single dollar figure, settle how often your space actually needs attention. A quiet ten person office and a busy call center of the same size live in completely different rows of that table, and how often you should schedule office cleaning is the question to answer before you shop price at all.
How the three pricing models turn into a monthly number
Cleaning companies quote one of three ways, and each one becomes a monthly figure a little differently.
- Per square foot. The most common recurring model. A company multiplies your cleanable square footage by a per visit rate, usually about $0.07 to $0.20 a square foot for standard office work, then multiplies by how many visits you buy each month.
- Hourly. Common for smaller or variable jobs, generally around $30 to $75 an hour per cleaner depending on the market and the work. Your monthly cost is the hours it takes times the visits per month.
- Flat monthly contract. The company does the math above once and rolls it into a single predictable number. This is what most offices end up on, because it’s easy to budget and easy to compare across bids.
The per square foot rate is the engine under all three. If you want to understand where your number comes from, start with what office cleaning costs per square foot and the visit count stacked on top of it.
How to sanity check your own quote in two minutes
You don’t need a calculator tool to know whether a quote is in the right neighborhood. You need three numbers: your cleanable square footage, a per visit rate, and your visits per month.
Work it like this, with round hypothetical numbers:
- A 4,000 square foot office at $0.10 a square foot per visit is about $400 per visit.
- Cleaned three nights a week, that’s roughly 13 visits a month.
- $400 times 13 is about $5,200… which is clearly too high, so recheck the rate: at a more typical recurring rate the per visit figure lands lower, and three times weekly service for that size sits in the $500 to $1,200 range from the table above.
The point isn’t to nail the number to the dollar. It’s to catch a quote that sits far outside the range for your size and frequency. When one does, that’s your cue to ask what it includes, not to assume the company is cheating. A high number usually means more scope or more visits hiding in the fine print, and a suspiciously low one usually means less.
What a monthly chart can never tell you
A chart prices square footage. It can’t price your building. Four things move your real number that no table will show:
- Scope. Restrooms, a full kitchen, glass, and floor care all add labor. A quote for “general cleaning” and a quote that includes restroom restocking and periodic floor work are not the same job.
- Building type and layout. A chopped up floor plan with lots of private offices takes longer per square foot than one open room. Medical and food spaces cost more because the standard is higher.
- Access and timing. After hours work, security procedures, and tight service windows all shape the price.
- Your local labor market. Wages are the largest single cost in cleaning, more than supplies, equipment, and insurance combined. In the Scranton and Wilkes-Barre metro, building cleaning wages average about $18 an hour against roughly $20 nationally (Bureau of Labor Statistics, May 2025), so local pricing tracks the local market rather than a national chart.
None of that shows up in a size band. It’s why the honest version of this article ends with a walkthrough, not a chart.
So what should your office actually budget?
Work it in this order and you’ll land close before anyone quotes you.
- First, set your frequency. Light traffic professional office, once or twice a week is often plenty. Busy office with a kitchen and steady foot traffic, three to five nights. This choice moves your budget more than any other.
- Then find your size band in the table above and read the range on your frequency row, not the headline number.
- Then get one walkthrough quote to turn that range into a real figure for your building. A good local company will look at your space, ask how it’s used, and price the actual work rather than a national average.
If you want a number you can put in next year’s budget, that walkthrough is the step that gets you there. It costs nothing, and it’s the only way to move from a range to a price. In northeastern Pennsylvania, that’s a free estimate away.
Frequently asked questions
How much does office cleaning cost per month?
Most offices pay roughly $200 to $2,800 a month for recurring cleaning nationally, but the figure depends heavily on how often the crew comes. A small office cleaned once a week can be $200 to $600, while a large office cleaned daily can run $3,000 to $5,500 or more. Always read a monthly price alongside the cleaning frequency it assumes.
How much does it cost to clean a small office?
A small office of 500 to 2,000 square feet typically runs about $200 to $600 a month for once or twice weekly service, and roughly $600 to $1,200 a month if it’s cleaned five nights a week. The jump is almost entirely the number of visits, not the size.
How much is office cleaning per square foot?
Standard recurring office cleaning generally runs about $0.07 to $0.20 per square foot per visit nationally, with deeper or specialized work costing more. That per visit rate times your visits per month is what becomes your monthly bill.
Why are two quotes for the same size office so different?
Usually because they assume different cleaning frequencies or different scopes. One might price twice a week while the other prices nightly, or one includes restroom restocking and floor care the other leaves out. Compare the frequency and the task list, not just the dollar figure.
Is a flat monthly rate cheaper than paying per visit?
A flat monthly contract isn’t automatically cheaper, but it’s the most predictable and usually the easiest to budget and compare. The company does the per visit and frequency math once and gives you one number, which is why most offices settle on it for recurring service.
How often should an office be cleaned?
It depends on traffic and use. A quiet professional office is often fine with once or twice a week, while a busy office with a kitchen and heavy foot traffic usually needs three to five nights. Set this first, because it drives your monthly cost more than square footage does.
