If you’ve tried to budget for commercial cleaning, you’ve probably noticed something frustrating: almost nobody publishes prices. Every website says “request a quote,” and every quote seems to be built on a different math. This guide explains how commercial cleaning is actually priced, what typical ranges look like, and how to tell a fair proposal from a lowball bid you’ll regret by month three.
Most recurring commercial cleaning in the U.S. lands between $0.08 and $0.25 per square foot per visit, or roughly $30–$50 per labor hour, and Greater Portland tracks close to those national ranges. The number that matters most isn’t the rate, though. It’s what’s in the scope: two identical rates can buy very different amounts of cleaning.
The three ways commercial cleaning is priced
Nearly every quote you’ll receive uses one of three models. None is “correct.” They fit different situations, and a good vendor will tell you which one fits yours.
| Model | Typical range | Best fit | Watch out for |
|---|---|---|---|
| Per square foot | $0.08–$0.25 / sq ft / visit for routine janitorial | Larger spaces (5,000+ sq ft) with predictable layouts | Rates quoted without a walkthrough, where the number is a guess |
| Per visit (flat) | Roughly $150–$800+ per visit depending on size and scope | Small offices and storefronts under ~5,000 sq ft | A vague scope, where “standard cleaning” means whatever the crew decides that night |
| Monthly contract | Visit price × frequency, often with a modest volume discount | Recurring service at 2–7 visits per week | Contracts with no inspection or reporting terms, so you’re buying a promise with no meter on it |
Hourly pricing exists too, typically $30–$50 per cleaner per hour in northern New England, but for recurring work it usually gets converted into one of the models above, because you’re buying an outcome, not hours.
Typical cost ranges by facility type
Facility type moves the rate because it changes the work: a medical office has disinfection protocols a showroom doesn’t; a restaurant floor takes real degreasing. These are typical U.S. ballparks for recurring service, so treat them as a sanity check for quotes, not a menu.
| Facility type | Typical per sq ft / visit | What pushes it higher |
|---|---|---|
| General office | $0.08–$0.15 | Dense workstations, kitchens, daytime cleaning |
| Medical & dental | $0.12–$0.25 | Exam-room protocols, disinfection standards, documentation |
| Restaurant & food service | $0.12–$0.25 | Degreasing, floor drains, health-code detail work |
| Retail & storefront | $0.05–$0.12 | Glass frontage, entry mats, high traffic |
| Gym & fitness | $0.10–$0.20 | Equipment wipe-downs, locker rooms, sweat-zone disinfection |
One-time and project work is priced differently: floor care like a VCT strip & wax typically runs $0.30–$0.60 per square foot as a project, and carpet extraction around $0.15–$0.30 per square foot. If a recurring quote looks surprisingly low, check whether floor care was quietly left out, since it’s the most common gap.
What actually moves your number
When we build a quote for a Greater Portland facility, five inputs do most of the work:
- Frequency. The biggest lever by far. Five nights a week costs more per month than one, but less per visit, because the space never gets far from clean. Cutting frequency to save money often backfires: each visit gets heavier and slower.
- Facility type and finish. Exam rooms, commercial kitchens and locker rooms carry protocols and detail work that a simple office doesn’t.
- Floor care. Hard-floor maintenance and periodic restoration are either built into the plan or billed as projects. Either is fine, but it should be written down which one you’re getting.
- Day vs. overnight. Cleaning around an active workplace is slower and more constrained than after-hours work. Overnight is usually the better value if your building allows it.
- Consumables. Paper products, liners and soap can be included or passed through. A quote that’s $200/month cheaper but excludes consumables isn’t cheaper.
Want a real number instead of a ballpark?
We’ll walk your facility and hand you a transparent, itemized proposal: every task, every frequency, one price. No obligation.
What a fair quote includes (and a lowball leaves out)
Here’s the uncomfortable truth about the cheapest bid: cleaning is labor. When a quote comes in 30% under everyone else’s, the vendor hasn’t discovered efficiency. They’ve budgeted fewer hours than the job takes. You’ll get the missing hours back as skipped details, and you’ll find out gradually.
A quote worth signing should include:
- An itemized scope of work with every task listed, mapped to a frequency (daily, weekly, monthly, quarterly). If “dust ledges” isn’t written down, it isn’t happening in month three.
- A walkthrough behind the number. Any rate quoted sight-unseen is a placeholder that changes later.
- Inspection and reporting terms. How is quality measured, how often, and do you see the results? This is the difference between buying a service and buying a hope.
- Proof of insurance and vetted staff: bonded, insured, background-checked, in writing.
- Clarity on consumables, supplies and equipment: who provides what.
That’s the standard we hold our own proposals to. SmartSweep is rarely the cheapest bid in a Greater Portland stack. We’re priced for the hours the job actually takes, plus the inspections and reporting that keep visit fifty as good as visit one. The value shows up in what you stop paying for: re-dos, complaints, vendor churn, and your own time spent chasing a crew.
A note on Greater Portland pricing
Southern Maine’s labor market keeps cleaning rates close to national averages, so expect the middle of the ranges above rather than the bottom. We serve facilities within about 35 miles of Portland, from single-suite dental offices to multi-tenant buildings, and every account gets the same structure: a walkthrough, an itemized scope, and a documented inspection cadence.
