Office Cleaning Rates Without the Mess

Pricing Model	Typical Range
Per square foot (per visit)	$0.12 – $0.25
Hourly rate (per cleaner)	$35 – $75
Monthly contract (small office)	$200 – $500
Monthly contract (medium office)	$500 – $1,200
Monthly contract (large office)	$1,200 – $3,500+

These numbers shift based on your office size, location, cleaning frequency, and the specific services you need. Denver Metro Area businesses may see rates toward the higher end of national ranges, especially for Class A office buildings and facilities with specialized cleaning requirements.

Budgeting for cleaning shouldn't be a guessing game. Whether you manage a 1,000 sq ft startup suite or a 20,000 sq ft corporate campus, understanding what drives these costs puts you in control.

I'm Carlos Castillo II, owner of The Crew Janitorial — a Denver-based commercial cleaning company my grandfather founded in 1982 — and I've spent years helping local businesses navigate average office cleaning rates across a wide range of facility types and budgets. In this guide, I'll break down exactly what you should expect to pay, and why.

Understanding Average Office Cleaning Rates in 2026

As we move through 2026, the commercial cleaning landscape has evolved. While the core mission remains the same—keeping your workspace healthy and presentable—the costs associated with professional labor, high-grade disinfectants, and specialized equipment have seen a steady rise of 8% to 12% over the last two years.

When we look at Commercial Cleaning Rates 2026: Prices, Chart & Cost Calculator, it’s clear that transparency is the new industry standard. Businesses are no longer satisfied with "guesstimates." They want to see exactly where their dollars are going. In cities across the Denver Metro Area—from the tech hubs in Centennial to the bustling streets of Westminster—rates are influenced by a competitive labor market and a high demand for reliability.

Average Office Cleaning Rates per Square Foot

For many of our clients in Denver and Aurora, square footage pricing is the preferred method because it offers the most predictability. Generally, average office cleaning rates range from $0.12 to $0.25 per square foot.

However, "cleanable square footage" is rarely the same as your total lease footprint. We don't charge you for the space occupied by floor-to-ceiling server racks or massive storage crates that never move. The density of your office also plays a massive role. An open-concept office with 50 desks in a 5,000 sq ft space requires much more detail work—and therefore a higher rate—than a 5,000 sq ft warehouse office with only three desks and a lot of empty floor. High-traffic areas like lobbies, elevators, and breakrooms naturally demand more attention and can push your per-square-foot rate toward the higher end of the spectrum.

Average Office Cleaning Rates per Hour

Sometimes, a flat square footage rate doesn't make sense—especially for smaller offices or those with irregular needs. In these cases, we look at hourly benchmarks. Nationally, How Much Does Commercial Cleaning Cost? [2026 Data] | Angi notes that rates typically fall between $35 and $75 per hour per worker.

In our local market, including Lakewood and Broomfield, the hourly rate often reflects the level of expertise and the timing of the service. Daytime cleaning, which is becoming more popular for businesses that want a visible "clean presence," can sometimes cost more due to the need for staff who can work around your employees without being a distraction. Nighttime service remains the standard for deep, focused work, allowing our teams to move quickly through the space to maximize productivity.

Office Size (Sq Ft)	Avg. Monthly Cost (3x/week)	Avg. Hours per Visit
0 – 1,000	$200 – $400	1
1,000 – 5,000	$400 – $1,200	1 – 5
5,000 – 10,000	$1,200 – $2,200	5 – 10
10,000 – 20,000	$2,200 – $3,500	10 – 20
20,000 – 40,000	$3,500+	20 – 40

Small Offices Under 5,000 Square Feet

For micro-offices in places like Golden or Wheat Ridge, the average office cleaning rates often hover between $0.15 and $0.20 per square foot. Why the higher rate? It comes down to "minimum call-out fees." Even if an office only takes 45 minutes to clean, a professional company still has to account for travel time, fuel, and equipment setup. Most small offices find their sweet spot with twice-weekly or thrice-weekly cleaning to keep costs manageable while maintaining a professional appearance.

Large Facilities Over 10,000 Square Feet

When we step into large corporate campuses in Denver or Longmont, economies of scale kick in. Rates often drop to $0.12–$0.16 per square foot. At this size, we often deploy dedicated onsite teams or "day porters" who stay at your facility throughout the shift. This volume allows for more aggressive pricing because our teams spend less time traveling and more time actually cleaning. It’s efficient for us, and cost-effective for you.

Location is a primary driver. Within the Denver Metro Area, labor costs can vary by city. Providing the best office cleaning services for Denver businesses means we have to account for the specific logistics of each area, from the parking challenges of downtown Denver to the sprawling layouts in Highlands Ranch.

Frequency and Scheduling

How often do you want us there? A daily cleaning schedule (5 days a week) will always have a higher monthly total than a twice-weekly schedule, but the cost per visit is often lower on a daily contract. We also have to consider "off-peak" hours. Most of our work happens between 6:00 PM and 2:00 AM. If you require weekend-only cleaning or emergency Sunday shifts, you can expect to see a weekend premium of 10% to 20%.

Facility Type and Specialized Requirements

The type of business you run dictates the "level of clean" required.

Medical Offices: These require EPA-approved disinfectants and strict adherence to OSHA and CDC guidelines. Because of the risk of cross-contamination and the need for specialized training, medical rates are typically 15% to 30% higher than general office rates.
Retail Spaces: High foot traffic means more mud tracked in during Colorado winters and more fingerprints on glass. This usually results in a higher frequency of floor care.
Industrial/Warehouses: In places like Henderson or Brighton, warehouse offices often deal with heavy dust and grime from the floor. Cleaning these spaces requires more "elbow grease" and specialized degreasers.

Specialized Service Costs: Beyond Basic Janitorial Work

Your standard contract usually covers the basics: trash removal, vacuuming, restroom sanitation, and surface dusting. But every once in a while, your office needs a little "extra love."

Carpet Cleaning: Most offices should have their carpets professionally extracted every 6 to 12 months. Expect to pay between $0.25 and $0.50 per square foot for this service.
Window Washing: For interior windows and ground-floor exteriors, rates usually range from $0.50 to $1.00 per square foot, or $4 to $8 per pane.
Floor Stripping and Waxing: To keep those VCT tile floors shining in your breakroom or lobby, stripping and waxing typically costs $0.30 to $0.50 per square foot.
Deep Cleaning: This is a top-to-bottom scrub that includes things like cleaning inside light fixtures, detailed baseboard scrubbing, and disinfecting every "touch point" in the building. This is often priced at $0.15 to $0.25 per square foot.

One-Time Deep Cleans vs. Recurring Contracts

If you’re moving into a new space in Arvada or Littleton, a one-time "move-in" clean is essential. However, these one-time jobs are always more expensive than recurring service. When you sign a recurring contract, you can typically save 10% to 20% compared to "on-call" cleaning. Why? Because regular maintenance prevents the heavy dirt buildup that makes one-time cleans so labor-intensive. To learn more about how to set up these agreements, read everything you need to know about hiring a cleaning company.

How do I calculate my monthly office cleaning budget?
The easiest way to estimate your budget is to use this simple formula: Monthly Cost = (Cleanable Sq Ft × Rate per Sq Ft) × Visits per Month

For example, if you have a 3,000 sq ft office in Centennial and you want it cleaned 3 times per week (12 times per month) at a rate of $0.15 per sq ft: (3,000 × $0.15) × 12 = $5,400 per month.

That for very small spaces, companies will often just give you a flat monthly fee (e.g., "$450/month for twice-weekly service") rather than breaking it down by the foot.
Are commercial cleaning services tax deductible?
Yes! In almost all cases, commercial cleaning is considered a "necessary and ordinary" business operating expense. This means you can typically deduct the full cost of our services from your business's taxable income. Of course, we always recommend double-checking with your CPA, but rest assured that keeping your office clean is a smart tax move as well as a healthy one.
Why do medical office cleaning rates cost more?
Medical cleaning isn't just about making things look shiny; it’s about infection control. Our teams in medical facilities use hospital-grade, EPA-registered disinfectants that have specific "dwell times" (the amount of time a chemical must sit on a surface to kill pathogens). The training required to handle biohazards and prevent cross-contamination is extensive. When you pay a premium for medical cleaning, you aren't just paying for soap—you're paying for the peace of mind that your facility meets stringent regulatory standards.
