If you manage a commercial property in Connecticut and you are trying to budget for cleaning, the first question is almost always the same: what does this actually cost per square foot? The answer is genuinely “it depends,” but the range is narrower than the internet would have you believe, and the variables that move the price are predictable.
We have written this guide as a working answer for property managers, business owners, and facility leads who are tired of being told “it depends” and want a real number to work from. The figures below reflect what commercial cleaning actually costs in southeastern Connecticut and Rhode Island in 2026.
The short answer: $0.07 to $0.25 per square foot, per cleaning
For most general-office commercial cleaning in our service area, expect to pay between seven cents and twenty-five cents per square foot per cleaning. Where you fall in that range depends on five factors:
1. Frequency. Nightly service costs less per visit than weekly, because the work is lighter each time. A 5,000 sq ft office cleaned five nights a week typically runs $0.07–$0.10 per square foot per cleaning. The same space cleaned once weekly might be $0.15–$0.20 because each visit involves more accumulated work.
2. Type of space. Standard office is the baseline. Medical and dental practices run 30–60% higher because of disinfection and OSHA-related protocols. Industrial common areas are similar to office. Restaurants, kitchens, and food-service spaces are a different conversation entirely and usually quoted as separate scopes.
3. Floor type and finish. Carpeted offices are simpler and cheaper. VCT tile, polished concrete, and hardwood need periodic strip-and-wax or burnishing, which adds either to the line-item or to the per-square-foot rate.
4. Restroom count and traffic. Restrooms are the most labor-intensive part of any building. A property with a high restroom-to-square-footage ratio (medical, retail, education) prices higher than a property with the same square footage but fewer restrooms.
5. Specifications and standards. A “broom-clean” scope is dramatically less expensive than a detailed scope including dusting, glass cleaning, microfiber-only protocols, and trash separation. The scope drives the price more than any other single factor.
Real-world examples from our service area
To give you working numbers from buildings we actually clean:
A 4,200 sq ft professional office in Groton cleaned three nights per week: roughly $1,400/month, which works out to about $0.027 per square foot per cleaning across 12 visits. That is on the low end because the building is well-maintained, the occupancy is low-traffic, and the floors are mostly carpet.
A 9,500 sq ft medical office in New London cleaned five nights per week: roughly $4,600/month, or $0.044 per square foot per cleaning. The medical-grade scope and the high restroom count drive the rate up despite the larger footprint.
A 22,000 sq ft multi-tenant office building in Hartford with day porter coverage plus nightly cleaning: roughly $11,800/month combined. Day porter is a fixed cost regardless of square footage; nightly cleaning is approximately $0.034 per square foot.
What you should be wary of
Quotes substantially below $0.07 per square foot per cleaning for ongoing nightly office work in this market should make you ask questions. Either the scope is being trimmed in ways that will create problems six months in (rotating tasks, missed restrooms, inadequate supplies), or the contractor is paying labor rates that mean turnover and quality issues. Cleaning is a labor business, and labor is the same price whether you bid it in or hide it.
Quotes substantially above $0.25 per square foot per cleaning for general office work usually mean either the scope is unusually demanding (you should know what you are buying), or the company is overhead-heavy in a way that does not translate into better service.
How to use these numbers
Multiply your square footage by a midpoint rate (say $0.10 per square foot per cleaning) by your weekly frequency by 4.3 weeks. That gives you a working monthly budget figure. Use it to sanity-check quotes you receive.
Example: a 6,000 sq ft office cleaned 4 nights per week. 6,000 × $0.10 × 4 × 4.3 = $10,320 per month. That is roughly the upper bound. A reasonable bid range from a good contractor would be $1,800–$2,800/month for that space.
Frequently asked questions
How much does commercial cleaning cost per square foot in Connecticut?
Most general-office commercial cleaning in Connecticut runs between $0.07 and $0.25 per square foot per cleaning. Where you fall in that range depends on frequency, scope, type of space, floor type, and restroom count.
What factors affect commercial cleaning pricing?
Five main factors: cleaning frequency (more frequent = lower per-visit cost but higher monthly), type of space (medical or industrial vs standard office), floor type and finish (carpet vs VCT vs hardwood), restroom count and traffic, and scope details (broom-clean vs detailed scope).
Why does medical office cleaning cost more than standard office cleaning?
Medical office cleaning typically runs 30 to 60 percent higher than standard office work. The reason: more time per visit (the protocols take longer), better products (hospital-grade disinfectants cost more), more crew training, and more documentation. If a contractor quotes you the same rate as standard office work for a medical facility, they either don’t understand the standards or will cut corners.
How can I estimate my commercial cleaning budget?
Multiply your square footage by a midpoint rate ($0.10 per square foot per cleaning), by your weekly frequency, by 4.3 weeks. For example, a 6,000 square foot office cleaned 4 nights per week would be 6,000 × $0.10 × 4 × 4.3 = $10,320 per month upper bound. A reasonable bid range from a good contractor would be $1,800 to $2,800 per month for that space.
What does it mean if a quote is below $0.07 per square foot?
Quotes substantially below $0.07 per square foot per cleaning for ongoing nightly office work in Connecticut are a red flag. Either the scope is being trimmed in ways that will create problems six months in (rotating tasks, missed restrooms, inadequate supplies), or the contractor is paying labor rates that mean high turnover and quality issues. Cleaning is a labor business, and labor costs the same whether you bid it in or hide it.
Are quotes above $0.25 per square foot reasonable for commercial cleaning?
For unusually demanding scopes (medical, executive-floor service, complex multi-tenant coordination), yes. For standard office work, quotes substantially above $0.25 per square foot per cleaning usually indicate either an unusual scope you should understand fully, or a contractor with overhead that doesn’t translate into better service.
