A good commercial cleaning contract in Miami is built around moisture first. Heat and humidity never really leave, so mold prevention, restroom detailing and wet entrances belong in the base scope, not in a list of extras. The other two things to plan for are the calendar (storm season runs into late November, and the dry winter months bring the heaviest visitor traffic of the year) and the district, since a Brickell tower and a Doral warehouse need very different crews.
Where the work is in Miami-Dade
Most of the region's high-rise office space sits in Brickell and Downtown Miami, where financial firms, law offices and corporate tenants share towers with residential and hotel floors. Coral Gables has a dense mix of corporate offices, consulates and professional practices. Wynwood and the Design District have turned older industrial buildings into creative offices, showrooms and restaurants. West of the airport, Doral and the corridors around Miami International Airport hold a large share of the county's warehouses and freight forwarders, many of them tied to trade with Latin America and the Caribbean.
For cleaning, that means two very different markets. Tower work is about lobbies, elevators, restrooms, glass and building rules: freight elevator bookings, badge access, after-hours windows set by property management. Warehouse work is about slab scrubbing, dock areas, driver lounges and offices attached to the building. Many contractors are strong in one and thin in the other, so ask each bidder which of your building types makes up most of their current work in the county.
Humidity, mold and water at the door
Miami's climate changes the scope in a few predictable ways:
- Mold and mildew control. Grout lines, shower and locker areas, janitor closets, ceiling diffusers and the corners behind doors collect moisture. Ask how often these are detailed, which products are used, and how the crew reports visible growth (cleaning surface mildew is janitorial work; anything behind walls or in ductwork is a remediation job for a different trade).
- Condensation from air conditioning. Cold supply air meeting warm glass and humid entrances leaves wet spots near vents, windows and lobby doors. Floors there need more frequent dry mopping and clear wet-floor signage.
- Afternoon downpours. Summer storms come fast and leave entrances soaked. Mat service, extra mopping at the doors and a plan for parking garage stairwells and elevator lobbies keep slip risks down.
- Sand. Buildings near Miami Beach, Key Biscayne and the waterfront track in sand year-round. It wears hard floors and fills carpet, so entrance matting and vacuum frequency matter more than in inland suburbs.
Storm season and high season
The Atlantic hurricane season runs from June 1 to November 30. A useful contract says what the cleaning provider does before and after a named storm: securing or removing supplies stored on site, helping clear loose items from terraces and loading docks if that is in scope, and a post-storm cleanup visit for debris, muddy entrances and water tracked into lobbies. Write down how those visits are priced and how quickly the crew can come back once roads reopen. Water extraction, drying equipment and anything involving flood damage are restoration work, so confirm whether the contractor offers it or refers it out.
From December through April the region fills with seasonal residents, tourists, conventions and art-season events. Retail, hospitality, medical offices and mixed-use lobbies see much heavier foot traffic, which means more restroom checks, more trash pulls and faster wear on floors. If your building is busy in those months, price a day porter or extra restroom rounds for the season instead of hoping the nightly crew keeps up.
What each building type usually needs
Brickell and Downtown offices. Nightly trash and recycling, restroom cleaning and restocking, kitchen and break room cleaning, vacuuming and spot cleaning of interior glass. Many towers add a day porter for lobbies and restrooms. Marble and terrazzo lobbies need a scheduled polishing or refinishing program, which is specialty work priced separately.
Doral and airport-area warehouses. Ride-on scrubbing of the warehouse floor, dock and staging area sweeping, high dusting of racking and structure on a set cycle, plus the attached offices and driver areas. Ask whether the contractor brings its own scrubber.
Medical and dental clinics. Exam and treatment room turnover, touch-point disinfection with products that match your infection control policy, and clear limits on biohazard and sharps waste, which should go to a licensed medical waste hauler, not the janitorial crew.
Retail and restaurants in Wynwood and the Design District. Early-morning or overnight cleaning around late business hours, frequent restroom service, and grease and degreasing work in back-of-house areas.

Typical price ranges
These are typical ranges, not quotes. Square footage, frequency, floor types, restroom count, access rules, and the amount of day porter or specialty work all move the number.
- Routine office cleaning, five nights a week: often about $0.09 to $0.22 per square foot per month for larger offices, with small suites usually billed as a flat monthly fee.
- Day porter service: commonly $26 to $45 per hour, depending on hours and duties.
- Floor care (stone polishing, strip and wax, carpet extraction): priced per square foot per visit and heavily dependent on the floor's condition.
- Storm cleanup visits and high-season extras: best priced as fixed add-ons in the contract so there is no surprise invoice in a busy week.
Labour is the biggest part of any cleaning price, and Florida's minimum wage rose to $15 an hour on September 30, 2026, completing the schedule voters approved in 2020. Bids written before that date may be priced too low to hold. For a rough figure on your own space, try the pricing calculator, then send every bidder the same written scope so the quotes compare like for like.
Paperwork to collect before you sign
Florida does not issue a state license specifically for janitorial contractors, so the documents you ask for do the screening. Request a certificate of general liability insurance naming your company or property as additional insured, and proof of workers' compensation coverage (Florida requires it for most non-construction employers with four or more employees). Businesses in Miami-Dade generally hold a county local business tax receipt, plus a city one where the city requires it. Private workplaces in Florida fall under federal OSHA, so ask for hazard communication training records and safety data sheets for every product used in your building, and for bloodborne pathogens training if the crew cleans clinics or restrooms with that exposure.
Frequently asked questions
How much does commercial cleaning cost in Miami?
For larger offices on a five-night schedule, typical pricing often runs from about $0.09 to $0.22 per square foot per month. Small suites are usually billed as a flat monthly fee. Day porters, floor care and storm or high-season add-ons are priced on top.
Do janitorial companies in Florida need a state license?
No, Florida has no state license specific to janitorial work. Contractors still need local business tax receipts where they operate, and you should ask for proof of general liability insurance and workers' compensation before they start.
Should a Miami cleaning contract include hurricane cleanup?
It should at least define it. Spell out what the crew does before a named storm, when a post-storm visit happens, and how it is priced. Flood damage and water extraction are restoration work, so confirm whether the contractor handles them or refers them to a specialist.
When do Miami buildings need extra cleaning during the year?
Plan for the December to April high season, when visitors, seasonal residents and events bring the heaviest foot traffic, and for the summer rainy season, when entrances and garages stay wet. Both are easier to manage as priced add-ons than as last-minute requests.
