Pressure Washing Your Commercial Property After Florida's Rainy Season
Published · By Empire FL Professional Cleaning

Central Florida's rainy season usually runs from about June through October. Months of afternoon storms, heat, and humidity leave their mark on the outside of a commercial property: dark streaks on walls, a green film on shaded walkways, and stains around entrances and dumpster enclosures. By the time the weather turns drier, the outside of a building often looks more worn than the inside.
For facility managers, dealership general managers, school and church administrators, and office managers, fall is a practical time to plan exterior cleaning. The heaviest rain is usually behind you, the Atlantic hurricane season officially ends on November 30, and the busiest visitor weeks of the year are still ahead. This guide covers what to look for, where commercial pressure washing usually matters most, and how to prepare for a site visit.
What the rainy season leaves behind
Humidity, standing water, and shade give mildew, mold, and algae a chance to grow on exterior surfaces. After a long wet summer, walk your property and look for:
- Dark spots or streaks on stucco, block walls, and painted surfaces, especially on the shaded sides of the building
- Green or black film on sidewalks and walkways that stay damp
- Dirt splashed onto lower walls, columns, and planters
- Runoff marks and stains below rooflines and downspouts
- Grease, food residue, and buildup around dumpster pads
- Gum, tire marks, and grime at busy entrances and in drive lanes
Some of this is purely cosmetic. Some of it changes how a walkway looks and feels underfoot. Either way, visitors usually notice a grimy entrance before they ever walk through the door.

Where to focus first
Not every surface needs the same attention. Most commercial properties get the most visible results from these areas.
Entrances and entryways
The entrance is the first impression for customers, parents, congregants, and staff. Look at the walkway leading to the door, the area under awnings and canopies, and any columns or planters near the entry. Dirt from outside also gets tracked in, which is one reason exterior and interior floor care often go together. If your lobby has tile, our tile and grout cleaning service covers the inside of the same entryway.
Sidewalks, walkways, and concrete flatwork
Long runs of concrete, such as sidewalks along the street, walkways between buildings, and covered breezeways, collect mildew and dirt in the areas that stay shaded and damp. These surfaces often show the clearest difference between cleaned and uncleaned sections.
Dumpster pads and grease-stained areas
Dumpster enclosures collect grease, spilled food, and residue, especially behind restaurants, cafeterias, break rooms, and church kitchens. They are easy to forget because few visitors see them, but they are often the dirtiest concrete on the property. Many facilities clean them more often than the rest of the exterior.

Building exteriors and facades
Mildew streaks on walls and facades show up from the parking lot and the street. Exterior walls need a careful approach because stucco, paint, and other finishes can react differently to water pressure and cleaning solutions.
Parking areas and drive lanes
Drive lanes, drop-off areas, and parking spaces near the entrance collect oil spots, tire marks, and debris. For dealerships and schools in particular, these areas get a lot of traffic.
What different facilities should consider
Car dealerships
Showroom entrances, customer parking, and service drive lanes all shape how a dealership looks to shoppers. With year-end sales events coming up in November and December, fall is a good time to clean the areas customers walk and drive through. That applies to a showroom on US-192 in Kissimmee or Highway 50 in Ocoee.
Schools
Walkways, courtyards, drop-off loops, and cafeteria dumpster areas see heavy daily use. Many schools prefer exterior work when students are not on campus, such as weekends or the Thanksgiving and winter breaks. Administrators in Clermont and Lakeland can plan exterior work alongside interior floor projects such as floor strip and wax.
Churches
Advent and Christmas bring some of the busiest weeks of the year for many congregations. Entrances, covered walkways, courtyards, and parking areas set the tone for visitors before services begin. Churches in Windermere and Winter Garden can plan exterior cleaning ahead of the holiday calendar.
Offices and multi-tenant buildings
Office buildings usually focus on main entrances, sidewalks, and shared dumpster enclosures. Property and office managers in Orlando, Winter Park, and Apopka often schedule exterior work outside business hours, so tenants and visitors are not disrupted.
Commercial pressure washing is not one-size-fits-all
Concrete, pavers, stucco, painted walls, and storefront areas respond differently to water pressure and cleaning products. A method that suits a concrete sidewalk may be wrong for a painted wall or older stucco.
Through our commercial pressure washing service, Empire assesses each surface and its condition, selects an appropriate cleaning method, and discusses any limitations before work begins. Where mold, mildew, or grease needs to loosen first, cleaning solutions are applied before washing, and nearby areas are protected. When the work is done, we walk the area with you to review it.
It also helps to set realistic expectations. Results depend on the surface, the type of buildup, and how long it has been there. Some older stains may lighten rather than disappear completely. Whichever provider you use, ask how they will approach each surface and how they will work around landscaping, parked vehicles, and entrances. Our guide on how to choose a commercial cleaning company covers other questions worth asking.
Why October and November work well
- The wettest months are usually behind you. Fewer afternoon downpours make outdoor work easier to schedule.
- The holidays are ahead. Thanksgiving, year-end sales events, Christmas services, and school events bring more visitors to many properties.
- Hurricane season ends November 30. If a late-season storm passes through, inspect your exterior again afterward and schedule a follow-up wash if debris or new staining appears.
How often should you plan exterior cleaning? In Central Florida, most commercial exteriors benefit from a wash once or twice a year because of the humidity and mildew. High-traffic entrances and dumpster areas may need it more often. A fall wash after the rainy season, plus a second wash in spring before the wet months return, is one simple way to plan the year.
Add exterior work to your cleaning scope
Pressure washing is usually a periodic service, separate from routine interior cleaning. In What Is Included in Commercial Cleaning?, we explain how to separate recurring tasks from periodic and specialty work so nothing is assumed. If you are comparing proposals, How Commercial Cleaning Pricing Works in Central Florida explains why the quote depends on the surfaces, their condition, and the scope rather than a single standard rate.
Exterior cleaning fits alongside your recurring commercial cleaning schedule. Our guide on how often an office should be cleaned covers the interior side of that planning.
