Supporting Montgomery County's Diverse Commercial Properties
Montgomery County is home to one of the most diverse commercial markets in Maryland. From corporate headquarters and biotechnology campuses to shopping districts, hospitals, educational institutions, and mixed-use developments, every property requires a cleaning strategy tailored to its environment.
High-rise office buildings accumulate airborne pollutants and organic staining.
Retail centers see heavy pedestrian traffic that leaves sidewalks, entrances, and storefronts looking worn.
Healthcare campuses require careful scheduling to minimize disruptions while maintaining clean, welcoming facilities.
Industrial and warehouse properties often need heavy-duty concrete cleaning, loading dock washing, and exterior maintenance that keeps operations running efficiently.
City Clean understands these varying environments and develops customized cleaning solutions for each property we service.
Choosing the Right Cleaning Method
Not every surface should be cleaned with high pressure. Our technicians evaluate every project before work begins to determine the safest and most effective cleaning process.
Power Washing
Power washing is ideal for durable surfaces including:
- Concrete
- Brick
- Parking lots
- Curbs
- Sidewalks
- Loading docks
Soft Washing
Soft washing is used on more delicate materials such as:
- Stucco
- EIFS
- Vinyl siding
- Painted surfaces
- Decorative masonry
- Exterior trim
By selecting the appropriate cleaning method, we safely remove dirt, mold, algae, mildew, and staining while protecting your building's exterior.

Commercial power washing is more than improving appearance.
Routine exterior maintenance helps:
