How to Clean Commercial Building Exteriors?
Auburn, WA–where frequent rainfall, damp conditions, and seasonal shifts encourage dirt buildup, organic growth like moss or mildew formation, and seasonal variations–making its exterior clean not just an aesthetic decision; rather, it serves a greater purpose: protecting materials, prolonging property lifespan, and upholding professional image.
This guide describes the methods and factors involved in cleaning commercial building exteriors in Auburn’s climate, and why professional cleaning is often the safest and most efficient option.
Why Exterior Cleaning Matters for Commercial Buildings
Over time, building exteriors inevitably accumulate dirt, grime, mold, and algae growth – especially in Auburn’s climate, where shaded surfaces or those exposed to moisture become especially susceptible. Regular exterior cleaning offers several advantages:
- Enhanced Curb Appeal: A clean building exterior projects professionalism and attracts customers and tenants.
- Preventative Maintenance: Removing mold, mildew, and algae prevents long-term damage to materials.
- Health and Safety: Cleaner surfaces reduce allergens and slippery walkways caused by organic buildup.
- Property Value Preservation: Routine cleaning helps extend the lifespan of siding, brick, glass, and other exterior surfaces.
Professional Cleaning Methods
The proper cleaning method depends on the building material, level of contamination, and the desired finish. Typical approaches used in Auburn include:
1. Pressure Washing
- Uses high-pressure water streams to blast away dirt, pollen, and debris.
- Works well for durable surfaces such as concrete, brick, or stone.
- Must be carefully calibrated—too much pressure can damage paint, siding, or softer materials.
2. Soft Washing
- Uses low-pressure water combined with specialized cleaning solutions.
- Ideal for delicate surfaces like vinyl siding, stucco, or painted finishes.
- Effective at killing and removing mold, mildew, and algae at the root level, preventing regrowth.
3. Chemical Cleaning
- This process involves applying carefully selected cleaning agents to break down stains or organic buildup.
- Solutions are matched to the surface type—glass, metal, or stone—to avoid damage.
- Often used for stubborn staining or surfaces requiring a streak-free finish.
Key Considerations for Auburn Commercial Buildings
Every building requires a tailored approach to cleaning. For Auburn specifically, these factors play an essential role:
- Local Climate: The Pacific Northwest’s wet environment encourages moss, algae, and mildew growth, especially on north-facing walls or shaded areas.
- Building Materials: Brick, vinyl, metal, and glass all require different cleaning techniques to avoid streaking or damage.
- Height and Access: Multi-story buildings may require specialized equipment such as water-fed poles, scaffolding, or rope access for high-rise cleaning.
- Environmental Responsibility: Many cleaning services in the area now use eco-friendly detergents to protect landscaping, nearby waterways, and air quality.
Professional vs. DIY Cleaning
For small residential properties, DIY cleaning may be manageable. But for commercial buildings in Auburn, professional services are almost always the better option.
- Stained glass and screens
- Traps moisture in wooden frames
- Accelerates rust on metal frames
- Damages seals and caulking
3. Chemical Cleaning
- Safety: Professionals are trained and equipped to work at heights and handle specialized tools.
- Efficiency: Large areas can be cleaned faster and more thoroughly with professional-grade equipment.
- Expertise: Technicians know which methods and cleaning agents are safe for different building materials.
- Consistency: A professional cleaning ensures a streak-free, uniform finish.
DIY Cleaning Limitations
- Access Issues: Tall buildings or hard-to-reach surfaces make DIY cleaning unsafe.
- Risk of Damage: Using excessive water pressure or the wrong solution can cause permanent damage to siding or glass.
- Time and Labor: Cleaning a large building is labor-intensive without professional tools.
Setting Up a Cleaning and Maintenance Plan
Rather than waiting for the buildup to become noticeable, many Auburn businesses opt for routine cleaning schedules. A professional maintenance plan might include:
- Annual or Semi-Annual Washing: Helps manage mold and algae growth in a damp climate.
- Window Cleaning Cycles: For buildings with large glass facades, seasonal cleanings maintain a clear, professional look.
- Surface Protection Treatments: Some services apply protective coatings to slow down staining and algae regrowth.
- Walkway and Entry Cleaning: Maintains safe and appealing entrances for staff and visitors.
