Exterior power washing is a commercial cleaning method that uses pressurized water—combined with heat and surface-specific detergents—to remove grease, oil, salt residue, algae, soot, and environmental pollutants from building exteriors and hard surfaces.
What Exterior Power Washing Removes
- Grease and oil contamination
- Soot and airborne pollution residue
- Salt and de-icing chemical buildup
- Mold, algae, and mildew growth
- Embedded dirt in concrete and masonry
Service Scope
- Building facades: brick, stone, stucco, metal panels
- Storefronts and entryways
- Sidewalks and pedestrian walkways
- Parking lots and loading zones
- Dumpster pads and waste containment areas
- Drive-thru lanes and service corridors
- Exterior walls near kitchen exhaust discharge
Compliance Requirements — Chicago
Commercial properties must maintain exterior cleanliness to reduce public health risk and prevent sanitation violations.
Enforcement and standards:
- Chicago Department of Public Health — sanitation enforcement and inspection authority
- NFPA — fire risk standards related to grease accumulation
Non-compliance exposure:
- Failed inspections
- Monetary penalties
- Increased fire risk in grease-affected zones
- Operational disruption
Method Selection (Surface + Contamination Mapping)
Exterior Power Washing Process (Step Sequence)
- Site Assessment
Identify surfaces, contamination levels, drainage flow, and risk zones - Preparation
Protect electrical fixtures, entrances, landscaping, and pedestrian areas - Pre-Treatment
Apply degreasers or detergents to grease and biological buildup - Cleaning Execution
Adjust pressure and temperature per surface and contamination - Runoff Control
Contain and redirect wastewater to avoid environmental contamination - Final Inspection
Verify contaminant removal, surface integrity, and compliance readiness
When Exterior Power Washing Is Required
- Grease accumulation around dumpsters or rear service areas
- Darkened sidewalks caused by high foot traffic and pollution
- Mold, algae, or mildew growth on exterior surfaces
- Salt residue buildup after winter conditions
- Pre-inspection preparation for restaurants and commercial properties
- Post-construction or renovation cleaning
Chicago Operating Conditions
- Winter de-icing salts accelerate staining and surface degradation
- High-density traffic corridors increase soot accumulation
- Restaurant zones produce grease runoff affecting adjacent surfaces
- Seasonal humidity promotes biological growth on shaded facades
Result: higher cleaning frequency compared to low-density markets.
Service Frequency Model
Area | Frequency Range |
Restaurant exteriors | Monthly / Bi-monthly |
Sidewalks and entryways | Monthly |
Dumpster pads | Weekly / Bi-weekly |
Commercial building facades | Quarterly / Semi-annual |
Parking lots and drive lanes | Quarterly |
Frequency is determined by contamination intensity and inspection risk.
Operational Outcomes
- Removal of grease, oil, and embedded contaminants
- Reduction of slip hazards on pedestrian surfaces
- Improved commercial appearance and tenant perception
- Lower probability of sanitation violations
- Reduced fire risk in grease-exposed exterior zones
Power Washing vs Pressure Washing
- Power washing: uses heated water to break down grease and organic material
- Pressure washing: uses unheated water for general cleaning
Application rule: grease-contaminated commercial surfaces require heated power washing.

FAQ
How often should exterior power washing be performed in Chicago?
Monthly for high-traffic or grease-exposed properties. Quarterly for low-exposure buildings.
Does exterior power washing remove grease stains?
Yes. Hot water and degreasing agents break down oil bonds and enable full removal.
Is exterior cleaning required for restaurants?
Yes. Exterior conditions impact sanitation inspections and compliance outcomes.
Can all surfaces be power washed?
No. Pressure and method are adjusted. Soft washing is required for delicate materials.
What happens if exterior areas are not maintained?
Grease and contamination increase the likelihood of violations, fines, and operational disruption.

Frequently Asked Questions
What is power washing?
Power washing uses high-pressure water to clean surfaces like driveways, decks, siding, and patios. It removes dirt, mold, algae, and grime that regular cleaning can’t.
What surfaces can you power wash?
We safely clean wood decks, concrete driveways, brick, stone, siding, fences, and more. Almost any exterior surface can be restored with professional power washing.
Is power washing safe for my home?
Yes! Our team uses professional-grade equipment and techniques tailored to each surface. We remove dirt and mold without causing damage.
How often should I power wash my property?
Most homes benefit from power washing once a year. High-traffic areas or homes in humid climates may need it more often to prevent mold and stains.
