When Was the Last Time You Looked at Your Building From the Street?
Drive past your property tomorrow like a first-time visitor would. See those dark stains on the sidewalk? The green film creeping up the north wall? The oil spots in the guest parking? That's your first impression — and it's being made before anyone walks through the door.
When to Pressure Wash
| Surface | Frequency | Signs It's Overdue |
|---|---|---|
| Sidewalks | Quarterly | Dark staining, gum buildup |
| Building exterior | Semi-annually | Green algae, streaking |
| Parking garage | Semi-annually | Oil stains, tire marks |
| Dumpster area | Monthly | Odor, pest attraction |
| Loading dock | Quarterly | Grease and debris |
EPA Compliance
Pressure washing runoff is regulated. You can't just wash chemicals and debris into storm drains. Your provider should:
- Use biodegradable detergents
- Capture or redirect wash water
- Document compliance per local regulations
What It Costs
| Area | Cost Range |
|---|---|
| Sidewalk (per 1,000 sqft) | $80-$150 |
| Building exterior (per story) | $300-$800 |
| Parking lot (per 1,000 sqft) | $50-$100 |
