Pressure Washing Cost Per Square Foot for Contractors
Square-foot pricing is useful, but contractors should treat it as one input inside a cost, minimum fee, and margin workflow.
Quick answer
Use cost per square foot as a market and area check, not as the entire quote. Before sending a customer price, compare the square-foot result against labor, materials, travel, setup, overhead, minimum job price, and target margin.
Why square-foot pricing can be misleading
| Situation | Why area price can fail | What to add |
|---|---|---|
| Small job | Area price may not cover trip and setup | Minimum job price |
| Heavy staining | More chemical, dwell time, and rinse work | Material and labor allowance |
| Difficult access | More setup, safety risk, and cleanup | Access multiplier |
| Long travel | Fuel and labor time rise before cleaning starts | Travel fee |
