The Buy vs. Hire Question
Every Oregon homeowner thinks about it: "Should I just buy a pressure washer and do this myself?" It's a reasonable question. But the answer depends on how often you'd actually use it, what you need it for, and whether consumer-grade equipment can handle Oregon's specific challenges.
Consumer Pressure Washer Performance
Home Depot and similar stores sell electric and gas pressure washers in the 1,500–3,000 PSI range for $300–$800. These work fine for:
- Light driveway maintenance
- Washing cars and RVs
- Cleaning patio furniture
They are not adequate for heavy moss removal, oil stain elimination, or large-scale surface cleaning. And they lack hot-water capability — which is critical for grease and biological growth.
Commercial Equipment: What Professionals Use
Professional crews use hot-water pressure washers in the 2,500–4,000 PSI range with water heating capability (140–180°F). These machines cost $3,000–$8,000+ and require maintenance. They deliver dramatically better results on hard stains and biological growth.
The ROI Calculation
Buying a consumer washer: $500 upfront. Works for light jobs. For heavy cleaning, you'll still need to hire a professional.
Hiring professional service: $100–$300 per job. Commercial equipment, proper technique, and guaranteed results.
If you pressure wash your driveway once per year (which is the typical Oregon maintenance schedule), hiring is cheaper than buying AND maintaining a machine over 3–5 years.
The Verdict
For light, occasional use (car washing, small patio), a consumer pressure washer is a fine investment. For anything involving your home's exterior surfaces — driveways, walkways, siding — hiring a professional with commercial equipment delivers better results at a comparable or lower total cost.
