DIY vs. Call a Pro
Consumer-grade pressure washers (1,500-2,000 PSI) work well for most residential tasks. Use a wide fan nozzle (25-40 degree) for siding, a turbo nozzle for concrete. Keep the nozzle 12-18 inches from surfaces. Never pressure wash windows, and use low pressure on wood to avoid damage.
Call a professional when:
Hire a professional for multi-story homes, soft-wash treatments for delicate surfaces, commercial-grade stain removal, roof cleaning, or when you lack equipment. Pros also carry liability insurance for accidental damage.
