Safety first (especially for 2 stories)

  • Avoid using a ladder with a pressure washer whenever possible.

  • Use an extension wand or telescoping wand for upper levels.

  • Wear eye protection and non-slip footwear.

  • Keep the spray away from electrical fixtures and cover outlets.

  • Never spray upward under lap siding or into vents/soffits.

Recommended setup

  • 40° (white) nozzle for rinsing and gentle cleaning

  • Soap nozzle (black) for applying detergent

  • House-wash detergent (siding-safe)

  • Extension wand / telescoping wand

  • Garden hose for pre-wet and plant protection

Step-by-step: how to power wash a 2-story house

  • Pre-wet plants and cover outlets, lights, and sensitive areas.

  • Apply detergent from bottom to top (prevents streaking).

  • Let soap dwell 5–10 minutes (don’t let it dry).

  • Rinse from top to bottom using smooth, overlapping passes.

  • Keep distance (start 3–4 feet away) and use the lowest pressure that works.

  • For the second story, use an extension wand and keep the spray angle downward.

Common mistakes to avoid

  • Using too much pressure on siding or trim.

  • Spraying upward and forcing water behind siding.

  • Standing on a ladder while spraying.

  • Letting detergent dry on the surface.

  • Getting too close around windows and seals.

When to hire a pro

If your home is tall, has delicate siding, or you’re unsure about safe access, hiring a professional can prevent damage and reduce risk.
