How Often Should I Pressure Wash My House, Driveway, Deck, and More?

Southern Oregon’s mix of rain, sun, and tree cover creates the perfect environment for moss, mildew, and grime to build up fast. Whether you own a home, manage rental properties, or sit on an HOA board, keeping exterior surfaces clean is more than just curb appeal—it protects your investment. So, how often should you pressure wash your house, deck, or other items? The answer depends on the surface, the weather, and how much wear and tear your property faces.

Why Regular Pressure Washing Matters

  • Preserves Paint and Stain: Dirt and mildew eat away at paint, siding, and deck stain, shortening the life of your finish.
  • Prevents Damage: Moss and algae can trap moisture, leading to rot and slippery walkways.
  • Protects Health and Safety: Regular washing removes allergens, pollen, and slippery buildup that can cause falls.
  • Boosts Property Value: Clean surfaces keep your property looking well-maintained, which is important to buyers and tenants.

Recommended Frequency by Surface

Southern Oregon’s Pacific Northwest climate – characterized by wet winters, dry summers, and abundant tree cover – necessitates a regular schedule. Here’s a short guide outlining how often you should power wash different surfaces:

House Siding

Wash every 1–2 years, or sooner if you see green streaks, mold, or pollen buildup. A gentle wash keeps paint fresh and protects wood or fiber cement. (National Home Improvement, Inc.)

Driveways & Walkways

Plan on once or twice a year, especially after winter, when moss and leaf debris leave slippery patches. (Driveway Company)

Decks & Fences

Give decks and fences a light wash annually, and a deeper clean before applying a new coat of stain or sealer. This prevents graying and helps stain adhere evenly. (Lowes)

Roofs

Soft wash every 2–3 years, or as soon as you notice moss or dark streaks. Avoid high-pressure cleaning to protect shingles—professionals use low-pressure methods and specialized solutions.

Other Surfaces1

Patios, retaining walls, and outdoor furniture can usually be cleaned as needed, but a yearly check keeps everything in shape.

Local Factors That Affect Timing

  • Rainfall & Shade: Properties surrounded by trees or in constant shade often need cleaning more frequently.
  • Pollen & Wildfire Smoke: Seasonal pollen and the occasional smoke from wildfires leave a sticky film.
  • HOA Standards: Many homeowners’ associations require periodic exterior cleaning.
  • Nearby Construction or Farming: Dust and debris can coat siding and hardscape faster.

Signs It’s Time to Power Wash

  • Green or black streaks on siding or shingles.
  • Slippery spots on walkways or decks.
  • Faded, dull, or chalky-looking paint.
  • You’re preparing to paint, stain, or put the property on the market.

Professional Pressure Washing VS. DIY

It’s tempting to rent a pressure washer, but the wrong nozzle or too much pressure can strip paint, gouge wood, or damage shingles. A professional crew:

  • Uses commercial-grade equipment and eco-friendly cleaners.
  • Knows how to match the right pressure and technique to each surface.
  • Saves you time and keeps you safely on the ground.

In the long run, the cost of professional power washing comes out to be less than repairing damage caused by DIY mistakes.
