Your home faces the elements every day—rain, dirt, pollen, mold, bird droppings, and air pollution all gradually build up. While a single professional pressure wash can refresh your exterior, regular cleanings are key to maintaining long-term beauty and protecting your surfaces.

But how often should you pressure wash your home? The answer depends on a few important factors.

General Rule of Thumb: Once a Year

Most homeowners benefit from scheduling a professional pressure washing once per year. This keeps dirt and organic growth from taking hold, maintains your home’s curb appeal, and extends the life of paint and siding.

Factors That May Require More Frequent Cleanings

1. Climate and Weather

If you live in a humid or rainy region, you’re more likely to deal with mold, algae, and mildew buildup. Homes in these areas may need to be pressure washed every 6–8 months.

2. Surrounding Trees or Landscaping

Overhanging trees can drop sap, leaves, and pollen on your roof and siding. Bushes close to the home also trap moisture. If your landscaping creates more debris, it’s a sign to clean more often.

3. Visible Staining or Discoloration

Dark streaks, green patches, or chalky residue are signs of algae, mold, or oxidation. These are not just cosmetic—they can deteriorate your surfaces if ignored.

4. HOA or Property Requirements

Some neighborhoods or homeowners’ associations require homes to be pressure washed regularly to maintain a clean community appearance.

Areas of the Home That May Need More Frequent Attention

• Driveways and Sidewalks – 1–2 times per year
• Decks and Patios – Every 6–12 months depending on usage
• Roofs – Every 2–3 years (soft washing preferred)
• Gutters and Fascia – Annually, especially after fall
• Home Siding – Annually or biannually depending on exposure

The Benefits of Staying Consistent

• Prevents permanent staining
• Stops mold and algae before they spread
• Boosts curb appeal year-round
• Extends the lifespan of your paint, siding, and concrete
