How often you should pressure wash depends on several factors. Here’s a general guide:

• Exterior walls: Once a year. More often if you live in a humid or dusty area.

• Driveways and sidewalks: Every 6 months, since they collect grease, dirt, and tire marks.

• Roofs and gutters: Every 1–2 years, especially if there’s mold or algae growth.

• Commercial properties: Every 3–6 months to maintain a clean, professional appearance.
