Power washing your house can feel like giving it a fresh coat of life. Everything just looks better when it’s clean. But how often should you actually do it? Every year? Every five years? The answer depends on several factors, from where you live to how exposed your home is.
📅 The General Rule
Most homeowners should plan to power wash their home once every 12 to 18 months. This frequency helps remove:
- Mold and mildew 🌫️
- Dirt and dust 🧹
- Bird droppings and insect residue 🐦🐛
- Pollen and allergens 🌼
But this rule isn’t one-size-fits-all.
🌎 Climate and Location Matter
- Humid or Rainy Areas:
If you live somewhere with lots of rain or high humidity, mold and mildew can grow quickly. In these cases, once a year—or even twice—might be necessary. - Dry or Dusty Areas:
If you’re surrounded by dust or sand (hello, desert dwellers! 🌵), you might need to wash more frequently to keep buildup at bay. - Tree-Covered Homes:
Homes shaded by trees tend to attract mildew, falling sap, leaves, and bird droppings. That might mean more frequent cleanings.
🧱 Surface Material Makes a Difference
- Vinyl Siding: Once a year is usually fine.
- Brick or Stucco: Can go longer between washes—closer to every 2–3 years—if well maintained.
- Wood: Needs a gentle touch and possibly more frequent cleaning to prevent decay.
👀 Signs It’s Time for a Wash
Not sure if it’s time yet? Look out for:
- Green patches (mold or algae)
- Streaks of black (dirt buildup or mildew)
- Dull color or chalky residue
- Increased allergy symptoms indoors
If you see any of these signs, it’s probably time to schedule a wash.
🧼 Regular Cleaning Pays Off
Keeping your house clean isn’t just about looks—it’s also about maintenance. Regular power washing helps prevent damage from mold, pests, and buildup. That means fewer repairs and a longer-lasting exterior.
💡 Bonus Tip: Power wash before you repaint! It’ll give you a cleaner surface to work with, which helps the paint stick better and last longer.
