How Often Should You Pressure Wash Your Home in the Central Valley?

Families across the Central Valley ask the same question every year:

“How often should I pressure wash my home?”

The answer isn’t “once in a while.”
It depends on:

• Local weather

• Air quality

• Shade level

• Dust exposure

• Landscaping

• Moisture

• Pollution

If you live in Lodi, Stockton, Manteca, Modesto, Elk Grove, Valley Springs, Jackson, Angels Camp, or Salida, here’s the EXACT washing frequency your home needs for proper maintenance.

1. Homes in Lodi, Stockton, Manteca, Modesto, Elk Grove

Recommended: Every 9–12 Months

Why?

• Heavy dust

• Pollen

• Traffic film

• Heat oxidation

• Sprinkler overspray

• Hard water stains

These cities are high-traffic and often windy, meaning buildup happens faster.

2. Homes in Valley Springs, Angels Camp, San Andreas, Jackson, Copperopolis

Recommended: Every 6–9 Months

Why?

• More shade

• More trees

• More moisture

• Faster algae growth

• Cooler temperatures

These areas grow green staining and mold faster.

3. Homes Near Trees or Shade Anywhere

Recommended: Every 6–8 Months

Shaded areas trap moisture, causing mold and mildew to grow quickly.

4. Homes Along Busy Roads (99, I-5, Hwy 4)

Recommended: Every 6–10 Months

Traffic film and pollution constantly coat siding.

5. Homes with Light Siding (White, Beige, Cream)

Recommended: Every 6–9 Months

Light colors show dirt and algae more clearly.

Conclusion

The Central Valley’s mix of heat, dust, pollen, hard water, shade, and traffic makes yearly pressure washing a must. Some homes even require bi-annual cleaning.

Keeping your home on the right cleaning schedule protects:

✔ Curb appeal
✔ Paint
✔ Stucco
✔ Wood
✔ Concrete
✔ Roof surfaces

If it's been close to a year since your last cleaning — your home is due.
