Pressure Washing Do's and Don'ts for Homeowners

Pressure Washing: Powerful but Potentially Dangerous

Pressure washing can transform dirty surfaces, but improper technique can cause serious damage. Whether you're DIYing or hiring a professional, here's what you need to know.

Understanding Pressure Settings

PSI (Pounds per Square Inch)

Different surfaces require different pressures:

The Do's of Pressure Washing

Do Test First

• Start with lowest pressure
• Test in an inconspicuous area
• Gradually increase if needed

Do Keep Your Distance

• Start 2-3 feet away
• Move closer gradually
• Maintain consistent distance

Do Use Proper Technique

• Work in smooth, overlapping strokes
• Follow the direction of the grain (for wood)
• Work from top to bottom
• Rinse thoroughly

Do Protect Yourself and Surroundings

• Wear safety glasses and closed-toe shoes
• Cover plants and landscaping
• Close windows and doors
• Avoid electrical fixtures

Do Use Appropriate Detergents

• Choose cleaners designed for pressure washers
• Use the right cleaner for each surface
• Allow proper dwell time

The Don'ts of Pressure Washing

Don't Use Maximum Pressure on Everything

High pressure can:

• Splinter wood
• Crack siding
• Etch concrete
• Strip paint

Don't Hold the Nozzle Too Close

• Wood: No closer than 12 inches
• Siding: No closer than 12 inches
• Concrete: No closer than 6 inches

Don't Use a Zero-Degree Nozzle on Delicate Surfaces

The concentrated spray can:

• Cut through wood
• Damage paint
• Crack windows

Don't Pressure Wash These Items

• Old or damaged wood
• Painted surfaces with lead paint
• Electrical panels or meters
• HVAC units
• Windows (use low pressure only)

Don't Spray at Angles into Siding

Water can get behind siding, causing:

• Mold growth
• Insulation damage
• Structural issues
