Exterior building pressure washing involves using a high-powered water spray to clean surfaces like brick, concrete, wood, and vinyl siding.

Benefits of Pressure Washing Your Building

Pressure washing offers numerous benefits, including:

  • Preventive Maintenance: Regular cleaning prevents the buildup of harmful substances that can cause structural damage.
  • Healthier Environment: Removing mold and mildew improves air quality and reduces health risks.
  • Increased Property Value: A well-maintained exterior can boost property value and appeal to potential buyers or tenants.

Choosing the Right Pressure Washer

Selecting the right pressure washer depends on several factors:

  • Electric vs. Gas: Electric washers are quieter and easier to maintain, suitable for small to medium tasks. Gas-powered washers offer more power for larger jobs. When servicing a commercial high rise we only use industrial machines for top results.
  • PSI and GPM: Pounds per square inch (PSI) and gallons per minute (GPM) determine the washer’s cleaning power. Higher PSI and GPM are ideal for tougher jobs. We only use 300PSI max on any building to protect the structure of the establishment orifices.

Safety Gear and Precautions

Pressure washing can be dangerous if not done correctly. Always use safety gear, including:

  • Safety Goggles: Protect your eyes from debris and splashes.
  • Gloves: Prevent hand injuries from high-pressure water.
  • Non-slip Shoes: Ensure stable footing on wet surfaces specially when working on tile roofs or boom lifts.
  • Hearing Protection: Gas-powered washers can be loud.

Best Practices for Pressure Washing

To achieve the best results, follow these best practices:

  • Test an Area First: Always test a small, inconspicuous area to ensure the pressure setting and technique won’t damage the surface.
  • Use Appropriate Nozzles: Choose the right nozzle for the task to avoid surface damage.
  • Maintain Consistent Distance: Keep the spray nozzle at a consistent distance from the surface, typically 12-18 inches.

Preparing Your Building for Pressure Washing

Preparation is key to a successful pressure washing job. Steps include:

  • Clear the Area: Remove furniture, vehicles, and other obstacles.
  • Cover Plants and Fixtures: Protect plants, light fixtures, and electrical outlets with plastic sheeting.
  • Repair Damages: Fix any cracks or loose materials to prevent water infiltration.
