How do you pressure wash a house?

At Softwash Australia, we understand the importance of maintaining the beauty and integrity of your home’s exterior. Pressure washing is an efficient way to remove dirt, mould, and grime, ensuring your property stays in top condition. Whether you’re preparing for a paint job or simply freshening up your home’s appearance, proper pressure washing can make a significant difference.

Preparation for pressure washing your house

Before starting, it's essential to prepare your home and surrounding areas. Begin by covering plants, shrubs, and outdoor furniture with plastic sheeting or tarps to protect them from water and cleaning solutions. Close all windows and doors securely, and cover any exposed electrical outlets to prevent water from getting inside. Inspect the exterior for any loose paint, cracks, or damage, and make necessary repairs to avoid water intrusion during the wash​​.

Choosing the Right Equipment and Materials

Selecting the appropriate pressure washer is crucial. For most homes, a pressure washer with a rating between 2,000 to 3,000 PSI is sufficient. Use a 25- or 40-degree nozzle for a wide spray that is less likely to damage your siding. You’ll also need a cleaning solution specifically designed for pressure washers, which often includes mildewcide to eliminate mould and mildew​​.

Steps for Pressure Washing

  1. Pre-soak and Scrub: Start by applying a cleaning solution to your house using a garden sprayer. Work in sections, and scrub the siding with a soft brush from bottom to top. This ensures that you’re removing dirt rather than spreading it around​​.
  2. Pressure Washing: After scrubbing, it’s time to pressure wash. Begin at the top of your house and work your way down, using a consistent, side-to-side motion. Maintain a distance of about 3 feet from the wall to avoid damaging the siding. Always keep the nozzle at a 45-degree angle to prevent water from getting underneath the siding​​.
  3. Rinse Thoroughly: Once you’ve applied the cleaning solution and given it time to work (typically about 10 minutes), rinse the house from top to bottom using plain water. This step ensures all cleaning agents and dirt are completely removed, leaving a clean surface​.

Post-Washing Care

After pressure washing, allow your house to dry completely, which can take up to 48 hours. This is particularly important if you plan to repaint or apply a sealant. Finally, remove all protective coverings and clean up any remaining debris​.

Safety Tips

Always prioritise safety when pressure washing. Wear protective gear, including goggles and sturdy clothing, to protect yourself from flying debris. Avoid using ladders; instead, use an extension wand if you need to reach higher areas. Additionally, be mindful of any electrical hazards and avoid spraying directly into vents or electrical outlets​.

By following these steps, you can effectively pressure wash your house, enhancing its curb appeal and longevity. Regular maintenance, like pressure washing every two years, helps keep your home in top condition

How Long Should It Take to Pressure Wash a House?

The time it takes to pressure wash a house depends on several factors, including the size of the house, the extent of dirt buildup, and the type of siding. Generally, a standard one-story home can take anywhere from 30 minutes to two hours to clean thoroughly. Larger or multi-story homes may require additional time, especially if you’re working carefully to avoid damage to the siding. It's important to allow sufficient time for pre-soaking, scrubbing, and rinsing each section of the house to ensure a comprehensive clean
