Power washing is an effective method for cleaning the exterior of a two-story house. Whether you’re dealing with dirt, grime, mold, or mildew, a power washer can make the job easier. In this article, we will go over everything you need to know to power wash a two-story house, step by step. By the end of this guide, you’ll be equipped with the knowledge to get your house looking fresh and clean.
Understanding Power Washing
Power washing involves using a high-pressure stream of water to clean surfaces. It’s different from regular hose washing because the water is propelled at a higher pressure, making it much more effective at removing tough dirt, algae, and other unwanted buildup. The pressure is measured in PSI (pounds per square inch), and the higher the PSI, the more powerful the washer.
There are two main types of washers:
1. Electric Power Washers
Electric power washers are ideal for smaller jobs and are easier to use. They are quieter and lighter, but their pressure levels tend to be lower, which means they are better suited for light cleaning tasks.
2. Gas Power Washers
Gas-powered washers are more powerful and are better suited for heavy-duty tasks like power washing a two-story house. They offer higher PSI levels and are ideal for larger homes or surfaces that need a deep clean.
Preparing for the Power Wash
Before you start, make sure you have all the necessary tools and equipment. Here’s what you will need:
1. Power Washer
As mentioned earlier, a gas-powered washer is ideal for this type of job. Make sure the washer is in good working condition, and check that it has the appropriate PSI for cleaning exterior surfaces.
2. Nozzles
Power washers come with different nozzle attachments. The size of the nozzle will determine the pressure of the water. For general cleaning, use a 25-degree or 40-degree nozzle. If you’re dealing with stubborn grime or mold, you may need a more powerful nozzle.
3. Cleaning Solutions
While water alone can clean a lot of dirt, sometimes you need a cleaning solution. If you’re washing a particularly dirty or moldy area, you might want to use a specialized detergent or mold cleaner. Make sure the detergent is safe for the surface you’re cleaning.
4. Ladders or Scaffolding
Since you’re power washing a two-story house, you will need to reach higher areas. A sturdy ladder or scaffolding will be essential to ensure safety while working at heights.
5. Protective Gear
Power washing involves high-pressure water that can be harmful if it hits your skin. Wear protective gear like goggles, gloves, and long-sleeved clothing to avoid injury.
Steps to Power Wash a Two-Story House
Now that you’re prepared, let’s dive into the actual process of power washing your two-story house.
1. Inspect the House Exterior
Before you begin, take some time to inspect the exterior of your house. Look for areas that are particularly dirty, moldy, or covered in algae. Also, check for any damage to the walls, windows, or siding that may require extra attention. It’s important to ensure that your house is in good shape before using a high-pressure washer.
2. Set Up the Power Washer
Place the power washer on a flat surface, and make sure the hose is securely attached. For gas-powered washers, ensure that the fuel tank is full. Connect the water supply and check for any leaks in the hose or fittings.
Adjust the pressure setting on your washer based on the surface you’re cleaning. For most house exteriors, a pressure setting between 2,000 and 3,000 PSI is sufficient. Start at a lower setting if you’re unsure to avoid damaging the siding or paint.
3. Start Washing from the Top Down
When you’re ready to begin power washing, always start at the top of the house and work your way down. This ensures that dirt and grime don’t fall onto areas you’ve already cleaned.
Begin by spraying the roof or upper sections of the house. Hold the nozzle about 3 feet from the surface and maintain a steady motion. Don’t focus the water on one spot for too long, as this can damage the surface.
As you work your way down, rinse off any cleaning solutions or detergent that you’ve used. Be mindful of the water pressure near windows and doors, as it can cause damage if the pressure is too high.
4. Power Wash the Siding
Once the upper areas are clean, move on to the siding of the house. Start from the top and move downward. For vinyl siding, be careful not to get too close, as the high pressure can strip away the finish. Keep the nozzle at least 12 inches away from the surface for safe cleaning.
For brick or stone, you can use higher pressure but still start from the top and work your way down. Keep in mind that some types of siding may require special care. Wood siding, for example, is more delicate and should be power washed with lower pressure to avoid damage.
5. Clean the Windows and Doors
Windows and doors are delicate, so you should approach them with caution. Use a 40-degree nozzle to gently clean the windows, ensuring the pressure is not too high. Work from the top of the window frame down to avoid streaks.
For doors, avoid focusing the water on locks or any mechanical parts. If necessary, wipe the doors down by hand after power washing to ensure they are thoroughly cleaned.
6. Address Stubborn Areas
After the general washing, take a closer look at areas with heavy mold, mildew, or stains. For stubborn spots, apply a cleaner designed for those specific stains and let it sit for a few minutes before using the power washer again. Be sure to follow the manufacturer’s instructions for the cleaning products to avoid damage.
For areas with heavy mold growth, you may need to repeat the washing process or scrub the surface lightly with a brush before power washing again.
7. Check for Remaining Dirt
Once you’ve cleaned all surfaces, take a step back and inspect the house. If there are any remaining spots or areas that didn’t get cleaned properly, go over them again. Ensure that you’ve cleaned the foundation, gutters, and other low areas that may have been missed in the initial wash.
8. Let the House Dry
After washing, allow the house to dry completely. Depending on the weather, this can take several hours. If you’ve used any cleaning solutions or detergents, it’s important to rinse them off thoroughly before they dry on the surface.
9. Clean Up and Store Equipment
Once you’ve finished, it’s time to clean up. Drain the water from the power washer and store it in a safe place. Make sure to clean the nozzles and any accessories you used. Proper maintenance of your equipment will ensure it lasts longer and stays in good working condition.
Tips for Safe and Effective Power Washing
Test Pressure on a Small Area First: Before you start on large surfaces, test the pressure on a small, inconspicuous area of the house to ensure the water pressure is safe for the material.
Avoid Over-Wetting: Don’t oversaturate the surfaces. Over-wetting can cause water damage or lead to mold growth in certain areas.
Work in Sections: Break the house into manageable sections. This will help you stay organized and avoid re-washing areas.
Safety First: Always prioritize safety. If you’re working at height, use proper ladders or scaffolding, and never work alone.
Conclusion
Power washing a two-story house can seem like a big task, but with the right tools, techniques, and safety measures, you can achieve excellent results. By following the steps outlined in this guide, you’ll be able to clean your home’s exterior and restore its appearance to like-new condition.
Always remember to use the right pressure for each surface, take your time, and inspect the house for any signs of damage before starting. With patience and care, power washing can be a rewarding and efficient way to keep your home looking fresh and clean for years to come.
