When it comes to maintaining the exterior of your house, pressure washing can be a highly effective and efficient method. However, if you have a tall house, reaching those high areas can be a challenge. Don’t worry though, with the right equipment and techniques, you can successfully pressure wash even the tallest of houses.

First and foremost, safety should be your top priority. Before you start, make sure you have a sturdy ladder that can reach the desired height. It’s also essential to wear protective gear such as safety goggles and non-slip shoes. Taking these precautions will ensure that you can work comfortably and reduce the risk of accidents.

Next, you’ll need to choose the appropriate pressure washer for the job. Opt for a pressure washer with a long wand and hose extension to reach the high areas of your house. The pressure washer should have enough power to effectively remove dirt and grime without damaging the surfaces. Additionally, consider using a cleaning solution specifically designed for pressure washing to enhance the cleaning process.

Once you have your equipment ready, start by thoroughly inspecting the exterior of your house. Identify any loose or damaged siding, as pressure washing can exacerbate these issues. Take the time to make any necessary repairs before proceeding with the pressure washing. This will prevent further damage and ensure a more effective cleaning.

When pressure washing a tall house, it’s crucial to work in sections. Begin from the bottom and work your way up, using long, sweeping motions. This technique allows you to maintain better control over the spray and ensures a thorough clean. Remember to keep the nozzle at an angle, pointing down, to prevent water from seeping behind the siding.

By following these steps, you can pressure wash your tall house effectively and efficiently, leaving it looking clean and refreshed.

Prepare Your Equipment

Before starting to pressure wash your tall house, it’s important to gather all the necessary equipment. Here’s a step-by-step guide to help you prepare:

  1. Pressure washer: Make sure you have a pressure washer with enough power to reach the height of your house. Check the manufacturer’s recommendations for the appropriate psi (pounds per square inch) and GPM (gallons per minute) for your specific model.
  2. Nozzle extension wand: Since you’re pressure washing a tall house, you’ll likely need a nozzle extension wand to reach the higher areas. This will help you maintain a safe distance while still effectively cleaning.
  3. Safety gear: Protect yourself by wearing the appropriate safety gear, including safety glasses or goggles, ear protection, and non-slip shoes. Additionally, consider wearing a hat to protect yourself from any falling debris.
  4. Detergent: Depending on the condition of your house’s exterior, you may want to use a detergent specifically designed for pressure washing. This can help remove tough stains, mold, and mildew.
  5. Water source: Ensure that you have a reliable water source nearby. If you’re using a pressure washer that requires a water hose, make sure it’s long enough to reach all areas of your house.
  6. Protective coverings: If there are any delicate plants or outdoor furniture near your house, consider covering them with tarps or plastic sheeting to protect them from any overspray or debris.
  7. Test area: Before starting to pressure wash the entire house, it’s a good idea to test a small, inconspicuous area. This will help ensure that you’re using the correct pressure and nozzle settings without causing any damage.

By properly preparing your equipment, you’ll be ready to tackle the task of pressure washing your tall house effectively and efficiently.

Before you begin pressure washing your tall house, it’s important to properly set up your pressure washer. Follow these steps to ensure everything is in order:

1. Choose the Right Nozzle

Start by selecting the appropriate nozzle for the job. Different nozzles have different spray patterns and pressures, so choose one that suits your purposes. For general cleaning, a 25-degree nozzle is often a good choice.

Next, connect your pressure washer to a suitable water source. This can be a garden hose connected to an outdoor spigot or a dedicated water supply. Make sure the water supply is turned on and flowing freely before proceeding.

3. Attach the Hose and Wand

Once you have connected the water source, attach the high-pressure hose to the pressure washer. Ensure that it is securely fastened. Then, attach the wand to the end of the hose, making sure it is also tightly secured.

4. Turn on the Pressure Washer

Before starting the pressure washer, check the oil level and fuel level (if applicable) to ensure they are sufficient. Then, turn on the pressure washer according to the manufacturer’s instructions. Allow it to run for a few minutes to warm up.

5. Test the Pressure

With the pressure washer running, squeeze the trigger on the wand to release water. Check the pressure by aiming the wand at a safe, open area. Be cautious of the force and adjust the pressure if needed.
