How to Pressure Wash Your Siding Like a Pro

Are you looking to give your siding a fresh new look, but don’t know where to start? Pressure washing can definitely be a daunting task, however it doesn’t have to be. With the right technique and tools, you too can pressure wash your siding like a pro! In this blog post, we will go over all of the necessary steps for pressure washing your siding efficiently and safely without damaging it. Let’s get started!

What You Need for Pressure Washing Your Siding 

To pressure wash your siding like a pro, you’ll need the following items:

  • Pressure Washer: A gas or electric pressure washer capable of delivering at least 1300 to 1600 PSI (pounds per square inch).
  • Pressure Washer Detergent: A specially formulated detergent designed for use with pressure washers. Make sure it’s safe for your type of siding.
  • Pressure Washer Nozzles: A selection of nozzles for different types of cleaning tasks. A 25-degree nozzle is commonly used for cleaning siding.
  • Safety Gear: Safety glasses to protect your eyes from flying debris, rubber gloves, and non-slip shoes.
  • Extension Wand: This tool helps you reach high places without the need for a ladder.
  • Brush: A soft-bristle brush for cleaning stubborn spots manually.

By gathering these tools in advance, you can ensure a smooth and efficient pressure washing process.

Prep Work Before You Start Pressure Washing 

Before you start pressure washing, it’s important to adequately prepare the area and protect your home. Here’s what you need to do:

  1. Inspect your siding: Look for any signs of damage, loose panels or areas that need repair. Pressure washing damaged areas can lead to water intrusion into your home.
  2. Cover windows and doors: Use plastic sheeting and painter’s tape to protect windows, doors, and other areas not suitable for pressure washing.
  3. Remove obstacles: Clear the area around your home of any obstacles such as furniture, grills, or potted plants.
  4. Wet plants and shrubs: Wet down any plants or shrubs near your home’s siding to help protect them from the detergent.
  5. Turn off power to outdoor electrical outlets: Ensure all external power sources, lights, and outlets are switched off to prevent potential electric shock.

Remember, the key to a successful and safe pressure washing experience is preparation. By undertaking these steps, you can ensure that your home is ready for a thorough clean.

Step-by-step Guide on How to Pressure Wash Your Siding 

Let’s delve into the step-by-step process to pressure wash your siding:

  1. Mix the Detergent: Follow your detergent’s instructions and mix it with water in your pressure washer’s detergent reservoir. 
  2. Attach the 25-degree Nozzle: After ensuring the pressure washer is turned off and the water supply is connected, attach the 25-degree nozzle to your pressure washer wand. 
  3. Apply the Detergent: Start at the bottom of your siding and work your way up, applying the detergent in smooth, overlapping strokes. Let the detergent sit for about 10 minutes, but do not let it dry on your siding.
  4. Scrub Stubborn Spots: Use a soft-bristle brush to manually scrub any stubborn spots that didn’t come clean with the detergent application.
  5. Rinse the Siding: Swap out your 25-degree nozzle for a 40-degree one to rinse your siding. Rinse from the top down to avoid streaks, making sure to remove all the detergent.
  6. Let it Dry: Allow your siding to dry completely. This may take a few hours depending on your local climate and the material of your siding.

By meticulously following these steps, you can effectively and safely pressure wash your siding, making it look as good as new. Remember to always wear your safety gear and to keep the pressure washer’s wand at a safe distance from your body and the siding to prevent potential damage.

Tips and Tricks for Pressure Washing Your Siding Like a Pro 

To elevate your pressure washing game, consider these pro-tips:

  1. Maintain a Consistent Distance: Keep the nozzle at a consistent distance from the siding, usually between 10 to 16 inches, to avoid causing damage.
  2. Opt for a Sweeping Motion: Move the pressure washer wand in a sweeping motion, either horizontally or vertically, to avoid leaving streak marks.
  3. Don’t Rush the Process: It’s crucial to be patient. Rushing might leave detergent residue or cause unwanted damage to your siding.
  4. Be Mindful of the Weather: Ideally, choose a day with moderate temperatures and overcast skies. Direct sunlight can cause the detergent to dry too quickly on the siding.
  5. Schedule Regular Pressure Washes: Regular maintenance can help prolong the life of your siding. Depending on where you live and your local climate, pressure washing your siding once or twice a year can help maintain its appearance.

Remember, the goal of pressure washing home siding is not only to clean it, but also to preserve its integrity for years to come.

Troubleshooting Common Problems When Pressure Washing Your Siding 

Despite your best efforts, you might encounter a few challenges during the pressure washing process. Here are some common problems and their respective solutions:

  1. Pressure Washer Not Starting: Check your power source, the water supply, and the engine oil level. If the pressure washer still doesn’t start, it might need a professional inspection.
  2. Insufficient Pressure: This could be due to a blockage in the nozzle or insufficient water supply. Clean the nozzle and ensure that the water source is delivering the necessary flow.
  3. Streaks on the Siding: This is often caused by uneven pressure application. Maintain a consistent distance and use a steady, overlapping sweeping motion when applying and rinsing the detergent.
  4. Siding Damage: If you notice any damage, it’s likely that the pressure setting is too high or the nozzle is too close to the siding. Adjust the pressure and maintain a safe distance to protect your siding.
  5. Detergent Not Dispensing: This could be due to a clogged detergent intake or an incorrect nozzle. Clean the detergent intake system and use a soap-specific nozzle.

Should problems persist after following these troubleshooting tips, consider contacting a professional to avoid further damage. Remember, it’s important to promptly address issues to maintain the effectiveness and safety of your pressure washing process.
