Pressure Washing Siding: Top Tips for Maintaining Your Home’s Curb Appeal


Maintaining your home’s curb appeal isn’t just about aesthetics; it’s about preserving its value and ensuring longevity. One of the most effective ways to achieve this is through pressure washing. Let’s dive into the world of pressure washing sidings and discover the best practices.


Pressure Washing Home Sidings: An Overview

Pressure washing home sidings is a transformative maintenance technique that rejuvenates a home’s exterior, enhancing its curb appeal. By using controlled water pressure, it can effectively remove dirt, grime, mold, and mildew from various siding materials, including vinyl, wood, and aluminum. 

However, it’s crucial to understand the specific requirements of each material and use the appropriate pressure settings, techniques and cleaning solutions to ensure a safe and efficient cleaning process.

Preparing to Pressure Wash Your Siding

Proper preparation is the key to a successful pressure washing experience. Here’s a detailed breakdown of the steps to take before you begin:

  1. Cover Eaves, Vents, and Light Fixtures: These areas are often delicate and can be damaged by direct water pressure. Use waterproof covers or plastic sheeting to protect them. This not only prevents water damage but also keeps them free from any cleaning solutions you might use.
  2. Check Weather Conditions: The ideal day for pressure washing is calm and overcast. Bright, sunny days might cause your cleaning solution to evaporate too quickly, reducing its effectiveness. On the other hand, windy days can make it challenging to control the direction of the spray and might blow the cleaning solution off the surface before it has done its job.
  3. Clear the Area: Remove any obstacles around the siding, such as outdoor furniture, plant pots, and decorations. This ensures you have a clear space to work and prevents any items from getting damaged.
  4. Inspect the Siding: Before you start, do a quick inspection of your siding. Look for any signs of damage or areas that might need special attention. This will help you determine the right pressure settings and whether certain sections might need a gentler touch.
  5. Choose the Right Cleaning Solution: Depending on the material of your siding and the type of dirt or grime you’re dealing with, you’ll need to select an appropriate cleaning solution. Ensure it’s approved for pressure washer use.
  6. Test a Small Area: Before you begin the full task, test a small, inconspicuous area of your siding. This will help you gauge the effectiveness of your cleaning solution and ensure the pressure setting is appropriate.

By taking these preparatory steps, you set yourself up for a smooth and effective pressure washing session, ensuring the longevity and beauty of your home’s exterior.


Essential Equipment for Pressure Washing

Pressure Washing Equipment

Equipment to Use

  • Pressure Washer: Gas-powered pressure washers are more potent and ideal for stubborn dirt.
  • Extension Wand & Telescoping Wand Tool: These tools help you reach high areas without a ladder.
  • Pressure Washer Detergent Injector: This allows you to apply soap or detergent effectively.
  • Rotating or Utility Brush: For scrubbing stubborn areas.
  • Foaming Brush: Helps in applying detergent evenly.


Understanding PSI for Cleaning Siding

PSI, or Pounds per Square Inch, is a measure of the pressure exerted by the water coming out of the pressure washer. The correct PSI is crucial when pressure washing sidings to ensure effective cleaning without causing damage. Different materials have varying resilience to pressure, so it’s essential to adjust the PSI accordingly.

Different PSI Settings for Various Materials

Brick, Vinyl, Steel, Stone (1,300 to 1,500 PSI):

  1. Brick (PSI: 1,400 to 1,500 PSI)

Being a hard material, brick can withstand higher pressures. However, old or deteriorating bricks might be more susceptible to damage.

  1. Vinyl (PSI: 1,300 to 1,400 PSI) 

While durable, vinyl can be dented or damaged with excessive pressure. The recommended PSI ensures effective cleaning without causing harm.

  1. Steel (PSI: 1,400 to 1,500 PSI)

Steel sidings are robust and can handle higher pressures, but it’s essential to ensure even pressure to prevent denting.

  1. Stone (PSI: 1,300 to 1,500 PSI)

Natural stone is hardy, but its porous nature means it can trap dirt. The right PSI ensures deep cleaning without eroding the stone.

Stucco, Aluminum and Painted Soft-Grain Wood (1,200 to 1,400 PSI):

  1. Stucco (1,200 to 1,300 PSI) 

A delicate material, stucco can be easily damaged with high pressure. The recommended PSI ensures the removal of dirt without causing cracks or chipping.

  1. Aluminum (1,250 to 1,350 PSI)

While aluminum is a durable material, it can dent if the pressure is too high. The given PSI range ensures effective cleaning without causing deformities.

  1. Painted Soft-Grain Wood (1,200 to 1,400 PSI) 

Softwoods like pine, larch, and fir can be damaged or have their paint stripped off with high pressure. The suggested PSI ensures the wood is cleaned without causing harm or stripping paint.

Pro-Tip: Always start with a low-pressure spray, especially if you’re unfamiliar with the material you’re cleaning. It’s easier to adjust upwards as needed than to repair damage caused by excessive pressure. Remember, the goal is effective cleaning without compromising the integrity of the siding material.


Siding Cleaning Solutions for Pressure Washers

The Role of Bleach in Pressure Washing

Though undiluted bleach has its corrosive tendencies, when diluted, it becomes a potent ally in combating mold and mildew. However, it’s paramount to use bleach solutions that are sanctioned for pressure washer application.

The Importance of Detergents in Pressure Washing

Detergents or soaps are not just additives; they play a pivotal role in disintegrating contaminants, amplifying the efficiency of the cleaning process. It’s crucial to opt for solutions tailor-made for pressure washers.


Tips for Pressure Washing Specific Siding Types

Pressure Washing Brick Siding

Pressure Washing Brick Siding

Brick, with its rugged texture and porous nature, can accumulate dirt and grime over time. Here’s how to effectively clean it:

  1. Wet the Surface with a Low-Pressure Spray: This initial step helps to soften the dirt and prepares the brick for cleaning.
  2. Apply the Detergent Solution, Starting from the Bottom: Starting from the bottom prevents streaks caused by detergent runoff. Let the solution sit for a few minutes to break down the dirt.
  3. Use a Rotating Brush for Stubborn Dirt: Brick can have deep-set stains. A rotating brush can help dislodge this stubborn dirt without damaging the brick.
  4. Rinse with Clean Water: Ensure all detergent and loosened dirt are washed away, leaving the brick looking refreshed.

Pressure Washing Vinyl Siding

Pressure Washing Vinyl Siding

Vinyl is a popular siding choice due to its durability and low maintenance. Here’s how to keep it looking its best:

  1. Use a Foaming Brush to Apply the Detergent: A foaming brush ensures even application and helps the detergent penetrate dirt and grime.
  2. Clean from Top to Bottom to Prevent Streaks: This method ensures that any runoff is cleaned as you work your way down, preventing unsightly streaks.
  3. Rinse Thoroughly: Make sure all detergent is rinsed off to prevent residue buildup.

Pressure Washing Wood Siding

Pressure Washing Wood Siding

Wood is a delicate material that requires a gentle touch:

  1. Use a Gentle Spray to Avoid Damaging the Wood: High pressure can strip the paint or damage the wood grain. Always start with a gentle setting.
  2. Apply Detergent and Scrub Gently: Use a soft brush to apply the detergent and scrub. This ensures the wood isn’t scratched or damaged.
  3. Rinse with Low Pressure: Ensure all detergent is rinsed off without blasting the wood with high pressure.

Pressure Washing Aluminum Siding

Pressure Washing Aluminum Siding

Aluminum is sturdy but can dent if not handled correctly:

  1. Pre-Treat Any Mildew, Grime, and Stains: Use a cleaning solution to treat these areas before the main wash. This ensures a more thorough clean.
  2. Wash Using a Medium Pressure Setting: This pressure setting is strong enough to clean but won’t dent the aluminum.
  3. Rinse from Top to Bottom: Like with vinyl, this method ensures a streak-free finish.


Benefits of Pressure Washing House Siding

  1. Aesthetic Appeal: Removes dirt, grime, and stains, enhancing your home’s beauty.
  2. Health Benefits: Eliminates harmful substances like mildew, bacteria, and fungi.
  3. Structural Benefits: Prevents rot and decay, extending the lifespan of your siding.
  4. Value Addition: A clean home can significantly boost property value.

What Not To Do When Pressure Washing Siding

  1. Avoid high-pressure settings on soft materials.
  2. Never use corrosive cleaning solutions.
  3. Don’t pressure wash in extreme weather conditions.

Pressure Washing Siding Cost

The cost varies based on the size of your home, the material of the siding, and whether you opt for DIY or professional services. On average, professional services range from $100 to $300 for a single-story home.
