Why Clean Your Siding in Snohomish County?

Maintaining the siding of our properties in Snohomish County is crucial for several reasons:

  • Preserving Property Value: Regular cleaning helps maintain our homes’ value and aesthetic appeal. A clean exterior is one of the first things potential buyers notice.
  • Preventing Damage: Due to our region’s wet climate, algae, mold, and mildew thrive. If not regularly washed away, these can cause lasting damage to siding materials.

In the following list, we outline the key benefits of keeping our siding clean:

  1. Enhanced Curb Appeal: We understand that a home’s appearance reflects on its owner. Clean siding ensures a positive impression on visitors and passersby.
  2. Extended Lifespan: By routinely removing harmful substances, we extend the lifespan of our siding, saving us from costly repairs or replacements.
  3. Health Considerations: Algae and mold are unsightly; they can pose health risks. Ensuring our siding is clean minimises these risks for us and our families.
  4. Local Climate Conditions: Snohomish County’s unique climate can accelerate the buildup of dirt and grime. Proper maintenance is vital to counteract this.

Proactive maintenance is the key. We focus on using gentle but effective cleaning methods to protect our siding and ensure that our homes remain beautiful and structurally sound amidst the challenges of the local climate.

Types of Siding

When considering siding for your Washington property, it’s essential to understand the various types available and their respective characteristics. Each siding material offers distinct benefits and maintenance requirements.


Vinyl siding is a popular choice due to its affordability and durability. Made from PVC, it is designed to withstand elements like rain, wind, and sunlight without fading or rotting. Cleaning vinyl siding typically involves a mild soap solution and a soft brush.


Wood siding offers a timeless aesthetic appeal and natural beauty. Commonly used types include cedar and redwood, naturally resistant to rot and pests. To maintain wood siding, regular staining or painting is necessary to protect it from moisture and UV rays.


Brick siding is known for its longevity and classic look. Made from fired clay, brick is non-combustible and requires minimal maintenance. Occasional cleaning with water and a mild detergent is typically all needed to keep brick siding in good condition.


Stucco siding provides a unique texture and is composed of cement, sand, water, and lime. It is highly customizable in terms of color and texture. To maintain stucco siding, periodic cleaning and sealing are recommended to prevent cracks and water infiltration.

Properly cleaning vinyl siding enhances the curb appeal of your Washington home and extends its lifetime. We’re outlining a tried-and-true process for effectively tackling dirt, mildew, and stains on your vinyl siding.

Gather Supplies

We’ll need a few essential items to start:

  • Warm water: Mix with the cleaning solution.
  • General-purpose cleaner: Dawn Dish Soap or Soft Scrub for the solution.
  • Bucket: To hold your cleaning mixture.
  • Large sponge or soft-bristle brush: For application of the solution.
  • Gloves: To protect our hands when handling the cleaning solution.
  • Safety glasses and sun hat (optional): For protection against prolonged sun exposure and splashes.

Prepare Cleaning Solution

We should follow these steps to create an effective cleaning mixture:

  1. Mix water with cleaner: Combine the warm water with a general-purpose cleaner at the ratio recommended on the cleaner’s label.
  2. Vinegar solution (optional): Mix approximately 30% water with 70% white vinegar for a more eco-friendly approach or to tackle mildew.

Note: Always read and adhere to the manufacturer’s instructions when mixing any cleaning solution.

Clean the Siding

Here’s how we’ll apply our cleaning solution:

  1. Apply from bottom to top: Scrub the siding gently with the mixture using the large sponge or brush, working our way up to prevent streaks.
  2. Scrub in sections: Tackle one section at a time to ensure thorough cleaning and easy management.
  3. Focus on overlap: Clean along the full length of each lap to remove build-up effectively.

Rinse the cleaned area before the solution dries to avoid leaving any residue.

Rinse and Dry

Lastly, we should perform the following:

  • Rinse carefully: After scrubbing, rinse each section with a hose, working from top to bottom.
  • Avoid water seepage: Direct the water stream to prevent water from getting behind the siding.
  • Let it dry: Allow the siding to air dry. We should not need to manually dry it unless for specific reasons, such as immediate painting.

How to Clean Wood Siding

To maintain the elegant look of our wood siding in Washington’s diverse climate, we focus on using effective cleaning methods that protect the wood’s integrity.

Choose the Right Solution

For general cleaning, a mixture of equal parts white vinegar and water is an eco-friendly choice. For tougher stains, diluting bleach with water (a 1:1 ratio) is beneficial. To prevent damage, test any solution on a small, inconspicuous area of your siding first.

  • General Cleaning: White vinegar and water (1:1)
  • Tough Stains: Bleach and water (1:1)

Scrub the Siding

Use a soft-bristle brush to apply the cleaning solution. Start from the top of our siding and work downward in sections to maintain consistency and avoid streaking. Apply gentle pressure to avoid scratching the wood.

  • Tool: Soft-bristle brush
  • Method: Top-to-bottom application

Remove Stubborn Stains

When facing stubborn grime or mold, we let the bleach solution sit for 10-20 minutes before scrubbing. This allows the solution to penetrate and loosen the buildup. Mold and mild stains require careful handling to avoid wood damage.

  • Waiting Time: 10-20 minutes
  • Target: Mold, mildew, and heavy stains

Rinse and Dry

After scrubbing, we thoroughly rinse the siding with a garden hose to remove any residue from the cleaning solutions. Rinsing well is important to prevent potential damage from the cleaners. Then, we allow the siding to air dry completely.

  • Rinse Tool: Garden hose
  • Drying: Air dry

How to Clean Brick and Stucco Siding

In this section, we’ll explain the best practices for cleaning brick and stucco siding to maintain the pristine condition of your Washington property.

Pressure Wash

We recommend starting the cleaning process with a gentle pressure wash. For brick siding:

  • Use a low-pressure nozzle to avoid damaging the mortar.
  • Hold the washer at a 30-degree angle to the wall.

When addressing stucco siding:

  • Attach a low pressure spray tip nozzle.
  • Avoid high pressure, which can erode stucco surfaces.

Use a Cleaning Solution

After pressure washing, apply a cleaning solution for deeper grime. For both brick and stucco:

  • Brick: Mix water with a small amount of dish soap. For stubborn stains, you can use a specialized brick cleaner.
  • Stucco: A solution of water and mild, non-acidic soap is adequate.

Apply the solution using a soft-bristle brush, scrubbing gently in a circular motion.

Remove Mold and Mildew

In Washington’s damp climate, mold and mildew are common on the siding. To remove these:

  • Prepare a solution of one part bleach to four parts water.
  • Apply it to affected areas, leaving it for 10 minutes on brick, and slightly less on stucco to prevent discoloration.
  • For stucco, a product like Wet & Forget Outdoor can also be effective, and used according to the manufacturer’s directions.

Rinse and Dry

The final step is to rinse thoroughly with clean water. Ensure the following:

  • Rinse from top to bottom to prevent streaks on the brick.
  • Use a gentle spray for stucco to avoid saturating and potentially damaging the material.

Allow the siding to air dry, avoiding direct sunlight which may cause uneven drying and water spots.

FAQ: Cleaning Various Types of Siding

It’s recommended to clean your siding at least once a year. However, in areas like Snohomish County, where the climate can be particularly harsh, you might need to clean it more frequently, especially if you notice buildup of dirt, mold, or mildew.

While pressure washers can be used on many types of siding, it’s essential to adjust the pressure accordingly. Vinyl, brick, and stucco can handle pressure washing, but for wood siding, a gentler approach with lower pressure is advisable to prevent damage. Always start with a lower pressure setting and increase it if necessary.

For most types of siding, a mixture of mild detergent and water works well. For vinyl siding, a solution of white vinegar and water is effective. Wood siding requires wood-safe cleaners, and for brick and stucco, masonry cleaners are ideal. Avoid using harsh chemicals that could damage the siding or harm the environment.

Regular cleaning is key to preventing mold and mildew. Ensure that your gutters are clean and functioning correctly to avoid water runoff that can lead to mold growth. Trimming back trees and shrubs around your home can also help reduce moisture buildup on your siding.

Hiring a professional like Triple Clean Power Washing ensures that your siding is cleaned thoroughly and safely. Professionals have the right equipment and expertise to handle various types of siding, preventing damage and ensuring effective cleaning. Additionally, it saves you time and effort, allowing you to focus on other important tasks
