Frequently Asked Questions About Pressure Washing

Can pressure washing remove mold and mildew?

Yes, pressure washing can effectively remove mold and mildew from various surfaces, but the appropriate cleaning method depends on the surface type and severity of the growth:

• Pressure Washing: For hard surfaces like concrete, brick, or decks, pressure washing can effectively remove mold and mildew. Use a cleaning solution containing bleach or mildewcide for optimal results.
• Soft Washing: For delicate surfaces like roofs or siding, soft washing is the preferred method for mold and mildew removal. Soft washing uses low-pressure water and specialized cleaning solutions to gently remove mold and mildew without damaging the surface.
• Prevention: After cleaning, take steps to prevent future mold and mildew growth by addressing moisture issues, such as fixing leaks, improving ventilation, and trimming vegetation that creates shade and traps moisture.

If you have extensive or persistent mold and mildew problems, consult with a professional pressure washing company or a mold remediation specialist.

Is it better to pressure wash or paint my house?

The decision of whether to pressure wash or paint your house depends on your goals and the condition of your siding:

• Pressure Washing: If your siding is in good condition but dirty or stained, pressure washing can effectively restore its appearance without the need for painting.
• Painting: If your siding is faded, chipped, peeling, or damaged, pressure washing alone may not be sufficient. Painting provides a fresh coat of protection and a new look.
• Pressure Washing Before Painting: Pressure washing is an essential step before painting, as it removes dirt, grime, and loose paint, creating a clean surface for the new paint to adhere to.

Assess the condition of your siding and your desired outcome to determine whether pressure washing, painting, or a combination of both is the best approach.

What are the different types of pressure washer nozzles?

Pressure washer nozzles come in various spray patterns and angles, each designed for specific cleaning tasks:

• 0-degree Nozzle: Produces a highly concentrated, powerful jet of water for removing stubborn stains or stripping paint. Use with caution as it can damage surfaces easily.
• 15-degree Nozzle: A versatile nozzle for cleaning concrete, brick, and other hard surfaces. Provides a good balance of pressure and coverage.
• 25-degree Nozzle: A wider spray pattern for cleaning delicate surfaces like siding or fences.
• 40-degree Nozzle: A very wide spray pattern, ideal for rinsing or applying cleaning solutions.
• Soap Nozzle: A low-pressure nozzle designed specifically for applying cleaning solutions.
• Rotary Nozzle: Also known as a turbo nozzle, it produces a rotating, high-impact spray for tackling tough stains and grime.

Choose the appropriate nozzle based on the cleaning task and the type of surface being cleaned. Consult the pressure washer manual or a professional pressure washer for guidance.

What are some common pressure washing mistakes to avoid?

Pressure washing, when done improperly, can lead to damage or unsatisfactory results. Here are some common mistakes to avoid:

• Using Excessive Pressure: High-pressure water spray can damage delicate surfaces like wood siding or painted surfaces.
• Using the Wrong Nozzle: Different nozzles produce different spray patterns and pressure levels. Using the wrong nozzle can cause streaks, uneven cleaning, or damage.
• Holding the Nozzle Too Close to the Surface: Holding the nozzle too close can etch or damage the surface. Maintain a safe distance as recommended by the pressure washer manufacturer.
• Skipping Pre-Treatment: For stubborn stains or mold growth, pre-treating the surface with a cleaning solution can enhance cleaning effectiveness.
• Not Protecting Plants and Landscaping: Pressure washing chemicals and debris can harm plants and landscaping. Cover or shield sensitive areas before pressure washing.

If you're unsure about pressure washing techniques or the appropriate pressure levels for your surfaces, consult with a professional pressure washing company.
