Pressure washing is an effective way to clean the exterior of your house, removing dirt, grime, mold, and mildew. However, before you start, it’s important to properly prepare your home to ensure the process is safe and effective. Here’s a comprehensive guide on how to prepare your house for pressure washing.

Inspect Your Home’s Exterior

Before you begin pressure washing, thoroughly inspect the exterior of your home. Look for any damage or areas that might need special attention.

Check for Cracks and Holes

Examine the siding, windows, doors, and foundation for any cracks, holes, or loose materials. Pressure washing can worsen existing damage, so it’s essential to repair these issues beforehand. Fill in any cracks or holes with caulk or appropriate sealant.

Protect Landscaping

Identify Delicate Areas

Note areas that might be sensitive to high-pressure water, such as older wood, vinyl siding, or painted surfaces that might peel. Plan to use a lower pressure setting or avoid these areas altogether to prevent damage.

Clear the Surrounding Area

Remove any obstacles that could interfere with the pressure washing process or be damaged by the water.

Move Outdoor Furniture and Decorations

Move patio furniture, potted plants, and garden decorations away from the house. This ensures they don’t get in the way and prevents them from getting damaged or dirty during the cleaning process.

Cover nearby plants, flowers, and shrubs with tarps or plastic sheeting to shield them from the force of the water and any cleaning solutions you might use. Be sure to water your plants before covering them to help them withstand any chemical exposure.

Clear the Ground

Remove any debris, such as sticks, leaves, or toys, from around the house. This helps prevent tripping hazards and ensures a thorough cleaning.

Prepare the Exterior Surfaces

Proper preparation of the surfaces you’ll be washing is crucial for effective cleaning.

Close Windows and Doors

Ensure all windows and doors are securely closed to prevent water from getting inside your home. Check the seals around windows and doors for any gaps and repair them as needed.

Cover Electrical Outlets and Fixtures

Cover exterior electrical outlets, light fixtures, and other electrical components with waterproof tape or plastic to prevent water damage. Turn off the power to exterior outlets at the breaker box as an extra precaution.

Remove Screens and Shutters

If possible, remove window screens and shutters to allow for better access to the surfaces behind them. This ensures a more thorough cleaning and prevents these items from being damaged.

Select the Right Cleaning Solutions

Choosing the appropriate cleaning solutions is essential for effective and safe pressure washing.

Choose Biodegradable Detergents

Select biodegradable and environmentally friendly detergents to avoid harming your landscaping and the environment. Make sure the detergent is suitable for the type of surface you’ll be cleaning, whether it’s wood, vinyl, brick, or stucco.

Test the Detergent

Before applying the detergent to the entire surface, test it on a small, inconspicuous area to ensure it doesn’t cause discoloration or damage.

Set Up the Pressure Washer

Proper setup of your pressure washer is crucial for effective and safe operation.

Select the Right Nozzle

Pressure washers come with various nozzles that provide different spray patterns and pressures. Choose a nozzle appropriate for the surface you’re cleaning. A 25-degree nozzle is typically a good starting point for general cleaning, while a 15-degree nozzle is better for tougher stains.

Adjust the Pressure

Start with a lower pressure setting and gradually increase it as needed. Using too high a pressure can damage surfaces, while too low a pressure may not effectively clean.

Fill the Detergent Tank

If your pressure washer has a detergent tank, fill it with the appropriate cleaning solution. Follow the manufacturer’s instructions for the correct dilution ratio.

Safety Precautions

Pressure washing involves high-pressure water, which can be dangerous if not handled properly.

Wear Protective Gear

Wear safety goggles, gloves, and sturdy footwear to protect yourself from debris and the force of the water. Long sleeves and pants can also help protect your skin from potential chemical splashes.

Be Aware of Your Surroundings

Pay attention to your surroundings and keep children and pets away from the area you’re cleaning. The high-pressure water can cause serious injuries.

Use Caution with Ladders

If you need to use a ladder to reach higher areas, exercise caution. The force of the pressure washer can make it difficult to maintain your balance. Consider using an extension wand instead of a ladder when possible.

Begin Pressure Washing

With all the preparations complete, you’re ready to start pressure washing.

Start from the Bottom

Begin washing from the bottom of the house and work your way up. This prevents streaks and ensures that dirty water doesn’t run down onto clean areas.

Maintain a Safe Distance

Keep the pressure washer nozzle at least 6 inches to 12 inches away from the surface you’re cleaning. This helps prevent damage to the surface and ensures effective cleaning.

Use a Consistent Motion

Move the pressure washer nozzle in a consistent, sweeping motion. Avoid staying in one spot for too long, as this can cause uneven cleaning or damage.

Post-Washing Steps

Once you’ve finished pressure washing, there are a few additional steps to complete the process.

Rinse Thoroughly

Rinse the entire surface with clean water to remove any remaining detergent. This prevents residue from drying on the surface and potentially causing damage.

Inspect for Missed Areas

After rinsing, inspect the exterior for any missed spots or areas that need additional cleaning. Re-wash these areas as necessary.

Clean Up

Turn off the pressure washer and disconnect it from the water supply. Drain any remaining detergent from the tank and clean the nozzles. Store the pressure washer and accessories in a safe, dry place.

Preparing your house for pressure washing involves careful planning and attention to detail. By inspecting your home, clearing the surrounding area, preparing the surfaces, selecting the right cleaning solutions, setting up the pressure washer correctly, and taking necessary safety precautions, you can ensure a thorough and safe cleaning process. Proper preparation not only protects your home from potential damage but also maximizes the effectiveness of pressure washing, leaving your home looking clean and well-maintained.
