How to Pressure Wash Your Home Like a Pro (Step-by-Step Guide)

Pressure washing is an effective and efficient way to clean the exterior of your home, removing dirt, grime, mold, and mildew that accumulate over time.

Whether you're preparing your home for a fresh coat of paint or simply want to enhance its curb appeal, pressure washing can make a significant difference.

However, doing it wrong can cause damage to your home's exterior surfaces. In this guide, we’ll walk you through how to pressure wash your home like a pro, covering everything from selecting the right equipment to mastering the technique.

Why Pressure Washing is Important

Regularly pressure washing your home not only improves its appearance but also protects it from potential damage caused by buildup of harmful substances.

Mold, mildew, and algae can deteriorate your siding, deck, and other surfaces, leading to costly repairs. By pressure washing, you can extend the life of these surfaces and maintain the value of your home.

Essential Tools and Equipment

Before you get started, it's important to have the right tools and equipment on hand:

1. Pressure Washer‍

There are two types of pressure washers: electric and gas-powered. Electric pressure washers are suitable for small to medium-sized jobs, while gas-powered washers offer more power for tougher cleaning tasks.

2. Nozzles and Attachments

Different nozzles provide different spray patterns and pressure levels. A 0-degree nozzle offers a pinpoint spray, while a 40-degree nozzle provides a wider, gentler spray. Be sure to use the correct nozzle for the surface you're cleaning.

3. Detergent

Use a pressure washer-safe detergent for enhanced cleaning power. Some surfaces, like concrete or brick, may require specific types of detergents.

A common one that works extremely well is Sodium Hypochlorite, however it can be dangerous if used incorrectly (read our guide about Sodium Hypochlorite here).

4. Safety Gear

Always wear protective gear, including safety glasses, gloves, and sturdy footwear. Pressure washers are powerful tools that can cause injury if not handled properly.

Step-by-Step Guide

Preparation

1. Inspect the Area: Before starting, walk around your home and inspect the surfaces you plan to clean. Look for any cracks, loose siding, or areas that may be vulnerable to water damage. Repair these issues before pressure washing.
2. Protect Plants and Outdoor Furniture: Cover plants, outdoor furniture, and any delicate objects near the area to prevent them from getting damaged by the high-pressure water.
3. Close Windows and Doors: Ensure all windows and doors are tightly closed to prevent water from getting inside your home.

Set Up Your Pressure Washer

1. Connect the Water Supply: Attach your pressure washer to a water source and ensure the hose is securely connected.
2. Select the Appropriate Nozzle: Choose the right nozzle based on the surface you are cleaning. For example, use a 25-degree or 40-degree nozzle for siding and a 15-degree nozzle for concrete surfaces.
3. Add Detergent: If using detergent, fill the detergent tank on your pressure washer or attach a detergent bottle, following the manufacturer’s instructions.

Start Pressure Washing

1. Begin with a Test Spray: Before cleaning the entire surface, test the pressure washer on a small, inconspicuous area to ensure it won’t cause any damage.
2. Work from Top to Bottom: Start at the top of the house and work your way down. This prevents dirty water from streaking on already cleaned areas.
3. Keep a Safe Distance: Maintain a consistent distance between the nozzle and the surface, usually 3-4 feet. Holding the nozzle too close can damage the surface.
4. Use Even, Sweeping Motions: Move the nozzle in smooth, sweeping motions to avoid concentrating pressure in one spot for too long, which can cause damage.

Rinse and Finish Up

1. Rinse with Clean Water: After applying detergent and cleaning, switch to a clean water setting and rinse the entire surface thoroughly to remove any soap residue.
2. Inspect Your Work: Once you’ve finished, inspect the cleaned areas to ensure you didn’t miss any spots. If necessary, go over any stubborn areas again.

Clean Up

1. Turn Off the Pressure Washer: Disconnect the pressure washer from the water source, release any remaining pressure, and turn off the machine.
2. Store Equipment Properly: Allow hoses and nozzles to dry before storing them to prevent mold and mildew growth.

Safety Tips to Keep in Mind

• Avoid Ladders: Never use a pressure washer while standing on a ladder. The force of the spray can knock you off balance. Instead, use a pressure washer extension wand to reach high areas.
• Be Cautious with Windows and Vents: Avoid spraying directly into windows, vents, or electrical outlets. Water can penetrate these areas, leading to damage.
• Don’t Pressure Wash Painted Surfaces: Pressure washing can strip paint. If you’re planning to repaint, pressure washing is a great prep step, but be cautious around areas with older paint.
