Keeping the exterior of your home clean is crucial for maintaining its beauty and structural integrity. Pressure washing is an effective method to remove dirt, mold, mildew, and grime from various surfaces. This guide will walk you through the process of pressure washing your house, ensuring you do it safely and efficiently.
Understanding Pressure Washing
What is Pressure Washing?
Pressure washing, also known as power washing, uses a high-pressure water spray to clean surfaces. The pressure washer can remove loose paint, mold, grime, dust, mud, and dirt from surfaces like buildings, vehicles, and concrete surfaces.
Why Pressure Wash Your House?
Regular pressure washing extends the life of your siding, driveway, deck, and other exterior surfaces. It also improves your home’s curb appeal, which is beneficial if you plan to sell your home. Moreover, it helps to prevent the buildup of harmful mold and mildew, which can cause health problems.
Types of Pressure Washers
There are two main types of pressure washers:
Electric Pressure Washers: These are suitable for smaller jobs and are generally quieter and more portable.
Gas Pressure Washers: These provide more power and are ideal for larger jobs but tend to be noisier and heavier.
Choosing the right pressure washer depends on the size of your cleaning job and the type of surfaces you need to clean.
Safety Precautions
Wear Appropriate Safety Gear
Before starting, wear safety goggles, gloves, and sturdy footwear to protect yourself from flying debris and high-pressure water jets. Hearing protection is also advisable, especially when using a gas-powered pressure washer.
Check the Surroundings
Ensure the area around your home is clear of obstacles, pets, and children. Move furniture, decorations, and any other objects that might get in the way or be damaged by water.
Read the Manual
Read the pressure washer’s manual thoroughly to understand its operation. Familiarize yourself with the controls and safety features.
Test the Washer
Before using the pressure washer on your house, test it on a small, inconspicuous area. This will help you get a feel for the pressure and ensure it won’t damage the surface.
Preparation Before Pressure Washing
Gather Necessary Supplies
Pressure washer
Garden hose
Extension cords (if needed)
Detergent (specifically for pressure washers)
Scrub brush
Drop cloths or plastic sheeting
Tape
Ladder (if needed)
Safety gear (goggles, gloves, sturdy shoes)
Protect Plants and Furniture
Cover plants, outdoor furniture, and electrical outlets with plastic sheeting or drop cloths to protect them from water and detergent.
Secure Windows and Doors
Ensure all windows and doors are closed tightly to prevent water from getting inside your home. Tape over any gaps if necessary.
Remove Obstacles
Clear the area around your home of any obstacles, including vehicles, toys, and garden equipment.
Steps to Pressure Wash Your House
1. Choose the Right Nozzle
Pressure washers come with various nozzles, each providing a different spray pattern and intensity. Use a nozzle that is appropriate for the surface you are cleaning:
0-Degree Nozzle (Red): Produces a pinpoint jet of water. Use with caution; it can damage surfaces.
15-Degree Nozzle (Yellow): Creates a narrow fan of water, suitable for removing tough stains.
25-Degree Nozzle (Green): Ideal for general cleaning tasks, such as washing your house’s siding.
40-Degree Nozzle (White): Provides a wide spray, best for rinsing and gentle cleaning.
Soap Nozzle (Black): Designed for applying detergent.
2. Attach the Garden Hose
Connect your garden hose to the pressure washer’s water inlet. Ensure the connection is secure to avoid leaks.
3. Add Detergent
Fill the pressure washer’s detergent tank with a suitable cleaning solution. Use detergents specifically formulated for pressure washers. Avoid using bleach or harsh chemicals, as they can damage your washer and the environment.
4. Start the Pressure Washer
Turn on the water supply from your garden hose. Start the pressure washer according to the manufacturer’s instructions. For electric models, plug in the machine and switch it on. For gas models, fill the tank with gasoline, prime the engine, and pull the starter cord.
5. Apply Detergent
Using the soap nozzle, apply the detergent to the house’s exterior. Work from the bottom up to prevent streaks and allow the detergent to soak into tough stains. Cover a small section at a time, ensuring even coverage.
6. Let the Detergent Sit
Allow the detergent to sit for 5-10 minutes, but do not let it dry. This will help loosen dirt and grime, making it easier to wash away.
7. Scrub Stubborn Stains
For areas with stubborn stains, use a scrub brush to agitate the surface before rinsing. This is especially important for mold, mildew, and algae buildup.
8. Rinse with Clean Water
Switch to a general-purpose nozzle, such as the 25-degree or 40-degree nozzle. Rinse the detergent and dirt from the house, working from the top down. This helps prevent streaking and ensures all soap residue is washed away.
9. Clean the Windows
After rinsing the house, clean the windows with a glass cleaner to remove any streaks or residue left by the pressure washer.
Specific Surfaces and Considerations
Vinyl Siding
Vinyl siding is durable and can withstand pressure washing. However, use a moderate pressure setting to avoid damage. Hold the nozzle at a slight angle to prevent water from getting behind the siding.
Wood Siding
Wood siding is more delicate than vinyl and requires a gentler touch. Use a lower pressure setting and a wider spray nozzle to avoid gouging the wood. Always move the nozzle in the direction of the wood grain.
Brick and Stucco
Brick and stucco surfaces can handle higher pressure but be careful around mortar and joints. Use a 25-degree nozzle for these surfaces and keep the nozzle at a consistent distance from the surface.
Concrete and Driveways
Concrete and driveways can withstand high pressure. Use a 15-degree nozzle for tough stains and a 25-degree nozzle for general cleaning. Keep the nozzle moving to avoid etching the surface.
Decks and Patios
For wooden decks, use a low-pressure setting and a 40-degree nozzle to avoid damaging the wood. For concrete patios, a higher pressure setting with a 25-degree nozzle works best.
Maintenance and Aftercare
Clean the Pressure Washer
After using your pressure washer, clean it thoroughly. Rinse the detergent tank, hoses, and nozzles to prevent clogs and buildup. For gas models, run fresh water through the system to remove any remaining detergent.
Inspect Your Home
After pressure washing, inspect your home for any damage. Check for loose siding, chipped paint, or other issues that may need repair.
Store the Equipment
Store your pressure washer in a dry, secure location. For electric models, coil the power cord neatly. For gas models, empty the fuel tank or add a fuel stabilizer to prevent the gasoline from going stale.
Plan Regular Cleaning
Regular pressure washing helps maintain your home’s appearance and prevent long-term damage. Plan to pressure wash your home at least once a year, or more often if you live in an area with high humidity or pollution.
Troubleshooting Common Issues
Inconsistent Pressure
If your pressure washer has inconsistent pressure, check the water supply and hoses for kinks or leaks. Clean the nozzle and inlet filter to remove any debris.
No Water Flow
If no water flows from the pressure washer, ensure the water supply is turned on and the hose is properly connected. Check for clogs in the hose, nozzle, or inlet filter.
Detergent Not Dispensing
If the detergent isn’t dispensing, check the detergent tank and siphon tube for clogs. Ensure you’re using the correct soap nozzle.
Engine Won’t Start (Gas Models)
If the engine won’t start, check the fuel level and spark plug. Make sure the choke is in the correct position and the engine is primed.
Conclusion
Pressure washing your house is a rewarding task that can greatly enhance your home’s appearance and longevity. By following this comprehensive guide, you can safely and effectively clean your home’s exterior, ensuring it remains beautiful and well-maintained for years to come. Remember to always prioritize safety, use the correct equipment and settings, and perform regular maintenance to keep your pressure washer in good working condition.
