How to Pressure Wash a House
Pressure washing your house is not just about blasting dirt away. It’s a task that requires patience, effort, and a bit of know-how.
While it’s an efficient way to refresh your home’s exterior, it’s not as simple as pointing a hose and watching the magic happen. This method can breathe new life into various surfaces like stucco, wood, and brick. But remember, it’s not a one-size-fits-all solution.
In this guide, we’ll cover the steps to get your house looking its best. From preparing your home and setting up the washer, to the actual washing and post-care. We’ll answer common questions and offer tips to ensure a successful clean. Whether you’re a first-timer or looking to refine your technique, this article is here to help.
Let’s step into the world of pressure washing and start the journey to a cleaner, brighter home.
- Right Equipment Matters – Choosing between a gas or electric pressure washer is key. The right choice depends on your house size and cleaning needs. Remember, different surfaces require different pressure levels.
- Safety First – Always wear protective gear like goggles and gloves. Be mindful of your surroundings to avoid accidents. Remember, pressure washers are powerful and should be handled with care.
- Preparation is Essential – Before starting, cover plants and close all windows and doors. This protects your home and greenery from water damage and cleaning solutions.
- Technique Counts – Apply detergent from the bottom up and rinse from the top down. This method ensures an even clean and prevents streaks. Tackle your house in sections for a thorough job.
- Mind the Weather – Choose a mild day for pressure washing. Too much sun can cause the water to dry too quickly, leaving spots.
- Post-Wash Care – After washing, if you’re painting, let your house dry completely. This ensures the paint adheres well and lasts longer.
- Professional Help Is an Option – For multi-story homes or if you’re unsure about doing it yourself, consider hiring a professional. They have the expertise and equipment to handle the job safely and efficiently.
Choosing the Best Pressure Washer
Choosing the right equipment for pressure washing your house is crucial. It’s not just about power, but also about suitability and safety.
The type of pressure washer you select can make a big difference in both the ease and effectiveness of the job.
There are two main types of pressure washers: gas and electric.
Gas models are known for their strength and mobility. They don’t need a power outlet, so you can move around freely. This makes them a good choice for larger homes or areas without easy access to electricity.
Electric models, on the other hand, are less powerful but more convenient for smaller tasks. Models like the Karcher K2 below are easier to handle and ideal for those who are new to pressure washing.
The power of a pressure washer is measured in pounds per square inch (PSI). This tells you how much force the water will hit the surface with.
Different materials require different PSI levels. For instance, delicate materials like painted wood need a lower PSI to avoid damage, so starting around 500 PSI is usually best and working up to prevent damage. More robust materials like brick can handle a higher PSI.
It’s important to get this right. Using too high a PSI can harm your home’s exterior, stripping paint or damaging siding. Too low, and you might not clean effectively. If you’re unsure, it’s always safer to start lower and increase the pressure gradually.
Another key factor is the pressure washer nozzle. The angle of the nozzle affects how concentrated the water stream is. A wider angle means a softer spray, which is better for delicate surfaces. Narrow angles increase the intensity and are better for tougher jobs.
Here’s a handy summary of various nozzle types:
- 0-degree high-intensity jet nozzle (red): Delivers a highly concentrated pencil-point jet stream to whatever you’re cleaning, and is ideally suited to moving the most stubborn of dirt.
- 15-degree fan-tip nozzle (yellow): For particularly intense cleaning tasks on hard surfaces, for example, stripping paint, cleaning grease, or removing rust from steel.
- 25-degree fan-tip nozzle (green): For a variety of household tasks, for example, cleaning brick patios, wooden decks, and driveways.
- 40-degree wide-spray nozzle (white): For cleaning more delicate items, for example, cars, boats, patio equipment, lawn mowers, etc.
- Soap nozzle (black): Specifically designed for when you’re using detergent. The lower pressure is ideal for cleaning equipment, removing mildew/oxidation stains from houses, and cleaning bricks, etc.
The color scheme for pressure washers is fairly standard and makes it easy to choose the correct one.
If you’re planning to buy a pressure washer, talk to experts at your local hardware store. They can guide you to the right model for your needs. If you’re renting, the rental agency can provide valuable advice on which machine and settings are best for your home.
In summary, picking the right pressure washer and settings is about balancing power with precision. It’s about matching the tool to the task at hand, ensuring you clean effectively without causing damage. With the right equipment, pressure washing can be a satisfying and productive experience.
Preparing Your House for Pressure Washing
Getting your house ready for pressure washing is a key step you shouldn’t overlook. Proper preparation can prevent damage and make the cleaning process smoother and more effective. Here’s how you can set the stage for a successful pressure wash.
First, consider the surroundings of your house. Cover any plants, shrubs, or garden areas close to the walls. You can use plastic sheeting or drop cloths for this. Securing these covers with duct tape will ensure they stay in place. This step is crucial to protect your greenery from the powerful spray and any cleaning solutions used.
Next, turn your attention to the house itself. Close all windows and doors tightly. This is important to prevent water from getting inside your home. Double-check them to make sure they’re securely shut. Pay special attention to small cracks and openings where water can sneak in.
If you spot any mold or mildew on your home’s exterior, treat these areas before you start. A simple solution of bleach and water works well on hard, non-porous surfaces. Apply it with a spray bottle, gently brush the area, and rinse with clean water.
For porous surfaces such as wood, undiluted vinegar is a better option than bleach. Let the vinegar sit on the surface for 60-minutes to air dry before wiping away any excess.
These pre-treatments will help remove these stubborn spots more effectively during any follow-up pressure washing.
Clearing the area around your house is also vital. Remove any obstacles like bikes, toys, and outdoor furniture. These items can get in the way and might get damaged. Also, move your car out of the driveway to keep it safe from dirt and debris.
For houses with more than two stories, setting up scaffolding is a smart move. It’s safer than using a ladder (which we never recommend), as the force of the water can throw off your balance. Scaffolding provides a stable platform, allowing you to reach high areas without the risk.
In essence, preparing your house for pressure washing is about safeguarding both your property and the environment around it.
By taking these steps, you ensure a safe, efficient, and hassle-free cleaning process.

Post-Wash Care and Painting Prep
After pressure washing your house, there’s a sense of accomplishment. Your home looks refreshed, but the job isn’t done yet. There are a few post-wash actions you need to take, especially if you plan to paint your house.
These steps are crucial for ensuring your home is ready for a new coat of paint and stays in great condition.
First, inspect your house for any areas that might need more attention. Sometimes, pressure washing reveals spots that require extra cleaning or even repairs. This is particularly true for older homes where the high pressure might have uncovered hidden issues.
If you’ve used detergent, make sure to rinse your house thoroughly. Any residue left behind can interfere with the new paint adhering properly. Think of it as preparing a canvas for painting; it needs to be clean and smooth.
Give your house time to dry completely. This is crucial. Painting on a damp surface can lead to peeling and bubbling. Ideally, wait for a dry, warm week to ensure all the moisture has evaporated. This patience pays off with a paint job that lasts longer and looks better.
Lastly, check for chalking. Older paint might have left a powdery residue. You’ll want to remove this before painting to ensure the new paint adheres well. It’s similar to sanding down a piece of furniture before repainting it.
By taking these post-wash steps, you’re not just cleaning your house; you’re preparing it for a fresh start. Whether you’re repainting or just enjoying the renewed look of your home, these actions help maintain its beauty and value.
With your house clean, dry, and ready, you can move forward with confidence, knowing you’ve laid the groundwork for a successful painting project or simply for enjoying your revitalized home.

When considering pressure washing your house, it’s important to think about the costs involved and whether to do it yourself or hire a professional.
Both options have their benefits, and the best choice depends on your situation, budget, and comfort level with the task.
Let’s compare DIY versus professional pressure washing:

Frequently Asked Questions
When it comes to pressure washing, many homeowners have questions. It’s natural to want to know more about this process, especially if you’re doing it for the first time.
What Should I Do to Prepare My House for Pressure Washing?
Preparing your house for pressure washing is like getting ready for a big paint job.
First, protect your plants and garden areas with plastic sheeting or drop cloths. Then, make sure all your windows and doors are closed tightly. You don’t want any water sneaking inside.
If you see any mold or mildew, treat those areas with a mix of bleach and water on hard surfaces, or with undiluted vinegar on porous surfaces such as wood.
Next, clear the area. Move anything like bikes or outdoor furniture that could get in the way or damaged.
Lastly, if your house is more than two stories, consider setting up scaffolding instead of using a ladder. It’s safer because the force of the water can make ladders risky.
How Do I Choose the Right Pressure Washer and Settings for My House?
Choosing the right pressure washer is like picking the perfect tool for a DIY project. You have two main types to choose from: gas and electric.
Gas models are powerful and great for bigger jobs, but they’re also louder and heavier. Electric models are easier to handle and better for smaller tasks.
Then there’s the pressure setting, measured in PSI. Use a lower PSI for delicate surfaces to avoid damage. For tougher surfaces, like brick, you can go higher. The key is to start low and gradually increase the pressure.
Also, consider the nozzle. Wider angles are gentler, while narrow angles are more intense. It’s all about finding the right balance for your home.
Can Pressure Washing Damage My Home?
Yes, pressure washing can damage your home if not done correctly. It’s a powerful tool, and just like using a power drill, you need to be careful.
The high pressure can strip paint, dent siding, or even break windows if you’re not careful.
To avoid damage, use the right pressure setting for your home’s material. Stay at a safe distance from the surface, and never use a zero-degree nozzle on siding. Also, keep the spray away from windows and doors.
If you’re not confident, it might be safer to call in a professional, especially for delicate materials or hard-to-reach areas.
How Often Should I Pressure Wash My House?
Think of pressure washing like a regular health check-up for your house.
It’s good to do it every few years to keep your home looking fresh and clean. It also helps protect your house by removing harmful things like mold, mildew, and built-up dirt.
If you’re planning to repaint, you’ll definitely want to pressure wash first to prepare the surface. For areas with a lot of trees or exposure to pollution, you might need to do it more often.
Keep an eye on your home’s exterior; if it starts looking a bit grimy, it’s time for a wash.
What Are the Key Safety Tips for Pressure Washing?
Safety in pressure washing is non-negotiable, like wearing a seatbelt in a car.
Always wear protective gear, like goggles and gloves. Check your equipment before starting, especially for any leaks or damage. Be aware of your surroundings – keep kids and pets away, and watch out for things like electrical wires. Use the right pressure settings and nozzles to avoid damaging your house.
Also, never point the pressure washer at people or pets, as the high pressure can cause serious injuries.
Lastly, avoid using ladders. The kickback from the washer can make you lose your balance. If you need to reach high areas, use an extension wand instead.
It’s always better to be safe than sorry.
