Your driveway looks like it’s seen better days, and the siding? Let’s just say it’s not its original color. Between power washing and pressure washing, what’s your best bet?
Understanding the difference between the two, which lies in using heated water, could save you both time and money.
This guide walks you through which method is best for everything from roofs to whole-house cleaning. And to make it even more helpful, I’ve included some tried-and-true tips from my colleagues who’ve been there, done that — because sometimes, the best insights come from real people who know what works.
Difference Between Power Washing and Pressure Washing
While both pressure washing and power washing involve using high-pressure water to clean, the key difference is the heating element.
Power washing uses hot water, typically with a PSI (pounds per square inch) range of 2,000 to 4,000, while pressure washing does not use heated water, with a PSI range between 1,300 to 3,000. This temperature difference influences which method is best for your cleaning job.

Which is Best for Your Cleaning Needs?
To help you better understand, here’s how each cleaning method works best for specific tasks:
- Driveways: Pressure washing can work. My colleague Sarah shared that her dad uses a gas pressure washer to keep their concrete driveway spotless. But if you’re dealing with greasy stains or built-up grime, power washing is your best bet due to the hot water, which breaks down grease faster than cold water.
- Sidewalks: Keep sidewalks looking fresh and clean with regular pressure washing. For tougher stains or high-traffic areas, power washing works best.
- Siding: For vinyl siding, pressure washing is effective, but it’s crucial to use the correct pressure settings to avoid damage.
But for older or more delicate siding like wood, stucco, and aluminum, soft washing, a method that uses low-pressure water and gentle cleaning solutions, may be a safer alternative.
Tip: My colleague Harley shared that spraying sideways rather than upwards will prevent water from seeping under the siding.

However, power washing works best in tackling deep stains and heavy grime.
- Fences: Pressure washing works for light cleaning jobs, but power washing is a great way to blast away dirt and grime from your fence and give your property a cleaner, more polished look.
- Gutters: Pressure washing works well here, especially when paired with a controlled nozzle attachment to avoid water damage to surrounding areas.

- House: If you’re cleaning your entire house, pressure washing is an excellent choice.
As my colleague Harley notes, “Pressure washing can make your home look like it’s been freshly painted.” She recommends it for removing mold, mildew, and dirt, especially for those in northern regions where shady sides of houses often develop green mildew. Sarah agrees — it’s been great for their house’s brick walls, too.
Beware the Risks
While both power washing and pressure washing are effective, they come with risks if not used properly. Without the right knowledge or equipment, you could end up doing more harm than good.
| Method | Potential Risks |
| Pressure Washing | • Can damage siding, crack concrete, or strip away paint if not done correctly • Risky for softer materials like wood or certain types of brick • Powerful spray can etch concrete surfaces, such as driveways |
| Power Washing | • High heat can warp or crack surfaces like vinyl siding • Older or painted vinyl siding is particularly vulnerable to heat damage that can can be difficult to fix |
Why You Might Want a Pro
Professionals are trained to safely navigate these risks. They know the correct pressure and temperature settings for different surfaces. Plus, they have the right equipment, like specialized nozzles and surface protectors, to ensure nothing gets damaged.
They also have insurance, so you don’t have to worry about any accidental damage to your property. And when it comes to tricky areas like roofs and gutters, pros use the right techniques to clean without putting your home at risk.
Hiring a Pro: Cost Comparison
| Pressure Washing | Power Washing |
| Professionals charge around $210 to $390 per project or about $0.15 to $0.50 per square foot. Prices can vary significantly based on the project, the materials involved, and the size of the area being cleaned. | When hiring a pro, power washing typically costs between $170 and $360 for jobs like house washing, with pricing ranging from $0.40 to $0.55 per square foot. For more complex tasks requiring hot water, such as removing tough stains or mildew, the cost tends to be on the higher end. |

FAQ
Soft washing is a gentler cleaning method that uses low-pressure water (typically under 500 PSI) combined with specialized cleaning solutions.
Unlike pressure washing, which can cause damage to delicate surfaces, soft washing uses a mild approach to clean thoroughly without harming the surface underneath.
Soft washing is an ideal method for cleaning delicate surfaces like:
• Roof shingles or tiles (soft washing is especially recommended for these)
• Siding made of wood, aluminum, stucco or other delicate materials
• Other surfaces like stucco walls and even outdoor furniture (though pressure washing can be used for these in some cases).
Yes. Most homeowners can manage pressure or power washing as a DIY project if they have the right equipment. The process is typically straightforward — set up the machine (whether electric or gas-powered), connect the hose, and start cleaning.
However, it’s important to follow safety guidelines and use the correct settings for your surface to avoid damage or injury. Here’s what you should be cautious about:
• The high-pressure blast can damage delicate surfaces like wood or painted areas if not used properly.
• Improper handling can lead to serious injuries. It’s important to read the manufacturer’s instructions and wear protective gear when operating a pressure or power washer.

The Right Wash for The Job
At the end of the day, whether you choose power washing or pressure washing boils down to your specific needs and the surfaces you’re cleaning.
If you’re tackling grease-stained driveways or heavy grime, power washing’s heated water is the best for the job. For more delicate surfaces like siding or decks, pressure washing offers the cleaning power without the added heat risks.
