I get this question all the time: What’s the difference between pressure washing and power washing? If you're a homeowner in the Salt Lake Valley, you know our seasons can be rough on the outside of your home. Between dusty summers, snowy winters, and all that in between, grime builds up fast. And when it’s time to clean it off, you want to do it right.
This guide is here to break it all down for you in plain language. We'll talk tools, surfaces, safety, and help you make the best choice for your home’s needs.
Why It Matters: Pressure Washing vs Power Washing
Knowing the difference between pressure washing and power washing isn't just about being technical. It's about protecting your biggest investment: your home. Using the wrong method can mean damaged siding, cracked concrete, or even voided warranties.
Choose the right one and you’ll get a deep clean that restores curb appeal without wrecking your surfaces.
What Is Pressure Washing?
Pressure washing uses high-pressure water to blast away dirt, mold, mildew, and grime. It does not use heated water.
How It Works
A pressure washer pumps cold water through a high-pressure hose and nozzle. The water pressure is what does the heavy lifting, breaking apart and washing away built-up debris.
Typical PSI Range
Pressure washers generally range from 1,300 to 3,200 PSI (pounds per square inch). The higher the PSI, the tougher the clean.
Common Surfaces for Pressure Washing:
- Vinyl siding
- Wood fences and decks
- Patio furniture
- Vehicles
- Brick pathways (light grime)
Pros:
- Uses less energy (no heating element)
- More affordable to operate
- Easier on delicate surfaces
Cons:
- Less effective on grease and oil stains
- Can take longer on tough grime
- Not suitable for deep-rooted mold or mildew
What Is Power Washing?
Power washing is similar to pressure washing but with one key difference: it uses heated water.
How It Works
Power washers heat water to about 200°F or more before it’s blasted out under pressure. That added heat helps break down stubborn substances like grease, salt, or thick mildew.
Typical PSI Range
The pressure range is often comparable to that of pressure washers, but with the added benefit of heat.
Common Surfaces for Power Washing:
- Concrete driveways and garage floors
- Brick or stone walls with deep mold
- Oil-stained surfaces
- Commercial buildings
Pros:
- More effective at removing grease, oil, and salt
- Great for winter residue and salt damage
- Sanitizes surfaces
Cons:
- Uses more energy (heating element)
- Can damage soft surfaces
- Higher equipment cost
Equipment Differences
Let’s talk gear. As a professional, I use both types of machines, depending on the job. But here’s what makes each one different:
Pressure Washing Equipment
- Cold water pump
- High-pressure hose and nozzle
- Detergent tank (optional)
Power Washing Equipment
- Hot water heater (gas or electric)
- Pump and high-pressure hose
- Adjustable nozzle for different surfaces
Best Use Cases by Surface & Condition
Here’s a quick guide to help you match the method with the mess:
Use Pressure Washing For:
- Wood siding: Safe on soft materials
- Outdoor furniture: Gentle enough for plastics
- Decks and fences: Clean without stripping finishes
- Pavers and walkways: Light dirt and algae
Use Power Washing For:
- Concrete driveways: Blast through oil stains
- Garage floors: Remove winter salt buildup
- Brick walls: Clean out tough mildew and moss
- Industrial exteriors: Remove graffiti or caked-on grime
Side Effects and Risks
Choosing the wrong method can cost you. I've seen plenty of DIY disasters that could have been avoided.
Pressure Washing Risks
- Splintered wood if nozzle is too close
- Chipped paint from high PSI
- Cracks in old mortar on brick homes
Power Washing Risks
- Warped siding from heat
- Damaged sealants on wood or concrete
- Injury risk from hot water spray
Decision-Making Checklist
Not sure which way to go? Here’s a simple checklist:
1. What are you cleaning?
- Wood, vinyl, plastic → Pressure Wash
- Concrete, brick, oil stains → Power Wash
2. How dirty is it?
- Light dust, dirt, or cobwebs → Pressure Wash
- Deep-set stains, grease, or salt → Power Wash
3. What’s the weather like?
- Cold weather? Heated water works better → Power Wash
- Warm dry season? → Pressure Wash may be all you need
4. Are there any special coatings or finishes?
- Painted or sealed surfaces? Stick with Pressure Wash
- Unfinished concrete? Go with Power Wash
Post-Cleaning Maintenance Tips
After your home gets a deep clean, you want those results to last. Here’s what I recommend to my clients:
Seal It Up
- Wood decks: Reseal once a year
- Concrete driveways: Seal every 2–3 years to prevent oil soak-in
- Brickwork: Use breathable masonry sealants to avoid moisture trap
Re-Coat Painted Areas
- Inspect for chipped or worn paint
- Touch up after washing to keep it looking fresh
Set a Cleaning Schedule
- Spring: Perfect time for pressure washing
- Fall: Use power washing to prep surfaces for winter
Regular Inspections
- Check siding, gutters, and walkways twice a year
- Look for cracks, mildew, and buildup early before it becomes a problem
