People use "power washing" as a catch-all, but there are really two methods, and using the wrong one can do real damage. Here is how to tell which your home actually needs.
Power washing
Power washing uses high-pressure water to blast away grime, and sometimes heated water for grease and oil. It is the right tool for hard, durable surfaces:
- Concrete driveways and sidewalks
- Brick and stone
- Patios and pavers
If a surface can take the force, high pressure makes quick work of built-up dirt, mildew, and stains.
Soft washing
Soft washing uses low pressure and cleaning solutions that break down algae, mold, and mildew, then rinse clean. It is the right call for anything that high pressure could harm:
- Vinyl and wood siding
- Roofs and shingles
- Screens, soffits, and gutters
- Painted surfaces and decks
The cleaning power here comes from the solution, not the pressure, so it lifts the growth without forcing water behind siding or stripping a finish.
The simple rule
Match the method to the surface:
- Hard and durable (concrete, brick, stone) wants power washing.
- Soft or delicate (siding, roofs, wood) wants soft washing.
Get that backwards and you risk cracked siding, water damage, or a stripped finish. This is the main reason it pays to hire someone who knows which is which rather than renting a machine and guessing.
Why it matters for your home
Grime, algae, and mildew are not just ugly. On a roof or siding, organic growth holds moisture against the surface and shortens its life. Clearing it off with the right method protects the materials and brings your curb appeal right back.
A quick checklist before you book
- Walk the property and note what needs cleaning: driveway, siding, deck, roof.
- Flag anything delicate (old paint, wood, screens) so it gets soft washed.
- Ask whether the company adjusts pressure by surface. A good one always does.
