Pressure Washing vs Power Washing: What's the Difference?
People search for both terms and usually mean the same thing: cleaning outdoor surfaces with pressurized water. There is a technical difference, though, and it affects which method belongs on which part of your property.
The technical difference
Pressure washing uses unheated pressurized water. Power washing adds heat. Hot water helps break down grease and heavy grime, which is why it shows up more in commercial and industrial work than on a typical home.
Why the term matters less than the technique
For most Chattanooga homes, the real question is not hot versus cold — it is how much pressure hits the surface and whether growth is treated first. Concrete tolerates a surface cleaner. Wood and composite need lower pressure and a gentler approach, or they get permanently marked.
A quick surface guide
- Driveways, sidewalks, steps, pool decks: surface cleaner, even overlapping passes.
- Decks and fences: lower pressure, wide fan, work with the grain, then seal once dry.
- Pavers and stone patios: controlled pressure, plus care not to blow out joint sand.
