Is pressure washing driveways a good idea?

Yes, for the vast majority of homeowners, pressure washing a driveway is a genuinely worthwhile investment. Concrete is one of the most forgiving surfaces for pressure washing, tolerating higher PSI than siding, wood, or roofing without significant damage risk when done correctly. Regular cleaning, roughly once or twice a year, prevents oil stains, algae, and grime from becoming permanently embedded in the concrete’s porous surface, which becomes progressively harder and more expensive to remove the longer it’s left untreated. Beyond appearance, a clean driveway also reduces slip risk from algae buildup, which matters in wet or shaded areas. The main caution is around older, cracked, or already-weakened concrete, and the mortar joints on paver driveways specifically, both of which benefit from more moderate pressure than a routine cleaning would otherwise use.
