How long does pressure washing a driveway last?
A professionally pressure washed driveway typically stays visibly clean for 6 months to a year, depending on your climate, tree coverage, and how much foot or vehicle traffic the surface sees regularly. Driveways in shaded, humid, or heavily wooded areas tend to develop algae and mildew faster, sometimes requiring touch-ups within just a few months, while driveways in drier, sunnier climates can often stay clean closer to the full year mark. Applying a concrete sealer after cleaning can meaningfully extend how long the surface stays clean, since sealed concrete resists staining and organic growth more effectively than untreated concrete. Routine light maintenance, like a quick rinse every few months, can also extend the interval between full professional cleanings, reducing how often deep cleaning is genuinely necessary.
