How long does it take to power wash a driveway?
For a professional crew, power washing a standard 2-car driveway typically takes 1 to 2 hours, including setup, cleaning, and rinsing. Larger or longer driveways, decorative concrete, or surfaces with heavy oil staining requiring pretreatment and dwell time can extend the job to 2–3 hours. DIY jobs generally take longer than professional estimates, often adding 30 minutes to an hour for equipment setup, more cautious technique on unfamiliar equipment, and multiple passes to achieve the same result a commercial-grade machine accomplishes in one. Applying a sealer afterward, if you choose to, adds additional time beyond the cleaning itself, since the concrete needs to be completely dry first. Factoring in landscaping protection and cleanup on either end gives a more realistic total time estimate than the active washing time alone.
