Jared from newportpressurewash.com says “Pressure washing services can take anywhere from 2-6 hours depending on what the job entails. If it is a full house wash, driveway cleaning and roof cleaning, it will take up to 6 hours if not more. But if it is just a driveway cleaning, only about an hour or so to finish the job. Having better equipment helps get the job done quicker and more thoroughly.”
