How long does it take to pressure wash a 2500 sq ft house?

For a professional crew, pressure washing a 2,500 square foot house exterior typically takes 3 to 5 hours, depending on siding material, home height, and buildup severity. Straightforward vinyl siding in reasonable condition sits toward the shorter end of that range, while multi-story homes, heavy algae staining, or surfaces requiring soft washing — which involves a chemical dwell time before rinsing — push the job closer to 5 hours or beyond. DIY jobs generally take noticeably longer than professional estimates, often adding an extra hour or two for setup, more cautious technique, and unfamiliarity with the equipment. Factoring in landscaping protection, ladder or extension wand setup for upper stories, and cleanup afterward gives a more realistic total time estimate than the washing time alone.
