What affects the cost of deck or patio pressure or power washing?
Square footage
Deck and patio washing is priced largely by area, with railings and stairs adding surface for their size.
Surface material and pressure
Wood decking needs lower pressure and careful technique to avoid furring the boards; concrete and pavers tolerate more.
Growth and staining
Heavy algae, mildew or grill grease usually needs a cleaning solution and dwell time before rinsing.
Local labor rates
Rates vary market to market. Your quote reflects what the pro in your ZIP actually charges — not a national guess.
