What moves a deck price
Wood punishes carelessness: too much pressure furs the grain and leaves wand marks that only sanding fixes. Decks therefore price higher than concrete, and railings, balusters and stairs add real time. Composite decking tolerates a bit more pressure but still needs a soft approach. A 300 sq ft deck typically prices at $75–$150 — often a minimum-charge job unless bundled with a house wash.

Frequently asked questions
How much does it cost to pressure wash a deck?
Decks run $0.25–$0.50 per sq ft. A 300 sq ft deck typically costs $75–$150, and many contractors bundle it with a house wash to clear their minimum.
Can you pressure wash a wood deck safely?
Yes, at low pressure (under ~1,500 PSI) with a wide fan tip and detergent doing the work. High pressure scars soft wood permanently.
