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. At the published wood-surface range, a 300 sq ft deck prices at 300 × $0.30–0.55 = $90–$165 — 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 $0.30–$0.55 per sq ft for wood. At that range a 300 sq ft deck prices at $90–$165, 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 with a wide fan tip, letting the detergent do the work. High pressure furrs and scars soft wood permanently.
