Deck Paint vs Deck Stain — Cost Comparison

Deck stain typically costs the same as deck paint per gallon ($30–$60) but is more economical long-term because it is easier to reapply — no stripping required. Paint can peel and may require stripping before recoating, adding $200–$600 in prep cost to the next paint job.

For a new deck, stain is the more cost-effective long-term choice. For an existing painted deck, repainting is usually more practical than stripping back to bare wood.

What Adds Cost to a Deck Paint Job?

Deck condition. Weathered or peeling decks need power washing, sanding, and possibly board replacement before painting — adding $100–$400 to prep costs.

Railings and stairs. Railings and stairs take proportionally more time than flat deck boards — add 30–50% to the deck estimate for comprehensive railing and stair painting.

Two colours. Using a different colour for railings vs deck boards requires masking and adds $100–$200 professionally.
