Deck Staining Prices in Ontario (2026)

Deck staining costs in Ontario are driven primarily by the square footage of the deck surface, the condition of the existing finish, and the type of stain applied. A small, clean cedar deck may require only a wash and one coat, while a large pressure-treated deck with a failing previous finish needs full stripping, sanding, and two coats — a significantly more involved job. Pricing below includes labour and materials for a professional finish.

Stain Type and Finish Options: Costs Compared

The stain you choose affects both the upfront cost and how long the finish will last before recoating is needed. Semi-transparent stains allow the wood grain to show through and typically last 2–3 years on horizontal surfaces. Solid stains provide the most UV and moisture protection, lasting 3–5 years, but require more thorough prep and full stripping when it is time to recoat. Premium brands such as Cabot, Defy, and TWP command higher material costs but often reduce recoat frequency.
