What should I expect to pay for deck staining on a 200-square-foot deck in Ottawa?

For a 200-square-foot deck in Ottawa, professional staining typically costs between $600 and $1,400, with most jobs landing in the $800 to $1,100 range. The wide spread depends on the deck's current condition, the product you choose, and how much prep work is required.

Here's the typical cost breakdown:

Labour: $400 to $900
Deck staining involves more prep than people expect. A proper job includes cleaning/power washing, sanding rough spots, possibly stripping old stain, and then applying the stain itself. For a 200-square-foot deck, expect 1 to 2 days of work.

Materials: $150 to $350
This covers the stain product, wood brightener/cleaner, sandpaper, masking materials, and application tools. A 200 sq ft deck typically needs 2 to 4 gallons of stain depending on the product and application method.

Stain product costs vary significantly:

• Semi-transparent oil-based stain (like Cabot Australian Timber Oil): $45 to $60/gallon — shows the wood grain, classic natural look


• Semi-transparent water-based: $40 to $55/gallon — easier cleanup, good UV protection


• Semi-solid stain: $45 to $65/gallon — more colour, still shows some texture


• Solid stain (essentially thin paint): $50 to $70/gallon — hides grain completely, most durable but looks painted


• Premium penetrating oil (like TWP or Armstrong-Clark): $55 to $75/gallon — deep penetration, excellent in harsh climates

Ottawa's extreme climate is the defining factor for deck staining. Your deck endures:

• -30°C winters with snow sitting on the boards for months


• 200+ cm of annual snowfall causing prolonged moisture exposure


• Freeze-thaw cycles that work moisture into every crack and end grain


• Intense summer sun and UV that breaks down the stain's binders and pigments


• Spring melt where standing water and ice can sit on deck surfaces for weeks

Because of this, penetrating oil-based stains tend to outperform film-forming products in Ottawa. Film-forming stains (solid stains and some semi-transparents) can peel and flake when moisture gets trapped beneath the film during freeze-thaw cycles. Penetrating stains soak into the wood and wear away gradually by erosion rather than peeling — they look better longer and are easier to recoat.

The staining window in Ottawa is relatively narrow. You need:

• Air temperature consistently above 10°C (ideally 15–25°C)


• Wood surface temperature below 30°C (too hot and the stain dries before penetrating)


• No rain for 24 to 48 hours after application


• Wood moisture content below 15% (after spring thaw, decks can stay wet into June)

Realistically, the best staining windows are late May through June and September through early October. Mid-summer works too but you need to avoid direct afternoon sun on the deck surface during application.

Prep work makes or breaks a deck stain job:

• New or bare wood: Clean, brighten with an oxalic acid wash, let dry thoroughly, then stain — relatively straightforward ($600 to $900 total for 200 sq ft)
• Previously stained, good condition: Clean, light sand, recoat — $700 to $1,000
• Peeling or failing old stain: Strip old stain (chemical stripper or aggressive sanding), clean, brighten, then restain — $1,000 to $1,400 because stripping is labour-intensive
• Greyed and weathered wood: Power wash with wood cleaner, sand, brighten, stain — $800 to $1,200

Don't forget the railings. If your 200-square-foot deck has railings on two or three sides, the spindles and railing caps can add $300 to $600 because of the tedious detail work — every spindle has four sides.

One thing Ottawa homeowners should know: deck staining is typically a maintenance item, not a one-time job. Even with premium products, Ottawa's climate means you'll want to restain every 2 to 3 years for semi-transparent products, or every 3 to 5 years for semi-solid and solid stains.
