Deck Staining & Sealing Winnipeg

Deck staining in Winnipeg costs $400–$1,500 for a typical deck, and the only way to survive a Manitoba winter is with full prep and a penetrating stain that flexes with the freeze-thaw cycle. Deck Staining Winnipeg is a deck-only crew, we don't paint houses or wallpaper rooms. We clean, sand, brighten, repair, and apply two coats of premium penetrating stain (Sikkens or TWP) that moves with the wood instead of cracking like a film coating.

What's included in every deck staining job

Every job starts with a full inspection, not a quick once-over. Winnipeg's gumbo clay soils shrink and swell with every freeze-thaw cycle, so posts shift, joists settle, and fasteners loosen. We check for lifted boards, popped nails, and any structural movement before we touch a brush.

The prep is where the job is won:

• Cleaning and power washing, strips mildew, grime, and the pollen layer that settles on decks near Assiniboine Park and the river.
• Sanding, smooths splintered surfaces and opens the wood grain so the stain actually penetrates.
• Brightening, an oxalic acid wash that removes grey oxidation and brings cedar back to its natural colour.
• Repairs, we replace damaged boards, reset fasteners, and level sections that have settled.

Only then do we stain. Two brushed coats of Sikkens or TWP, brushed on, not sprayed. Spraying looks fast but leaves thin coverage in the valleys; brushing works the stain deep into the grain, which is what keeps it from peeling when the temperature swings 40 degrees in a week.

Deck staining and sealing prices in Winnipeg

Pricing depends on square footage, condition, and whether you need a basic re-coat or a full restoration. what you can expect across the Winnipeg area:

• Deck Staining & Sealing, $400–$1,500
• Deck Sanding & Restoration, $600–$2,000 (for grey, weathered, or previously coated decks that need deep prep)
• Fence Staining & Painting, $300–$1,200
• Deck Cleaning & Power Washing, $150–$400

A well-maintained cedar deck that just needs a re-coat lands in the $400–$800 range. A deck that hasn't been touched in five years, grey, rough, with peeling old coating, runs $800–$1,500 because the prep work is heavier. We'll tell you which category you're in before we start, and the quote is fixed.

We also stain fences with the same standard. If your fence and deck are both due, we'll bundle them into one visit and one contract.

Our process: from gumbo clay to finished coat

Winnipeg decks fight a specific battle. The soil under your posts moves with every freeze-thaw, the humidity swings from bone-dry January air to July afternoons at 95% relative humidity, and the UV in summer is relentless. Film-forming paints crack under that stress. Penetrating stains soak in and flex with the wood, that's why we use them.

how we work:

1. Inspection and quote. We walk the deck, note the condition, check for structural movement, and give you a fixed quote within 48 hours. No pressure, no upsell.

2. Prep. Clean, sand, brighten, repair. This is where the finish is decided, a properly prepped deck holds stain for years; a painted-over coat peels in one season.

3. Stain. Two brushed coats of Sikkens or TWP. We'll match your existing colour or go with a natural cedar tone if you want the original look.

4. Seal. The second coat seals against water and UV. Expect 3–6 years on a properly prepped deck, and we'll tell you exactly when to plan the next refresh.

Why choose us

We only do decks. No houses, no fences-turned-hobby, decks are our full-time job. Every crew member has stained dozens of Winnipeg decks, from cedar to pressure-treated to composite.

Premium penetrating stains, not box-store paint. Sikkens and TWP are formulated for flex with the freeze-thaw cycle. A $2 film of deck paint from a big-box store will crack in one winter. We don't use it.

Full prep, not a coat of paint. If we can't get your deck to a condition where the stain will hold, we'll tell you before we start, not after.

Warranty that survives a Manitoba winter. We back our work. If the finish fails due to our prep or application, we fix it.

We serve Winnipeg and the surrounding bedroom communities, from the Exchange District to the lake suburbs, and the same standard applies whether your deck is steps from The Forks or tucked behind a home in Assiniboine Park.
