Deck staining and sealing in St. Boniface starts at $400 and typically runs $400–$1,500 for a standard deck — and that price includes full prep (sanding, brightening, repairs), not just a coat of paint over last year's peeling finish. If your deck sits on a river property near the Red River or the Provencher Bridge, prep matters even more: high-water years leave silt and salt residue in the wood that will reject any new stain unless it's stripped out first.
What's included in a St. Boniface deck service
Every deck we stain in St. Boniface gets the same treatment, regardless of size:
- Full structural inspection — joists, posts, railings, and any soft spots
- Cleaning with a deck-specific cleaner (not a house pressure washer)
- Oxalic acid brightening to restore the natural cedar tone
- Sanding to remove old finish and open the wood grain for the stain
- Repairs: cracked boards, popped nails, loose railings — fixed before we stain, not after
- Two coats of premium penetrating stain on horizontal surfaces, one coat on verticals
- Cleanup and disposal of all debris
We use Sikkens and TWP penetrating stains only. Film-forming paints and deck coatings crack in Winnipeg's freeze-thaw cycle — the wood moves, the film doesn't, and you get peeling within a year. Penetrating stains soak into the wood and flex with it, which is the only approach that survives a Manitoba winter.
What's different about St. Boniface decks
St. Boniface isn't like the rest of Winnipeg. The river lots have gumbo clay soil that swells when wet and shrinks when dry — your deck moves every season, and that movement transfers straight to the boards. The older homes in the French Quarter, around the St. Boniface Cathedral, often have French-timber styling: thick cedar posts, hand-cut railings, and decorative brackets. Those details need individual attention — you can't just roll a wide paintbrush over them and call it done.
And then there's the flood history. If your property is on the river, you've likely seen high-water years. Even after the water recedes, the silt and salt residue stay embedded in the wood. Stain over that and it will peel — guaranteed. We strip the residue first, neutralize the surface, and then apply the stain. It's extra work, but it's the only way to get a finish that lasts more than one season.

How the process works
1. Free quote within 48 hours. We come to your home, inspect the deck, and give you a fixed price. No pressure, no "discovery" charges later.
2. Prep day. We sand, brighten, repair, and clean. This is the step most painters skip — and it's the step that determines whether your stain survives the winter.
3. Stain day. We apply the premium penetrating stain — two coats on horizontal surfaces, one on verticals. We hand-brush every edge, corner, and profile piece; we don't just roll over the whole deck.
4. Walkthrough. We walk the deck with you, check coverage, and fix anything that looks off before we leave.
Why St. Boniface homeowners choose us
We're a deck-only crew. We don't paint houses, we don't wallpaper rooms, and we don't take on a deck as a side job between renovations. Decks are all we do — and it shows in the prep.
We're a Winnipeg team that knows the terrain. The freeze-thaw cycle, the clay soil, the UV summer, the river silt — we've seen it all on decks across the city and the surrounding communities. We don't use products that work in a rare climate; we use products proven to survive a Manitoba winter. That's why we use Sikkens and TWP penetrating stains, and why we warranty our work for a full year — including against cracking and flaking.
If your deck hasn't been stained in a while, our sanding and restoration service will bring it back to life. We'll strip the old finish, sand the wood down to a clean surface, repair damaged boards, and re-stain with a penetrating product. It's more work than a simple re-coat, but it's the difference between a deck that looks restored and one that just looks painted over.
