Deck Staining & Refinishing

Deck staining and refinishing is not optional in Calgary — it is essential maintenance that directly determines how long your wood deck will last. Calgary's intense UV radiation at 1,045 metres elevation breaks down wood fibres and finishes roughly 30% faster than at sea level, meaning a stain that lasts 3-4 years in Vancouver may need reapplication after just 2 years in Calgary.

The city's chinook freeze-thaw cycles compound the damage: moisture penetrates unstained wood, freezes and expands in the grain, then thaws during a chinook, creating cracks and splits that deepen with every cycle. A properly applied penetrating stain with UV inhibitors is the single best investment you can make to extend your Calgary deck's lifespan.

Professional deck refinishing in Calgary involves stripping the old finish down to bare wood using a deck cleaner and brightener, sanding any rough or splintered areas, and applying a fresh coat of high-quality penetrating stain that soaks into the wood grain rather than sitting on the surface like paint. Semi-transparent oil-based stains are the most popular choice in Calgary because they allow the wood grain to show through while providing excellent UV and moisture protection.

The ideal staining window in Calgary is late spring through early fall when temperatures stay between 10-30 degrees Celsius and there is no rain in the 24-48 hour forecast — which can be tricky to time around Calgary's unpredictable summer weather.
