What is the average cost to replace all the deck boards on a 200 square foot deck in Calgary without rebuilding the frame?

Replacing just the deck boards on a 200-square-foot deck in Calgary typically costs $1,600-$3,000 for pressure-treated lumber, $2,400-$4,200 for cedar, or $3,200-$5,600 for composite decking. This assumes the existing frame (joists, beams, posts) is structurally sound and doesn't need repair.

Material costs drive most of the price difference. Pressure-treated decking runs $3-6 per square foot for materials, cedar $6-12 per square foot, and composite $10-18 per square foot. Labour for board replacement is typically $4-8 per square foot, depending on the complexity of cuts around posts, stairs, and railings. Removing old boards, disposing of debris, and installing new decking with proper fasteners takes a skilled crew about 1-2 days for a 200-square-foot deck.

Calgary's climate makes material choice particularly important for replacement projects. If your existing frame is 10+ years old and you're replacing boards due to rot, splitting, or severe weathering, consider upgrading to composite decking even if the original was wood. Composite handles Calgary's chinook freeze-thaw cycles, extreme UV at elevation, and hailstorms better than wood, potentially lasting 25+ years versus 8-15 years for wood in Calgary's harsh conditions. The higher upfront cost often pays for itself by eliminating the need for another replacement in 10-12 years.

Additional costs to factor in include fastener upgrades and disposal fees. Old deck boards often have rusted or stripped screws that need removal with special tools, adding labour time. If you're upgrading to composite, you'll need manufacturer-specified hidden fasteners or colour-matched screws ($0.50-1.00 per square foot extra). Disposal of old pressure-treated lumber requires special handling at Calgary waste facilities, typically adding $200-400 to the project cost.

Timing matters for deck board replacement in Calgary. The work can be done any time the temperature is above freezing, but if you're planning to stain new wood boards, wait until consistent temperatures above 10 degrees Celsius (typically May through September). Pressure-treated lumber should dry for 3-6 months before staining in Calgary's dry climate, so boards installed in spring can be stained in late summer or fall.

When to hire a professional versus DIY: Board replacement is within reach of experienced DIYers if the substructure is sound, but professionals work much faster and handle disposal. A DIY approach saves $800-1,600 in labour but requires tools (circular saw, drill, pry bar), truck rental for materials and disposal, and typically takes a full weekend. Professionals complete the job in 1-2 days with proper tools, disposal connections, and experience working around existing railings and stairs without damage.

Red flags that indicate you need more than just board replacement: If you see sagging areas, bouncy spots when walking, or daylight visible through gaps in the frame, the joists or beams may need repair or replacement. Rotted or damaged framing turns a simple board replacement into a major structural project requiring permits and engineering. Have a contractor inspect the frame condition before committing to board-only replacement.
