How Much Do Contractors Charge to Build a Deck?

Contractors often charge around $30 to $60 per square foot for a pressure-treated wood deck and $45 to $100+ per square foot for composite or PVC decks, including materials and labour. Labour alone is often $15 to $35 per square foot, and deck builders who charge hourly often bill around $50 to $100 per hour per carpenter.

These are rough ranges; prices vary a lot by region and design.

Cost by material

Example

A 12 × 16 ft (192 sq ft) deck:

• Pressure-treated: roughly $6,000 – $11,500
• Composite: roughly $8,500 – $17,000+

What affects the price

• Size and shape
• Height off the ground (taller decks need more structure)
• Stairs and landings
• Railings (wood, aluminium, cable, glass)
• Multi-level designs
• Removal of an old deck
• Permits and engineering
• Lighting, benches, pergolas
• Site access and soil

Labour

Labour often makes up 40%–60% of the cost. Complex designs and high decks take more time.

How deck builders price jobs

Most quote a total price based on materials, labour hours, permits, equipment and profit, often presented as a price per square foot.

Saving money

Choose a simple rectangle, standard heights, pressure-treated framing with composite boards, and build in the off-season when builders are less busy.
