Factors That Affect Deck Pricing

Site Access and Conditions

Difficult access, sloping sites, or poor soil may increase labour and foundation costs.

Timber Choice

Hardwoods and composites are more expensive but last longer and require less upkeep.

Deck Height

Higher decks need deeper footings and railings, which add material and labour costs.

Design Complexity

Curved edges, inlays, levels, or features like pergolas will increase overall cost.

Budget-Saving Tips

Keep It Simple

A straightforward rectangular design without elevation changes or built-in extras keeps labour and material costs lower.

Use Treated Pine for the Substructure

Even with hardwood decking boards, using pine joists and bearers reduces costs without compromising durability.

Stage Your Project

Start with the core deck area and add stairs, balustrades, or seating later as budget allows.
