What Affects Deck Building Cost in Milton?

Deck material

Pressure-treated pine is the most affordable ($4–$7/sqft material). Composite decking (Trex, TimberTech) costs $12–$22/sqft material but lasts 25+ years with minimal maintenance.

Size and complexity

Labour is typically $12–$25/sqft for a basic deck. Multi-level decks, stairs, and built-in seating increase costs significantly.

Footing type

In Milton's frost climate, decks require concrete footings below the frost line (1.2m depth). Helical piers ($300–$600 each) are a popular alternative.

Permit requirements

Milton requires a building permit for decks higher than 600mm (about 2 feet) from grade. Expect $350–$800 for the permit.
