Common Questions

Yes, a permit is required in Hamilton for any deck attached to a house or any deck more than 24 inches (600 mm) above the ground. The minimum permit fee for 2026 is $291, though total costs including zoning reviews often reach $800.

Pressure-treated wood decks average $45-$65 per sq ft installed, while composite decks (like Trex or TimberTech) range from $85-$115 per sq ft. A standard 200 sq ft wood deck costs roughly $10,000 compared to $19,000 for composite.

In Hamilton, professional railing installation costs between $50 and $95 per linear foot depending on material (aluminum vs. glass). Stairs are typically billed at $175 to $350 per step, which can add $1,500+ to an elevated deck project.

Labor rates for 2026 range from $25 to $55 per square foot. Complex multi-level designs or decks requiring deep concrete footings to clear the local frost line sit at the higher end of this range.
