Common Questions

In Hamilton, a building permit for a deck typically costs between $150 and $500, depending on the deck's height, size, and whether it is structurally attached to your home.

You can expect to pay $30 to $50 per square foot for a standard pressure-treated wood deck. High-end composite or PVC decking ranges from $60 to $95 per square foot fully installed.

A standard 200 sq ft pressure-treated deck averages around $7,000 to $10,000. Upgrading to composite materials with premium features like glass railings can push the total cost to $15,000 to $20,000 or more.

According to Ontario building codes and local Hamilton guidelines, any deck that is over 24 inches (2 feet) above grade requires a secure railing system for safety.
