Common Questions

Yes, a permit is required if the deck is attached to the house, higher than 24 inches (60 cm) above grade, or has a total area greater than 10 square metres (approx. 108 sq ft).

As of 2026, the City of Windsor charges $11.00 per square metre for a deck without a roof (minimum $275.00), plus a $70.00 Zoning Certificate fee. A typical 200 sq ft deck permit costs approximately $345.00.

While individual carpenter wages average $27-$30 per hour, contractors typically bill between $50 and $95 per hour to cover overhead, insurance, and WSIB requirements.

Due to Windsor's high humidity and freeze-thaw cycles, composite decking (e.g., Trex or TimberTech) is highly recommended. While it costs $65-$95 per sq ft installed compared to $45-$65 for pressure-treated wood, it resists the warping and rot common in the region.
