How much does a deck cost in London, Ontario?

A deck in London, ON costs $30–$75 per square foot. A standard 200 sq ft pressure-treated wood deck runs $6,000–$10,000. Composite decking (Trex, TimberTech) costs $45–$75/sq ft, so the same deck would be $9,000–$15,000 including railings and stairs.

Do I need a permit to build a deck in London, ON?

Yes. In London, Ontario, any deck over 24 inches above grade or over 108 sq ft requires a building permit. The permit ensures proper footing depth (4 feet below grade for frost), structural capacity, and railing height (42 inches minimum). Sodify handles all permits.

What deck material is best for Ontario weather?

Composite decking is best for Ontario weather — it won't rot, warp, splinter, or need staining. It handles freeze-thaw cycles without damage. Pressure-treated wood is 40% cheaper but requires annual maintenance (staining/sealing) and lasts 15–20 years vs 30+ for composite.
