If you’re planning a new deck in Aurora, Newmarket, or anywhere else in York Region, pricing is usually the first question — and the honest answer is “it depends on material, size, and design.” Here’s what homeowners in our service area are actually paying in 2026, and what moves the number up or down.
Average Deck Costs by Material
- Pressure-treated wood: the most budget-friendly option, ideal for straightforward rectangular decks.
- Cedar: a step up in appearance and durability, popular for York Region homes with a natural wood aesthetic.
- Composite decking (Trex and similar brands): higher upfront cost, but low-maintenance — no staining or sealing, which matters through Ontario’s freeze-thaw winters.
What Affects Your Quote
- Deck size and height (elevated decks require additional structural work and permits)
- Railing style — glass and aluminum railings cost more than standard wood spindles
- Add-ons like built-in lighting, pergolas, or multi-level designs
- Permit and inspection requirements, which vary by municipality across York Region

Generic online deck calculators don’t account for York Region’s permit process or Ontario Building Code requirements for elevated structures — both of which affect your real cost. A site visit gives you an accurate number instead of a rough estimate.
