How Much Does a Deck Cost in Ottawa? 2026 Price Guide

Deck cost in Ottawa is driven by four things: square footage, decking material, height off the ground, and railing style. Two decks of the same size can differ by thousands of dollars once those variables change, which is why an on-site quote from a local deck builder is always more accurate than an online calculator.

Typical Ottawa deck price ranges

• Pressure-treated deck: the lowest entry point, best for simple ground-level builds in Nepean or Riverside South.
• Cedar deck: a mid-range option with better looks and natural rot resistance.
• Composite or PVC deck: the highest upfront cost, offset by very low maintenance over 25+ years.
• Elevated or multi-level decks: add framing, stairs, footings and guard railing, which raises the total materially.

What raises the price

• Height above 24 inches, which triggers code-required guards and deeper footings.
• Aluminum, glass or cable railing instead of wood pickets.
• Stairs, landings, benches, planters, privacy walls and skirting.
• Difficult access, sloped yards, or removal and disposal of an old deck.
• Permit and inspection requirements in the City of Ottawa.

How to compare deck quotes fairly

Ask every deck contractor for the same specifics: footing depth and diameter, joist spacing, beam sizing, fastener type, railing system, and whether permit costs and old-deck removal are included. A cheap quote is often cheap because one of those items was left out.
