The Best Deck Builders in Ottawa

This guide compares 11 deck builders serving Ottawa. The featured shortlist includes Ottawa Decking Solutions, Hickory Dickory Decks (Ottawa), and Deckify, each a real, currently-operating Ottawa business selected for its local track record and public reviews.

In Ottawa, a deck lives or dies by its footings. Our frost line runs deep, so posts set in shallow holes heave and twist after the first hard winter, which is why the best deck builders dig below 1.5 metres and build framing that shrugs off freeze and thaw. The companies below design and build pressure-treated and composite decks, along with fences, pergolas, and full backyard living spaces, for homes across Kanata, Barrhaven, Orleans, and the core. Each is a real Ottawa company with reviews you can read, so you can weigh design, materials, and warranty before signing.

Buyer guide

Hiring a deck builder in Ottawa

What separates a great deck builder from a cheap quote, and the questions worth asking before you sign.

  • Footings below the frost line

    Ottawa frost heave lifts any deck built on shallow footings. Ask how deep the footings go; they should reach below 1.5 metres, and the builder should confirm the depth in writing.

  • Pressure-treated vs composite

    Pressure-treated wood costs less up front but needs staining every few years. Composite costs more but skips the maintenance and holds colour. Ask for both quotes so you compare lifetime cost, not just the sticker price.

  • Check the permit and drawings

    Most Ottawa decks over a certain height need a building permit and a site plan. A good builder handles the permit and gives you drawings, rather than leaving that on you.

  • Railings and stairs drive the price

    The deck surface is often the cheap part; railings, stairs, and level changes are where cost climbs. Get a quote that itemizes these so you can adjust the design to your budget.

Common questions

Deck Builders in Ottawa, answered

How much does a deck cost in Ottawa?
A quality pressure-treated deck in Ottawa usually runs 45 to 75 dollars per square foot; composite runs higher. Design complexity, railing style, and the number of stairs and levels drive the range.
Do I need a permit to build a deck in Ottawa?
Decks above a set height off the ground, or attached to the house, generally need a City of Ottawa building permit. A reputable builder pulls the permit and provides the drawings; confirm this before work starts.
How deep do deck footings need to be in Ottawa?
Deck footings in Ottawa should extend below the frost line, generally deeper than 1.5 metres, so frost heave cannot lift the structure. Shallow footings are the most common cause of a deck going crooked.
When should I book a deck build for the summer?
Good Ottawa deck builders fill their summer calendars by late winter. Book quotes in February or March to get on the schedule for a spring or early-summer build.
How long does a composite deck last in Ottawa?
A well-built composite deck can last 25 years or more with almost no maintenance, while pressure-treated typically lasts 15 to 20 years with regular staining. Ask about the material and workmanship warranties.
