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.

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