Calgary deck builders

Deck Builders in Calgary

We design, permit and build decks for Calgary homes: composite, cedar, pressure treated and waterproof vinyl membrane, all on footings that go below the frost line. You get one price in writing before we start, and the same team from the first measure to the final inspection.

  • Permits pulled for you
  • Frost-depth footings
  • 5-year workmanship warranty

What you're actually paying for

The boards are the part everyone looks at. What decides whether a deck is still flat and solid in fifteen years is underneath: the footings, the ledger connection to the house, and how the frame handles Calgary's freeze-thaw swings.

  • Footings below the frost line. Shallow footings heave when the ground freezes, and a heaved deck pulls away from the house.
  • We handle the permit. Drawings, site plan, the application and the inspections. You don't chase the City; we do.
  • One written price. We quote the whole job up front, including stairs, railings and skirting, so the invoice matches the quote.
  • Five-year workmanship warranty, in writing, on top of the manufacturer's warranty on the materials.

How a deck gets built properly here

Calgary is hard on outdoor structures. The ground freezes deep, chinooks thaw it mid-winter, and then it freezes again. A deck that isn't built for that moves. These are the steps we don't skip.

  1. Measure and designWe look at the grade, the doors, where the sun sits in the afternoon and how you'll get on and off the deck, then draw it up.
  2. PermitMost decks in Calgary need a building permit, and some need a development permit too. We prepare the drawings and site plan and apply for you.
  3. FootingsFootings go below the frost line so the deck doesn't lift and settle with the seasons.
  4. Ledger and frameWhere the deck attaches to the house is flashed so water can't sit against the rim board. Joist spacing is matched to the decking you choose.
  5. Decking, stairs, railingsBoards, fasteners, stair stringers, guards and skirting, finished to the spec in your quote.
  6. InspectionThe City inspects before the job is closed, and we walk it with you.

Shade and privacy

A deck gets used a lot more when there's somewhere to get out of the sun. We build pergolas and cabanas on new decks, on existing ones, and free-standing in the yard.

Replacing an old deck

If the deck you have is tired, the first question is whether the frame is still sound. When the posts, beams and ledger are solid, new boards and railings over the existing structure can be the right call. When they aren't, it's a full rebuild, and we'll tell you which one you're looking at.

Our guide to when to replace your deck goes through the signs.

Common questions

Do I need a permit for my deck?

In Calgary, yes if the deck is covered, or if its surface is more than 0.6 m (2 ft) above grade at any point. A development permit can also apply depending on setbacks. We handle both. The full rules are in our Calgary deck permit guide.

Is a quote free?

Yes. We come out, measure and give you a written price for the whole job.

Can you add a pergola or cabana at the same time?

Yes, and it's usually easier to plan the footings for a pergola or cabana with the deck than to add them later. A roof over a deck triggers a permit on its own, so it's worth deciding early.

Is there a warranty?

Our workmanship is covered for five years, in writing. Materials carry their own manufacturer warranties on top of that.
