Wood Decks

A Class Fencing builds custom wood decks across Calgary, Airdrie, Chestermere, Cochrane, Okotoks, High River, Strathmore, Langdon, and the surrounding foothills. From a simple ground-level platform off the back door to a multi-level deck with stairs, built-in benches, privacy screens, and a pergola, we design and build it to suit your yard, your grade, and how you actually want to use the space. Every deck we build is engineered for Alberta — concrete or screw-pile footings set below the frost line, properly flashed ledger connections, and structural hardware rated for our freeze-thaw swings.

Choosing between the two wood options comes down to budget, look, and how much maintenance you want to take on. Pressure-treated spruce is the most affordable and, sealed properly, lasts decades — the workhorse of Calgary decks. Western red cedar is naturally rot-resistant, stays cool underfoot, and takes stain beautifully for a premium look. If you'd rather never stain a deck again, our composite decks (Trex, TimberTech, and similar) and waterproof vinyl decks are the maintenance-free routes — just ask and we'll compare all of them on-site. No upsell, just honest advice.

The part of a deck you don't see is the part that decides whether it lasts. A deck is a structure, not just a surface, and Calgary's frost line makes the foundation critical. A Class Fencing sets footings on concrete piles or helical screw piles driven below the frost line so winter heave can't lift a corner and rack the whole frame. Ledger boards are lag-bolted and flashed to keep water out of the house rim joist, joists are spaced and hung with galvanized or stainless hardware, and every guard and stair is built to the height and spacing the Alberta Building Code requires.

Calgary weather is hard on a wood deck. We get more sunny days than almost any major Canadian city, so UV bleaches and dries out untreated wood fast. Chinook freeze-thaw cycles work footings and fasteners loose if they weren't set right. Heavy spring snow loads sit on the surface, and summer hail tests the boards. A Class Fencing builds for all of it: frost-depth footings, hot-dipped galvanized or stainless structural hardware, proper board gapping for drainage and expansion, and a recommended stain schedule matched to your sun exposure so the wood lasts.

Wood deck cost in Calgary depends on size, height off the ground, material, and features. As a rough guide, a pressure-treated deck typically runs $30 to $45 per square foot installed and cedar $45 to $65 — stairs, multiple levels, railings, privacy screens, pergolas, and skirting all add to the total. A small ground-level platform is at the low end; a raised, multi-level cedar deck with glass or aluminum railing is at the top. (Composite and PVC builds are priced on our composite decks page.) We never quote sight-unseen — the only honest number comes from walking the yard, checking the grade and the house connection, and putting it in writing.

Maintenance on a wood deck is mostly about UV and moisture. Pressure-treated and cedar decks want a clean and a fresh coat of penetrating stain or sealer every 2 to 4 years to fight Alberta UV and moisture — skip it and the boards grey, check, and shorten their lifespan. If that upkeep isn't for you, our composite and vinyl decks need essentially none. We'll set realistic expectations for whichever route you choose so there are no surprises down the road.

Every deck we build comes with a workmanship warranty in writing. The process is the same as any A Class Fencing project: free on-site consultation, written quote within 48 hours, design sign-off, 50% deposit to confirm the build date, balance on completion. Most residential wood decks take 3 to 7 working days depending on size, height, and railing. Call A Class Fencing at (403) 971-4882 or request a free estimate online to get started.
