What new deck construction includes - end to end
A new build with us is a single fixed-price contract that covers everything from the first sketch on the kitchen table to the final inspection sign-off. We handle site assessment, design, structural engineering coordination, the Town of Canmore Development and Building Permits (or Parks Canada for Banff), helical-pile foundations, the framed substructure, decking, railings, stairs, finish carpentry, cleanup, and the inspection itself. You sign one contract and deal with one project lead from start to finish - no chasing piers contractors, engineers, or permit clerks. Every quote includes a side-by-side material comparison so you see exactly what you're choosing and why.
Who this is for
- Bow Valley homeowners replacing an aging deck or building one for the first time
- New construction or major renovations where the deck is part of the package
- Sloped Canmore lots (Three Sisters, Silvertip, Cougar Creek) needing multi-level layouts
- Owners who want a permit-clean, code-stamped deck that holds resale value
- Anyone who's been told their existing deck "can't be saved" and needs a ground-up rebuild
Our process
- Free on-site consultation. We come to you, measure, talk through how you'll use the space, and discuss material trade-offs. 60–90 minutes, no obligation.
- Design and fixed quote. Within 5 business days you receive a CAD plan, material spec sheet, and a single fixed price - no allowances, no surprises.
- Permit submission. We prepare the Town of Canmore application, coordinate the engineer's stamp for any deck over 0.6 m off grade, and submit. Average issuance: 14 business days.
- Helical pile install. Foundations go in within 2 days of permit issuance - torque-verified to bearing capacity, drilled below the 1.2 m frost line.
- Frame and finish. The frame goes up in 3–5 days, decking and railings in another 5–7. Daily site cleanup; we work around your schedule.
- Final inspection and walkthrough. Town inspector signs off, we do a punch-list walkthrough with you, and the lifetime workmanship guarantee begins.
Material options and what they cost installed
| Decking material | Installed price (per sq ft) | Service life in Bow Valley | Maintenance cycle |
|---|---|---|---|
| Pressure-treated SPF | $75–95 | 20–25 years | Stain every 2 years |
| Western Red Cedar | $95–140 | 25–35 years | Oil every 2–3 years |
| Alberta larch | $110–150 | 30–40 years | Oil every 2–3 years |
| Capped composite (Trex Transcend, TimberTech AZEK) | $130–185 | 40+ years | Wash annually |
| Ipe / Cumaru hardwood | $180–240 | 50+ years | Oil every 3–4 years (optional) |
| Duradek vinyl membrane | $140–175 | 25–30 years | Wash annually |
What drives the cost up or down
- Material choice - the single biggest lever. Composite roughly doubles the deck-board cost vs. pressure-treated.
- Height off grade - anything over 0.6 m requires engineered piles, railings, and stairs. Decks 1.8 m+ need a structural engineer's stamp ($800–1,500).
- Multi-level layouts - each transition adds framing, blocking, and stair runs. A two-tier build typically adds 12–18% to a single-level price.
- Railing system - powder-coated aluminum runs $95–130/lf, frameless tempered glass $220–320/lf.
- Site access - Silvertip and Three Sisters slope lots sometimes require crane or chute access for materials, adding $1,500–3,500.
Built for the Bow Valley - the conditions you're actually designing for
Most decking products on the market are spec'd for prairie or coastal conditions. Canmore isn't either. We sit at roughly 1,400 m elevation, which gives us roughly 20% more UV exposure than Calgary at the same latitude (per NRC climate data) - enough to cook untreated softwoods grey inside 18 months. The Town of Canmore design ground snow load is 2.5 kPa (≈52 psf), and the 1-in-50-year event has hit 3.0 kPa in the past decade. Frost penetrates to 1.2 m, which is why every foundation we install is a helical pile driven below that depth - concrete sonotubes set shallow heave every spring and pull the deck out of square within three winters.
We design every new build to the Alberta Building Code (Part 9.23 for residential decks) and the Town of Canmore's Land Use Bylaw setback and height rules. Decks over 0.6 m off grade require a Development Permit plus a Building Permit and a structural engineering stamp; we coordinate all three. Banff projects add a Parks Canada review layer and stricter material/colour guidelines from the Banff townsite Design Guidelines - we know which Trex and TimberTech colourways the Town has pre-approved and steer Banff quotes accordingly. For homes near Cougar Creek or in the Three Sisters debris-flow overlay, we check the Town's hazard maps before siting any pile.
Why choose Canmore Deck Builders for new construction
Zero structural callbacks since 2015
Across 400+ completed builds we've never had a structural callback - no sag, no failed ledgers, no heaved piers. That's a function of helical piles on every build, 12" o.c. joist spacing on every build, and Simpson DTT2Z tension ties on every ledger. We design for the 1-in-50 winter, not the average one.
0 structural callbacks across 400+ Bow Valley builds since 2015 - internal data.One crew, one project lead, start to finish
We run a permanent seven-person crew and take roughly 35–45 builds a year - small enough that the lead carpenter who quotes your job is the same person on site every day and the same person walking you through the punch list. No subcontracted framers, no rotating site managers.
Permit-ready, town-compliant, never failed an inspection
We've submitted every kind of Bow Valley deck permit there is - Town of Canmore, Town of Banff, Parks Canada, MD of Bighorn - with a 100% first-pass approval rate and a 100% final-inspection pass rate. Average Canmore permit turnaround is 14 business days from submission.
