Calgary Deck Railings — Aluminum and Glass, Built for Wind and Chinook
Arch & Bow builds aluminum and glass deck railings for Calgary and Airdrie homeowners, sized to the exact Alberta Building Code height and spacing rules for your deck. Every design is rendered in 3D and approved by you before installation, and if your project needs a permit, we handle it end to end.

We design and install aluminum and glass railings for decks, balconies, and stairs — built to the height and baluster-spacing rules your specific deck triggers, not a generic default. Every design is rendered in 3D and approved by you before installation starts.
Work is carried out by trade subcontractors with years of hands-on experience in the field — the crews' experience, not a company track record, since Arch & Bow is new to direct residential work as of this pivot.
Is deck railing height 36 or 42 inches in Calgary?
It depends on how high the deck is: the railing must be at least 36 inches (0.9m) if the deck surface is under 1.8m above grade, and at least 42 inches (1.07m) at 1.8m or higher. This threshold is the same one that applies to decks generally — see our Calgary deck permit guide for the full permit context.
Verified against calgary.ca, October 2026, which cites Division B, 9.8.8.3 of the 2019 National Building Code – Alberta Edition. Alberta moved to the 2023 edition on May 1, 2024, which carries the same heights per a 2023-edition municipal deck checklist.
What's the baluster spacing rule?
The maximum gap between railing balusters is 100mm (4") — small enough that a child's head can't pass through.
Verified against calgary.ca, October 2026 — citing Division B, 9.8.8.5; the 100mm limit is unchanged in the 2023 edition.
| Deck surface height | Minimum railing height | Max baluster gap |
|---|---|---|
| Under 1.8m | 0.9m (3'-0") | 100mm (4") |
| 1.8m or higher | 1.07m (3'-6") | 100mm (4") |
How much do deck railings cost in Calgary?
Aluminum runs about $60 to $120 per linear foot installed in Calgary and glass about $100 to $150. A typical 200 sq. ft. deck needs 40 to 50 linear feet, so aluminum usually lands around $2,400 to $6,000 and glass around $4,000 to $7,500.
Aluminum and glass per-foot ranges per Calgary Deck Contractors (March 2026) and Calgary Construction Network (June 2026), both checked October 2026; linear footage per HomeStars. The totals are our arithmetic on those figures.
Pressure-treated wood is the lowest-cost railing, at about $35 to $50 per linear foot in Calgary per Calgary Construction Network, but it's also the only one of the three that needs periodic staining.
Why aluminum or glass for a Calgary deck railing?
Aluminum and glass don't rot, crack, or need periodic staining the way wood railings do, and both hold up to Calgary's chinook cycles — the repeated freeze-thaw swings that stress joints and fasteners on materials that expand and contract at different rates. Aluminum handles wind loading on solid or semi-solid panels with a lighter structure than wood; glass keeps sightlines open on a deck where the view is the reason you built it. For the full cost breakdown and the one trade-off worth knowing before you choose, see our glass vs. aluminum railing guide.
Do stairs need railings too?
Yes — the same height and baluster-spacing rules that apply to a deck surface apply to deck and exterior stairs, and a handrail is required on any stair with more than 3 risers. We build stair and deck railings as one continuous system rather than two separate quotes, so the transition at the top and bottom of the stairs is designed once, not patched together. For the full handrail height, continuity, and climbability rules, see our deck & exterior stair railing guide.
How does the 3D render and permit process work?
Height, material, baluster spacing, and how the railing meets the stairs all get checked against code and modeled in a 3D render before installation — the details that are easiest to get wrong are the ones we visualize first. If your deck or the railing itself needs a permit, the drawings, submission, and inspection booking are ours to manage.
Why choose Arch & Bow over another Calgary railing company?
Most Calgary railing companies lead with years in business or a review count — we can't say either yet, because this is a new direct-to-homeowner offering as of late 2026. What we can say specifically: every railing gets a 3D render you approve before installation, built to the exact code figures your deck triggers, not a one-size default.
If a track record matters more to you than a spec-first process, we'd rather you know that upfront than oversell it.
Do you build railings outside Calgary?
We build railings across the region, and the guard and handrail figures change by municipality — see our Airdrie, Okotoks, or Cochrane railing pages for what applies specifically where you live.
