The railing is the detail that makes or breaks the look of a finished deck. Most homeowners pick it last, after the structure and decking material decisions are already made. That’s a mistake — the railing affects your budget, your view, your sightlines from inside the house, and your maintenance schedule for the next 20 years.
Why the Railing Decision Matters More Than You Think
A composite deck with the wrong railing looks ordinary. The same deck with the right railing looks like a design feature. Beyond aesthetics, BC building code requirements for railing height, post spacing, and infill gaps are non-negotiable on any deck over 600 mm from grade. Before any railing discussion, read our guide on deck permits in Vancouver — permits cover the structure and the railing.
Glass Railings
Glass railings are the most-requested option we install in Tsawwassen — and for good reason. On properties with ocean views, mountain views, or even a well-landscaped backyard, glass does what no other material can: it disappears.
Best for: Properties with views worth preserving, modern or contemporary architecture, homeowners who want the deck to feel like an extension of the interior.
The honest drawbacks: Glass shows everything — salt spray, dust, fingerprints. In Tsawwassen, oceanside properties will clean glass panels more often than anyone anticipates. Glass is also the most expensive system, and a cracked panel needs full replacement.
For a deeper look at glass vs. aluminum specifically, see our post on aluminum vs. glass railings.
Aluminum Railings
Aluminum is the smart workhorse. It’s the most widely installed railing system we sell, and it earns that position: it performs without demanding anything from you.
Why we like it: 50-year lifespan with no repainting required (powder coat holds colour). No rust — ever. In BC’s coastal climate this is meaningful: any ferrous metal railing will eventually show rust staining on the deck surface. Aluminum doesn’t. Available in dozens of colours, BC seismic code compliant on standard residential installs.
Best for: Virtually every residential application that doesn’t require glass, properties near salt water, and budget-conscious builds that still want a premium finish.
Cable Railings
Cable railing has a specific aesthetic: industrial-coastal-contemporary. If your home is a modern box, a renovated mid-century, or has strong horizontal lines in the architecture, cable railing can look exceptional. On a traditional craftsman home, it usually looks out of place.
The honest drawbacks: Horizontal cables create a ladder effect — under BC building code, horizontal cable spacing must meet the sphere test (no gap greater than 100 mm), but the same horizontal orientation is not recommended where young children are present because it’s climbable. Cables also require periodic re-tensioning.
Our Recommendation by Situation
| Situation | Railing |
|---|---|
| Ocean or mountain view property | Glass (frameless if budget allows) |
| Standard backyard, family home | Aluminum picket |
| Modern/contemporary architecture | Cable or glass |
| Budget-conscious build | Aluminum |
| Property near salt water | Aluminum or glass — avoid ferrous metals |

Railing and Your Total Deck Budget
Railing cost is the line item that most often surprises homeowners mid-quote. For a full picture of what a complete deck costs in Metro Vancouver, see our deck cost guide.
We install all three systems across Delta, Tsawwassen, and Metro Vancouver.
We document every railing install on Instagram and Facebook — real projects, real materials, real properties in your area.
