How a deck is built, from footings to railing
Shown: Raised deck — Step 1 of 5 — Footings
- Footings or helical piles reach below the frost line so the deck can't heave in winter.
- Posts carry the load up from the footings.
- Beams and joists frame the structure under the boards.
- Decking boards and a picture-frame border finish the walking surface.
- A black metal safety railing (guard) goes up last, where required.

Is this deck right for you?
May not suit
- Replacing guards before the existing frame is checked
- Horizontal or cable-look systems assumed compliant without review
- Glass where regular cleaning would be unwelcome
Profiles & details
Styles and options
Black aluminum picket
The most requested colour and a clean, durable choice for most raised decks.
Aluminum + glass
Framed or carefully detailed frameless-style systems preserve garden and ravine views.
Horizontal aluminum
Strong contemporary lines require a climbability and code review.
Wood or composite
Larger profiles can coordinate with the deck surface and privacy details.
Cable-look
A visually light system must be evaluated as a complete approved guard.
Integrated lighting
Post-cap and under-rail light adds safe, quiet illumination after dark.
Balanced guidance
Honest pros & considerations
Advantages
- Can transform an existing deck without replacing sound boards
- Black aluminum works with wood, composite and PVC
- Glass keeps a valuable view open
- Lighting can be planned cleanly inside posts and rails
Considerations
- Hamilton requires a permit to replace or install new guards
- Glass needs more frequent cleaning
- Horizontal elements require climbability review
- Glass panels and supports must suit exposure, including winter conditions

Estimated range for ~192 sq ft$17,180 – $27,240
- Deck surface: $12,480–$18,240
- Stairs: $1,500–$3,000
- Railing: $3,200–$6,000
Raised decks need guards above 600 mm, taller posts and bracing, which push the per-sq-ft rate up. Confirmed on site.
Per-sq-ft rates usually drop as decks get larger; height, stairs, railings and complex shapes push them up.

How we build deck railing decks
A railing is only as dependable as the structure receiving it. We inspect rim boards and blocking, resolve post locations against stairs and picture frames, and use a complete guard system appropriate to the height and exposure.
- 01
Measure deck height and confirm whether guards and a permit are required
- 02
Inspect existing framing and add blocking where the approved system requires it
- 03
Lay out posts around stairs, doors, borders and sightlines
- 04
Install approved posts, rails, panels and fasteners as a complete system
- 05
Keep openings from passing a 100 mm sphere and meet applicable guard heights
- 06
Route post-cap or under-rail lighting before access closes
What's inside a deck, from the ground up
Everything below the boards — footings, posts, beams and joists — is what keeps a deck safe and level for decades; click a layer to see why it matters.
- Native soil: Undisturbed native soil carries the load. Topsoil and fill are not used as bearing.
- Frost line (~1.2 m): Footings must bear below frost depth — about 1.2 m / 4 ft in this region — so freeze–thaw can't heave the deck.
- Pier or helical pile: Concrete piers are poured below frost; helical piles are screwed down to bearing depth with little excavation and can be loaded right away.
- Post + bracket: Posts sit in a bracket on the footing so they stay dry and positively connected.
- Beam: Beams gather joist loads and carry them to the posts.
- Joists + joist tape: Pressure-treated joists; on composite and PVC builds we add joist/beam protection tape to shed water from the tops.
- Ledger + flashing / freestanding: An attached deck needs a properly fastened and flashed ledger. A freestanding design uses its own beam instead of the house.
- Decking, fasteners, gapping: Hidden fasteners and correct gapping on composite/PVC let boards drain and move with temperature.
- Guard: 900 / 1,070 mm + 100 mm sphere: Guards are required above 600 mm. Minimum 900 mm high up to 1.8 m above grade, 1070 mm above that; openings must stop a 100 mm sphere.
- Stair stringers: Stairs must meet Ontario Building Code rise/run and handrail rules; we frame them to code with solid landings.
2. Frost line (~1.2 m)
Footings must bear below frost depth — about 1.2 m / 4 ft in this region — so freeze–thaw can't heave the deck.

Care & maintenance
Check the connections
Inspect posts, rails, stair transitions and gates for movement or loose hardware.
Clean the finish
Wash powder-coated aluminum gently; use compatible glass cleaner on both panel faces.
Review glass and supports
Remove unusual accumulation safely and inspect panels, clamps and structural connections.

Deck Railing FAQ
How high must a deck railing be in Ontario?
Guards are required where the walking surface is more than 600 mm above adjacent grade. Guard height is at least 900 mm where the surface is not more than 1.8 m above grade, and at least 1,070 mm above 1.8 m.
Do I need a permit to replace deck railings in Hamilton?
Yes. The City of Hamilton states that replacement or installation of new guards requires a building permit. Confirm current requirements with the municipality before building.
Is glass or aluminum picket railing better?
Glass preserves views and blocks some wind but needs regular cleaning and has a higher typical range. Pickets are lighter visually, easier to maintain and the most requested black railing style.
How often does glass railing need cleaning?
That depends on rain, pollen, nearby trees and pool spray. Exposed panels usually need more frequent cleaning than pickets.
Can railings be added to an existing deck?
Often, if the framing is sound and can accept the required blocking and connections. We inspect the structure before specifying the guard.
Are horizontal deck railings allowed?
Climbability, openings and the complete approved system must be checked against current code and municipal requirements. Do not assume a cable-look or horizontal detail is compliant.
What size openings are allowed in a deck guard?
Openings must not permit a 100 mm sphere to pass. Stair guards and handrails also need to follow Ontario Building Code requirements.
Can lighting be built into deck railings?
Yes. Post-cap and under-rail lighting are cleanest when wiring routes and service access are planned before the railing is installed.
