How much do Sonotube concrete forms cost for deck footings in New Brunswick?

Sonotube concrete forms for deck footings in New Brunswick typically cost $15-35 per tube, depending on diameter and where you shop. The most common sizes for residential deck footings are 10" and 12" diameter tubes.

Sonotube Pricing by Size:

• 8" diameter: $12-20 per tube (suitable for small decks, light loads)


• 10" diameter: $15-25 per tube (most common for residential decks)


• 12" diameter: $20-35 per tube (heavy decks, multi-level structures)

You'll find Sonotubes at Home Depot, Kent Building Supplies, and local lumber yards throughout New Brunswick. Kent often has competitive pricing and better availability in smaller communities like Bathurst, Miramichi, or Sussex.

What You'll Actually Need for NB Deck Footings:
Beyond just the Sonotube, budget for the complete footing system. Each footing requires:

• Sonotube form: $15-35


• Concrete (1-2 bags per footing): $8-16


• Rebar (2-3 pieces): $5-10


• Post anchor or bracket: $15-30


• Total per footing: $45-90

Critical NB Requirements:
Your Sonotubes must extend below frost depth — that's 1.2 metres (4 feet) in Moncton/Saint John/Fredericton areas, and 1.5 metres (5 feet) in northern regions like Bathurst or Edmundston. This means you'll need 5-6 foot Sonotubes for most NB locations, not the shorter ones you might see advertised.

Money-Saving Tips:
Call ahead to check availability — some stores offer contractor discounts for multiple tubes. If you're doing 6+ footings, ask about bulk pricing. Also, consider having concrete delivered rather than mixing bags if you need more than 10-12 footings.

When to Hire a Professional:
While buying Sonotubes is straightforward, digging to frost depth in NB's rocky soil and ensuring proper drainage can be challenging. Many homeowners underestimate the physical demands of digging 4-5 feet deep in Maritime clay and rock. If your deck requires a building permit (attached to house or over 24" high), you'll need professional installation anyway to pass inspection.
