Helical Piles vs. Concrete Footings: The Foundation Under Your Deck

What’s under your deck matters as much as what’s on top — especially with Southwestern Ontario’s frost.

Built for the heavy clay soils and deep winter frost common across London, Middlesex County and the surrounding townships.

Option 1 of 2

Helical piles

Our preferred foundation

Lifespan

Upkeep
None
Investment
Upper-mid

Why homeowners choose it

  • Installed in hours — framing can start the same day
  • Minimal digging, no concrete trucks on your lawn
  • Set below the frost line and load-rated as installed

Honest trade-offs

  • Higher cost per post than poured footings
  • Requires specialized equipment

Where it belongs: Composite and PVC decks, additions, and any project where you want zero heaving.

Option 2 of 2

Poured concrete footings

Traditional

Lifespan
30+ yrs
Upkeep
None
Investment
Mid

Why homeowners choose it

  • Proven and widely accepted
  • Lower material cost

Honest trade-offs

  • Excavation, soil piles and curing delays
  • Frost heave risk in clay if not deep or well-formed

Where it belongs: Sites where piles aren’t practical.

Patrick’s field verdict

For premium decks, helical piles are usually worth it: a faster build, a cleaner yard and a foundation that won’t move.
