Construction comparison
Concrete Footing vs Deck Blocks: Foundation Choice
Compare concrete footings and deck blocks for decks, sheds, frost, code, load, speed, cost, and long-term movement.
Verdict
Quick answer
Use concrete footings for permanent, code-sensitive, frost-aware, and higher-load structures. Use deck blocks only for light, temporary, or low-risk projects where local rules allow them.
Ratings
Strength, durability, moisture, and workability.

Pros and cons
Tradeoffs by option.
Concrete footing pros
- Best fit for decks, sheds, posts, frost zones, inspections, and permanent loads
- Load: Higher and more permanent
- Frost: Can reach frost depth
- Code: More likely accepted
- Clear choice when the project is designed around Concrete footing.
Concrete footing cons
- Can be the wrong choice when the job is closer to temporary platforms, light sheds, low decks, and non-permit utility bases.
- Requires checking real stock, tool setup, installation conditions, and finish expectations.
- May cost more in rework if chosen only because Concrete footing is familiar.
- Compare against Deck blocks with the actual measurements before buying.

Applications
Common applications
Use Concrete footing for
decks, sheds, posts, frost zones, inspections, and permanent loads.
Use Deck blocks for
temporary platforms, light sheds, low decks, and non-permit utility bases.
Maintenance
Maintenance and long-term fit
Do not compare only sticker price or the first setup step. Compare the whole workflow: measuring, buying, cutting, installing, finishing, revising, maintaining, and repairing the result. A cheaper or faster option can still lose if it creates more waste, harder cuts, weaker fastening, worse appearance, or more rework after the first mistake.
Plan the work after choosing
Once you choose between Concrete footing and Deck blocks, run your own numbers. WoodCutTool calculators and apps help turn the comparison into a cut list, sheet count, material estimate, or project record before you buy or cut.
