Backyard Deck Build
This is the whole project as estimators actually run it — each step feeds the next, and the right tool is embedded exactly where you need it.
Step 1: Footings below frost
Piers sized and dug below local frost line. fence post depth estimate tool.
Step 2: Concrete piers
Sonotube volume per pier × count. concrete column estimate tool.
Step 3: Frame the joists
Species span tables; 16 in OC standard. figure your joist numbers.
Step 4: Deck boards & fasteners
Rows = width ÷ (board + gap); +10% cuts. run the numbers with our deck tool.
Step 5: Stairs
Risers ≤ 7¾ in, treads ≥ 10 in, stringer by Pythagoras. stair estimate tool.
Step 6: Budget check
Material grade drives $15–$60/sq ft installed. deck cost calculator.
