- Ledger Attachment — The Connection That Fails When Decks Collapse
The deck does not break. The connection to the house lets go, all at once, usually with people standing on it.
- Post to Beam — Wood on Wood, Never Fasteners Alone
Bolts through the side of a post look solid and carry the load in shear on the fastener. The code wants the weight sitting on wood.
- Deck Cost by State — Priced From BLS Carpenter Pay
Deck quotes vary more within a town than between states, and this table shows why: carpenter pay ranges 45% across the country but only lands on 55% of the bill.
- Deck Cost by Size — 8×10 to 20×24, and the Two Things That Beat Square Footage
Deck cost per square foot falls as the deck grows, then height undoes it. A tall 12×16 can cost more than a ground-level 16×20.
- Deck Stair Railing Cost by Material, and the Code That Sets the Design
Railing is priced per linear foot and specified by code. Most of the cost difference between quotes is which of the two rules the builder read.
- Deck Board Gap: Why Wet Lumber and Composite Need Opposite Numbers
There is no single correct gap. There is a correct gap for a board that is going to shrink and a different one for a board that is going to grow.
- Deck Stair Rise and Run: The Limits, and the 3/8 Inch That Fails Inspections
Stairs fail inspection more often for being uneven than for being too steep, and the tolerance is three eighths of an inch across the whole flight.
- Cost to Replace Deck Boards Only: When Resurfacing Beats Rebuilding
Resurfacing saves roughly half the cost of a rebuild, provided the frame underneath has more life left than the boards you are about to screw to it.
- Deck Beam Span Table: Why the Span Depends on the Joists, Not the Deck
A beam span table has two inputs, and the one people forget is the joist span the beam is carrying. Read it with one input and the answer is wrong by feet.
- Deck Footing Size by Soil Bearing: Tributary Area, Load, and the Diameter It Gives
Footing size is one division: the load a post carries, divided by what the soil under it can hold. Both numbers are published, and neither is the one people guess.
- Deck Framing Lumber Cost: A Line-by-Line Take-Off for a 12 × 16 Deck
The frame is a third of a deck's cost and the part nobody itemises. Here it is, line by line, for a deck you can scale from.
- Deck Permit Cost and the Thresholds That Trigger One
The permit is rarely the expensive part. The unpermitted deck discovered during a sale is, and that bill arrives at the worst possible moment.
- Deck Post Size by Height: When 4×4 Stops Being Allowed
The 8 ft line is where 4×4 stops. Above it the question is not only size but bracing, and the connection at each end matters more than the post between them.
