Limits
- Planning prices from this calculator, not a Trex price list or a contractor bid. Local board prices move.
- The total covers deck boards and a flat labor rate. Railings, stairs, footings, flashing, and clips are separate.
- A 25-year composite deck still needs the framing underneath sized for the span and the local code.
