FAQ — herringbone 20×14
How much does a herringbone 20×14 deck cost in 2026?▾
A herringbone pattern on a 20×14 (280 sqft) deck costs $8,960-$14,280 in pressure-treated, $17,920-$28,560 in mid-tier composite, $26,880-$39,480 in luxury composite/PVC. That's 28% over straight-pattern baseline — about $5,040 extra at mid composite.
What's the waste factor on a herringbone pattern?▾
18% — vs 7% for straight boards. On a 20×14 deck that means ordering 513 linear feet of decking (vs 462 for straight). The extra 51 lf is the difference between order quantity and installed quantity, ending up as offcuts and short pieces.
Does a herringbone pattern affect joist spacing?▾
Yes — primary 16″ o.c. + sub-joist sleepers at 12″ o.c. across. The denser joist spacing supports the pattern visually and structurally. Plan ~30-40% more joists than a straight install would require, plus the matching extra hangers + footings if framing spans need to shorten.
Will my deck warranty cover herringbone?▾
Herringbone requires sleeper/sub-joist framing (a secondary joist layer at 90° to primary). Most composite brands have specialty install instructions; not all warranty-eligible. Trex Signature and TimberTech AZEK explicitly support herringbone.
Is herringbone the right pattern for a 20×14 deck?▾
Best for: Premium builds, decks visible from upper floors, owners wanting a single dramatic design choice. Pairs especially well with two-tone composite. Watch-outs: Doubled framing labor + complex install pattern + 18% waste means total cost is typically 35-45% above straight. Not DIY-friendly without prior carpentry experience. At 280 sqft, herringbone is well-balanced — fits the typical sweet spot for this pattern.
