FAQ — chevron 24×20
How much does a chevron 24×20 deck cost in 2026?▾
A chevron pattern on a 24×20 (480 sqft) deck costs $15,360-$24,000 in pressure-treated, $30,240-$48,480 in mid-tier composite, $45,600-$66,720 in luxury composite/PVC. That's 26% over straight-pattern baseline — about $8,160 extra at mid composite.
What's the waste factor on a chevron pattern?▾
16% — vs 7% for straight boards. On a 24×20 deck that means ordering 864 linear feet of decking (vs 792 for straight). The extra 72 lf is the difference between order quantity and installed quantity, ending up as offcuts and short pieces.
Does a chevron pattern affect joist spacing?▾
Yes — 12″ o.c. + center sleeper-beam to hold the v joint. The denser joist spacing supports the pattern visually and structurally. Plan ~20-25% 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 chevron?▾
Chevron is a specialty pattern — requires precision miter cuts on every board pair. Most brands list it under 'custom installation' (warranty negotiated case-by-case). AZEK and Trex Signature are most permissive.
Is chevron the right pattern for a 24×20 deck?▾
Best for: Long decks (3:1+ aspect ratio), decks pointing at a focal feature (pool, view, garden centerpiece), modern architecture. Watch-outs: The center V-joint is a wear point and water-collection seam. Plan for re-flashing at year 5-7 even on capped composite. At 480 sqft, chevron is natural — the larger field gives the pattern room to breathe.
