FAQ — chevron 30×20
How much does a chevron 30×20 deck cost in 2026?▾
A chevron pattern on a 30×20 (600 sqft) deck costs $19,200-$30,000 in pressure-treated, $37,800-$60,600 in mid-tier composite, $57,000-$83,400 in luxury composite/PVC. That's 26% over straight-pattern baseline — about $10,200 extra at mid composite.
What's the waste factor on a chevron pattern?▾
16% — vs 7% for straight boards. On a 30×20 deck that means ordering 1080 linear feet of decking (vs 990 for straight). The extra 90 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 30×20 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 600 sqft, chevron is natural — the larger field gives the pattern room to breathe.
