Every deck consultation on the South Shore reaches the same fork: wood or composite? We build both, so this isn't a sales pitch — it's the honest comparison, specific to what South Shore weather does to decks.
The Real Cost Comparison
Pressure-treated wood wins the day-one price — typically 30–40% less than mid-grade composite on materials. Then the meter starts running. A wood deck near the coast needs washing and re-staining every 1–2 years (more often than inland — salt and sun accelerate everything), plus periodic board and fastener replacement. Over 15 years, maintenance typically erases the entire upfront savings. Composite needs soap and water.
What South Shore Conditions Do to Each
To wood: UV grays it within a season or two; salt air corrodes standard fasteners into streaks; freeze-thaw cycles open checks and splinters; coastal humidity feeds mildew on shaded boards.
To quality composite: color holds for decades (modern capped boards bear little resemblance to 2005-era composite); nothing rots, splinters, or needs stain; stainless fasteners eliminate corrosion streaking. The honest cons: it runs warmer underfoot in full sun (lighter colors help), and it costs more on day one.
Where Wood Still Wins
Budget-constrained projects, structures that will be rebuilt within a decade anyway, and homeowners who genuinely love the ritual and look of real stained wood. There's no wrong answer — just an honest fit.
The Frame Matters More Than the Surface
Whichever surface you choose, the substructure is wood either way — and it's where decks actually fail. We build frames with proper flashing, joist tape, correct spacing for the specific decking, and stainless hardware near the coast. A composite deck on a shortcut frame is a 30-year surface on a 12-year structure.
