Why natural hardwood still wins for some homes
When you want real wood — wood that ages, wood with grain and depth no composite can fake — premium tropical hardwoods are the answer. Red Balau, Ipe, and Cumaru run 3–4 times harder than cedar, naturally resist insects and rot, and carry a 25–40 year lifespan when oiled once every 2–3 years.
We hand-pick every board. We predrill and countersink every fastener. We use marine-grade stainless on everything — the same screws used on dockside construction. Two coats of Penofin or Messmer's UV oil go on the day we finish. The deck is photograph-ready the day we hand over the keys.
Cedar — the traditional Long Island hardwood
Western Red Cedar is the old-school Long Island deck. Naturally insect- and rot-resistant, clear grade only, with that recognizable red-amber tone. Left unfinished it weathers to a silver patina in 18–24 months — some homeowners love it, others oil it annually to keep the color.
Cedar costs less than mahogany and frames beautifully for pergolas, railings, and built-ins that match a cedar deck. We use kiln-dried clear cedar only — no knots, no sapwood, no greenwood twist.

Long Island mahogany & cedar reviews
They showed up when they said, built what they promised, and handled every permit themselves. I didn't touch a town hall form.
The crew was clean, Vinny walked the job every day, and the final walk-through caught things I wouldn't have noticed.
Third project with Long Island Deck Co. in six years. They deliver every time.
Common questions
If you want real wood with real grain, yes. If you want zero maintenance, composite. Mahogany needs re-oiling every 2–3 years — about 6 hours of work for a 300 sq ft deck. In return you get a surface that looks richer and more natural than any composite. It's a style call.
Yes — Ipe (also called Brazilian Walnut) is one of the densest commercial woods. It runs ~3,600 on the Janka hardness scale (2–3x cedar). On Long Island we've seen properly-built Ipe decks still structurally sound at 30+ years. The caveat: it's harder to work with and slower to install, so labor runs higher.
If you want to keep the red-amber color, once a year. If you're happy letting it weather to silver, never — cedar is naturally rot-resistant and will still last 20–30 years structurally.
Yes. Permit requirements don't depend on material — they depend on height above grade and whether the deck is attached to the house. We handle every permit.
