Still the best value on the market

Pressure-treated lumber has built more American decks than every other material combined. On Long Island, a well-framed PT deck gives you 15–25 years of structural life at roughly half the cost of composite. The tradeoff: annual or biennial cleaning and sealing to prevent graying and splitting.

Not every backyard needs a $30,000 composite deck. If you're planning to sell in 5–8 years, or if the deck is a secondary surface off a basement walkout, pressure-treated is the right call. We build PT decks with the same framing standards as our composite work — code-plus connector hardware, frost-depth footings, and flashing at every board contact.

What customers say

Long Island pressure-treated reviews

They showed up when they said, built what they promised, and handled every permit themselves. I didn't touch a town hall form.

Paul D.Massapequa · Pressure-Treated

The crew was clean, Vinny walked the job every day, and the final walk-through caught things I wouldn't have noticed.

Angela R.Wantagh · Pressure-Treated

Third project with Long Island Deck Co. in six years. They deliver every time.

Pressure-Treated FAQ

Common questions

With annual cleaning and sealing every 2–3 years, 20–25 years is realistic. Without maintenance, expect 12–15 before major rebuild work.

No. Modern ACQ (alkaline copper quaternary) treatment has been the standard since 2004 — it's safe for residential use including deck surfaces kids and pets use daily.

Yes, but wait 6 months after install for the boards to fully dry. We recommend a penetrating semi-transparent stain — opaque paint traps moisture and peels.
