Strip, Brighten, Stain & Seal
Deck Staining Long Island
Deck staining and sealing for Long Island decks — cedar, pressure-treated, IPE, mahogany. We strip old finishes properly, brighten the wood, and apply a penetrating or solid stain that actually lasts through a New York winter.
Deck Staining done right, from prep to final coat
Deck finishing is misunderstood. Most homeowners slap on another coat of stain over the old, peeling layer and call it a day — then wonder why it fails again in 8 months. We take decks back to bare wood when needed (chemical stripper + pressure wash), brighten with oxalic acid wood brightener, let it dry 24–48 hours, then apply the right product for the wood species: Penofin penetrating oil for IPE and cedar, Benjamin Moore Arborcoat semi-transparent for pressure-treated, or solid-color stain when the wood is past its prime. Transparent stains show the grain but need reapplication every 2 years. Solid stains last 4–6 years but cover the texture. We tell you which makes sense for your deck based on age, species, and past finishes.
Our process — step by step
- 1
Assess
Walk the deck, identify species, note failed boards, recommend strip vs clean-only, and pick the right stain type for your goals.
- 2
Strip & Brighten
Chemical strip failed finish (if needed), pressure-wash at the right PSI for the species, brighten with oxalic acid. 24–48 hour dry.
- 3
Repair
Loose boards re-screwed, popped nails set, splinters sanded, rotted boards replaced and primed.
- 4
Stain & Seal
Penetrating oil or solid stain applied in thin coats, back-brushed for even absorption. Railings and spindles detailed by hand.

Why homeowners pick us for this job
Strip, Don't Slap On
We don't paint over failed stain. That's how you get a deck that peels in a year. We take it to bare wood when the old finish is failing.
Species-Matched Product
IPE needs Penofin. Cedar wants breathable oil. Pressure-treated takes Arborcoat well. We don't one-size-fits-all your deck.
Back-Brushed
Stain that sits on the surface instead of being back-brushed into the grain will fail early. We back-brush every board, every time.

Common Questions
Deck Staining FAQs
How often do I need to re-stain my deck?+
Depends on stain type and sun exposure. Transparent/penetrating stains: every 2 years. Semi-transparent: 3–4 years. Solid color stains: 4–6 years. South-facing decks re-coat on the shorter end of each range.
Can you stain a deck that's been painted?+
Yes, but it's a bigger job. Painted decks need full stripping to bare wood before stain can penetrate. Sometimes a solid-color stain over existing paint is the right answer — we walk you through the tradeoffs.
What's the best time to stain a deck on Long Island?+
Late May to mid-June, and mid-September to mid-October — the same exterior painting windows. Stain needs 48 dry hours on each side of application, and you don't want morning dew undoing the first coat.
Do you stain pressure-treated wood?+
Yes. New pressure-treated needs 6–12 months to dry out before first stain — we can confirm with a moisture meter. Older PT deck boards take stain beautifully with Benjamin Moore Arborcoat or Sherwin-Williams SuperDeck.
