Deck Builders Near Me in Kings Park, NY? Build Your Own Deck With an A-DIY Kit

North Shore deck contractors serve Kings Park, and they are the right choice for decks attached to the house or built over a slope. Ask for a Suffolk County home improvement license, proof of insurance and recent Town of Smithtown permits. For a freestanding deck on level ground, an A-DIY kit is a simpler path: it arrives engineered and labeled, and a drill is the only tool you need.

Contractor quotes vary with size, design, railings and the permit process, so collect several in writing. Every A-DIY kit has a published price, starting at $3,699 for a 6x12 pressure-treated kit and topping out at $12,799 for a 16x28 composite kit. Because you supply the labor, building it yourself typically costs 30–50% less than hiring a contractor.

With A-DIY, a 12x12 deck kit is $4,899 in pressure-treated wood or $5,700 in composite. A 12x16 composite kit is $6,600; the closest wood size is 12x18 at $5,969. A 16x20 kit is $7,600 in wood or $10,199 in composite. Framing, decking, footings and hardware are included.

Plan on checking. Kings Park is a hamlet in the Town of Smithtown, so the Town of Smithtown Building Department reviews decks here. Town code lists decks in its building permit fee schedule and exempts only ordinary, non-structural repairs, so contact the Building Department about any new deck. Homes in nearby incorporated villages, such as Nissequogue, follow their village’s rules instead.

Not automatically. The NYS Residential Code generally exempts freestanding decks of 200 sq ft or less, no more than 30 inches above grade and not serving a required exit door, but the Town of Smithtown’s code does not list decks among its permit exemptions. Call the Building Department with your planned size and height before ordering. A-DIY kits assemble 15–17 inches off the ground.

Many customers use their A-DIY decks for hot tubs and saunas. Applicable configurations are engineered to hold up to 15,000 lbs when properly assembled and supported, but tub weight, placement and wiring vary, so talk to a deck specialist before you order and check local electrical and permit rules.

Attached or permitted decks generally need footings below the frost line, at the depth the Town of Smithtown Building Department specifies. A floating deck is supported differently: an A-DIY kit rests on included Tuff Block footings over firm, compacted, level soil, with no concrete piers to dig. Build it on the flattest part of the yard, since steep slopes are better suited to a contractor-built raised deck.

Homes near Sunken Meadow and the Nissequogue River can see stronger winds and salt air, especially during nor’easters. Rinse the deck occasionally, check that it is still tight and level each spring, and seal pressure-treated wood every one to two years. Composite decking in Amazon Gray or Forest Wood never needs staining.

Late spring through early fall is the most comfortable stretch, and finishing by Memorial Day gives you the whole summer outside. Order in late winter, since curbside delivery typically takes 10–14 business days, and leave time to confirm permit requirements with the Town of Smithtown.

Pressure-treated wood kits come in 15 sizes: Standard 12x12, 12x18, 12x20, 12x24, 12x28, 16x16, 16x20, 16x24 and 16x28, plus Compact 6x12, 6x16, 6x20, 8x12, 8x16 and 8x20. Composite kits come in 9 sizes from 12x12 to 16x28 in Amazon Gray or Forest Wood. Custom sizes are available on request.
