Deck Builder in Islip Terrace, East Islip and Islip, NY
Level Line builds decks and outdoor living spaces in Islip Terrace, East Islip and Islip, three hamlets of the Town of Islip on Suffolk County's South Shore, from the inland blocks of Islip Terrace down through East Islip and Islip to the Great South Bay.
Deck builder in Islip Terrace
Islip Terrace sits inland, north of East Islip and south of Central Islip, in the Town of Islip. There is no bulkhead and no flood elevation to design around here, so a deck in Islip Terrace is a backyard job: how the deck meets the house, how it comes down to the lawn, and how much of the yard it should take. Much of the housing is mid-century, capes, ranches and hi-ranches on regular suburban lots, which is why so many Islip Terrace decks are either a ground-level platform off a kitchen slider or a raised deck with a landing and a stair run where the main floor sits above the yard.
Pool decks are a common Islip Terrace job, and one Level Line builds: decking around an above-ground pool, or a deck that runs up to the edge of an in-ground one, with the ladder or the steps landing where they should. Composite and PVC boards are the usual choice around a pool because they do not splinter and they shrug off the water, and the same lines Level Line installs everywhere else in the town are the ones that go in here.
Every permit in Islip Terrace runs through the Town of Islip, because the hamlet has no village government of its own. Level Line prepares the drawings for the application, unless an architect is assigned to the job. You submit the application with what Level Line provides, Level Line arranges and attends the inspections, and Mark is available by phone throughout. How long approval takes varies by town and by inspector. A build runs from one day to two to four weeks depending on size and scope, and the estimate at the house is free.
Deck builder in East Islip
East Islip leans toward ranches, hi-ranches and colonials on generous lots with real backyards and mature trees, which means there is usually room for a deck that does more than hold a grill. Bigger lots also mean longer sight lines, so we pay attention to how the deck reads from the yard, not just from the back door.
South of Montauk Highway the hamlet runs down to the Great South Bay beside Heckscher State Park, and on the bay-side blocks the job changes: salt air reaches the hardware, the layout has to respect the flood elevation, and the railing is chosen to keep the view. North of the highway an East Islip deck is a straightforward backyard build, sized to the lot and the house.
East Islip permits go through the Town of Islip, the same route as Islip Terrace and Islip: Level Line prepares the drawings for the application, unless an architect is assigned to the job. You submit the application with what Level Line provides, Level Line arranges and attends the inspections, and Mark is available by phone throughout. The three photos further down this page are a Level Line deck in East Islip.
Deck builder in Islip
Islip is the hamlet the town is named for, west of East Islip along Main Street, and Level Line builds decks and outdoor living spaces throughout it, from the blocks near the Great South Bay inland.
Islip hamlet is the seat of the Town of Islip, and the housing reflects both its age and its waterfront: grand older colonials and detailed homes near the bay alongside suburban ranches and splits further inland. On bay- and canal-front lots the job changes: salt-rated hardware, careful attention to the flood elevation, and a layout built around the water view. On the older homes near the water, the railing profiles and trim have to read as part of the original architecture rather than an addition bolted to the back.
Islip has no village government of its own, so its permits run through the Town of Islip like the rest of this page. Level Line prepares the drawings for the application, unless an architect is assigned to the job. You submit the application with what Level Line provides, Level Line arranges and attends the inspections, and Mark is available by phone throughout. On a bay-front or canal-front lot the footings, the flood elevation and the salt-rated hardware are worked out at the estimate, before anything is filed.
Decking we install in East Islip
Level Line installs the composite and PVC lines that resist rot, warping and fading in salt air and sun, and the natural woods for homeowners who want the real thing. For Trex, TimberTech, Azek and Fiberon, Level Line is a manufacturer-certified installer.
Trex
Composite decking. Manufacturer-certified installer.
TimberTech
Composite decking. Manufacturer-certified installer.
Azek
PVC decking. Manufacturer-certified installer.
Fiberon
Composite decking. Manufacturer-certified installer.
Cedar
Natural wood with its own color and grain. It needs regular upkeep near the water.
Pressure-treated lumber
The traditional wood deck board. It needs staining or sealing and regular upkeep over its life.
Mahogany
A hardwood board for a homeowner who wants real wood underfoot.
Ipe
A dense tropical hardwood. Like every natural wood it asks for regular maintenance.
Which board suits your deck depends on the exposure, the look you want and the upkeep you are willing to do. We walk through the choices with you at the estimate.
Railings
Level Line installs every railing line: Trex Signature, TimberTech, cable rail, aluminum picket and wood. On the bay-side blocks of East Islip and Islip the usual choice is cable rail or aluminum picket, which keep the water in view; inland in Islip Terrace a composite or wood railing to match the decking is the common pick. The railing is chosen with the boards at the estimate.
Deck lighting
Deck lighting is part of what Level Line builds. Low-voltage post-cap lights, stair lights and rail lights are an option on any deck, and they go in as the deck is built, so the wiring runs inside the frame and the fixtures sit where the posts and stair stringers can carry them. Lights on the stairs mark the step edges after dark, and lights along the rail keep the deck in use after sunset without lighting up the whole yard.
How we build in the Town of Islip
Footings
The footings are sized and set for the ground under the deck. Inland in Islip Terrace that is a regular backyard footing; on a bay-side lot in East Islip or Islip it also has to meet the flood elevation the layout is designed around. They carry everything above them, so they are the part of the job nobody sees and the part that matters most.
Framing
The frame is sized for the deck it carries: the spans, the stairs, and the weight of anything built on it, from an outdoor kitchen to a hot tub. Where the main floor sits above the yard, a raised deck gets a landing and a stair run with a comfortable rise, and the railings meet code.
Salt-rated hardware near the bay
Every deck is tied down with hurricane clips and wind-uplift connectors, and on the bay-side blocks of East Islip and Islip every hanger, bracket, bolt and fastener is rated for salt exposure, because the salt air works on metal from the day the deck is finished. The railing is picked for the view as much as for the code.

What homeowners say about Level Line
Level line was Awesome!!! Mark and the guys were Top notch. They built my deck with total precision. Every Board was perfectly in line and all their cuts were flawless! The deck came out better than I can ever have imagined!! True craftsmanship!!

Mark and his crew of workers were exceptional. They completed a deck enclosing a 12' round pool for my home. Every step of the way, Mark was in contact with me and updating me on progress. He also built the deck to accommodate the pavers that we were going to install after the deck was done. His work was top notch, be it the initial planning, construction, or finish work. I highly recommend getting your construction done by this company.
