What Customers Say

Long Island shed reviews

We needed a 12×16 shed to clear out the garage. Anthony handled the permit — I didn't have to do a thing. Crew was clean, finished in two days, and cleaned up before they left.

Lisa R.Massapequa · Wood Shed

Kevin's crew built us a 14×20 workshop in Smithtown. The permit process was seamless — they filed everything and got approval in under a month. The shed is exactly what I described.

Tom P.Smithtown · Workshop Shed

I've had shed builders come and go on Long Island. Long Island Shed Builders is different — they show up, they're professional, and the workmanship is excellent. Already recommended to three neighbors.

Custom Shed Builders Long Island — Storage Sheds, Garden Sheds & Workshop Builds

As Long Island's dedicated shed builders since 2011, we've completed 820+ outdoor structure projects across Nassau and Suffolk County. Every Long Island shed we build is framed on-site from pressure-treated lumber rated for the island's coastal climate — no prefab kits, no drop-and-go installations. Whether you need a compact 10×12 garden shed for backyard tool storage in Levittown, a 14×20 workshop shed with electrical rough-in and a concrete slab in Hauppauge, or a finished she-shed retreat in Garden City, we design it around your property, pull the permits, and build it right the first time.

Long Island shed prices start at $3,500 for a basic 10×12 wood shed on a pressure-treated skid foundation and range to $35,000+ for large custom workshops with lofts, finished interiors, and full electrical. The most popular size across Nassau and Suffolk is 12×16 — large enough for a riding mower, workbench, wall shelving, and room to move, typically running $5,500–$12,000 installed. We build with LP SmartSide engineered wood siding, western red cedar, vinyl, and composite panels. All hardware is hot-dipped galvanized or stainless steel to resist Long Island's salt air.

What sets us apart from other shed builders on Long Island is simple: same crew from foundation to final trim, permits included in every quote, and Kevin walks the finished build with you before we leave. We don't subcontract, we don't cut corners on materials, and we match your shed's siding and trim to your house if you want. That's why Long Island homeowners keep calling us back — first for a shed, then a pergola, then a gazebo.

Garden Sheds Long Island — From Small Storage to Backyard Retreats

Garden sheds remain the most requested shed type on Long Island. A well-built garden shed keeps tools, seasonal furniture, holiday decorations, and lawn equipment out of your garage and organized. We build Long Island garden sheds in sizes from 8×10 (fits a push mower, hand tools, and shelving) to 12×16 (room for a riding mower, potting bench, and deep storage). Options include barn-style double doors for wide equipment access, architectural shingle roofs that match your home, and window packages for natural light. Garden shed installations start at $3,500 with a pressure-treated skid foundation — no permit needed in most Nassau and Suffolk towns for sizes under 144 sq ft.
