Kevin showed up exactly when he said, walked my yard, and had a quote in my inbox the same day. The 14×20 cedar pergola came out even better than the photos online. My neighbors keep asking who built it.

Michael D.Huntington · Cedar Pergola

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. Zero stress.

Lisa R.Massapequa · Wood Shed

Third time using Long Island Shed Builders. First a shed in 2019, then a pergola in 2022, now a gazebo for the pool area. Every time Kevin delivers exactly what he promised.

Frank & Joanne T.Commack · Pool Gazebo

The hardtop gazebo they installed by our pool is stunning. They handled everything including the electric run for the ceiling fan. Price was fair and the craftsmanship is exactly what I expected from 13 years in business.

Patricia M.Garden City · Hardtop Gazebo

Had three other quotes. Long Island Shed Builders was the only one who came back with a drawing the same week and actually knew what a Nassau permit required. Worth every penny.

Rob K.Smithtown · Custom Shed

I wanted a screened pavilion for outdoor dining. Anthony had photos of similar projects on other properties — that alone sold me. It came out perfect. Whole family eats outside now.

Danielle S.Babylon · Screened Pavilion

Custom-Built on Long Island. Not a kit. Not a drop-off.

We frame every shed, gazebo, and pergola on-site to your exact dimensions using pressure-treated lumber that handles Nassau and Suffolk County's coastal humidity. Permits handled in every LI municipality — included in your written quote.

Sheds up to 144 sqft can often be placed without a permit (skid foundation). Larger structures or permanent foundations require permits — we file and track every one.

Common Questions

Before you reach out

It depends on size and your municipality. In most Nassau and Suffolk towns, sheds under 100–144 sq ft on a temporary foundation don't require a permit. Anything on a permanent foundation or over that threshold typically does. We pull permits for all projects that require one — it's included in your quote, not an add-on.

A standard 12×16 wood shed typically takes 1–2 days once the foundation is set. Custom builds or larger structures run 2–4 days. We always give you a firm schedule before we start, and we stick to it.

A pergola has an open lattice or beam roof — it provides shade and structure but lets light and a little rain through. A pavilion has a solid roof (shingles, metal, or polycarbonate), so it's full weather protection. If you want outdoor dining that works even when it's drizzling, a pavilion is the right call.

Yes. We've pulled hundreds of permits across Nassau and Suffolk municipalities. We know what each town requires, which drawings to submit, and how to get approvals without delays. All permit costs are included in your estimate upfront.

We offer pressure-treated skid foundations (no permit in many areas), concrete piers or tube footings, crushed stone beds, and full concrete slabs. The right choice depends on your drainage, soil, and intended use. Kevin walks every site and recommends based on what he sees.

Yes. Our portfolio page has before-and-after photos from 80+ projects across Long Island. You can also see project photos by service type (sheds, pergolas, gazebos, pavilions). We'll also share photos from projects in your specific town during the estimate walk-through.

Yes — we build Long Island sheds from Montauk to the Nassau border. Nassau County, all of Suffolk County, every town in between. We don't subcontract: same crew handles your shed from the foundation to the final trim. No travel fees anywhere on Long Island.

Most Long Island towns allow sheds up to 100–144 sq ft on a temporary skid foundation without a permit. The exact threshold varies by municipality — Hempstead, Oyster Bay, Islip, Smithtown, and Brookhaven all have slightly different rules. We check your specific town before quoting and pull the permit if one is required, at no extra charge.

Long Island shed prices start around $3,500 for a 10×12 wood shed on a pressure-treated skid and go up to $35,000+ for a custom 20×24 finished workshop with electrical and a concrete slab. Most homeowners spend $5,500–$12,000 for a 12×16 to 14×20 build. All quotes include materials, labor, foundation prep, and delivery.

We build with LP SmartSide engineered wood siding, western red cedar, vinyl, and composite panels depending on your preference and budget. Framing is kiln-dried pressure-treated lumber rated for Nassau and Suffolk County's coastal climate. Hardware is hot-dipped galvanized or stainless to resist salt air. Every material spec is in your written quote.

Most Long Island shed installs run 1–3 days for the build itself, depending on size and complexity. Permit turnaround in Nassau and Suffolk typically adds 2–6 weeks before the build date. We schedule your install date the day your permit is approved and stick to it. Same-week installs are possible for permit-exempt sizes.

You can order Long Island sheds from big-box stores, prefab shed dealers, or a custom builder like us. The difference: big-box and prefab sheds are drop-shipped kits with generic dimensions and no permit support. We build every Long Island shed on-site to your exact specs, match siding and trim to your house, and pull all Nassau and Suffolk permits. The installed price is competitive with delivered prefab sheds once you factor in foundation prep, assembly, and permit filing that prefab companies don't include.

We don't deliver prefab sheds — we build Long Island sheds on-site at your property. Our crew arrives with all materials, constructs the shed from the foundation up, and cleans up before leaving. This means your shed fits your exact lot dimensions and meets your municipality's code requirements. No travel fee anywhere in Nassau or Suffolk County.

For tight lots common in Levittown, Hicksville, and South Shore communities, an 8×10 or 10×12 shed maximizes storage without overwhelming the yard. We design narrow-profile and corner-fit sheds that work within tight setback requirements. Vinyl siding keeps maintenance at zero on a small shed. These sizes are typically permit-exempt in most Long Island municipalities.
