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.
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.
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.
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.
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.
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.
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.
