Syosset is a hamlet in the Town of Oyster Bay with a dense, well-established residential mix — colonials, split-levels, and ranches on lots ranging from modest quarter-acres to larger wooded properties. It's one of the most requested towns in our Nassau County service area.
We build sunrooms in Syosset regularly. The housing stock here is well-suited to three-season porch additions and four-season room replacements for old-style patios. Most Syosset lots have usable rear space, and the neighborhood density means neighbors appreciate having an enclosed room rather than an open patio.
Common jobs we do in Syosset:
The Town of Oyster Bay Building Department handles permits for Syosset. We know the setback rules, energy code requirements, and typical review times. We submit complete permit packages and handle inspection scheduling.
What does a sunroom cost in Syosset?
Three-season rooms for a typical Syosset home run $25,000–$40,000 for 150–180 sq ft. Four-season insulated rooms typically start at $45,000–$75,000. We give you a firm fixed-price quote after the in-home measurement — no surprise change orders.
How long does the Town of Oyster Bay permit process take for Syosset?
Generally 4–7 weeks from submission to permit issuance. We submit complete drawing packages to minimize revisions. Once permits are in hand, most Syosset installations take 2–4 weeks.
What's the best sunroom type for a Syosset colonial?
Colonials typically have a rear door that steps down to the backyard, which makes a grade-level three-season or four-season room the most natural fit. We can also build off a second-floor deck if your home has one. We'll show you options during the free estimate.
Do you serve Woodbury, Jericho, and Cold Spring Hills too?
Yes. Syosset borders Woodbury, Jericho, Cold Spring Hills, and Muttontown — we serve all of them regularly. Our Nassau County team covers the full Town of Oyster Bay service area.
Can you match the exterior finish to my existing home?
Yes. We offer frames in white, bronze, dark bronze, and custom colors. We can also coordinate with your siding material and roofline for a seamless look from the exterior.

“Tom and his crew built our four-season sunroom in under three weeks. We use it every single day, even in January. Best investment we made in this house.”
Jennifer M.
Massapequa, Nassau County
“We had a three-season room built last spring. By October we were still using it comfortably. The window quality and insulation are impressive for the price point.”
David W.
Garden City, Nassau County
“Tom gave us an honest assessment — told us our deck wasn't suitable for a full four-season room and recommended a three-season instead. Saved us $20k and we love the result.”
Susan T.
Great Neck, Nassau County
“Had a leaking sunroom installed by another company five years ago. Tom's team ripped it down, fixed the foundation issues, and built a proper four-season room. Night and day difference.”
Karen B.
Manhasset, Nassau County
“Replaced an old screened porch with a proper three-season sunroom. The difference in build quality is obvious. Solid framing, clean welds, no rattling when the wind picks up.”
Thomas H.
Merrick, Nassau County
“We live on a corner lot in Levittown and thought we didn't have room for a sunroom. Tom found a way to make it work with a 12x14 footprint off the kitchen. Perfect fit.”
