Glenwood Landing is a hamlet in the Town of North Hempstead on Nassau County's North Shore — a waterfront community on Hempstead Harbor with a mix of cape cods, colonials, and ranch homes. The proximity to the harbor and Long Island Sound makes outdoor living central to life here, and sunrooms are one of the best ways to capture water views year-round.
We serve Glenwood Landing as part of our North Shore service area. Permits go through the Town of North Hempstead Building Department. We've worked with this office many times and handle all permit research and submissions.

How do I maximize harbor views with a sunroom?

Homeowner Reviews
Nearby Nassau County homeowners — we build across the same building departments, codes, and soil conditions.
“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.”
