Northport is a historic harbor village on Northport Bay, and its housing shows it — 19th-century Victorians, older colonials, and waterfront homes near Long Island Sound, many with original or first-replacement windows still in place. Those older units leak heat, stick in their frames, and let in the damp salt air that rolls off the Sound. New double-pane vinyl, fiberglass, or wood windows with low-E coatings seal the house up, cut energy bills, and stand up to coastal moisture far better than what they replace. Just Enterprise One Corp. has worked on Northport, East Northport, and Fort Salonga homes since 1989.
Older Northport homes come with older-home surprises — out-of-square openings, hidden rot behind the sills, and decades of paint and settling. We assess each opening on its own: where the frame is sound, an insert replacement preserves the original casing and interior trim that give these houses their character; where salt air and age have taken the frame, a full frame-out lets us repair the moisture damage properly and reseal the opening. For the village's Victorians and colonials, we match window profiles and grille patterns so the replacements suit the architecture rather than fight it.
We install a range of vinyl, fiberglass, and wood window lines at different price points — including Andersen, which we're certified to install — with proper flashing, foam-sealed rough openings, and finished casing inside and out. Permitting in Northport can involve both the incorporated Village of Northport and the Town of Huntington depending on where your home sits, and we handle that paperwork so you don't have to. When an opening in an older home needs to be reframed or enlarged, we bring in a licensed engineer.
