Smithtown is one of Long Island's older North Shore towns — settled in 1665 — and its housing shows it: established colonials, ranches, and expanded capes set on mature, wooded lots across Kings Park, St. James, Nesconset, Commack, and Hauppauge. Doors on homes like these have often been in place for decades, and years of North Shore weather take their toll. Just Enterprise One Corp. replaces and installs every kind of door for Smithtown homeowners — entry systems, sliding glass and French doors, storm doors, and interior passage, pocket, and closet doors.
Up here the weather is the real test. Heavy Nor'easters drive rain against exterior doors, and the freeze-thaw cycles of a North Shore winter work loose any door that wasn't sealed and shimmed correctly — which is how you end up with sticking, drafts, and rot at the sill. We flash, shim, and weather-seal every entry door so it stays tight through the season, and on shaded, tree-heavy lots where doors stay damp and collect leaf debris, we pay extra attention to drainage at the threshold. For patio and French doors we install Andersen units and can special-order to match an existing opening.
Because so many Smithtown homes are established colonials with real character, matching matters. Our carpenters cope and trim casing to blend new doors into existing woodwork, and paint to match what's already there. Most projects finish in one to three days. When a door change means widening an opening or altering framing, the permit runs through the Town of Smithtown building department and we bring in a licensed engineer — we manage that process from application to sign-off.
