This beautifully maintained 2,358 sq ft colonial offers an exceptional layout and upgraded amenities throughout, set on a private .51-acre lot in Port Jefferson Station. Inside, the home boasts gleaming hardwood floors, crown molding, wainscoting, chair rails, and abundant natural light. A cozy, wood-burning fireplace enhances the den, and ceiling fans in multiple rooms provide year-round comfort. The full finished basement features brand-new flooring and offers flexible space perfect for a home office, media room, or playroom. The kitchen is thoughtfully updated with new flooring, a stainless steel refrigerator (2 years old), stainless steel dishwasher (1 year old), and a fire-rated door providing secure access to the oversized 2.5-car garage. Upstairs, all bedrooms are generously sized with walk-in closets, and the primary bath is outfitted with a quartz vanity and matching quartz shower surround. Comfort and efficiency are key here, with a Lennox central air system, built-in whole-house dehumidifier, two HEPA filters, a dedicated hot water tank, and an attic fan. Eleven windows have been recently replaced, and six have been upgraded to Andersen for enhanced insulation and durability. Step outside to enjoy a beautifully manicured yard with lush landscaping, a fully updated front walkway (2024), an in-ground sprinkler system, and exterior security lighting—all tucked away on a peaceful cul-de-sac. 7 Jacqueline Court is more than just a home—it’s a lifestyle of comfort, quality, and quiet elegance in a highly desirable location.
