Welcome to 1402 Endingo Avenue, Energy-efficient, move-in ready, and set on nearly half an acre. A beautifully maintained 4-bedroom, 2.5-bath Colonial in Williamstown’s desirable Tall Oaks community, built for comfort, style, and serious energy savings. A covered front porch, paver walkway, and mature landscaping with a Japanese maple and a weeping evergreen set an inviting tone from the curb. Behind that classic look is a home that has been thoughtfully upgraded to lower your monthly costs: a newer roof (2020) with solar panels, new energy-efficient windows (2025), a new sliding glass door, a tankless water heater for endless on-demand hot water, new AC unit (2025), and an irrigation well that keeps the lawn green without running up the water bill. This combination is hard to find, and it makes this home as smart to own as it is lovely to live in. Step inside to gleaming hand-scraped hardwood floors that flow through the foyer, living room, and dining room. The spacious living room is filled with natural light, and it opens to a formal dining room with crown molding and a large window overlooking the backyard, perfect for holidays and gatherings. An updated powder room with a modern vanity is conveniently located on the main level. The updated kitchen is the heart of the home. It features crisp white shaker cabinetry with matte black hardware, white quartz countertops, a designer patterned tile backsplash, stainless steel appliances including a gas range, and a beadboard-trimmed peninsula. Modern pendant lighting hangs above a sunny breakfast area, where the new oversized sliding glass door leads directly to the deck. A main-level laundry room sits just off the kitchen. A few steps down, the family room offers a cozy, separate space for movie nights, with rich wood flooring and an open sightline back to the kitchen. Upstairs, the generous primary suite has windows on two sides overlooking the wooded backyard, plus a private en-suite bath with a double vanity, a corner soaking tub, and a separate shower. Three additional bedrooms offer neutral carpet and great natural light, and one works perfectly as a home office. A full hall bath serves the secondary bedrooms. The finished basement adds a large amount of extra living space with recessed lighting, carpet, and plenty of room for a media area, game room, home gym, or bar setup. Outside is where this home really shines. The expansive composite deck, with a striking diagonal board pattern and white railings, is made for grilling and entertaining. It overlooks a 0.45-acre oversized lot with a fully fenced backyard, stone fire pit, storage shed, and a private wooded backdrop, giving you room to play, garden, or simply relax. A two-car attached garage completes the package. All of this sits in Tall Oaks, a sought-after neighborhood with easy access to shopping, dining, schools, and major commuter routes, less than 1/2 a mile from a beautiful paved walking/bike path that runs from Glassboro through to Williamstown. Energy-efficient, move-in ready, and on a beautiful lot. 1402 Endingo Avenue is ready to welcome you home. Schedule your showing today!
