Welcome to 1849 Dewhurst Avenue, a well-upgraded 3-bedroom backsplit tucked away on one of Cornwall's quietest north-end streets. This home offers a rare combination of modern mechanicals, a whole-home Generac standby generator and a separate basement entrance - features you won't find in any competing listing at this price point. The main level features a spacious living and dining area with dark bamboo flooring and patio doors leading to a large interlock patio and wooden deck with a metal gazebo overlooking the deep, fully fenced backyard. Three bedrooms on the upper level offer bamboo flooring, fresh paint, and great natural light. The full bathroom has been renovated with a modern vanity, and a tub/shower surround. The finished lower level adds real livable space - a generous rec room with bamboo flooring and a fireplace with a gas insert. A basement walkout door leads to an interlock paver patio and offers a private lower-level entrance. The half bath with laundry and a large unfinished utility area provide additional function and storage. Major updates include a York gas furnace (2019), central air conditioning, a metal roof, a 200 amp electrical panel, insulated garage with a new door, and an updated bathroom. The Generac generator with automatic transfer switch ensures whole-home backup power - a standout feature for peace of mind. Outside, the 50' x150' lot is fully fenced with mature trees, professional front landscaping with paver stone walkways and rock beds, a custom-built storage shed, and generous green space. The kitchen retains its original solid wood cabinetry and offers an opportunity for a buyer to personalize to their taste. Located on a quiet, low-traffic street in a desirable pocket of Cornwall's north end, this home delivers where it counts - mechanicals, structure, and lifestyle. Book your showing today.
