This expanded colonial in the Old Mill area offers thoughtful upgrades, quality construction, and exceptional maintenance throughout. Custom builder modifications added additional living space on both levels, expanded the garage and front porch, and included a family room addition behind the garage, creating a layout that stands apart from similar homes in the neighborhood.

During construction, the owners carefully monitored the build process and upgraded the home with natural wood trim and solid wood interior and closet doors throughout. Their attention to detail continued well beyond construction, with consistent maintenance and major system improvements over the years.

Updates include a roof with 50-year shingles and a premium ventilation system, plus the full HVAC system was replaced in 2024 with high-end Carrier units. All windows have been replaced (all but 4 with Andersen windows). Outdoor living spaces include a sunroom with sliders leading to a paver patio with a pergola, an additional patio area, paver driveway and walkway, and brick planters.

The basement storage area is protected by a waterproofing system with a transferable warranty and two sump pumps. Additional long-term maintenance items include regularly serviced systems and the replacement of the water heater heating element every five years. Some furnishings will convey if desired. If quality construction, expanded living space, and meticulous upkeep are priorities, this home is a must-see.
