At Monument Street, Connaughton Construction completed a historic preservation with a large addition to this 100+ year old house. This restoration brought back its original grace while updating its infrastructure. A 3-bay garage, connected by a covered walkway, was added to the house. A 1,200 square foot guest house was renovated for the home owners to live in before beginning work on the main house.

Main House Historic Preservation

Main house renovations included HVAC (hydro-air), plumbing and electrical systems. Bathrooms were replaced with new plumbing fixtures and imported tile and marble. The roof was replaced with red cedar shingle and copper flashing. Many old porch railings and columns were duplicated and replaced after years of neglect.

Carpenter ant damage was prevalent at the house’s rear wing, requiring extensive replacement to the floor joists and wall framing. Quite a bit of shoring and jacking had to be performed to many structural members while preserving the main roof and upper wall framing. This wing was converted to a two-story cathedral ceiling family room with a second floor balcony and new masonry fireplace. On the third floor a study with custom built-cabinets and a home theater were built.

During construction, an old leaky oil tank was found in a vault below the main entrance and removed. This required cutting out a 16 foot section in the main foundation, carefully removing the tank, and then excavating and disposing of the contaminated soil.
