Attic Insulation in Mount Pleasant, NC

Mount Pleasant Homes and Their Attics

Greek Revival Houses Older Than Electric Light

The 1986 district nomination dates the oldest house in town to 1840. It describes most of the Greek Revival homes, built up to the early 1860s, as two stories tall and one room deep. A house that old went up long before electric light, so every wire now running through its attic was added later, some of it perhaps a century ago. ENERGY STAR warns that knob-and-tube circuits, common before about 1930, become a fire risk when buried in insulation. In one of these houses, an electrician looks over the attic wiring before any insulation goes in, and live knob-and-tube is left uncovered.

Queen Anne Houses With Vents in the Gables

When four local industries opened around the turn of the century, building picked up again. The nomination calls the two-story L-shaped house, with a wrap-around porch and ornamental vents high in the gables, the most common Queen Anne form in the district, built from 1880 to 1911. Those gable vents are part of how the attic breathes: air comes in low at the eaves and leaves through the gables or ridge. When insulation is added, the eaves stay open behind baffles and the gable openings stay clear. The two wings of an L can also have separate attic spaces, and each one is measured.

Ranch Houses Added to the District in 2024

In 2024, new documentation pushed the district's period of significance forward from about 1935 to about 1976. That brought in Minimal Traditional and Ranch houses, among them a brick Colonial Revival ranch built in 1952. By the town's Census numbers higher up this page, roughly half its homes went up before 1970. A one-story ranch spreads its attic wide under a low roof. The far corners over the outside walls get little headroom. That is where a layer of insulation can come up short, so we check the edges as well as the middle.
