About Watha and Its Homes
Watha began around 1840, when the older village of South Washington, laid out by Welsh settlers in 1740, moved about a mile and a half to sit beside the new railroad. It was incorporated in 1909, and beyond a few entries in the county survey, its houses have hardly been written about.
Watha, in Pender County, grew from 181 people in 2020 to 226 in 2025 (Census Bureau estimates), on 1.36 square miles.

The Local Climate
Watha's center sits about 60 feet above sea level, 5 miles from NOAA's Willard 4 SW station, the best match for Watha. The station's 1991 to 2020 normals average about 2,830 heating and 1,620 cooling degree days a year, so at Watha's station, heating needs outweigh cooling. The state energy code marks Pender County warm and humid.

Watha Insulation FAQs
Is my Watha house listed as historic anywhere?
Not on any state list. The National Register rows for Pender County include no place in Watha, and no local preservation commission for Pender County appears in the state directory of 2023. The 1997 county survey did record a few Watha buildings, among them a house of about 1865 with zig-zag trim under its eaves and two churches from 1907 and 1908. Being written up in a survey does not designate a building. No historic rule applies to attic work here.
What has to be checked before an older Watha house gets attic insulation?
Three things come before any new insulation. Wiring first: per ENERGY STAR, the old knob-and-tube kind from before about 1930 turns into a fire risk once insulation covers it, so an electrician decides what stays. Then vents: a kitchen, bath or dryer fan that dumps into the attic gets routed outside. Last, the roof boards, because damp or stained insulation means a leak to repair first. In a town incorporated in 1909, with a house recorded from the 1860s, all three can come up.
Does attic insulation in Watha need a permit?
Watha Town Hall can say whether Pender County Planning & Community Development, the town itself or another office handles permits in Watha; ask before work starts.
