Homes around this lab
Guilford County: 41% of 238,032 housing units were built before 1980, above the North Carolina share of 34% (Census ACS 2020–2024, table B25034). EPA links lead-based paint to homes built before 1978, and asbestos was common in building materials of that era. The ACS groups years by decade, so 1980 is the nearest cut.
Older homes within 25 miles
About 232,727 homes built before 1980 are in the 4 counties whose centre lies within 25 miles of this lab (Davidson County, Forsyth County, Guilford County, Randolph County).
- Asbestos testing: 2 accredited lab sites within 25 miles, about 116,364 older homes per site, fewer than the North Carolina figure of 276,965 older homes per listed site (6 sites).
- Lead paint testing: 2 accredited lab sites within 25 miles, about 116,364 older homes per site, fewer than the North Carolina figure of 332,358 older homes per listed site (5 sites).
