Crawl Encapsulation in Kernersville, North Carolina

Crawl spaces in Kernersville

Kernersville is the largest suburb of Winston-Salem and one of the fastest-growing towns in the Triad, with about 26,500 people at the 2020 census, up from about 23,000 in 2010. It sits mostly in eastern Forsyth County, with a small part in Guilford, and Interstate 40 and Business 40 tie it to both Greensboro and Winston-Salem. The town began as a crossroads tavern in the 1700s, took the name Kerner’s Crossroads after Joseph Kerner bought the property in 1817, and was incorporated as Kernersville in 1873. Its most famous house, Körner’s Folly, was built downtown in the 1880s.

Three kinds of homes, three kinds of crawls

• **Historic homes near downtown.** Older houses often have brick foundations, low clearance in places, and decades of changes underneath. We check wood condition and plan around old pipes and wiring.
• **Mid-century brick ranches.** Built from the 1950s to the 1980s, often with ductwork and an air handler in a vented crawl, thin plastic on the ground and fiberglass between the joists.
• **Newer subdivisions.** Taller crawls and more ductwork. Some newer homes were built with closed crawls; many were not.

Moisture patterns we see

The Triad’s humid summers are the main problem in most Kernersville crawls. Outside air comes in through the vents, meets cooler surfaces, and condenses. Many homeowners notice a musty smell or higher indoor humidity from June through September. In homes with ducts in the crawl, the duct wrap often gets wet and sags.

Water is the second problem. Kernersville’s rolling terrain means some homes sit below the street or below a neighbor’s yard, and red clay holds runoff against foundations. Water lines on the block walls and damp soil after storms tell us drainage needs attention before a liner.

Sealing a crawl the right way

A full encapsulation here usually means clearing out old plastic and wet insulation, fixing water issues, installing a sealed liner on the ground and walls, closing the vents, and adding a dehumidifier. North Carolina code sets out how closed crawls must be built, and we follow it. Read about dehumidifiers in sealed crawls.

Signs to watch for in Kernersville homes

• A musty smell in the house that is strongest on humid summer days.
• Indoor humidity that stays above 60 percent even with the air conditioner running.
• Cupping or gapping in hardwood floors over the crawl.
• Rust on the air handler cabinet, or duct wrap that sags or drips.
• Insects, mice or snakes in or around the crawl access.

Any one of these is a reason to take a look under the house. Several together usually mean the crawl is driving the moisture problem in the home. Our crawl moisture guide explains what to check yourself before you call.
