How Old Is the Framing Under Winston-Salem Homes?
Based on U.S. Census Bureau survey data, the median Winston-Salem home was built in 1979, and about 51 percent of all 112,191 housing units counted, apartments and attached homes included, were built before 1980. More of them went up in the 1970s than in any other decade, 17,471 homes.
Based on NOAA 1991 to 2020 climate normals for Piedmont Triad International Airport, about 18 miles away, the average July dew point near Winston-Salem is about 67 degrees. Dew point is the temperature at which water condenses out of the air, so in a vented crawl space, July air can leave water on the posts, beams and joists that are cooler than about 67 degrees.
Under a home built in 1979, the original posts, beams and joists have carried the floor for about 47 years.

| 1940s | 5,103 | 5% |

The ground in Winston-Salem
How Does Winston-Salem Soil Affect Crawl Spaces?
The USDA sample inside Winston-Salem is mostly Fairview soil, a deep red clay. Of the five points the USDA sampled inside Winston-Salem, four are Fairview and one is Codorus. Across Forsyth County, Fairview covers more than a quarter of the land, with Clifford, Tomlin and Poplar Forest the next most common. The USDA rates the sample inside Winston-Salem low for swelling and shrinking.
Fairview is a deep soil that formed in place as pale rock such as granite and gneiss beneath it weathered, usually found on ridges and hillsides. Its top layer is sandy clay loam, and under that is red clay. Loam is soil with a mix of sand, silt and clay. It drains well, and the USDA rates it low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Codorus is a deep soil that formed from sediment laid down by streams, usually found on stream flood plains. Its top layer is silt loam, and under that is brown loam. It drains somewhat slowly, and it can stay wet near the surface for part of the year.
What It Means for Your Home
- What works in your favorFairview drains well, so rain usually soaks away instead of collecting on the crawl space floor. It also changes size very little as it wets and dries, so the piers and footings under a crawl space sit on steady ground.
- What to watchEven soil that drains well can stay wet where roof runoff collects or the ground slopes toward the house, and that water can reach a crawl space floor. The ground under a house also gives off moisture, and with humid summer air through open vents, the air there can stay damp, which can lead to musty odors, mold and wood rot over time.
- Signs you might noticeLook for moisture in the crawl space, sagging floors, and deteriorating insulation.
- How we address itWhere water reaches the floor, an interior crawl space drainage system that carries it to a sump pump is part of the repair plan. For damp air, our usual recommendation is crawl space encapsulation with a dehumidifier, and where the wood has weakened, crawl space structural repair.
Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov. Inside Winston-Salem, the survey maps Fairview and Codorus series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.5 percent). Across Forsyth County, it maps Fairview, Clifford, Tomlin and Poplar Forest series. Series descriptions: USDA NRCS Official Series Descriptions for Fairview and Codorus.

- Groundwater SeepageGroundwater seepage is water entering the crawl space from the ground itself.

What Do Homeowners Say?
Dalton & Ben did an amazing job with my crawlspace work, which included an interior french drain, sump pump, and sealing. They were easy to communicate with and went above and beyond to ensure I knew what was happening. I would highly recommend this company and install team. Thanks Dalton & Ben!!
Needed an estimate for a home I was going to purchase after discovering the crawl space had moisture issues during my home inspection. Tracie answered my call after hours and was able to get me scheduled for the next day as time was of the essence for me to decide on the property. Tracie was a pleasure to speak with and extremely helpful. Justus came out to the home the next day and was awesome! He was honest, professional and thorough. Thank you for your help! I did not end up continuing with the purchase but if I ever need their services I would not hesitate to call.
I contacted hydro Help 911 because my crawl space is in bad shape as I have an older house. Tracie was especially helpful, kind, and prompt with scheduling someone out. I can’t wait to see how it goes and hope to be able to take care of this problem.
