Crawl spaces in High Point
When Were Most High Point Homes Built?
Based on U.S. Census Bureau survey data, the median High Point home was built in 1985, and about 45 percent of all 47,861 housing units counted, apartments and attached homes included, were built before 1980. More of them went up in the 2000s than in any other decade, 9,765 homes.
Based on NOAA 1991 to 2020 climate normals for Piedmont Triad International Airport, about 8 miles away, the average July dew point near High Point 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 a pipe, duct or joist that is cooler than about 67 degrees.

The ground in High Point
How Does High Point Soil Affect Crawl Spaces?
The USDA sample inside High Point is mostly Mecklenburg soil, a deep yellowish red clay. Of the five points the USDA sampled inside High Point, three are Mecklenburg, one is Vance and one is Enon. Across Guilford County as a whole, the most common soil is Enon, covering about a fifth of the land, followed by Cecil, Clifford and Mecklenburg. The USDA rates the sample inside High Point moderate for swelling and shrinking.
Mecklenburg is a deep soil that formed in place as darker rock rich in iron and magnesium beneath it weathered, usually found on ridges and hillsides. Its top layer is loam, and under that is yellowish red clay. Loam is soil with a mix of sand, silt and clay. It drains well, and the USDA rates it moderate for swelling and shrinking, which means it swells noticeably when it gets wet and shrinks as it dries.
Vance is a moderately deep soil that formed in place as pale rock such as granite and gneiss beneath it weathered. Soft, weathered rock lies a few feet down, and hard bedrock lies much deeper. Its top layer is sandy loam, and under that is yellowish brown clay. It drains well.
What It Means for Your Home
- What works in your favorMecklenburg drains well, so rain usually soaks away instead of collecting on the crawl space floor.
- What to watchEven soil that drains well can stay wet where roof runoff collects beside a house, and the ground under a crawl space still gives off moisture into the air. Open vents let in humid summer air on top of that.
- Signs you might noticeLook for musty odors, condensation on HVAC vents, and cold floors.
- How we address itOur usual recommendation is full encapsulation: a sealed vapor barrier over the ground, walls and piers, a crawl space dehumidifier, and sealed vents, which stay closed once the space is encapsulated. Where water reaches the floor, a drainage system is part of the job.
Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov. Inside High Point, the survey maps Mecklenburg, Vance and Enon series. USDA rates the soil moderate for swelling and shrinking (weighted linear extensibility 5.5 percent). Across Guilford County, it maps Enon, Cecil, Clifford and Mecklenburg series. Series descriptions: USDA NRCS Official Series Descriptions for Mecklenburg and Vance.
Our approach
How Do We Approach Crawl Space Encapsulation in High Point?
Most crawl space problems in High Point come down to one thing: moisture. A vented crawl space in our climate is exposed to bare soil below and warm, humid outside air flowing in through the vents, and that combination keeps the space damp for much of the year.
Crawl space encapsulation is the process of sealing the crawl space into a clean, dry, controlled environment.
It usually combines a heavy liner across the floor, up the foundation walls and around the piers, sealed foundation vents that stop humid air from entering, insulation where it belongs, and humidity control with a dehumidifier installed in the crawl space, plus interior drainage where water gets in.
The result is a crawl space that no longer feeds moisture into the framing, ductwork, and insulation above it. Homeowners often notice lower humidity in the rooms above and less of a musty smell.
Our process is simple:
- A free inspection to find where the moisture is coming from
- A plain explanation of what we see
- A recommendation built around your crawl space
Some homes need full encapsulation with a dehumidifier and interior drainage; others need only a vapor barrier and sealed vents. The crawl space encapsulation warning signs and the crawl space encapsulation solutions explain each one in plain terms.

Problem signs
What Are the Signs You May Need Crawl Space Encapsulation in High Point?
- High Humidity LevelsHigh humidity in a crawl space is moisture held in the air beneath your home, a separate condition from standing water, though the two often occur together.
- Musty OdorsA musty odor is a stale, earthy smell like a damp basement, usually strongest in lower rooms, near floor vents, and on humid days.
- Standing Water in Crawl SpaceStanding water in a crawl space is liquid water collected on the floor, on the vapor barrier, or in low spots over the soil.
- Condensation on HVAC VentsCondensation on HVAC vents and ducts is water that forms on cooler registers, supply boots, and ductwork when the surrounding air is warm and humid enough to reach its dew point, the same way a cold glass sweats in summer.
- Cold Floors Above Crawl SpaceCold floors above a crawl space feel noticeably cooler than the room air, often across a whole room or hallway, and most of all in a Carolina winter.
