When Were Most Concord Homes Built?
Based on U.S. Census Bureau survey data, the median Concord home was built in 1996, and about 30 percent of all 41,988 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, 9,547 homes.
Based on NOAA 1991 to 2020 climate normals for Charlotte Douglas Airport, about 22 miles away, the average July dew point near Concord is about 68 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 68 degrees.

The ground in Concord
How Does Concord Soil Affect Crawl Spaces?
The USDA sample inside Concord is mostly Iredell soil, a brown clay. In a USDA sample of five points inside Concord, three are Iredell, one is Mecklenburg and one is Cecil. Countywide, the most common soil in Cabarrus County is Enon, on more than a tenth of the land, with Cecil, Badin and Mecklenburg behind it. The USDA rates the sample inside Concord very high for swelling and shrinking, which means it swells a lot when it gets wet and shrinks a lot as it dries.
Iredell is a soil that formed in place as darker rock rich in iron and magnesium beneath it weathered, usually found on Piedmont uplands. Its top layer is sandy loam, and under that is brown clay. Loam is soil with a mix of sand, silt and clay. It drains a little slowly, so it can stay wet for short periods in a wet season.
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. It drains well.
What It Means for Your Home
- What to watchClay holds water after long rains and gives it back slowly, so the ground under a crawl space can stay damp and keep adding moisture to the air. Open vents let in humid summer air on top of that.
- Signs you might noticeLook for high humidity under the house, musty odors, and condensation on HVAC vents.
- 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 Concord, the survey maps Iredell, Mecklenburg and Cecil series. USDA rates the soil very high for swelling and shrinking (weighted linear extensibility 11.5 percent). Across Cabarrus County, it maps Enon, Cecil, Badin and Mecklenburg series. Series descriptions: USDA NRCS Official Series Descriptions for Iredell and Mecklenburg.
Our approach
How Do We Approach Crawl Space Encapsulation in Concord?
Most crawl space problems in Concord 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 Concord?
- 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.

What Homeowners Say About Our Huntersville Office
JJ did a great job giving me advice and a through inspection. I am really considering all the benefits of a full encapsulation.
My crawl space dehumidifier stopped working over the weekend. Stephen made sure he came out today (Monday) to check out the dehumidifier and solve the issue. Stephen is alway professional and patient. He takes the time to answer all my questions and stays until the problem is solved. Thank you Stephen for your dedication to making sure that your customers are taken care of.
