When Were Most Matthews Homes Built?
Based on U.S. Census Bureau survey data, the median Matthews home was built in 1992, and about 18 percent of all 11,737 housing units counted, apartments and attached homes included, were built before 1980. More of them went up in the 1990s than in any other decade, 3,027 homes.
Based on NOAA 1991 to 2020 climate normals for Charlotte Douglas Airport, about 16 miles away, the average July dew point near Matthews 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 Matthews
How Does Matthews Soil Affect Crawl Spaces?
All five points the USDA sampled inside Matthews are Cecil soil, a deep red clay. Across Mecklenburg County, Cecil covers more than a third of the land, with Wilkes, Enon and Monacan the next most common. The USDA rates the sample inside Matthews low for swelling and shrinking.
Cecil 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 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.
What It Means for Your Home
- What works in your favorCecil 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 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, and humid air there can lead to musty odors, mold and wood rot over time.
- 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 Matthews, the survey maps Cecil series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.5 percent). Across Mecklenburg County, it maps Cecil, Wilkes, Enon and Monacan series. Series descriptions: USDA NRCS Official Series Descriptions for Cecil.
Our approach
How Do We Approach Crawl Space Encapsulation in Matthews?
Most crawl space problems in Matthews 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 Matthews?
- 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.
