Crawl Space Encapsulation in Charlotte
When it’s almost as humid inside your home as it is outside, something’s wrong. In the Carolinas, vented crawl spaces can suck in the damp, warm-weather air we all know and love, raising humidity inside, inviting mold, and undermining your home’s foundation and air quality.
Moisture Loc’s crawl space encapsulation stops that cycle by transforming your open crawl space into a sealed and conditioned area. This keeps moisture, mold, and pests out, while permanently improving the air quality.
- A vapor barrier seals out moisture
- A dehumidifier provides long-term consistency
- HVAC and other systems are protected
- No more mold, rot, and pests
Your house shouldn’t have its own weather.
Encapsulate and keep the moisture out.
What is Crawl Space Encapsulation?
In the Charlotte area, humid summers, heavy rain, and vented crawl spaces create what amounts to a perfect storm (pun intended) for plenty of things you don’t want in your home: moisture, mold, pests, wood rot, allergens, and odors.
Crawl space encapsulation turns your existing crawl space into a clean, dry “room.” (One of the many benefits of encapsulation is creating more livable space in your home.) To encapsulate, we seal off outside vents, insulate the walls, install a heavy-duty vapor barrier, and add a dehumidifier to control humidity year-round.

A Damp Crawl Space Impacts Air Quality and Energy Efficiency
Crawl space encapsulation separates your home from the earth and outside air, significantly improving inside air quality and making your home more energy efficient.
Research shows that homes with encapsulated crawl spaces use roughly 15% less energy for heating and cooling compared to homes with vented crawl spaces.

Our GreenSpace™ Encapsulation System
Every crawl space is different, but most projects follow this proven process:
1: Remove Floor Joist Insulation
If insulation is aged or damaged due to high moisture, it can cause mold growth, create cold or hot spots in your floors, and increase energy loss through weak areas in your flooring.
Removing the old or damaged insulation and replacing it with new insulation improves heating and cooling properties in your home and reduces your risk of mold growth.
2: Seal Seams of Vapor Barrier
The next step in our sealed crawl space encapsulation is installing a durable poly liner. Our crawl space encapsulation technicians place a 17-mil poly liner along the interior crawl space walls, around the interior crawl space piers, and over 100% of the crawl space floor. We tape and caulk the liner so your crawl space stays fully encapsulated. As a result, moisture doesn’t rise from the ground and into your floor system, insulation, and home.
3: Seal Crawl Space Vents
The next step in sealing a crawl space is keeping humid outside air. We secure the vents with a commercial-grade insulating board so hot and cold air from outside can’t get in.
4: Insulate Walls (Optional)
After sealing the vents, we recommend adding insulation to reinforce your crawl space encapsulation. Adding insulation to crawl space walls improves thermal resistance in masonry walls. As a result, it should significantly improve your home’s energy efficiency and conserve heating and cooling costs.
5: Install Dehumidifier
A dehumidifier is an essential step in crawl space encapsulation. Moisture Loc uses dehumidifiers specifically for crawl space or basement applications. The Santa-Fe Dehumidifier is placed into the crawl space to dry out humid air and keep moisture away. This dehumidifier includes a fan that draws in moist, humid air through a cold evaporator coil, effectively cooling the air below its dew point. Once the air temperature is below the dew point, it turns into water, which is collected and automatically drained.
Why Crawl Space Encapsulation
is a Smart Investment
Healthier Air Quality
Up to 40% of the air on the first floor can come from the crawl space. When the crawl space is dry and sealed, you reduce musty odors, mold spores, and allergens.
Energy Efficiency
A sealed, insulated crawl space helps your HVAC run more efficiently and can reduce energy costs.
Protects Structure and
Resale Value
Moisture is the #1 enemy of wood framing. Encapsulation helps prevent rot, cupping floors, and foundation issues — and it’s a selling point for buyers.
Signs You May Need a Crawl Space Encapsulation
Wondering if your crawl space has a problem? Here are the most common warning signs:
- Musty odors in your home
- Standing water, moisture, or condensation
- High indoor humidity
- Sagging or cold floors
- Termite, rodent, or insect infestations
- Rusted HVAC components or ductwork
- Mold on joists or subfloor
