Seal Out Moisture, Boost Home Health
What Crawl Space Encapsulation Is & Why It Matters
Crawl space encapsulation is the act of sealing your home's crawl space in a professional manner to prevent moisture, water vapor, and pest entry into your home. The encapsulation acts as a barrier against mold growth, wood deterioration, air quality problems, and the overall structural integrity of your house. Not only will you have a protected home after doing this, but you will also improve your home's overall energy efficiency by reducing heat loss and reducing HVAC load, as well as improving the air quality that your family breathes.
A home with a sealed crawlspace will experience increased market value and long-lasting durability. Take the next step toward a healthier and more efficient home by scheduling an appointment with Glover Environmental today!
What Is Crawl Space Encapsulation?
Crawl Space Encapsulation is a permanent solution for controlling moisture under your home by covering the floors, walls, and piers of your crawl space with heavy-gauge/vinyl vapor barriers; sealing the vents; and may include installing drainage or sump pumps to eliminate moisture. When used properly, this method will create an environment in your crawl space that is controlled, thus controlling the humidity levels and preventing condensation and reducing the potential for the growth of mold and mildew.
Also, the crawl space encapsulation process will provide protection to wooden beams and floor joists from rot; will reinforce your home's support structure and foundation; and, with the added benefit of conditioning the air in your home, will also help improve the overall indoor air quality. Glover Environmental has developed a complete, customized solution for your unique crawl space by combining sealing, insulating, and possibly installing a dedicated crawl space dehumidifier. Utilizing a professional installer allows for the best long-term performance, provides for easy maintenance, and, over the long term, will provide energy savings to you.
Moisture Issues in Crawl Spaces
Moisture and humidity found within crawl spaces will warp your floors, rust your supports, and produce unpleasant smells. In addition to causing an environment conducive to mold growth, moisture can weaken your crawl space's structural integrity; therefore, managing the moisture in your crawl space is necessary to keep your home safe and healthy.
Encapsulation vs. Traditional Methods
Traditional vapor barriers in crawl spaces often fail due to tears, improper sealing, or insufficient insulation. Crawl space encapsulation goes beyond merely covering the surface area of a crawl space with an impermeable barrier; instead, it includes a fully integrated system for controlling humidity levels, improving energy efficiency, and eliminating moisture throughout the crawl space over time.
Core Components of Encapsulation
The foundation of effective crawl space encapsulation is a heavy-duty vapor barrier, air-tight sealing of vents and walls, and adequate private drainage systems for the proper disposal of water. When installed in combination with one another, these core components provide lasting protection and energy savings while simultaneously increasing comfort throughout your home.
Our Crawl Space Encapsulation Services
Professional Moisture Assessment:
To investigate the potential for moisture entering through any openings during our initial inspection, Glover Environmental will perform an extensive examination of potential moisture sources that expose wood to mold and structural vulnerabilities (crawlspace air vent openings) for the purposes of developing a detailed method of moisture control.
Vapor Barrier installation:
Vapor barriers will physically block moisture from entering through wood onto the exposed crawlspace via the wall and the floor, and will be constructed of high-quality, durable materials such as moisture barrier systems, providing a layer of protection between cool air molecules, damp air pressure, and moisture on the ground below.
Crawl Space Sealing and Insulation:
Ensuring that all vent openings (gaps) and penetrations in the walls of the crawlspaces we insulate are sealed is extremely important when maintaining a safe and healthy crawl space environment. Additionally, our team will provide insulation where it is deemed necessary for energy efficiency, to improve HVAC load on your heating/cooling systems.
Post-encapsulation moisture control:
After the vapour barrier is installed, we implement ongoing moisture management through monitoring the crawl space and humidity management strategies, together with an optional installation of dehumidification units within the crawl space in Raleigh, to protect against future moisture intrusion into the crawl space.

Why IAQ Testing Matters for Crawl Spaces
Testing the indoor air quality through certified professionals will help identify various pollutants and ensure that the encapsulated crawl space will drastically improve your indoor air quality. Indoor air quality evaluations are conducted before any encapsulation and provide guidance for our team in customizing insulation and sealing methods that will eliminate all contaminants.
Detecting Mold Inside Crawl Spaces
Our inspections are utilized to identify the presence of mold or mildew behind the insulation, under the vapor barrier, and on the wood supports. Early detection will allow for proper remediation of the mold before the extent of the damage spreads to the overall house.
Using IAQ and Mold Test Results To Design Encapsulated Crawl Spaces
The information collected during the IAQ and mold testing process is used to determine the proper layout of vapor barriers, sealing points, and the option of a crawl space dehumidifier in Raleigh. This will ensure that the encapsulated crawl space will be designed according to the specific needs of your home.
Benefits of Crawl Space Encapsulation
Improved Moisture Control:
Sealing your crawl space will keep excess moisture out, thus decreasing condensation on wood and preventing wood rotting, as well as maintaining stability in your home's indoor humidity.
Reduced Energy Bills:
Encapsulation of the crawl space reduces drafts, thus allowing your heating and cooling systems to be used more efficiently and reducing your energy costs.
Mold Prevention and Cleaner Air:
Insulating your crawl space through encapsulation prevents the accumulation of dust and mold and produces a safer and healthier living environment, and fewer allergies.
Increased Value and Durability:
An encapsulated crawl space improves the strength of your foundation, extends the life of your flooring, and provides additional appeal to your property, making your property a more valuable asset.
Encapsulation & Dehumidifier Installation
Dehumidifiers Help Encapsulation Work Better
More than likely, there is still moisture present in some areas of your sealed crawl space, especially where vapor barriers and vented areas are involved. To help reduce moisture content and to eliminate excess humidity, we can install a crawl space dehumidifier in your Raleigh home.
Sizing and Installing the Dehumidifier
We will evaluate your crawl space (its size, the humidity level, and ventilation) to determine what type of crawlspace dehumidifier your home will require. Then will install the unit in a manner that allows for optimal performance while using the least amount of energy possible.
Long-Term Control of Excess Moisture
With the combination of encapsulation and a dehumidification system in place, you will be assured of long-lasting control of moisture in your crawl space, since you will have greatly reduced the maintenance and growth of mold and other harmful organisms in the space.
Signs Your Crawl Space Needs Encapsulation
Condensation or Standing Water
Pooled water or damp surfaces indicate that moisture control is failing. Encapsulation addresses these issues by blocking sources of water infiltration.
Musty Odors or Allergens
Persistent smells or allergy symptoms often stem from mold spores in the crawl space. Proper sealing and insulation eliminate these hidden hazards.
Mold or Wood Rot in Crawl Space
Visible mold or soft, rotting wood signals structural risk. Encapsulation prevents further decay and improves overall home safety.
High Indoor Humidity or HVAC Strain
Excess humidity and overworked HVAC systems are signs that your crawl space is leaking moisture into living areas. Encapsulation restores energy efficiency and comfort.
