Many homes in the Charlotte NC area have crawl spaces beneath, designed to raise the building above the ground and give access to contractors as they install HVAC, electrical wiring, and pipework. However, if these crawl spaces are open, they can often suffer from moisture issues, leading to fungal infestation, mold, and even foundation settlement. If unchecked, these issues could compromise the property’s structural integrity and attract termites. All these problems could result in expensive repairs, so many homeowners consider sealing off this area through encapsulation. What do you need to know about crawl space encapsulation, and what should you consider before going ahead with this project?
What Is Crawl Space Encapsulation?
Crawl space encapsulation is the process of adding a strong moisture barrier to the floor, sealing the space completely. Before encapsulation is done, drains are typically installed in order to flush out any unwanted water. After this, a polyethylene product is applied to any surfaces to protect from moisture, with sealing tape used to provide additional protection. This will ensure that the moisture does not penetrate the walls and create longer-term problems. But it doesn’t get rid of the moisture itself. To do this, you should also install a dehumidifier to control the moisture and vapor levels in the sealed-off crawl space.
Our Crawl Space Encapsulation System
Moisture Loc specializes in crawl space encapsulation, providing a total climatization of your crawl space. The GreenSpace™ isour ultimate encapsulation system.This system combats high moisture and humidity levels, mold or mildew, and standing water problems in your crawl space. Because the environment of the crawl space is kept at a reasonable temperature, moisture levels are kept low and mold is prevented. So, our GreenSpace™ Sealed Crawl Space System locks out moisture, sparing the home and homeowners from health issues, hazards, and structural damages that are due to excessive moisture.

SEAL SEAMS OF VAPOR BARRIER
The first step in our sealed crawl space encapsulation is installing a durable poly liner in the crawl space. A 17-mil poly liner is placed along interior crawl space walls, around the interior crawl space piers, and over 100% of the crawl space floor. The liner is taped down and caulked so your crawl space stays fully encapsulated. As a result, moisture doesn’t rise up from the ground and into your floor system, insulation, and home.

SEAL CRAWL SPACE VENTS
The next step in sealing a crawl space is ensuring no humid outside air is getting into your crawl space. We seal the vents with a commercial-grade insulating board so that hot or cold air from outside will not get into your crawl space.

INSULATE WALLS (OPTIONAL)
After sealing the vents, our next step is insulation. 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.

INSTALL ENERGY STAR DE-HUMIDIFIER
A dehumidifier is an essential step in crawl space encapsulation. Moisture Loc uses dehumidifiers that are designed 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 is equipped with a fan that draws in moist, humid air through a cold evaporator coil, therefore cooling the air below its dew point. Once the air is cooled below the dew point, it turns into water, which is collected and automatically drained.

REMOVE FLOOR JOIST INSULATION
If insulation is aged or damaged due to high moisture, it can cause Fungi growth, create cold or hot spots in your floors, and produce energy loss throughout your floors.
By removing the old or damaged insulation and replacing it with new insulation, the heating and cooling properties in your home are improved dramatically and will reduce your risk of Fungi growth.
Benefits of Crawl Space Encapsulation
There are many benefits associated with this process. For example, you can:
- reduce the risk of mold and mildew accumulation
- provide structural protection for the property
- get better air quality in the home
- keep termites and other pests at bay
- and improve your energy efficiency.
If you don’t consider encapsulating the crawl space, be on the lookout for a raft of potential problems other than those mentioned above, including:
- 发霉的气味
- rusting metal
- trapped soil gases in the space
- and buckled hardwood flooring in your living area.
You may not notice problems in the early days, as they may only manifest when the damage has become quite severe. Unfortunately, this can lead to costly repair work, which you need to do before you can encapsulate the crawl space.
What’s the Difference Between Sealing and Full Encapsulation?
Some people think that encapsulation and crawl space sealings are one and the same. However, the latter will only achieve partial protection. With sealing, you cover the floor and the lower part of the wall with a moisture-proof barrier. It’s a less effective approach than full crawl space encapsulation, and you won’t be able to control the moisture and vapor as much. With encapsulation, you cover the ceiling and all the exposed walls in addition to the floor. You will then add a sealant to hold the polyethylene products in place.
Things to Consider Before Encapsulating
Before you get ready to encapsulate, take time to prepare the area. Look at the general drainage system around your house and make alterations as necessary. Ensure that water runs away from the periphery and bring in a drainage company if necessary to help. If the area is already suffering from mold accumulation, get rid of this before you begin. If mold has caused any damage to joists or other structures, bring in the experts to conductcrawl space repairfirst.
Also, take a close look at your combustion appliances and ensure they are properly vented to the outside air. You’ll want to do this before you encapsulate your crawl space to avoid any backdraft from these appliances into your living space.
