Encapsulation
What is a crawl space encapsulation?
A crawl space encapsulation includes a full crawl space seal (vents, foundation line, other openings), waterproof wall insulation and a heavy-duty vapor barrier. All of our vapor barriers are made in the USA and are sealed along every seam with vapor bond adhesive.
In our crawl space encapsulations all crawl space vents, foundation lines and penetration points are sealed. Next a heavy-duty vapor barrier is installed covering 100% of the crawl space floor and wrapped up the foundation walls. Then waterproof wall insulation is installed along the interior foundation wall. Lastly, bonding tape is used to seal everything together. A dehumidifier is also installed to circulate and keep the crawl space air clean and humid free. This is used to prevent moisture from building up in the crawl space.
An encapsulated crawl space protects a home from excess moisture that can cause damage. The dehumidifier is used to help to regulate wood moisture and circulate the crawl space air to prevent mold growth and wood rot. At Carolina Casa, as a crawlspace encapsulation company in Raleigh, NC, our specialty is encapsulated crawl spaces.
Insul-Barrier Wall Insulation
When you insulate the foundation walls, insulating the floor joists is unnecessary, so you do not need to worry about doing both. Fiberglass or cellulose insulation between floor joists often becomes damaged by pests or built-up moisture over time. Replacing it is expensive, which is why we offer insul-barrier wall insulation. It is a long-term crawl space insulation solution. It is entirely waterproof, so it can be easily dried, unlike fiberglass if it ever gets wet from a flood or a leak.
What are the benefits?
Decreased energy costs
Prolonged HVAC system life
Reduced humidity levels
Increased home value
Crawl space moisture can make a home an unhealthy, smelly environment that can be structurally unsound if left alone. A crawl space encapsulation creates an insulated foundation and seals a home from moisture and outside air, helping to regulate temperatures indoors more efficiently. Encapsulating your crawl space will extend the life of a home and protect it from damage from excess humidity.
EXCESS MOISTURE
Attracts pests
Promotes mold and mildew growth
Leads to wood rot and cupping floorboards
Creates a hot humid feeling inside

A crawl space encapsulation is an effective method of insulating and sealing off a crawl space to improve the overall energy efficiency and comfort of a home. The process involves creating a barrier between the crawl space and the exterior environment, which helps to regulate temperature and humidity levels. One of the benefits of encapsulating a crawl space is the significant reduction in the risk of pipes freezing during colder months. By maintaining a consistent temperature within the crawl space, homeowners can avoid the costly damage that occurs when plumbing systems succumb to freezing temperatures.
In addition to helping preventing frozen pipes, encapsulation enhances the performance of the HVAC system. When the crawl space is sealed, the air distribution becomes more efficient, leading to reduced energy consumption. This results in lower utility bills and a more comfortable living environment, as conditioned air is retained and distributed more effectively throughout the home. In the warmer months, an encapsulation helps prevent condensation on the HVAC system. This moisture can cause mold growth. Moreover, encapsulated crawl spaces can lead to improved indoor air quality. By reducing moisture and insulating the area, the risk of allergens like mold and dust mites diminishes, contributing to a healthier living space.
The encapsulation process typically involves installing a heavy-duty polyethylene vapor barrier that lines the walls and floor of the crawl space. This barrier is designed to be watertight, preventing moisture intrusion from the ground and minimizing the chances of mold growth. Furthermore, it’s essential to ensure that the space is well-ventilated by incorporating dehumidifiers or vents as needed.
Insulation is also a crucial component of encapsulation. Using high quality, waterproof wall insulation that is installed properly is crucial for the encapsulation to function.
In summary, crawl space encapsulation provides a multitude of benefits, including temperature regulation, energy efficiency, pipe protection, and enhanced indoor air quality. For homeowners interested in improving the functionality of their home, investing in encapsulation can lead to long-term savings and a more comfortable living environment.

The Carolina Casa Encapsulation Process (Our 5-Step System)
We follow a proven, meticulous process trusted by homeowners across Raleigh and the Triangle Area to deliver a reliable, lasting solution.
1. Comprehensive Assessment & Preparation
We start with a thorough crawl space inspection to identify all issues. This includes checking for existing water intrusion, wood decay, pest damage, and measuring current moisture and humidity levels. We then remove all debris, old insulation, and perform necessary mold remediation to ensure a clean slate.
2. Complete Sealing and Air-Gapping
All crawl space vents are permanently sealed with rigid foam board insulation. Any gaps, cracks, or penetrations in the foundation walls or around pipes are sealed using professional-grade expanding foam and caulk to create an airtight thermal boundary.
3. Premium Liner Installation (The Vapor Barrier)
We install a heavy-duty, Viper 12 or 16-mil vapor barriers that are tear-resistant and puncture-proof. This barrier covers 100% of the floor, extends up the foundation walls, and is secured to all pillars. All seams and edges are meticulously taped and sealed using specialized bond tape for a truly contiguous, waterproof liner.
4. Humidity and Moisture Control System
The sealed space is now a conditioned environment. We install a self-draining, energy-efficient, commercial-grade Crawl Space Dehumidifier (such as a Santa Fe or Aprilaire) sized specifically for your home's square footage to maintain optimal humidity levels (typically below 55% RH). In areas with standing water issues, we install a drainage system and sump pump as a critical safeguard.
5. Final Check & Warranty
Our team conducts a final inspection, confirming that the air-sealing and dehumidifier are working perfectly. We provide you with information on your system's performance and schedule your complimentary 6-month follow up inspection.
The Cost and Value of Crawl Space Encapsulation in Raleigh:
Homeowners often ask, "How much does crawl space encapsulation cost?"
While a precise number requires a free on-site inspection, a full-service encapsulation in the Raleigh area typically ranges between $7 to $10 per square foot for a full system, often falling in the $8,000 to $15,000 range for an average-sized home.
This cost is influenced by:
Crawl Space Size & Height: Larger or difficult-to-access spaces require more labor and materials.
Existing Damage: The need for extensive mold removal, structural wood repairs, or deep water management (sump pump/French drain).
Material Quality: We only use premium, reinforced 20-mil liners and energy-efficient dehumidifiers.
Encapsulation is an Investment, Not an Expense:
Saves Money: Lowers monthly energy bills by reducing the strain on your HVAC system.
Adds Value: A sealed, healthy crawl space is a huge selling point that increases your home's resale value.
