Average Costs of Crawl Space Encapsulations in NC & SC

The total cost of crawl space encapsulation can vary significantly based on the issues present and the steps needed to control moisture, humidity, and cleanliness. A complete encapsulation, including vapor barriers, mold removal, drainage systems, and dehumidifiers, can range from $13,000 to $20,000 or more, depending on the home's size and complexity. Since each home has unique challenges, not all require the full range of services, meaning the cost could be much less. This is why getting a crawl space evaluation is essential—it helps pinpoint exactly what all is needed to achieve the desired results.

Factors Affecting Crawl Space Encapsulation Costs

• Condition of Crawl Space: Pre-existing issues like mold or water damage may need to be addressed before encapsulation, adding to the cost. On the flip side, a crawl space that is relatively clean and dry with no major issues could see lower costs, as there will be fewer steps required prior to encapsulation.
• Drainage Solutions: If your crawl space requires drainage systems (e.g., French drains, sump pumps), this will add additional costs for installation.
• Dehumidification Systems: Adding a dehumidifier or an advanced climate control system to the crawl space can increase the overall cost.
• Materials Used: The type of encapsulation materials you choose (e.g., drainage systems/sump pumps, vapor barriers, dehumidifiers) can also affect the price, as high-quality, durable materials may have a higher initial cost but could save money in the long run by preventing future issues.
• Existing Insulation: Damaged or outdated insulation may need to be removed or replaced.
• Size of the Crawl Space: Larger spaces may require more materials and labor, influencing the overall cost.
• Accessibility of the Crawl Space: Crawl spaces that are harder to access may require more labor or specialized equipment, increasing installation costs.
• Permits and Inspections: Depending on local building codes, you may need permits or an inspection, which could add to the total cost of the project.

What is a Crawl Space Encapsulation?

Crawl Space Encapsulation is a home improvement solution that transforms a moldy, musty, and damp crawl space into a clean, dry, and healthy area. This process involves sealing off your crawl space to protect it from moisture, mold, and pests, ultimately enhancing the overall air quality of your home. Below is a breakdown of what the crawl space encapsulation process entails:

• Water & Mold Removal: Pre-existing conditions such as mold or water damage must be addressed prior to the encapsulation process. Groundwater and mold can threaten the air quality and structural integrity of the space.
• Drainage System Installation: If necessary, a proper drainage system, such as a sump pump, is installed to manage and remove any water and moisture effectively.
• Lining the Crawl Space: The floors and walls of the crawl space are lined with a thick material (called a vapor barrier) that prevents moisture and growth of mold. This barrier is sealed tightly at all seams and attached to the walls, effectively creating an impermeable layer that prevents moisture from the ground and outside air from entering the space.
• Sealing Vents and Gaps: All vents and external gaps are sealed to stop the inflow of humid air and pests into the crawl space.
• Insulation: Walls and sometimes the ceiling of the crawl space may be insulated if needed to help maintain a consistent temperature within the space and the floors above it.
• Whole Home Dehumidifier Installation: In many cases, a dehumidifier is installed to control the moisture level within the encapsulated crawl space & home, further preventing mold and mildew growth.
• Custom Crawl Space Door: At GSM Services, a custom crawl space door is offered, designed not only to enhance the aesthetic appeal but also to improve energy efficiency under your home.

Is a Crawl Space Encapsulation Worth the Investment?

Explore the long-term benefits of crawl space encapsulation against the initial investment. This section discusses potential savings on energy bills, air quality improvements, enhanced home comfort, and protection against structural damage.

• ✅ Improve Air Quality: By sealing off sources of moisture and potential allergens, encapsulation can significantly improve the air quality throughout your home. Since the air from underneath your home can no longer find its way inside, you will no longer be breathing in the outside dust and allergens! Many customers have reported a substantial reduction in allergy flare-ups as a result.
• ✅ Prevent Moisture & Mold Issues: By fixing the humidity levels in your home and underneath the crawl, you create an environment that mold and other spores simply cannot survive in. Preventing moisture-related issues such as mold, wood rot, and mildew, which can compromise the structural integrity and air quality of your home.
• ✅ Increase Energy Efficiency & Lower Power Bills: An encapsulated crawl space helps in maintaining more consistent indoor temperatures, reducing the workload on heating and air conditioning systems and potentially lowering energy costs.
• ✅ Improve Comfort Levels: Did you know that around 40%-60% of the air that enters your home comes from your crawl space? An encapsulated crawlspace can help with fixing uneven temperatures, clammy and damp feeling inside the home.
• ✅ Increase Home Value: Crawl Space Encapsulations are an investment! Homes with encapsulated crawl spaces are often valued higher due to the improved preservation of the structure and the added benefits in terms of energy efficiency and air quality.
• ✅ Assist with Future Pest Prevention: The encapsulated environment is inhospitable to termites and other pests, which reduces the chance of termite or bug infestations. This helps to protect the structure & home enviroment.
