Benefits of Crawl Space Insulation in North Carolina
Insulating your home’s crawl space might not be the most glamorous home improvement project, but it can significantly impact your comfort and energy bills. Here are some of the benefits of insulating your home’s crawl space:
Improved Energy Efficiency
When your crawl space is insulated, it can help prevent heat from escaping in the winter and entering in the summer. That means your HVAC system won’t have to work as hard to maintain a comfortable temperature inside your home, which can lead to lower energy bills.
Increased Comfort
Insulating your crawl space can also make your home more comfortable year-round. When your floors are warmer in the winter and cooler in the summer, you’ll be more comfortable walking around barefoot or sitting on the floor to play with your kids or pets.
Reduced Moisture and Humidity
Crawl spaces are notorious for being damp and humid, leading to many problems, including mold and mildew growth, wood rot, and insect infestations. Insulating your crawl space can help keep moisture at bay, which can help protect your home from these types of issues.
Improved Indoor Air Quality
When your crawl space is damp and humid, it can create conditions ideal for mold and mildew growth. That can lead to musty smells and poor indoor air quality. Insulating your crawl space can help reduce humidity levels and improve the air quality inside your home.

Considerations for Crawl Space Insulation in North Carolina
Before crawl space insulation in North Carolina begins, there are important factors we consider for the best result. As a start, we check whether your crawl space is vented or unvented and decide how to insulate it.
Insulating Unvented Crawl Spaces
For unvented crawl spaces, we recommend applying spray foam insulation to the walls of the crawl space. That creates an air barrier that helps to prevent air leakage, which can be a significant source of energy loss in a home.
Insulating the walls of an unvented crawl space also makes it part of the home’s conditioned space, contributing to more consistent temperatures.
Spray foam insulation also has a high R-value per inch, which means that a relatively thin layer of insulation can provide excellent thermal protection.
Insulating Vented Crawl Spaces
For vented crawl spaces, spray foam insulation can be applied to the underside of the subfloor. That creates an air seal that prevents air from leaking into the living room. Moreover, doing so ensures that moist air in the crawl space isn’t trapped, which would otherwise cause condensation and moisture problems in the long run.
Closed-cell spray foam provides excellent thermal protection, prevents air leakage, and, most importantly, helps control moisture. It acts as a moisture barrier, preventing moisture seepage from outside and condensation of moist air in the crawl space.
Our North Carolina Crawl Space Insulation Process
Installing insulation in North Carolina is unlike other insulation projects. Proper preparation of the crawl space before installing insulation is crucial for ensuring a successful installation and long-term performance. Here are the steps involved in our insulation of crawl space process:
Clean and remove debris: Our insulation experts remove debris, such as rocks, wood scraps, or old insulation, from the crawl space. That helps create a clean environment for installing the insulation.
Address any moisture issues: Before installing insulation, address any moisture issues in the crawl space. That may involve repairing any leaks or installing a vapor barrier on the floor to control humidity levels in the crawl space.
Identify air leaks: Air leaks can lead to energy loss and reduced insulation performance for unvented crawl spaces. Applying spray foam air seals and insulates the crawl space simultaneously
Install a pest barrier: For homeowners living in areas with rodent or insect issues, we recommend installing a pest barrier to prevent them from entering the crawl space and damaging the insulation.
Ensure proper ventilation: For vented crawl spaces, we make sure they are open and unobstructed. That improves airflow and prevents moisture build-up in the crawl space.
Check for structural issues: We inspect the crawl space for structural issues, such as damaged floor joists or foundation cracks. We recommend that any repairs be done before installing insulation to ensure the structural integrity of your home.
Spray foam application: Once the preparations are done, our spray foam experts apply spray foam on the walls or the subfloor underside, depending on the type of your crawl space.

Maintaining Crawl Space Insulation in North Carolina
Proper maintenance of insulation in crawl spaces is essential for ensuring that it performs effectively and lasts as long as possible. Here are some best maintenance practices for insulation in North Carolina:
Check for signs of moisture, including puddles, mold, or dampness
Inspect for insulation damage
Ensure vents in the crawl space are unobstructed
By inspecting the crawl space regularly for moisture issues and damage, you can ensure that your insulation performs effectively and lasts for many years. You can also consult with our spray foam professionals for guidance on maintenance and any necessary repairs or replacements.
