Quick answer: Spray foam insulation in Marietta costs $1.00–$1.60 per board foot for open-cell and $1.60–$2.60 per board foot for closed-cell. Most homeowners pay $3,000–$8,500. Most jobs finish in one day. Final pricing depends on access, required thickness, and any removal of existing insulation.
We install spray foam in Marietta homes. Our work keeps historic Marietta Square homes, East Cobb ranches, and new subdivisions more comfortable year-round. Here’s how it helps Cobb County homes in a cooling-dominated climate like ours.
Why Marietta Homes Need Spray Foam
Marietta homes, whether built on slabs or with crawl spaces, face long, hot summers and high humidity. The IECC Zone 3A climate means cooling loads are heavy, and traditional insulation often fails to block air and moisture. Spray foam, especially closed-cell, creates a durable air and vapor barrier that stops hot, humid air from leaking into homes. This is crucial for attic spaces that bake under the Georgia sun and crawl spaces that trap moisture.
Our Spray Foam Services in Marietta
We specialize in attic air sealing and insulation, crawl space encapsulation, and new construction foam installation. For attic spaces, we often use open-cell foam for air sealing and insulation, which helps reduce cooling loads and prevents hot air from entering the living space. In crawl spaces, closed-cell foam is our go-to because it resists moisture and provides a vapor barrier, which is essential in Georgia’s humid climate. We also work with new subdivisions to install foam during framing, ensuring energy efficiency from the start.
What It Costs in Marietta
Spray foam insulation in Marietta typically ranges from $3,000 to $6,750 for attic air sealing and insulation, depending on whether you choose open-cell or closed-cell foam. Crawl space encapsulation with closed-cell foam usually costs between $2,400 and $5,400. Combined projects, such as both attic and crawl space, can range from $3,000 to $8,500. The final price depends on the size of the area, access, and whether old insulation needs removal.
