We’re a Smyrna-based spray foam insulation contractor who knows the local housing and climate. With summer cooling loads being the main concern in Zone 3A, we focus on air sealing and moisture control to keep your home comfortable year-round.
Why Smyrna Homes Need Spray Foam
Smyrna and Cobb County are filled with bungalows, ranches, and new townhomes built on slabs or crawl spaces. These homes are vulnerable to air leaks and humidity, especially in the hot and humid summers typical of Georgia. Spray foam insulation—especially closed-cell foam—offers an air and vapor barrier that prevents conditioned air from escaping and unconditioned air from entering. This is critical in mixed-humid climates like ours, where high humidity can lead to mold and indoor air quality issues.
Our Spray Foam Services in Smyrna
We offer spray foam insulation services tailored to Smyrna and Cobb County homes. For attic air sealing, we use open-cell foam at ~R-3.5 to R-4 per inch to seal ducts, soffits, and roof penetrations. In crawl spaces, we use closed-cell foam at ~R-6 to R-7 per inch to encapsulate and control moisture. This is especially important in vented crawl spaces, where Georgia’s humidity can lead to mold and rot. For new construction in areas like Smyrna Market Village, we install foam as part of the building envelope to ensure long-term energy efficiency.
What It Costs in Smyrna
Costs vary depending on access, thickness, and whether removal is needed. On average, attic insulation with closed-cell foam ranges from $3,000 to $6,750, while open-cell is usually less. Crawl space encapsulation with closed-cell foam typically costs between $2,400 and $5,400. A combined attic and crawl space project can range from $3,000 to $8,500. Georgia Power offers rebates for qualified insulation upgrades, though these vary annually.
