Why Lawrenceville Homes Need Spray Foam
Lawrenceville is in IECC Zone 3A, a mixed-humid climate where cooling dominates. Many homes in the area have vented crawl spaces, which trap moisture and raise energy bills. Spray foam offers a long-term solution by sealing air leaks and controlling humidity, especially in older homes and newer subdivisions with open-cell or inadequate insulation.
Our Spray Foam Services in Lawrenceville
We specialize in both attic air sealing and crawl space encapsulation. For attics, we use open-cell foam for air sealing and closed-cell for added moisture control. In crawl spaces, closed-cell foam is ideal due to high humidity and potential for mold. We also support new construction, ensuring air-sealed envelopes from the start. Every job is tailored to the specific needs of your home and the Lawrenceville climate.
What It Costs in Lawrenceville
Spray foam insulation costs in Lawrenceville vary based on access, thickness, and whether we remove old insulation. A typical attic job with closed-cell foam runs $3,000 to $6,750. Open-cell is less expensive, but offers lower R-value. Crawl space encapsulation costs between $2,400 and $5,400. Combined attic and crawl space jobs range from $3,000 to $8,500. Georgia Power offers rebates that can offset some costs, but these vary annually.
