Get answers to common questions about insulation services in Marietta, Georgia.
For our humid subtropical climate with hot summers and mild winters, attic insulation is the most critical. Proper attic insulation (typically blown-in cellulose or fiberglass to an R-38 to R-60 level) acts as a primary thermal barrier against intense summer heat, significantly reducing cooling costs. It also helps manage winter heat loss and reduces humidity-related issues like mold in your living spaces.
Costs vary based on home size, material, and accessibility, but a typical attic insulation upgrade for a 1,500-2,000 sq ft home in Cobb County ranges from $1,500 to $3,500. Blown-in cellulose is a common, cost-effective choice. It's important to get itemized quotes from local providers that include air sealing, as Georgia's energy code requires it alongside insulation in many cases for optimal performance.
The ideal times are late fall (October-November) and early spring (March-April). These periods offer milder temperatures, making it safer for installers to work in your attic and allowing your HVAC system to be tested effectively. Scheduling during these shoulder seasons also avoids the peak summer demand, potentially leading to better availability and pricing from local contractors.
Always verify the contractor is licensed by the Georgia State Licensing Board for Residential and General Contractors. Choose a provider experienced with local building codes and the specific challenges of older Marietta homes, such as dealing with knob-and-tube wiring or inadequate ventilation. Look for companies that perform a pre-installation energy audit and provide detailed quotes specifying R-values, material types, and air sealing scope.
Not entirely. While insulation resists heat flow, air sealing is the crucial first step to stop drafts. Gaps around windows, doors, ductwork, and penetrations in the attic floor allow conditioned air to escape. A professional contractor should perform a comprehensive air sealing audit (addressing the "building envelope") before adding insulation. This combined approach is essential for maximizing comfort and energy savings in our climate.
