Get answers to common questions about insulation services in Hanover, Connecticut.
For Hanover's cold winters and humid summers, a combination of air sealing and high-performance insulation is critical. We recommend focusing on the attic first, using blown-in cellulose or fiberglass to achieve at least R-49, and ensuring basement rim joists and crawl spaces are sealed and insulated to prevent cold drafts and moisture issues common in Connecticut's variable climate.
Costs vary by home size and scope, but a typical attic insulation project in Hanover ranges from $1,500 to $3,500. Whole-house air sealing and insulation can range from $5,000 to $15,000+. It's important to note that Connecticut offers rebates and financing programs like the Energize CT Home Energy Solutions service, which can significantly offset the upfront cost for eligible homeowners.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather in Hanover, which is optimal for attic work and allows contractors more scheduling flexibility before the busy winter rush when homeowners feel the urgent need for upgrades.
Always verify the contractor is licensed and insured in Connecticut. Look for a company experienced with Hanover's older home stock and knowledgeable about the state's building codes and energy programs. A reputable provider should perform a thorough energy audit first, offer detailed proposals, and be certified by manufacturers like Owens Corning or Johns Manville.
Not entirely. In older New England homes, air leakage is often the primary culprit. A comprehensive approach that includes professional air sealing of gaps, cracks, and bypasses in the attic, basement, and around windows/doors must be done *before* adding new insulation. This combination is essential for eliminating drafts, improving comfort, and maximizing the effectiveness of your new insulation.
