Get answers to common questions about insulation services in Charlestown, New Hampshire.
For Charlestown's cold New Hampshire winters, focusing on air sealing and attic insulation is critical. We recommend high-performance materials like spray foam for air sealing and dense-pack cellulose or fiberglass batts for attics to prevent significant heat loss. Properly insulating your basement or crawlspace walls is also vital to combat ground frost and moisture common in our region.
Yes, New Hampshire homeowners can access excellent incentives through the NHSaves program, which offers rebates for air sealing and adding insulation to meet specified R-value targets. Additionally, the federal Inflation Reduction Act provides tax credits for qualified energy efficiency upgrades. A local, certified contractor can help you navigate these programs to maximize your savings.
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, which is optimal for projects like attic work. Scheduling during these shoulder seasons also ensures your home is prepared before the severe winter cold sets in, and contractors' schedules may be more flexible than in peak summer or late fall.
Always choose a contractor licensed to work in New Hampshire and insured. Look for companies with specific experience in our climate and ask for local references in Sullivan County. It's also highly recommended to select a contractor who is a certified installer for the products they use and who performs a pre-installation energy assessment to identify your home's specific needs.
Yes, moisture management is a critical concern, especially in New Hampshire's humid summers and snowy winters. A professional assessment is essential to identify and address existing moisture issues, ensure proper attic and crawlspace ventilation, and select vapor-permeable materials where appropriate. The goal is to create a thermally efficient yet dry building envelope to prevent mold and rot.
