Get answers to common questions about insulation services in Newington, New Hampshire.
For our climate, the "best" type depends on your home's structure and the area being insulated. For attics, blown-in cellulose or fiberglass is highly effective for achieving the recommended R-49 to R-60 levels to combat our long heating season. For walls (especially in older Newington homes), dense-pack cellulose or injection foam are excellent choices to reduce air infiltration and heat loss. A professional assessment is key to determining the right material and R-value for your specific project.
Yes, New Hampshire homeowners can access significant incentives through the NHSaves program, which is funded by the state's utility companies. These rebates apply to air sealing and adding insulation to meet specific R-value targets, directly lowering your project cost. Additionally, the federal Inflation Reduction Act offers tax credits for qualified energy efficiency upgrades. A reputable local insulation contractor will be familiar with these programs and can help you navigate the application process.
While insulation can be installed year-round, the best times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather in Newington, which is ideal for attic work and allows for proper ventilation during installation. Scheduling during these shoulder seasons also helps you avoid the busy winter rush, ensuring your home is properly sealed and insulated before the coldest months arrive.
Look for a contractor who is licensed and insured in New Hampshire and has specific experience with homes in the Seacoast region. They should provide a detailed, written estimate that includes a scope of work, materials (with R-values specified), and labor. Ask for local references and check reviews. Crucially, ensure they perform a thorough assessment, including a blower door test for air leakage, to diagnose your home's specific needs rather than offering a one-size-fits-all solution.
Not entirely. In older homes, air sealing is actually the first and most critical step. Insulation slows heat transfer, but drafts (air leakage) allow conditioned air to escape directly. A comprehensive approach involves sealing gaps, cracks, and bypasses in the attic, basement, and around windows and doors first. Then, adding the proper levels of insulation will work effectively. This combination is essential for maximizing comfort, energy savings, and preventing moisture issues in our humid summers and cold winters.
