Get answers to common questions about insulation services in Newmarket, New Hampshire.
For our cold New Hampshire winters, properly insulating your attic is the single most impactful upgrade. Heat rises, and a poorly insulated attic allows significant heat loss, leading to high heating bills and ice dam formation on roofs. We recommend achieving at least R-49 to R-60 in the attic, typically using blown-in cellulose or fiberglass, which also helps seal air leaks common in older Newmarket homes.
Yes, New Hampshire homeowners have excellent incentives. The primary program is through NHSaves, which offers rebates for adding insulation and air sealing to meet prescribed R-value targets. Additionally, Newmarket residents served by the Newmarket Community Development Corporation or Unitil may have access to local energy efficiency programs. We always advise checking the NHSaves website and consulting with your insulation provider, as rebates can significantly offset project costs.
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 attic work and allows contractors greater availability. Scheduling in these windows ensures your home is fully prepared before the intense heating season begins, though it's wise to book several weeks in advance as local contractors fill up quickly.
Always choose a contractor licensed to operate in New Hampshire. Look for companies with strong local references, proper insurance, and certifications from manufacturers like Owens Corning or CertainTeed. A reputable provider will perform a thorough energy audit or assessment before quoting, focusing on air sealing alongside insulation—a critical step for our climate. Be wary of door-to-door sales or quotes that seem unusually low without a detailed inspection.
Not entirely. While wall insulation (like dense-pack cellulose) is important, air sealing is the first and most critical step for drafty older homes. In Newmarket's historic housing stock, air leaks around windows, doors, sill plates, and electrical outlets often cause more discomfort and energy loss than insufficient insulation. A professional assessment will identify these leakage points; sealing them, then adding insulation, creates a comprehensive thermal barrier that maximizes comfort and efficiency.
