Get answers to common questions about insulation services in Lebanon, New Hampshire.
For our cold climate, the "best" type depends on your home's structure and budget, but air sealing combined with high R-value materials is critical. Blown-in cellulose or fiberglass are excellent for attics and walls due to their ability to fill gaps, while spray foam is highly effective for sealing air leaks in basements and rim joists. The recommended R-values for our zone (Climate Zone 6) are significantly higher than warmer regions, so a professional assessment is key to meeting targets like R-49 for attics and R-20 for basement walls.
Costs vary widely based on the project scope, material, and home size, but Lebanon-area homeowners can expect attic insulation to range from $1,500 to $4,500, while whole-house wall insulation can be $3,000 to $8,000+. Local factors like the age of your home (e.g., historic properties may need special techniques) and accessibility affect price. It's wise to get 2-3 detailed quotes from local, licensed contractors and inquire about available rebates from New Hampshire utilities like Liberty Utilities or NHSaves.
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, which is important for certain materials like spray foam and for ensuring proper attic ventilation. Scheduling in these shoulder seasons also avoids the busy peak of late fall when many homeowners rush to prepare for winter, potentially leading to contractor delays.
For standard retrofit insulation jobs in existing homes, a building permit from the City of Lebanon's Building Department is often not required. However, if the project involves structural alterations, new construction, or changes to electrical/mechanical systems, a permit is likely needed. Always verify with the Lebanon Building Department. Furthermore, reputable local contractors will ensure all work complies with New Hampshire building codes and energy standards.
Attic insulation is one of the most cost-effective upgrades for Lebanon homes, but draftiness often points to air leakage. Before adding bulk insulation, a professional energy audit (available through NHSaves) is highly recommended to identify specific air leaks around windows, doors, rim joists, and ductwork. A comprehensive approach that combines air sealing with adding adequate attic insulation (to at least R-49) will deliver the greatest comfort and savings on your heating bills.
